After upgrading to FireFox 14 it keeps freezing as soon as it launches

I've never had much problems out of FireFox until the other day when it upgraded to the latest version (14.0.1) When it first opened up it was working.. but when you close the browser and want to open it up again.. it immediately freezes. Rebooting the PC does not even fix this. Firefox still locks up after a reboot. The only way to fix this problem is to uninstall FireFox and reinstall it. And even then, the same thing happens.. it works the first time.. and when you exit out of it completely, the next time you want to open FireFox, it will immediately freeze and the only way out is Ctrl ALT DELETE.
Can someone help me get FireFox to work again please?

Hi,
You can consider the [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems Reset Firefox] feature via '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information'''.
(To revert to the previous profile, close the new profile, start Firefox and choose the '''*.default''' profile. While the [https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles Profile Manager] is open, you can also delete the newly reset profile (the one containing random numbers)).

If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of Firefox and related files in all the different configuration areas/modules of the security software. Instead create new allow/trusted rules for Firefox + its related processes. Even otherwise the security software may also ask again when Firefox is started and you can try to allow/trust at that time. Please see [https://support.mozilla.org/en-US/kb/Firewalls this].

After upgrading to Firefox 36.0.4, it automatically installed noscript

After upgrading to Firefox 36.0.4, it removes all my existing add-on extension.
In addition, "noscript" was automatically installed and there is no way to remove it.
The "noscript" add-on does not show up in any of the add-on extension for me to disable/remove it.
I even tried adding noscript from the add-on so that the noscript add-on shows up in the
firefox extension page so that I could remove it but that does not remove the
original noscript that comes with Firefox 36.0.4
Hopefully there is a way for user to remove this and it is not part of Firefox 36.0.4.
At least allow user the options of using it or remove it.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then also create a new profile.

After upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues

after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

I'm having a potpourri/Hat-Trick of issues after upgrading to Firefox 7.0.1

The only reason I'm asking is because the three new issues occurred immediately after upgrading from the last install of Firefox to the newest release, Firefox 7.0.1
The first: for some reason I have to go to about:config to reset the "Close Tabs" part from 3 to the default 1 setting...which is having a Close Tab "X" on the tab. It means I have to right-click and select the bottom option on the drop down menu to close tabs I'm through with using.
The second: Most of the time Google Videos will not function on 3rd party web sites (Like "Documentary Storm"). I have to redirect to the Google Video webpage to watch Google featured documentaries that have been embedded in some documentary sites.
There are now more frequent error messages of "Not Responding" on websites...the screen locks up for a few seconds before going backwards or forwards (On "The Chive", "The Brigade", and many other picture or video oriented websites.) The scroll bar on the right side of the screen is also locking up which means the "Not Responding" error message is popping up for this also.
All of these are different from each other and at first thought would be issues I need to take up with tech support for the different programs I use. That is my next step, but I was very curious if anybody else was having similiar problems after upgrading to Firefox 7.0.1.
I'm not sure if a couple things might be set off by incompatible Addons. None of the symptoms jive with known incompatibility problems with 7.0.1. and with none of my Addons either. It was just very coincidental things went awry in 3 different areas that had worked 10 minutes previous to the upgrade.
Any ideas or similarity with other folk's upgrade issues?
Thanks tons for any advice given! Hoping it's something ridiculously easy. : /
Oh yeah...all other programs are up to date. Freakishly OCD about keeping current with programs.

Thank you for describing the problems so well. I also have been going nuts trying to restore my Itunes Library to its original (or acceptable) condition. I have a 5th gen 30G Video with about 4250 songs on it. After downloading 7 I found that every song in my Library had been dulplicated or triplicated. Then, a day latr, when I had downloaded album art, I discovered that every other song in any album I had downloaded (from Itunes or my own cd)prior to perhaps version 5 or version 6 could not be found. Luckily, I had an generation 4 Ipod with the original Library and I was able to download that to my external harddrive. I have spending pointless, arduous hours pointing Itunes to the correct file. Its faster to re-download the CD. Of course, I can't do that for any music I had bought from Itunes directly. Its weird because the name of the song is in Itunes, just the file can't be found. And why every other file? When I go into earlier (6 and before)Itunes Libraries, the music files are missing from them. Where did they go? When I try to sync my Ipod with Itunes, it takes forever because Itunes is searching for the missing files. I have tried to ask Apple support directly but I have gotten no response. Very, very frustrating! Any headway with your problems? Lisa

After upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?

after upgrade to mavericks: time machine keeps asking for my back up disk and won't open unless i plug in the disk. any solutions?
before the upgrade, i could open time machine without the need for having the back up disk plugged in.

Ok. I got it to work, sort of....
As I mentioned before I tried the "disk password" and the "Time capsule Password" options to see if I can start the back up again or start a new backup. Neither worked. So I tried the firmware down grade, but like you said that did not work. I then decided to try the "Account password" option and I have never used this option before becasue it states that if there is data on the drive it would not be acessable after creating an account. Since I wiped out the disk that was nno problem. When I created the new account and choose the drive it asked for the user name and password. I entered the info for the new account I just created(FYI this has nothing to do with your login username and password), bingo! It worked!
Now I have two partitions on the TC disk. The old one and now the new account. I am guessing this is to be used if I have multiple computers, which I don't.
I any case, I am going to wipe out everything again and try again to do a backup the way I had it before.

