You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

You can also try to disable OMTC and leave hardware acceleration in Firefox enabled.
*about:config page: layers.offmainthreadcomposition.enabled = false
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

I updated Firefox and now it will not open at all. The hourglass shows that it's working but then nothing. I went to add/remove and removed mozilla and reinstalled it and still the same thing. It worked fine before I updated.

I updated Firefox and now it will not open at all. The hourglass shows that it's working but then nothing. I went to add/remove and removed mozilla and reinstalled it and still the same thing. It worked fine before I updated. Now I can't even remove the program at all. Why is this happening?

Start Firefox in [[Safe Mode]] 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).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.com/kb/Safe+Mode
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

I am trying to update my iPod touches and keep getting an error message saying iTunes could not back up my iPod because a session could not be started. I have followed all trouble shooting advice found on the apple website, unplugged and replugged the device, restarted my computer, etc. Any suggestions would be much appreciated. Thanks

Hey KarlaOrtega23,
Thanks for the question. I understand that you are experiencing issues with iTunes on your PC. I also understand that you have already uninstalled iTunes and the problem persists. While you have already attempted these steps, there are some specific details outlined in the following resource that may help to lead to a resolution. For example, make sure that you have uninstalled all components of iTunes in the order listed. Uninstalling the components in a different order, or only uninstalling some of these may have unintended affects:
iTunes 11.1.4 for Windows: Unable to install or open

Thanks,

Mapquest sign in box does not appear in Firefox but does in Internet Explorer. Why? Have disabled add ons but no luck.

The sign in box does not show up on Mapquest when I use Firefox. If I use Internet Explorer, the sign in box appears. I disabled the Firefox add-ons thinking there might be a conflict but no luck. Mapquest support is at a dead end, too, especially with it working in IE but not in Firefox. Suggestions?

Can you post a link to that login page or is this a pop-up window?

I have 7.0.1 installed. Everytime I open something like Gmail or Google Plus, it says the version of Firefox is outdated and asks to upgrade to the new version. I uninstalled the whole thing and started with a fresh install and still the same problem.

Even this website thinks I have Firefox 3.2.

Your UserAgent string in Firefox is messed up by another program that you installed, it shows that you have Firefox 3.5.3.
[http://en.wikipedia.org/wiki/User_Agent]
type '''about:config''' in the URL bar and hit Enter 
''If you see the warning, you can confirm that you want to access that page.'' 
Filter = '''general.useragent.extra.firefox''' 
Right-click that preference and select '''Reset''' 
Then restart Firefox

Have used Firefox for a long time and now it will not boot up and I get message saying cannot initialize security component. Have uninstalled and re-installed Yahoo optimized 5 version and still the same.

The only thing I have done different in the past few days is to install trial version of Bitdefender Total Security and I used the PC tune-up feature for PC clean-up and registry cleaner. That seems to be the point I could not loner use Firefox.

I have Firefox 3.6.6, and now that Firefox 4.0 is available, it crashes constantly. Sometimes less than 5 minutes after I open it. I have a Mac 10.4.11, so Firefox 4.0 isn't an option for me. When I asked Ff to check my plug-ins it said there was an error and to check back later. Twice.
Because I didn't have any (any) problems with my Ff before the upgrade became available, I am forced to question if Ff has done something to make the earlier version crash so you'll upgrade, but I can't afford to upgrade my Mac right now.
In the meantime, I do need a browser that works! I dislike Safari, Chrome is also not available on Mac 10.4.11, and Explorer is just plain not available on Mac.
Do you have any suggestions on how to fix my Firefox 3.6.6?

Had to disabled add ons but it seems to have caused YouTube to insist I upgrade Adobe Flash Player. Did so several times, rebooted and reinstalled Foxfire but still can't play any videos on YouTube with Firefox. Chrome works fine. Please fix.

Youtube on Firefox won't recognize Adobe Flash Player.

What is your current Flash Player version: http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html ?
What is your display adapter, driver version & date? See http://forums.adobe.com/thread/945765

Tabs will not load sometimes unless I move the cursor or hold down an arrow button. If I close all tabs and reopen, it will work properly for a while then start doing the same thing. I've tried disabling add-ons but it does not help.

I've had this problem with earlier versions of Firefox. I am currently running the latest version which I think is 6.0.1. Firefox also is not responding a lot since the latest version update. I'm running Windows 7 Home Premium 64 bit.

I finally resolved my problem after spending way too much time on it. I simply handed my 160GB iPod to my husband to put his fav Stones & Beatles songs on and I went back to my 80GB Microsoft Zune which has never disappointed me.
After spending so much time trying to figure this out I did finally take it back to Apple Store who performed a diagnostic and found there was a problem with the device. They replaced it with a refurbished one which has similar issues. All I wanted to do was listen to my music. Was that too much to ask? So I am happy to be free of this problematic device. No more Apple for me!!

I'm having some problems wiht Firefox, for example; Youtube isn't loading right, Facebook won't let me send messages, search up people, and this website i made wont load right also. I've re-installed and updated it but still the same problems. Any help?

Because I know enough to be dangerous... I was trying to extend the two outside columns down.... Instead of just using faux columns which I have fixed since I posted the question.
The other link problem is the left sidebar links. When you go to the event photos page I have a repeat of the sidebar links that are on the newsletter page. I used named anchors on the newsletter page to link to the particular article. From the Event Photos page the links look like this:
<a href="1112Visions_Iss1.html/#puzzle" target="_self">[Puzzle]</a>
The problem I am having is that some of these go to the newsletter page and the anchor and some do not (I get an error message saying it can't find the page). To add to the problem is that when we choose say the President's Message, when it goes to the newsletter page and the correct anchor, the newsletter page is missing all the links to the graphics... the photos are missing the graphic for the faux columns is missing. It makes no sense. When I preview the newsletter page from Dreamweaver everything shows up fine.
I do not know if all of this is being caused because I haven't posted this stuff to the site or what. I've tried re-booting both the browser and Dreamweaver, dumping the cache and still the same nonsense.
Got any ideas?

Firefox wont start "XPCOM" message pops up, need my user and passwords!!??

My window 7 wasn't starting up properly so I did a system restore and now firefox wont start a message pops up stating "XPCOM" and I googled it and everything is telling to reinstall Firefox. I don't wont to reinstall it just yet because I need my passwords and username back. I cant find a solution on the forums either, or if there is I haven't found it or I simply didn't understood the solution itself. Please get back to me asap
thank you!

This usually happens because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop https://www.mozilla.org/en-US/firefox/all/
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*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.
*http://kb.mozillazine.org/Uninstalling_Firefox
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.

Firefox wont start after overnight XP patch installation

Overnight XP installed a patch and rebooted my PC. This morning I can't get Friefox to start. I looked for the xpicleanup.dat file using the instructions here (search hidden files etc) but search ends without locating the file. Does anyone know where Firefox parks this file normally? If not I am not sure what to do next?

* Start Firefox in Safe Mode by Holding down the SHIFT key while starting Firefox
* As an alternative method, select "Start -> Run" and enter one of the following in the Windows Run box:
** firefox -safe-mode
** "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
-> Firefox Safe Mode window will appear -> DON'T SELECT ANY OPTIONS, just click '''Continue in Safe Mode'''
-> Troubleshooting extensions and themes
* https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
Check and tell if its working.
