Firefox 15.0.1 Constant Crashing Windows 7 64bit

I am running Windows 7 64bit, Firefox 15.0.1 and all my addons are up to date. I have two extensions installed - AVG Do Not Track and Adblock. I have eight pluggins installed and three are normally disabled - Adobe Acrobat10.1.4.38, Google Update 1.3.21.115(Disabled), Java Deployment Toolkit 7.0.70.10 10.7.2.10, Java(TM) Platform SE 7 U7 10.7.2.10, Microsoft Office 2010 14.0.4761.1000(Disabled), Microsoft Office 2010 14.0.4730.1010(Disabled), Picasa 3.0.0.0, Shockwave Flash 11.4.402.278. I do not want to roll back the display driver because it fixed a display issue that caused a distortion in my monitor. So what are my options? Is it even the display driver? I have included my crash reports to assist in troubleshooting the issue.

Hope I am not TOO hostile in my reply here but you have to understand I am frazzled after trying to resolve this issue for 4 days now... constant crashing on 15.0.1 and on 14.XX.X.
I thought I might find an answer here, but I am amazed to see people continue to reference articles that require you to have FF '''RUNNING''' in order to perform any troubleshooting or analysis.
Come on guys... READ the posts before you reference an article that is moot because it requires FF to work in order to follow it! if we could get it stable enough to run... the issue would e easier to localize and identify!

Constant crashes, windows won't come forward, images won't load

With every version of Firefox, the program malfunctions more. First, I get "(Not Responding)" constantly. Sometimes I end the process and restart FF, but at other times it crashes on its own and I get the Crash Reporter. Starting a few updates back, many images in many web pages stopped loading. Most recently, windows won't come forward. Just now I restarted Firefox and there are 13 windows open altogether. However, 11 of them won't come forward when I click on their tabs in the task bar. The best version of Firefox was version 2. Since then, it has been all downhill.

Unfortunately nothing useful in your crash reports.

do not know what's going on but the Firefox crashing, and is still crashing, and crashing back again ..
This problem is not resolved for a long time 'and I wonder why not fix this problem so far?

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.
To help us diagnose and fix the problem, you can send us a crash report.

I was having the same problem.... But I keep forgetting that when you upgrade firefox... or it updates automatically... you need to right click on the firefox start up icon, go into properties, click on the compatibilities tab, and put a check in the "Run This Program As An Administrator" box, then hit apply. Start Firefox, and it should work OK. Problem is...each time you upgrade firefox and/or I think Adobe flash... you need to make sure that box is checked. This is on Firefox 15.0.1 with Adobe Flash 11.4.402.278 all up to date, Windows 7 64bit. If Firefox has Adobe flash add-on, it needs to run in admin mode or it will crash.

Constant crashing; I think Mozilla on my new Windows 7 thinks it's still operating in XP, although I'm not sure, being computer challenged.

Ever since I started using Mozilla Firefox on my new Windows 7 computer it has crashed -- sometimes a few times a day, sometimes every ten minutes. I will copy the error message details at the end of this, if I can. I have tried numerous technicians and no one has been able to solve it. (I did reset Firefox more than once.) Just today, right clicking on the Firefox icon and going to compatability, I discovered that "Windows XP" was in the window instead of Windows 7. With the help of a Frontier technician (my internet provider) I changed that from Windows XP to Windows 7. We rebooted the computer, hoisted up Firefox, right-clicked on the icon, and sure enough it said "Windows 7" in the compatability window. However, after a short while Firefox crashed again. Right-clicking on the Firefox icon, I saw that it had reverted to "Windows XP" in the compatability window. Questions: Would Firefox's confusion about whether it was on a Windows XP or a Windows 7 computer cause crashes? Why would Firefox's compatability window revert from Windows 7 back to Windows XP? I have a theory, but I am not an expert: A local technician came in and transferred my Firefox from my WIndows XP computer to my WIndows 7 computer. I don't know whether he installed Firefox from your website or simply transferred the program from my XP computer. However, I asked him to keep my bookmarks. I have an icon on my Windows 7 computer: "Old Firefox Files." I thought that these files (there are four of them, all containing pretty much the same thing) were just my bookmarks, but looking at them today, it looks to me as if they contain the whole Firefox program from my XP computer. My inexpert theory: Firefox is reverting from WIndows 7 to Windows XP because my transferred bookmarks are XP-based. A Frontier technician today suggested I uninstall and re-install Firefox. Sounds like a good idea to me, however I am afraid that my old bookmarks will again confuse Firefox about whether it's in an XP or Windows 7 OS. Bookmarks are essential to the way I use my computer. In fact, many technicians suggested that I use Chrome instead of Firefox, but Chrome does not have an easily accessed bookmark list, like Firefox does in its vertical bookmark window. (Also, I would rather not have anything to do with Google.) Of course, I may be completely wrong about it being my bookmarks and the files transferred from my XP that are screwing up Firefox. Basically: Constant crashes and error messages; compatability window reverts from Windows 7 to Windows XP for some reason; bookmarks and other old Firefox program files have been put on this Windows 7 computer. What do you think I should do to keep Firefox from crashing?
Here (hopefully) is the error message I get when Firefox crashes. It crashes no matter what website I am on at the moment:

