After update 9.01 firefox crashed and I can't reinstall it ....

I recently updated firefox to 9.01 and after the update, whenever I start it it tells me that another copy of firefox is running, so I reinstalled it and after the reinstall the strangest thing happened the firefox icon has changed into a setup icon and whenever I click on it it tells me that I need to restart my computer, after the reboot nothing changes it's still stuck on the setup icon and it gives me the same message even when I select uninstall. How can I fix it ??

Firefox crashes and I can't open it. I have done everything you have listed

Firefox crash reporter comes up every time I try to start it. It won't open in safe mode. I deleted firefox per your instructions including in the programs files. I restarted computer and downloaded firefox to my computer desktop. I reinstalled and now I can't get it to open at all. The firefox crash reporter just comes up. I like fire fox better than internet explorer but if someone can't help me I will have to use it.

Hello, i dont know if you installed the windows update, but if you installed the Windows Update, is te cause of the Mozilla Firefox crash.
I restored my system from before the upgrade and magic! It was the mistake, after you reinstall from 0 my Mozilla Firefox in Safe Mode only opens, and now opens normally.
Srry for my english. I have Windows 7 64 bits and the update in 16-17/07/2013
I Waiting for the solution, because windows update install the updates automatically.

Thunderbird has crashed and I can't reinstall it - any ideas?

We aren't able to access our emails via Thunderbird on our home computer any more. The crash pane comes up straight away, and we can't even send details about that. It is just on this computer as I have my own email going in to my computer.

If and when I finally manage to open it, as soon as I click on a movie to watch, the message "itunes has stopped working" comes up.
Try the following user tip with that one:

# Question
Firefox crashes and when attempting to launch after the crash it won't launch; throwing an error msg that " js.3250 can't be found" - but same file is in Mozilla directory.
I must then download new 3.6.8 and lose all tabs and history.

I have a similar problem. Recently my FF8 has been crashing a lot. It regularly locks up an entire core of my PC and often just shuts down. It has just done it a moment ago and when it started back up it did the whole "this is embarrassing" thing and asked me if I wanted to reload my tabs. I deselected the one that I was trying to view as I suspected that it may have been the cause (unlikely; it was node4.co.uk) but anyway, let's skip it just in case. Click on the button to restore and up pops my homepage only. So all of my other tabs, which I was using for work incidentally, are gone.
This is not the first time this has happened on FF8. It happened a lot recently on FF6 I think it was (so hard to keep track now, Mozilla) and I switched to Chrome as a result, but it turns out that it crashes even more than FF6 did. FF7 was a vast improvement but FF8 is so unstable/unpredictable for me at the moment that I think I'd rather use IE9 than this. It's driving me mental, clearly! I wish I could kill the process manually and have it retry restoring tabs. Hey, there's an idea Mozilla; give us a menu item that allows us to restore the session to how it started to try again or at the very least get a list of the pages we were looking at. They don't show up in Recently Closed Windows and the Restore Previous Session is greyed out too. Gah! Help!

My iphone 5c crashed after updating to IOS 8.02 and now i don't have anything from the last 3 months. What do I do?

Don't worry about that. iPhone stuck in recovery mode always happens when you update the iOS on your iPhone. There are two ways to solve it.
First is is to put your iPhone in DFU mode.
Step 1. Turn off iPhone
Step 2. Hold down the Power and Home button.
Step 3. When you see the Apple logo, release the power button but continue holding the Home button down.
Step 4. Open iTunes and wait for it to tell you that it’s in restore mode.
If DFU mode can't solve the problem, I'm afraid the only solution is to try some 3rd party software, like iPhone data recovery or something like that. You may simply try the tutorial here: How to Fix iPhone that is Stuck in Recovery Mode.

Firefox crashed and after restarting, tabs i had open were gone and weren't in the history either. It didn't give me the option of restoring, how do i get them back?

