Firefox 37.0.2 will not install

Task manager shows that 7z Setup SFX (32 bit) is running in the background, but the application will not install.

Try this:
*Download the Firefox installer and save the file to the desktop<br>https://www.mozilla.org/en-US/firefox/all/
*Start the installation with a double-click on the desktop icon
You may have to disable your security software temporarily or boot the computer in Windows Safe Mode with network support (press F8 on the boot screen)if you keep having problems.

Firefox 13 and 14 will not install properly on my windows 7 starter. Also I cannot get the Scrapbook addon to work. Can you tell me why ?

I have tried to install Firefox 13 and 14 on my netbook, running a Windows 7 starter OS. The installation begins to go smoothly from the setup.exe file; but after the installation seems complete, and I press the 'Open Firefox' button the firefox programme can be seen to start opening because it accumulates about 50mb of private bytes RAM on the windows task manager or on the 'process explorer' utility program by sysinternals. '''However the firefox screen/window never opens up and so firefox does not seem to be properly installed.'''' Also I have had problems with getting the Scrapbook" addon to install properly. I have another computer, a laptop, running XP Home, and I can get the Firefox 13 or 14 to install but it is on this other computer that I cannot get the 'Scrapook' addon to install properly; There is no notice on the Addon page saying the 'Scrapbook' addon does not work on Firefox 13 or 14, and the addon does install, but not properly, so it does not work.
I have the old Firefox setup.exe files, and so I have managed to install an old version, firefox 3 or 4, on an external hard drive. I have successfully got this old firefox to work on the XP Home laptop from an external hard drive, and can successfully use the 'Scrapbook' addon in this way.
I cannot understand why I have problems with Firefox 13 or 14. I think I first noticed the problem about 'Scrapbook' with Firefox 12.

It seems your Mozilla installation is broken. Try the following steps to fully uninstall Mozilla Firefox:
1. Uninstall Firefox as you would normally do.
2. Open a command prompt as administrator.
3. By using the cd and rd command, remove Firefox AppData and Roaming folders, for example:
C:\Users\USERNAME> cd AppData
C:\Users\USERNAME\AppData> cd Local
C:\Users\USERNAME\AppData\Local> cd Mozilla
C:\Users\USERNAME\AppData\Local\Mozilla> rd /s Firefox
C:\Users\USERNAME\AppData\Local\Mozilla\*.* - Are you sure? (y/n) y
C:\Users\USERNAME\AppData\Local\Mozilla> cd ..
C:\Users\USERNAME\AppData\Local> cd ..
C:\Users\USERNAME\AppData\> cd Roaming
C:\Users\USERNAME\AppData\Roaming> cd Mozilla
C:\Users\USERNAME\AppData\Roaming\Mozilla> rd /s Firefox
C:\Users\USERNAME\AppData\Roaming\Mozilla\*.* - Are you sure (y/n) y
C:\Users\USERNAME\AppData\Roaming\Mozilla > exit
Remember to press Enter each time.
4. After that, open a hard disk clean-up tool (such as CCleaner or Windows built-in) and remove all temporary files from your computer.
5. Restart your computer. Download '''again''' the Firefox package from [http://www.mozilla.org/es-ES/download/?product=firefox-14.0.1&os=win&lang=es-ES Mozilla official servers] and try to install Firefox. If the problem persists maybe your computer has a problem or is infected with viruses.
About the Scrapbook add-on, I could get it to work. It has no icon when docked to the toolbar, but you can anyway open it. Right-click a button on the toolbar, click Customize... find the Scrapbook icon, drag it to the bookmarks bar so you can see the icon and click on it to open it. Whenever you need to save a page, right-click that page and choose Save page.

Download of firefox and adobe flash will not install file corrupt message

cannot install firefox or adobe flash get file corrupt message:
cannot play videos

Try installing from the Offline Installer. It may be a temporary folder permissions error, so this may fix it. Here is a link to try to download from:
http://download.macromedia.com/pub/flashplayer/current/support/install_flash_player.exe
If that doesn't work, try this one: http://www.filehippo.com/download_flashplayer_firefox/
Let me know if this works!

Firefox will not install. I keep getting a message that I have to restart my computer in order for updates to a previous version can be installed.