Your whole bookmarks story is very confusing to me. Perhaps someone else can explain that better. :)
Can you give me your crash reports?

FIREFOX 26 changed the 'post crash' page with the list of windows and pages. It was a real HTML page with links for each page. Now it isn't (and blows)

* You changed the page that comes up after a crash - the one which shows the windows and pages that were up before the
crash.
This used to be a real HTML page and it isn't any more. THis choice was pure isiocy consider how peopel used that page every day (try taking to your users for a change).
The pages listed on that 'post crash page' used to be actual LINKS (you could right click them &
manually open them in another tab - and most peope DID that every day). You could also (and I did this a lot) drag a second
copy of the page, into a new tab (to keep track of all the pages I had not wanted to open)
Now the pages are no longer links. You cannot right-click them.
The thing in the probser is no longer a page that I can drag into a new tab.
Roll the version back and throw this one in the bin...and have a good long talk with your developers about the definition of
'STUPIDITIY'
Then I try to type anything in the addres bar it is suppose to repoond with the history of old things I have types in the past, or
search for what I type (and in some cases I think it tyes to convert it intoa URL). However it no longer does any of these
things. When I type in the ADDRESS BAR ONLY, I do not get all of my letters to appear. I have to type into a notepad or
into the search and to copy and paste to go to a URL. Nothing that is typed into the address bad responds normally at all
anymore, and I am fairly certain there are no new addons on this machine at all. It does not matter which things I disable. It
still does this. W of course points the finger back at a change to FIREFOX. I wich I could just sitct with one stable release
forever but the MOZILLA folk thing it is best to force peopel awy from a working broswer release to a horrible one (due to it
being out of date).
FIREFOX 26.0 has 'issues' (ie new *features*/bugs)
1) History is no longer accurate. My Proof? This machine is the primary one for the entire family (the only PC working). It is
logged in with same user every time and never has its history cleared. It now January 7 so I ought to have a list of all of last
months browing available to me.
However, according to FIREFOX history, in all of December 2013, the entire family only went to 51 primary URL's. None of
the official TV sites I use to get episodes are listed. None of the official movie sites I use are listed. The primary URL for
ebay is not listed. Only 1 out of our 4 weather sites that I use (at least once a week) are listed. Only 1 of our 3 FINANCE
sites is listed. There ought to be several; hundred root URLs listed.
Please fix history as this change seriously "blows greasy chunks"
PROBLEM (a stupid change in the new FIREFOX version)
FOr a long time, after a crash you got a useful page (a real HTML page) which gave you a list of all of your last sessions
'winwos and tabs' that were open when the browser crashed. there were certain ways of using this page that are no longer
able to be done.
The old method was wonderful as it had this behavior :
*** The old method for displaying your 'Recovered Tabs' allowed you to :
a) right click an individual item and open it in a tab without getting rid of that lovely window of your previous session of
'recovered windows and tabs '.
2) drag the URL for the entire window of 'recovered windows and tabs ' to a new tab (to make a second copy) so that you
could select just a few of them to open as a group, and stil have the old list handy.
You can no longer do either of these things. The 'recovered windows and tabs ' page no longer has links in it and can no longer be dragged, so you cant select a few of them to use, and keep the rest around for later. NOW - once you choose which pages to open the window is gone forever (can can't get a second copy).
People used to make a copy of the page for later use (with a drag)
we also used to open pages with a right click (which no longer functions
This new method seriously blows big greasy chunks. A parge loss in function has occurred.
Put things back as they were. 26 is full of terrible changes that NOBODY likes. It also has a lot of bugs (history is not reliable at all)