Sorry , you probably can not get them back.
You may have bookmarked them, or have them as part of the History previously stored and still searchable, but unfortunately otherwise you are unlikely to get them back. Firefox does to a certain extent back up bookmarks automatically but not the history.
If you get problems with crashes see [[firefox crashes]]

after mozilla firefox crashed and a restart, the Firefox Developer Edition opend - how to open the normal firefox browser ?

See if this works for you.
Open up Tools > Options -> General and toggle the first preference - '''Allow Firefox Developer Edition and Firefox to run at the same time''' - to get back to your previous Aurora Profile. It will tell you to restart Firefox.
If there's a check-mark in the box for that pref it shows the Aurora Profile, if you remove that check-mark it shows the Developer Edition Profile.

After updated to latest Firefox, uninstalling sync and resyncing through my account, computer will not bring up tabs from synced computer.

I have followed all the steps to update to the latest version of Firefox, uninstall the old sync (which never worked anyway) and create a Firefox account to install the new sync. The Firefox sync tab shows computers as synced, but even after restarting the computer, it does not bring up browser tabs from the other computer. Both have all boxes checked on sync.
One computer has XP, my laptop has Win7.

N.B. - I am using the Windows service pack 2.
RAM - 2 GB

I had this same problem. Seems to be caused by the web developer tool bar FF extension (this started happening after a recent update to that extension). After disabling it, my FF is back to normal :)

When Firefox was automatically updated, it removed my yahoo toolbar and I can't reinstall it.

When Firefox was automatically updated to 29, it removed my yahoo toolbar and I can't reinstall it. I go through the motions of installing the toolbar and when I restart Firefox, the toolbar is there for a split second and then is deleted from the display. I have since removed the automatic update feature from Firefox and will only update if I deem it necessary and non-destructive. In the past your software has also removed the Social Fixer add-on. I am aware that Facebook does not like Social Fixer. Mozilla should remain neutral. You should not do Facebook's dirty work for them. I can do without Facebook and I can also do without Firefox.

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems?esab=a&s=troubleshooting&r=3&as=s#w_5-reinstall-firefox here].
<b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>
Please report back to see if this helped you!
Thank you.

Every time I place a bid on Ebay my firefox crashes and must be restarted.

Every time I place a bid on Ebay my firefox crashes and must be restarted. This is the only time this happens. It seems to be ok until I actually confirm the bid and within a second or two firefox crashes.

This is most likely caused by '''The Browser Highlighter''' add-on. Uninstall or disable this add-on from Tools -> Add-ons -> Extensions. You could also try finding an update for this extension.
See [[Uninstalling Extensions]] and https://support.mozilla.com/en-US/questions/682558
If that does not solve the problem:
Go to the address '''about:crashes''' and tell us your latest crash IDs. We can then look at the data specific to your crash and have a better idea of what is causing the problem.

Whenever IE tries to open, Firefox crashes, and cannot be reopened unti I restart the entire system.

Whenever I click on something that brings up IE (not the default!), Firefox crashes, and when I try to reopen it, a screen comes up that is supposed to let me reopen it, but it won't. I have to reboot the system in order to bring up Firefox again. Is there some trick to restarting Firefox after this crash?

My Laptop with Synced Firefox crashed and i had to do a fresh install, how can i retrieve all the synced data from the Mozilla Servers

I had set up Firefox sync on my Windows 7 Laptop which crashed and I had to reinstall windows. I used to be able to share content with my Firefox synced Android too. Is there a way i can retrieve the synced data from the Mozilla servers? I tried to set up sync on my new installation on a Mac 10.6 but when i click on Set-up Sync it asks me:
# Set-up new sync account (i already have one)
# I already have a sync account
When i select the second option it tells me to Add a device. I went in the "Sync Options" and tried the replace all data on this computer with my sync data, but nothing happened. When i try to connect from my Android it also asks me to add a device with the 3 boxes with letters in them.
So in both the cases it is asking me to "Add a device" but i cannot connect to my sync account in either case to sync data from there

Please search the forums. This has been covered here extensively.