Can't get past home page of instructables after upgrading to firefox 13

I can load the home page, but if i click on anything past it, it acts like it continually loads, nothing comes up on the page, it sticks at "Transferring data from www.instructables.com..." or "Read www.instructables.com" it seems to only have happened after upgrading to firefox 13. I have an old version of firefox aurora that came with the tor browser suite and tried instructables on there. worked perfect, and i was going to instructables on a regular basis before the update, so it's gotta be from the update right? what can i do to fix it?
P.S. It's not just the specific URL under "URL of affected site" because none of the pages will load after the home page.

did that solve the issue? i still believe it has more likely to do something with faulty cache (maybe the restart of the browser really triggered it );
if it was an issue with dns prefetching it would be rather strage since you already were on the domain instructables.com & wouldn't have had to resolve the domain for the subsites again. and since the server, your isp or your local hardware might not support ipv6 fully yet, it can always cause some glitches too...

After upgrading to FireFox 7 on Windows 7 64-bit Home Premium, I can't load the games in Google Plus.

Long time user of Firefox, but recently I've been having problem. After upgrading to FireFox 7 on my laptop with Windows 7 Home Premium (64-bit), none of the game in Google+ will load. One game pop up a screen saying cookie acceptance is disabled even though it is enabled. One game just won't load at all, but will not give any error message. I installed Adobe Flash as well, still not working. Previous version of firefox works fine without a problem. Also, I recently reinstall Windows and fresh copy of Firefox 7, still the same problem.

Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
* Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
"Remove Cookies" from sites causing problems:
* Tools > Options > Privacy > Cookies: "Show Cookies"
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

What can I do about this: After upgrading to firefox 6, I get this error. TypeError: Components.classes[cid] is undefined???

What can I do about this:
After upgrading to firefox 6, I get this error.
When I click to open Firefox, A box open with the following error:
JAVASCRIPT Application
TypeError: Components.classes[cid] is undefined?
After I click close on the box, then Firefox will start. I really just want to get the error fixed so that when I want firefox open, I don't have to see this box anymore.

You need to figure out which add-on is causing that error and disable it until the developer of that add-on fixes it. There may be an error message about that in the Error Console, accessed through the Web Developer menu item or through {Ctrl + Shft + J}.

Cannot view OWA email - after upgrade to Firefox 5.0, Outlook Web Access displays ASCII characters (garbage) in message body. Same issue with multiple servers.

Email body of HTML or RTF messages are rendered in ASCII characters after upgrading to Firefox 5 when viewing email in MS Outlook Web Access (OWA) light from MS Exchange 2007 servers. Issue is repeatable with two entirely different Exchange systems.
Text email renders OK. Work around is to forward email (in use MS-IE).

You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf
70sareobfu0.cf
70sareoem.cf
70sarespoof.cf
70sarestocks.cf
70sareunsub.cf
72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck!

After upgrade to Firefox 6, certain sites can no longer be loaded.

After upgrading from Firefox 5 to FF 6, certain sites will no longer load. These sites both use Typepad and that seems to be where FF6 hangs. Have not had this problem with FF5. Tried clearing cache, deleting bookmarks (to sites that won't load), and typing in address. That doesn't help. Sometimes, the sites load partly (i.e. with only words, no images); other times, load after a long time (several minutes); most often will not load at all.

I've only one hint to you, cause I've mot on Mac-Server.
With 10.7 Apple have switched from Samba (maybe due to licence problems with GPL based stuff) to a own protocol called "XSMB"
This had caused problems with some NAS systems too.
Eventually someone have a glue to solve that, as several users have problems with SMB shares since that.

Windows media player stop working after upgraded from firefox 6.02 to Firefox 7.01 yesterday.

windows media player stop working after upgraded from Firefox 6.02 to Firefox 7.01 yesterday.
the plugin for win media player is already installed and working fine in FF 6.02 before upgrade. i have Google this issue without any result so far. so i reinstalled the old version 6.02, until fix is found.
anyone has the similar issue with Firefox 7.01 in Win 7 32 bit ?

The issue was not with FF 7.01. VLC player version 1.11.1 is conflicting with windows media player when FF 7.01 tries to play media files! Which was not happening before in FF 6.02.
VLC and plugin media player need to be uninstalled first, then uninstalled FF 6.02. Install FF 7.01 and then win plugin media player again.

Bookmarks don't work after upgrading to Firefox 5.0

My bookmarks don't work after upgrading to Firefox 5.o. Please help! The icons no longer show and instead there is a blank paper with the top right corner folded. I can't even bookmark new pages! I tried reinstalling the program and that didn't work. Please help!

Your bookmarks file may be corrupt. Navigate to /[UserName]/AppData/Local/Mozilla/Firefox/Profiles/[profile_name]. Either rename places.sqlite to places.sqlite.corrupt (or whatever) in case this isn't the problem, or delete places.sqlite. Start/Restart Firefox. The icons for sites that have a favicon should return after you visit each site.