(1) Firefox's built-in post-crash page has not been a real HTML page for a long time (for example, from the time of Firefox 22, see: [https://support.mozilla.org/en-US/questions/968212 Want to save LOTS of versions of "Restore Session.xht" from the "oops ..." page for later use]). If you had this working differently with Firefox 25, that might have been created by an extension.
You can check to see whether extensions are disabled or need an update on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. The disabled extensions cluster toward the bottom of the list. To poll for updates, use the "gear" button above the list and choose Check for Updates.
If you used the Reset feature (or Firefox automatically did a reset due to some problem during upgrading), you will need to reinstall missing extensions. The reset feature creates a folder on the desktop named Old Firefox Data. Do you have that folder? There may be data you can recover from it.
(2) There are many ways for history to get cleared, both internal to Firefox and external. Could you double-check your Privacy settings?
orange Firefox button (or Tools menu) > Options > Privacy
* The "Firefox will" drop-down says Remember History: Firefox shouldn't be clearing history, but an add-on or external software could do it
* The "Firefox will" drop-down says Use custom settings for history: inspect the "Clear history when Firefox closes" setting to make Firefox isn't set to clear history. Also check your add-ons and consider external software.
Firefox normally accumulates months of history. However, some of Firefox's database sizes are based on disk space available. If your hard drive is very full, Firefox might reduce the amount of history stored.

I just updated to 4.0.1 and I get the "We're sorry. Firefox had a problem and crashed. We will try to open your tabs/windows when Firefox restarts" However, it just keeps popping back up, firefox never restarts!!!

This morning I had a popup on my Windows XP PC stating that the 4.0.1 update was available. I upgraded. now, i receive the following error: We're sorry. Firefox had a problem and crashed. We will try to open your tabs/windows when Firefox restarts. You can submit crash report data, blah blah blah (which i have submitted several)
But, firefox DOES NOT ever open. It just pops back up with that same report window, over and over.

It is possible that there is a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

Firefox loading/crashes/window Problems

So i only started having problems since FireFox 4 came out. When i first got that my firefox would flip out and close randomly. When i would try to reopen it, it would say a file was missing, so i would uninstall and reinstall, again it would work for abit then close then say a file was missing (also didnt care for the settings of firefox 4 either :\ ) So i decided id go back to firefox 3 for now til maybe some bugs were fixed in 4. Ive never had a problem with it before, and for last few days havent had any problems either. Today though firefox would refuse to open a new window. It would freeze if a page had a link to a new window and i would have to use windows manager to shut it down. If i would try right clicking on the firefox icon and click open new window it opens up my files window o.O It opens up Computer/Acer(C:)/Windows/system32 This has lots of files and stuff in it, non of which i know are involved with Mozilla. Ive been trying to be patient and reinstall, redownload, search forums, for anything to help fix this. Bit its not like i know exactly what it is. Im finding myself using Enternet Explorer lately (blah cant get use to it xD i misses firefox after 5 mins). Hope someone can help me, ill leave some computer information incase its my fault :\
Note: Main reason i dislike 4 atm is because it doesnt like alot of my programs especially my virus program Norton which i like seeing it scan pages before i go to them and now it doesnt do that with 4.
Acer Computer
Windows 7
Updates all plugins (incase that was problem)
I dont have a firefox account till now since i made one to post. Will proly try that, but id still like to know why this happens without an account profile
Thank you again and hope to hear back something soon :)

I have the same problem. I've never been able to identify when it started. Once firefox crashes, mpd, if it was playing, becomes unresponsive. The only way to get a flash site working again is to reboot my computer.
I uninstalled flash: I'm not going to put up with that kind of behaviour. Now I watch youtube videos on other people's computers --you know how they say "You've GOT to see this movie!". And if I really need to see that one specific video, there's youtube-dl.
Unfortunately gnash doesn't work on youtube for me.

