Firefox minimizes itself and crashes - Windows 7

My Firefox 3.6.12 in my notebook when is minimized, for a little while, crashes itself and I can't maximize it. The program is shown on the Win7 taskbar. On the Windows task manager, FF appears like "working", but, if I press alt+tab or windows+tab, despite I can see, I cannot maximize that window.
My antivirus is up-to-date and in all tabs are websites that I use to visit frequently. There are no add-ons installed.
Obrigado antecipadamente a todos.
Abs,
Fernando

Fix by reverting to a pre-FF22 registry backup entry for:
HKEY_CURRENT_USER
Control Panel
Desktop
WindowsMetrics
You can't really modify the entries in regedit as they are hex data values. But this did (after a few hours) solve my problem.

Firefox stops responding and causes Windows to stop responding also

Sorry if this is vague; I just wrote a very, very detailed post on my issues but then the site decided that I didn't have permission to post it and erased everything.
My problem is that Firefox freezes and causes Windows to freeze for a while also. after a few minutes it goes away, but today I got the following error message:

I noticed the file "mswsock.dll" mentioned so I looked for issues with it. Apparently there are issues with malware and Firefox and that file. I have scanned and it found nothing, plus this issue has existed in three formats of my drive and windows re-installs (for other reasons, I didn't format and re-install just to make sure there was no malware) so I'm pretty sure there are no problems with malware.
I am running a Minecraft server and I have a static IP set up, but I've been doing this for three years without issues so I don't think that's the issue either.
I have tried disabling all plugins. Still crashes and crashes Windows with it.
I have run Memtest86+ and the windows memory tester. Not a memory issue.

Why does Firefox minimize itself upon launch. My husband is using Windows 8.1 with all recent updates.

I am trying to find a solution to my husband's computer problem. Upon launching the Firefox browser it will immediately minimize itself to the bottom of the screen, sometimes it takes a few minutes to do this, but it always happens. This has occurred with Firefox since we purchased the new Dell computer 64 bit running Windows 8. We have received all of the Windows 8.1 updates for it, hoping that it would correct itself. It seems to only affect Firefox, not any other browser. It has the most current version of Firefox, but it has been happening for all versions. He also uses the Google Chrome browser and it doesn't happen with it. I hope someone can help us with this as it is getting very annoying. He has had the new computer for several months now. If more information is needed about his computer, please ask.

What Firefox version is he using? If it's not current, you should update (for security, even if it doesn't fix this).
This could be something to do w/ Windows and / or some other software installed. You could try starting Windows in safe mode, then start firefox.
With this kind of problem, it's possible the Firefox program files got messed up. Ruling that out - by uninstalling - '''is faster than the addon troubleshooting''' steps below, so you may want to try uninstalling/ reinstalling first.
'''PLEASE... backup your existing profile''', before doing anything. It'll only take a few min & can save tons of headache. Search support.mozilla.org or Mozillazine.org (not the same folks) for "how to back up profile." It's easy & something you should do, anyway.
Uninstalling the Firefox program * shouldn't * affect your old profile, but you know how that goes.
Sometimes weird things like that happen due to addons used (& maybe less often, plugins).
Restart the browser in safe mode (search for: "mozillazine + safe mode", to see how).
Don't select "make the disabling of addons permanent;" just hit continue.
If it solves problem, you'll have to create another, new profile.
First, just try the clean profile w/ no addons, to make sure it doesn't have the same prob.
Start installing a couple of addons at a time, restarting as needed. Keep good notes.
See if any addons cause the problem. If so, narrow it down.
If you find one problem addon, don't assume the rest are OK, & install all the rest. More than one could be an issue.

Firefox keeps stalling and crashing; Adobe plug-in has been updated, but still says it's "out of date" on my add-in page...

I don't have any "out of the norm" add-ons...
I recently experienced Firefox continuously crashing whenever I try to attach a PDF to an e-mail in Yahoo (not a large file size - about 300kb). I checked my add-ons to see if there was an issue there, and noticed there was a message stating "Adobe Acrobat is known to be vulnerable and should be updated message", even though I thought I had already updated it.
I went ahead and re-downloaded anyhow... it successfully installs, and then I still get the same error message.
Furthermore, this issue was recently added on top of my Firefox already running slow and crashing... I often clear my cache and have tried running in safe-mode as well, although this doesn't allow me full capabilities...
The only thing that seems to be different is the issue with the Adobe Add-on and a recent Java update. Are there instabilities in these?
How do I fix the issue with Adobe? I need to be able to upload, download, and view PDFs...

