Firefox downgrades to earlier version
I am running WIndows 7. I have admin rights (this is a work computer). I have upgraded Firefox to version 40.x (several times). I have deleted the previous version (29.0) using both Control Panel Uninstall and manually removing the Mozilla folders.
The upgrade works fine until I logout/restart. Then version 29.0 is what is running (and now present in the Uninstall control panel). Of course, Firefox wants to upgrade this version but at this point I may have to use Chrome (please no!) rather than upgrading every session.
I've called the big guys to help you. Good luck.
Separate Issue; Your System Details shows;
Adobe Shockwave for Director Netscape plug-in, version 22.214.171.124
Adobe Shockwave for Director Netscape plug-in, version 126.96.36.199
Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.
In your Windows settings is there anything that says to restore to a previous version on restarting your computer?
