How do I uninstall/reinstall firefox?

I have been having a LOT of trouble with Firefox 5. I need to know how to uninstall it?

Hi marvinglen, sorry that you are having problems sorting-out Firefox.
I am not sure that ''Firefox Maintenance'' has much of an effect on Windows XP
* see [[What is the Mozilla Maintenance Service?]]
Uninstalling and reinstalling Firefox may be ineffective in removing an unwanted search engine app. It depends rather on what it is you have that you are now trying to remove. Some of these search helpers etc install globally within Windows and will need to be removed from the Windows control panel once you identify them.
Whatever you do I strongly suggest you do NOT use any option from Windows or Firefox that offers to remove personal settings, because that is likely to destroy settings including bookmarks and passwords. (If you see the ResetFirefox option also do not use that, without first taking note of what it removes - all your extensions, and some settings)
Once any rogue software is uninstalled you will need to reset any Firefox settings that have been messed up, but there is an add-on that is often capable of accomplishing that easily.
* see [[Remove a toolbar that has taken over your Firefox search or home page]]
** and consider use of https://addons.mozilla.org/en-US/firefox/addon/searchreset/
Please read the linked articles and post back with how you get on, and say specifically what it is you have found and are trying to remove.

How do I uninstall (& reinstall) Firefox when WinXP won't let me?

Using Win XP. I want to uninstall and reinstall Firefox because of an unwanted search engine app. I first uninstalled Firefox maintenance. Now XP won't let me uninstall Firefox. The control panel quickly flashes a screen but won't proceed with the uninstall. I tried instantiating maintenance from within the folder on my C drive but no response. I suspect by removing the "maintenance" app I've tied my own hands. Thanks for your help.

When I open firefox, normal tabs open, then several more that all show: Firefox can't find the file at /C:/Program Files (x86)/Mozilla Firefox/W¨'ÂÒ×žß¬¤ïžìWv¥YH´ªï]ã9v€Õ°pÎ%0C ï½Q2. I have uninstalled/reinstalled firefox with no help.

I can use the regular tabs, but new tabs will continue to open with strange things on them. One was marked as a Dangerous page by my anti-virus program (Trend Micro).

Don't what to say but WOW! downloaded and ran malwarebytes. It found a Trojan and something else. At the same time, my Trend Micro finally ran a scan and found 2 trojans and a cycbot, both associated with Adobe. Did the superantispyware program too, found a couple things. Uninstalled reinstalled firefox without any of the old personal settings, so NO add-ons at all. Opened in SAFE MODE and the error STILL persists. Computer does not want to shut-down and I find that I can do a few things then programs won't open anymore (such as my Trend Micro antivirus and even firefox.) I have no idea how any of this happened. I know a fair amount about computers and do NOT open links etc that I am not sure about. It was working fine while using in my truck yesterday. When I brought it in the house, it started doing all this. Just plain WEIRD! Any other ideas?

Even after uninstalling, reinstalling Firefox, the Firefox profile folder is empty, and I get the message "Firefox is still running and not responding close firefox...

Even after uninstalling, reinstalling Firefox, the Firefox profile folder is empty, and I get the message "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." I have followed all the directions I can find, on my computer and Firefox Support. Still, the same message comes up, and "firefox" is not shown in my Windows Task Manager.
What can I do?

Delete the profiles.ini file and let Firefox create a new default profile.

How do uninstall / reinstall Firefox without losing bookmarks / favorites

I recently upgraded Firefox to the 'optimized for Yahoo' version and have been experiencing slow starts and stalls. This happened once before when I upgraded Internet Explorer to an 'optimized for Yahoo' version. I was able to uninstall it and reinstalled the latest version from Microsoft, but I lost all my bookmarks / favorites in the process.

I reinstalled Firefox and the problem was solved. I have to say I am pretty disappointed with the support that I have got here. The helpers listed all the ways that I try to fix the problem but none of them worked. Also backing up data did not do anything. I lost all my history and saved password even though I followed the exact same steps as you gave me.
Seems like a lot of people are facing the youtube video problem, hope you guys can figure out how to fix it so that everyone is satisfied with using your service.
Thank you.

Since the "FREAK OpenSSL bug" in the Mac which has been making the news over the last couple of days doesn't apply to Firefox but does affect Safari and other Mac browsers, you might want to hold off uninstalling for a bit. But if you must, drag the Firefox application to the Trash. Next, locate your Firefox profile in /Users/your user name/Library/Application Support/Firefox/Profiles and drag that to the Trash too. Then empty the Trash.

After I uninstalled/reinstalled Firefox I lost my persona...How do I get it back.

It was a solid black background with a white scroll pattern and orange butterflies flapping every once in a while...animated. I cannot find it in the personas/skins any longer and wanted to know if I could get it back.

If it is online and you set up Find my iPod before you lost it go to the cloud and activate Find my iPod. You can also disable your iPod so a thief will not be able to use / access your stuff. If offline, you'll have to go looking for it like it was a lost wallet or purse. Report it lost / stolen to the police, and disconnect from this iPod, change all accounts and passwords to prevent a thief from accessing your stuff. The anti-activation with stop a thief if you had it active. Hope this helps, Good luck. Cheers.

Cannot uninstall, reinstall Firefox in Win7

Firefox has been running fine for years (currently 3.6) but then would not load, with error message FF already running. Reboot allowed FF to open, but subsequently after closing net traffic running at max DSL assigned rate. Ran AV scan--nothing, Ran system restore (twice) without effect.
Managed uninstall (after reboot) but could not successfully re-install any version of FF3. Saved all default-profile files to temp folder to copy back to new profile. This did not work. Last installation attempt FF setup did not create profile folder
When FF installed but not opening, there are two iterations of firefox.exe running as system processes. I would very much like to get this working--I will not use IE, and am not wild about Google Chrome.

You are definitely not alone. There are several threads with what appears to be this same, Catch-22 problem. Uninstall won't allow uninstallation for a clean reinstall because "a copy is running", but the alleged copy cannot be found. Ghosts. Voodoo. I checked the profile.ini file and it seems correct; this has been suggested but is not the answer, not for me anyway.