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
[[Flash Plugin - Keep it up to date and troubleshoot problems]]
[[Flash 11.3 crashes]]
[[Flash 11.3 doesn't load video in Firefox]]

Firefox stops responding and crashes

My tablet is an Asus tf300t with an Android 4.02 OS. I really like what Firefox has to offer, but it is not working for me. I am even writing this on Chrome because Firefox would stop responding constantly.

[[Will Firefox work on my mobile device?]] is for Firefox for android and the is a requirement that ARMv7 should be compatible. However I would recommend filing a bug in bugzilla.mozilla.com with the about:support information if you can open it.
They may also ask you to provide this info if you have a device that can be accessed by the sdk [https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging]

Why did Firefox reset itself and delete all my bookmarks and favorites and how can i restore all my important information ? thank you .

Hello , this is what happen ! I turned on my Desktop from being in sleep mode and as it came on Firefox restored everything and made me lose all my settings and all my toolbar favorites and bookmarks , all my work was on here and all the compan y's I have dealt with in automobile restorations .
I tried a system restore from a date of a week ago but nothing came back , I really need someones help to restore my Favorites .I would also like the other version of firefox I feel lost with the version I have now and I dont like change .
Thank you .

Click on "Bookmarks" in your "Menu Bar".
Next click on "Show All Bookmarks"
The Library Dialog will open to you bookmarks. At the top of the dialog will be the option to "Import and Backup". Click "Import and Backup" scroll down to "Restore", when your hovers over "Restore" a list of backed up bookmarks should appear. If not, quite possibly Firefox has not been saving backups.
You can also manually save bookmark backups from the "Show All Bookmarks" portion of the Library by clicking "Import and Backup", and then "Backup..."
Also if you open another tab, you can type "about:config" in the address bar and press <ENTER>. This opens options not normally accessible. The first time it gives you a warning, you can disable the warning or leave it in place for the next the you open "about:config".
In the Search Bar type "bookmarks" and press <ENTER> . A list of attributes should narrow down to a few attributes about bookmarks. Look for "browser.bookmarks.max_backups" see what value is set... it should be set to "10". It sets the maximum number of automatic updates. To change it to a different value double click that attribute and increase/decrease just don't go overboard. Also you can delete older backups, just be careful. My bookmarks are listed with the newest ones first.

Firefox keeps freezing and crashing on 2 pc's

I have 2 pc's in the household which are using Windows 8.1 Pro 32bit and using firefox 37.0.2. They both currently have add-ons but firefox still crashing either if they are enabled or disabled. This happens then there is only 2 or 3 tabs open at one time. And sometimes Norton Toolbar doesn't work either. I have contacted Norton themselves and they say that their Toolbar is working fine as they had no reports for any customers. I think this is a bug in the browser which needs to be fixed. Mozilla needs to find out why this happens and fix it.

Several of the crashes are from flash player. You can try disabling flash protected mode:
go to "about:config" in the address bar and paste "dom.ipc.plugins.flash.disable-protected-mode" in the search box. Double-click on the result that appears to set it to true.

Window.event does not working in Firefox 4.0 and also window.event.ctrlKey ?

hi,
I'm using Microsoft virtual earth map 6.2 (bing Map) in my application.On map showing number of images.On Each image there is onClick event that select image if user press left mouse button while holding Ctrl key .For this I wrote java-script function where I'm using Window.event.button (To check mouse button) and window.event. ctrlKey(To check control key) But these both are not working in Firefox 4.0 ,the same is working in Firefox 3.6X version perfectly.
Thanks

The same problem is in Firefox 5.0 version too

I've tired everything to get firefox to open and crashes before it even opens! How do I get the crash ID?

I can't open firefox, and I don't know what the location bar is to get the crash ID. I was loading a page when it crashed, and have uninstalled and re-installed and checked for viruses and malware and nothing has helped.

Have a look at: http://kb.mozillazine.org/Breakpad#Location_of_crash_reports
Current common reasons for crashes are malware, and use of IDvault (I think comcast supplies IDvault, the software developer of it is WhiteSky, and a fix is due anytime now)

Firefox not responding and crashes when my netbook goes into sleep mode why is that

when i shut the lid on my net book and come back nand open it , put password in and when i click the firefox icon to go back to where i was at it says firefox is not rewsponding or firefox has crashed , why is that

Try running Firefox in [[Safe Mode]]. If it works properly in that configuration, then one of your add-ons is the culprit.