Firefox crashes windows 7 when recovering from sleep mode

Similar to the following:
http://support.mozilla.com/pl/forum/1/627872?s=window+7+crash&as=s
but not sure whether it depends on pages that are currently opened.
Sometimes, when recovering from sleep mode on win7 (with only Firefox and VS2008 running), win7 crashes. What's important - It doesn't happen always, but still, it's annoying (Firefox starts with startpage only).
I've been noticing this issue on different Firefox versions from Firefox 3.5 to 3.6.6.

Same exactly problem here, very annoying when the computer goes to sleep mode and then Firefox locks up.

Since upgrading to FF 4, I have constant crashes (updating graphics drivers did not help). now all my bookmarks are gone. When I try to restore them, I get error message: "Unable to process the backup file".

Since I "upgraded" to FF 4, I have constant crashes (I tried updating my graphics drivers--it did not help) and now all of my bookmarks have disappeared. When I try to restore them, I get this error message "Unable to process the backup file". I have lost years of bookmarks...please help.
I am using Windows XP, SP 3 if that matters.

I am also unable to restore any of the backups of the bookmarks, both automatic backups and two backups that I created manually. Since I was able to restore backups before, and since no changes have occurred to these backup files, the problem must be with Firefox.
Right before my bookmarks disappeared, FF crashed and I accidentally started FF 3.5. When I saw what I did, I ended the Firefox process and started FF 4. That's when all my bookmarks were gone and I discovered I couldn't retrieve any backups. I did note that an add-on was updated when I restarted FF. Maybe that's the problem. Does FF have a Safe mode?

Firefox 15 runs extreeeeeemly slowly on Windows 7

System:-
Windows 7 v6.1 SP1
Intel 17-3770 CPU @ 3.4GHz
8Gb RAM
Firefox 15.0.1
Firefox runs much slower than on my old Pentium3 PC!
On my old PC I found that Flash 11.3 caused so many Firefox crashes that I just could not play my favourite game on BBO and no amount of removal or down-grading of Flash solved the problem. I gave up and bought a new PC!
NOW I find that Firefox is so slow it is unusable!

Trouble shooting:-
I followed some advice I found in the support forum, particularly from:-
“Update to 15 caused computer to run really slow....” [/questions/935835] link added -J99
I reset Firefox to default settings – no change
I disabled hardware acceleration – no change
I started Firefox in safe mode - Eureka!
Safe mode pointed to a problem with a plugin so I followed section 5 of
#[https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems?redirectlocale=en-US&redirectslug=Basic+Troubleshooting#os=mac&browser=fx15]
# '''Edit'''General link [[Troubleshoot and diagnose Firefox problems#w_5-troubleshoot-your-plugins]]_5-troubleshoot-your-plugins
*1st link is Mac on fx15, 2nd link should match a thread readers OS & fx version -J99
Further research led me to [http://kb.mozillazine.org/Flash#Disabling_Protected_Mode_in_Flash_11.3]
Disabling Protected Mode in Flash 11.3 You can disable Protected Mode in Flash 11.3 (or above) by adding the line ProtectedMode=0 to the Flash "mms.cfg" file located in: (Windows 32bit) C:\Windows\System32\Macromed\Flash (Windows 64bit) C:\Windows\SysWOW64\Macromed\Flash For example, on a Windows 7 64-bit system, open the C:\Windows\SysWOW64\Macromed\Flash folder, copy the file "mms.cfg" to the desktop, open it in Notepad, add a new line ProtectedMode=0 and then close Notepad, saving your changes. Next, go back to the C:\Windows\SysWOW64\Macromed\Flash folder, rename the original file to "mms.cfgBAK" (to save it as a backup) and then drag and drop in the modified "mms.cfg" file from the desktop. [30] [31] [32] [33] [34] [35] [36] Note: To re-enable Flash Protected Mode, either restore a backup of the original mms.cfg file, if you saved one, or else re-edit the mms.cfg file to remove the ProtectedMode=0 line you added. Updating Flash Player or installing a newer version does not automatically re-enable Protected Mode. [37] [38]
This workaround has fixed my problem, looking forward to a version of Flash that works!!!
Hope this helps other folk

