How to uninstall Firefox 4.0.1 still on my computer

It is taking up space on my computer but I have updated to Firefox 6.0.1 or whatever the newest version is.. I am confused on how to uninstall can you please help with this Thanks

As a workaround, you could open PDFs in the Adobe Reader application rather than in the plugin. To try this:
In Adobe Reader, open Edit > Preferences
In the left column, choose Internet
In the right pane, ''uncheck'' "Display PDF in browser"
If you have the full version of Acrobat, make the same change there.

How to uninstall Firefox when it still says it's running

I have checked all the troubleshooting suggestions to get Firefox running correctly again. Finally decided I just need to completely remove it and download a fresh copy.
Problem is when I try to uninstall the program it tells me "Firefox must be closed to proceed with the uninstall, please close firefox to continue."
I have, it's not showing up in any of the processes that are running. Any advice?

Hello,
Upgrate to latest version....beta 34.0.5...
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 [https://www.mozilla.org mozilla.org] (or choose the download for your operating system and language from [https://www.mozilla.org/firefox/all/ this page]) and save the setup file to your computer.
#After the download finishes, close all Firefox windows (or open the Firefox menu [[Image:New Fx Menu]] and click the close button [[Image:Close 29]]).
#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 [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox|here]].
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your [[Profiles|Firefox profile]] data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See [[Back up and restore information in Firefox profiles]]. 
Please report back to say if this helped you!
Thank you.

[SOLVED]How to uninstall "Firefox Scrollbar Fix" in KDE?

After I installed the Firefox scrollbar fix, on websites with White over Black text, I can barely read it. I have a dark color theme, and it hasn't been a problem until I installed this fix. Please tell me, how do I uninstall it? It's really getting on my nerves.

How to uninstall firefox 4, MouseControl Add-on? I got to the add-on managing page, but the 'remove' , 'disable', or 'option' button doesn't respond to mouse clicking on it

While on Firefox browser, the MouseControl add-on prevented me to open my yahoo mail and access buttons and tabs and keyboard functions on some pages. When clicked on certain button/box, nothing is recognized. I can't disable or remove this add-on, because I can't click on the 'disable' nor 'remove' buttons; the command is not recognized! I decided to uninstall Firefox 4. When re-install Firefox 4, the MouseControl Add-on was not removed and all the problems are still there.

Hi so sorry about this problem. There was a warning (for unexpected behavior) when changing the button configuration but I agree that's not an excuse. Please uninstall it by restarting your browser in safe mode. Use the keyboard press Alt+H, this opens the help menu, use your arrow keys to move down to "Restart with addons disabled", then uninstall it from there, also please check out v1.5, this version resolves this stuck mouse issue.
Again very sorry about this.

How to Uninstall firefox 3.6.25 with Firefox 25.01 is installed?

I found the 3.6.25 version under the startup menu and cannot figure out how to uninstall it. it is not in the control panel add/remove, only one from add/remove is version 25 and I dont want that removed. i have even gone into regedit but no uninstall was found for that version which makes me more uncomfortable. I need help, Thanks!
OS: Windows XP 64bit

Is that really a Firefox 3.6.25 version or is only the user agent corrupted?
You can check the real version in the Help > About window.

Where is the webpage that tells you how to uninstall Firefox on the Mac?

I installed FF 4 on my Mac just to discover that I could not run Google Gears on it. So I need to uninstall FF4 and install FF 3.6. I searched for a page and to tell me how to do this an found one at http://support.mozilla.com/en-US/kb/Uninstalling%20Firefox. After doing part of the process and removing FF4 but not the profile I went back to this page in Safari. But not the instructions change and it is telling me how to uninstall on a PC. So how do I find the Mac uninstall page when FF is not installed on my Mac.

It goes by you useragent to tey and serve a page based on it. To get another OS or Firefox version just look at the right of articles where it says '''Help with:''' and click on the OS and Firefox to change accordingly.
I use Firefox on Linux so it serves me a page for Linux users yet I may want to sometimes change it for Windows when helping Windows users.

I updated StumbleUpon which offered a tool bar. Since then I get no URL line, including everything else normally on that line. I have uninstalled Firefox and reinstalled and still get the same. What can I do to correct this without doing a system restore

I recently updated the add-on StumbleUpon which offered a tool bar. Since then I do not get the line which has the URL space as well as other functions. I am now forced to use IE. I have uninstalled Firefox and reinstalled but get the same startup page. What else can I do short of using system restore to a prior date?
== This happened ==
Every time Firefox opened
== when I last updated add-ons.

This issue can be caused by the Yahoo! Toolbar extension

How to uninstall Firefox. There apears to be no uninstall program for Mozillla Firefox on my computer. I've tried everything suggested and nothing works.

I have done everything your web site says to do to uninstall Firefox. Nothing works. Windows message says no Mozilla Firefox uninstall program on my computer. Do I need a special download from you to uninstall?

Struggling with this issue, I'm surprised by the absence of an uninstaller.
Have tried all the suggested steps and nothing worked. It is frustrating.
My reaction is "never again". Once I get this program off my system, I'll
stay away from Mozilla.