Well there are many issues with Outlook but the crashing does indicate a issue with Windows.

Firefox hangs up and crashes

Firefox freezes up constantly for 5-10 seconds on every page and function. I then close Firefox and when I try to re-open it, I receive an error message that tells me a session is already running and that it must be closed before starting a new session. I am then forced to restart my computer.

Firefox locks up and crashes when trying to print a PDF from a website?

I am using Firefox ver 3.6.13 Every time I try to print a PDF displayed on a web site Firefox locks up. If I have several tabs open all of them are locked. I have to use taskmanager to end the program and restart Firefox. To print the PDF's I have to save them then open them using Adobe reader and print that way.
I can vie the PDF within Firefox and all is good. It only locks up when I try to print. Printing any non pdf page I have no problem.

On my x64 Win 7 system, practically the whole system was frozen. After the "Print" button was pressed the dialog stating "Preparing" came up, but I had to use Cntrl+Shift+Esc to open task manager. Then I had to use keyboard arrows to select firefox.exe and Alt+E to end task and the space bar to confirm. Mouse would move, but not "click" anything. If I attempted to click anything, I had to Cntrl+Alt+Del to get to where I could "Log Off" and that forced firefox to quit.
I found my problem was an addon with improper settings. Internet Download Manager addon was loading with firefox, but in IDM's actual options, the check box to integrate IDM with Mozilla was NOT checked and the Advanced integration with browsers was also unchecked. I had been having issues with downloading from sites that do not allow 3rd party software to download, and it was taking forever holding down the key that prevented IDM from intercepting the download, so I changed the option in IDM, and I could still right click and select "download with IDM" from the context menu. Re-selecting the check box next to Mozilla fixed the problem

ITunes and Crashed Windows Computer

I have been using iTunes and my iPod with my Windows based computer (and LOVE IT). I need to wipe my hard drive clean due to a virus. When I reinstall iTunes, will my iPod replace all my music, videos and Podcasts back in the new iTunes? If not (because I've heard that it won't), what should I do? Is there a good method for "backing up" my iTunes?

Hello Rachet Jaw,
Thank you for the details of the issue you are experiencing with iTunes. I found a few articles I suggest for the issue you described.
If you are getting a white screen when accessing the iTunes Store, I recommend reviewing this article:
Apple software on Windows: May see performance issues and blank iTunes Store
http://support.apple.com/kb/TS4123
If you are still not able to access the store or are getting a different error than just a white screen, I recommend the following articles:
Can't connect to the iTunes Store

Thank you for using Apple Support Communities.
Best,

Firefox upgraded itself and now bookmarks from the last two years can only he "searched" but can't be seen in the list on the side bar or in the manager

I was running 3.5 and firefox did a little upgrade on it's own. Now I can't see any bookmarks I've added after 2009 in the bookmarks manager list or sidebar but if I search something I know I added it will show up with a date when I added it in 2010 or 2011 but I cant see these in the list without knowing what to search for. I only seem to have one "profile" I have tried restoring back to old bookmarks from the weekend with no success, and I even upgraded to 3.6 but no luck. Is there an addon or extension that could be blocking my view of the rest of my bookmarks?

Not sure about the middle click, I only used a two button mouse until recently, and maybe you could have subscribed differently or used some add-on.
Firefox 4 does not at present show the RSS icon in the location bar, but does have a customise option providing a button, or ass-ons can put one back in the location bar.
* https://addons.mozilla.org/en-US/firefox/addon/rss-icon/
* https://addons.mozilla.org/en-US/firefox/addon/rss-icon-in-awesombar/
The listings do still show icons differently if already viewed, and if links are displayed the read and unread ones may display differently. This depends partly on how the page you view is set-up by the feed provider.
My firefox is en-GB edition and default'' Latest Headlines'' http://fxfeeds.mozilla.com/en-GB/firefox/headlines.xml is the BBC news. The BBC site may have changed the option on that feed, clicking the option is to open individual tabs or all the tabs, there is no separate listing, or explicit news page option now, however left clicking the option ''Open "Latest Headlines"'' at the bottom of the RSS listing goes to the BBC news home http://www.bbc.co.uk/news/
Compare that with another feed from the BBC :