Every time I restart the computer and try to install firefox the same message keeps appearing. I attempted to uninstall the earlier version of firefox using "programs and features" in windows but the same message came up and thus I was unable to uninstall using that method. I have used a third party uninstall program which appeared to delete all traces of firefox including registry entries but I still have the same problem.
I am now in the position of not being able to load any version of firefox. HELP

Same problem here. I installed version 4.0, then removed it and tried to install 3.6. Now no version Firefox will not install. I keep getting a message that I have to restart my computer in order for updates to a previous version can be installed.

Firefox home will not install on my iPhone

Firefox Home shows up as "purchased" in my apps listings for/on my iPhone 3G but will not install on my phone either through iTunes syncing or through my iPhone apps application. What is wrong? All other apps install, deinstalled, and reinstall fine. The app used to work fine, but one day I noticed it was missing from my phone and now it won't reload.

Strange - You can't even install it directly on the phone from the App Store. Have a look [http://support.apple.com/kb/TS1702 this Apple troubleshooting article]. Beyond that, Apple would probably be better equipped to help you.
Let us know if you have any new information.

Why can I not install adobe flash, I get a message saying it will not install while firefox is runing

When I try to download adobe flash player everything goes fine and the download finishes. When asked to install I get a message that says it will not install while an application is running. Which is Mozilla Firefox

Adobe Shockwave Flash needs to install plugins for Firefox, and Flash needs to do that with Firefox closed. So close Firefox and run the Flash installer.

Adobe Flash Upgrade will not install after Firefox upgrade to 3.6.7

I upgraded to Firefox 3.6.7. After the upgrade I got a message that I needed to upgrade Adobe Flash due to security vulnerabilities. The Flash upgrade will not install. It simply sits and never installs no matter how long I wait.
== This happened ==
Just once or twice

Thanks for your response. I have previously reviewed this. The only potential problem it seems to resolve is having 2 versions of Shockwave installed. I only have one. The only thing I can think of to do is just uninstall the one version and see if it will trigger an installation. When I go to the Flash install site, I agree to the terms and get the next screen that says download will start. I never get a message asking if it's ok to run or anything. No matter where I look for a download for Flash I wind up at the same place with the same problem. Any suggestions would be most appreciated.
Thanks

Updater will not install updates from Firefox

Windows XP, click on Help, About Firefox, Check for updates. They download. Then I click on Apply update. A window appears saying "updater.exe has encountered a problem and needs to close." Then I may choose whether to send the error report.
There has been no update. It will not install.
Why does this happen? The only way I can get updates from Firefox is to go to Mozilla.com and download.
I tried the troubleshooting tips in Firefox Help and nothing worked.

I should have explained that this has been going on for a long time. When I first installed Firefox several years ago their updates installed fine.
Then they no longer would install, starting in July 2007 when they downloaded Firefox 2.0.0.4. After they installed that, Firefox would not even open, and I got an error message. I had to uninstall and reinstall.
I figured out over time that I would have to go to their website and download the updates myself, each time they announced that an update needed to be installed. It would then install fine. And Firefox would open as it should. This has been the case for a long time.
So it does work out doing it this way. It is something of a nuisance, and it would be nice if the updates worked smoothly and automatically, as they used to.
I thought this might be some problem others users have had and would know how to fix it.
Thank you.

My webroot tool bar will not install firefox. How to Help needed. I did the reinstall from the start button in windows. Thanks

The toolbar for my webroot account will not install on firefox for some reason. It remembers my accounts and passwords along with the sign in pages of my accounts.

It works again, thanks. It was only a small thing but so annoying. Do you know why this happened so I can maybe avoid it in future?

Firefox will not install addons

After getting a new computer and installing Firefox 12 on it, Firefox will not install addons. The only way that I can get it to install anything is by downloading the .xpi file and manually installing it. Unfortunately, I cannot download the .xpi file to one of the addons that I need to do my work, so this is a problem. Does anyone have any suggestions?

Try to disable hardware acceleration.

Create a new profile as a test to check if your current profile is causing the problems.

If the 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 firefox. it dowloads just fine. It will not install. Says that firefox must be closed in order to continue. it is closed.

I was able to use Firefox until today. it will not open. i tried to update it. It downloads a newer version just fine. WhenI try to install it, it says to close firefox. Firefox isnot open. I also tried to unistall it and it won't let me.

Hi kshikuma. This happens to me sometimes, as well.
To solve this issue, open the Windows Task Manager by hitting Ctrl+Alt+Del.
Go to the "Processes" tab and see if a process named "firefox.exe" or "plugin-container.exe" is opened. Close any and all such processes by right-clicking them and selecting "End Process".