I want an address bar so i dont have to do searches to get to a website have looked at the help pages and cant find out how to get one i thought it would be automatic so why dont i have one

''Missing Location bar''
Part of the problem in looking for solutions is that Firefox calls it the Location bar.
Use the "Alt" key to show menus, then View > Toolbars > (check) Location bar
See item #2 in restoring Menu bar and '''other''' toolbars
You can make Firefox 4.0.1 and '''Firefox 5.0''' look like Firefox 3.6.17, see numbered items 1-10 in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 4.0 look like 3.6)]

Mozilla/Firefox 4 will not install on my computer and I cannot uninstall any old Mozilla/Firefox programs and files still on my computer.

Firefox won't load onto my computer. I have Windows 7, and each time I try to run the program to install it, it tells me I have another version still waiting to be installed that requires my computer to reboot. When I check "yes" to reboot, my computer reboots but still no Firefox. When I try to uninstall the the old Mozilla program from my Control Panels, there is no Mozilla files or programs listed not in my list of programs but when I go directly to the Windows File on the C: Drive, there's a Mozilla program file there. WHen I go into that file check, I attempt to open the uninstall program. I get an error message that says something to the effect of: "the version Mozilla on this computer is not compatable with my OS." Something about it being and 86bit program. My Firefox 3.6 worked fine 2 days ago. What's wrong???

Ok, lets do a couple of steps here first:
To make sure your windows isn't corrupted because of the power outage, let's run chkdsk.
Click on My Computer, then right click your C: Drive (if you have other hard drives, you will want to run this on them as well). Then, click Properties. Inside that window, go to the Tools tab. Inside that tab, open up the "Check Now" button. That will open a smaller window. Select the checkbox to "Automatically fix file system errors", then hit Start. You will probably receive an error asking if you want to schedule the disk check, click Yes, then restart your computer.
Read [http://support.microsoft.com/kb/315265 http://support.microsoft.com/kb/315265] for more information.
After running the chkdsk, then please go to [http://www.getfirefox.com www.getfirefox.com], and download a fresh version of Firefox. I'm assuming you are using Internet Explorer to download Firefox. Instead of hitting Run, let's try hitting save. Remember where it saves the installer file on your computer.
After the download has finished, double-click and run the Firefox install. Once it is finished, try to start Firefox up. Let me know how it goes!

How to uninstall Firefox if Add/Remove programs won't work?

My Firefox is completely unresponsive. I can't get a browser or anything. I just grabbed the application folder and threw it in the trash, because the add/remove program function did nothing. I also cannot download the newest version of Firefox. It tries, but then says, "Your download was interrupted".
How can I make sure I've removed ALL of the old Firefox and what can I do to download the new one?

How to uninstall firefox tv

When I open Firefox or open a new tab, I get Firefox TV! http://www.outfox.tv/?referid=130
How do I get rid of it! The Firefox TV "Uninstall does nothing and there is no application under Control Panel for removing applications. It refers you to a uninstaller link which Norton blocks! http://www.outfox.tv/OutfoxTVRemover.exe
I really, really really hate this POS!
Any help is much appreciated.

There are other things that need your attention.
Your System Details list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts.
The user.js file is only present if you or other software has created this file and normally it wouldn't be there.
You can check its content with a plain text editor (right-click: Open with) if you didn't create this file yourself.
The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.
Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.
You can use this button to go to the currently used Firefox profile folder:

How to uninstall Firefox App that crashes Asus everytime it runs

For the last versions of Firefox on Android, Firefox crashes my Asus TF300T app everytime it is run. Either being run through clicking on a link (as it was set as the default browser), or if I manually run the app. The app also crashes my tablet when I try to uinstall it. This is the only app on my tablet that does this and I now run Chrome with no problem. As of right now, I have no way of removing the Firefox App without reimaging my Android. Is there another way to remove this app?

If you are unable to remove Firefox for some reason, you can at least change your default browser. Scroll down in Apps/Firefox and in the Launch by Default section tap the Clear defaults button. The next time you tap a hyperlink, Android should prompt you to choose an application.

Adobe After Effects CS6 - how to uninstall/reinstall or transfer license to a new computer

My old computer has crashed, and so I built a new one recently. I have been installing all the applications for it, downloading files, so on and so forth. I recently insterted one of the hardrives from my old computer, and was able to see the files I had from my old computer. All of my adobe applications are on there, and I can see them, however; I cannot use them, which is okay, since most of them were free applications that I could download from the website. But Adobe After Effects CS6, which is the application I really need, does not open it; instead, it reads: "Configuration Error: Please uninstall and reinstall the product. Error: 16". I bought the CD for After Effects last summer, but I cannot find it anywhere. I heard you don't need the CD to transfer the license to a new computer, but I can't figure out how to do this.
Any help would be greatly appreciated, since after building my computer, I have absolutely no funds nor interest to buy another After Effects CD.
Thanks,
John W. King