Upgraded to 6.0.2, now get "Firefox had a problem and crashed". Starting in Safe Mode does not help. Now what?

Not sure what version I was running, but it worked fine but I have not been able to get it running again. I have uninstalled and reinstalled with the same results. Have followed the help pages to the point of obtaining the Crash Report... now what?
I did notice the CR seems to think I am running Windows XP but I am actually running Windows 7 (64 bit).

That gives Firefox 6.0.2 Crash Report [@ nsHttpHandler::QueryInterface(nsID const&, void**) ] https://crash-stats.mozilla.com/report/index/d2eddeb0-5845-4c72-987a-ad0282110917
Unfortunately that is not really getting anywhere yet, you could become the first person to file a bug about that particular crash, but that takes a bit of time and testing.
There is a known problem causing firefox 6 to crash and that is the use of IDvault, that can give more than one crash signature, the software developers regarding ID vault are WhiteSky, and are expecting to release a fix in a few days (if they have not already done so)
Have you tried
* using firefox's [[safe mode]]
* disabling all plugins
Does that help, either by preventing crashes or giving another recognised crash signature. You should also ensure all software is up to date, before trying adding extension software back.
The other common cause of crashes is malware, that includes a particular Trojan that is now known to crash Firefox 6. Check out [[is my firefox problem a result of malware]] you will need to do scans using software or sites with up-to-date scanning software, if you do scan for problems say what sites or software you used and the version of software used. Downgrading firefox versions rarely helps with crashes, it may help with the one specific trojan, but the security risks would then remain, potentially causing even more problems because the browser no longer crashes.

My computer restarted automatically, and since then, Firefox refuses to load, it crashes instantly as I try to open it, I cannot access any of its options that way. What can I do?

Last night, as I was asleep, my computer restarted automatically, most likely due to an update of some sort. Usually, that is not a problem, as everything works just fine afterwards. HOWEVER, this time, it was not the case. Since it restarted, Firefox (3.6) refuses to start properly, and crashes immediately.
I can see the white page popping up for a split second before getting a message saying that it crashed, and that I should send a report. I tried looking at the help FAQs on this website, about how I should be able to get a code for that specific crash's details. The problem is, however, that my last submitted report, according to my computer, is in june 2010, and we're currently in september 2010.
I still tried to refresh after the report has been completed, but nothing. So I figured I'd try to check in the details of that latest report, but 'lo and behold, it doesn't work, even though I followed the explanations provided on this website perfectly.
I did try to restart my computer again, and even download the latest Firefox version again, and reinstall it (even though that's what I had), but to no avail. It still does the same thing.
At the moment, I am using explorer, and would very much like to be able to use Firefox again, as I have most of my bookmarks in there and usually prefer to use Firefox, although I've been having other issues with it lately. I don't think they're related to the constant crashes, but if you insist on me sharing those, then I shall do so.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

When I close firefox with ctrl-alt-delete, I want to start over on Firefox, I usually do this when too many tabs and windows are open. However, Firefox always restores the tabs and windows I previously had. How can I stop that from happening?

This happens when FireFox is not responding, and I want to close firefox with ctrl-alt-delete. Too many tabs can make Firefox crash. That is why I want to use ctrl-alt-delete to close FireFox. I tried finding a way to disable this, but I found no option to.

Ending the Firefox program or process with the Windows Task Manager "looks like" a crash. The proper way to exit Firefox is click Firefox button > Exit (or File > Exit, if using the Menu Bar).
