I update to newest version and then it reverts back to old version. Why?

I have been trying for two weeks to get the new version of Firefox on my computer. Every time I download it it seems to work just fine but when I fire up my computer the next day it has reverted to an older version of the browser.

I tried this yesterday and when I got on my computer today it had reverted back once again to an older version. Anything else I can try?

I know because the little smiley face symbol in the top right of the screen goes away and when I check the what version of firefox I have it is one of the old 31.xxx versions rather than the 37 I had installed.

What smiley face? The one in the chat cloud which is the symbol of the new in-broswer chat interface mozilla has added to Firefox. I have tried what you laid out above and it has not worked. Every time I restart or turn on my computer Firefox has reverted back to an older version. Nothing has worked so far to fix this issue.

Either you have both Firefox 31.0 and 37.0 installed and whatever method you are using start Firefox (say a desktop shortcut) after a reboot is pointing to the 31.0 version and not 37.0

Or something is reverting things to a earlier setup which includes Firefox 31.0 version.

Do you have security software that might be protecting files and folders?

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.

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\"

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.
