I am the Windows admin for a university department and install PCs with Firefox all the time. This problem does not happen with every PC I maintain, only a select few (different model laptops with Windows 8.1 and update 1.) Until today, it only happened with new user accounts (with admin rights) that I setup on the laptops for our staff. Today this happened with The Administrator account while setting up a new laptop. In all cases so far, I install Windows from a saved image that was created using sysprep.
I have tried the many suggestions of resetting Firefox, deleting the users Firefox profile, deleting the users Windows profile, uninstalling/reinstalling Firefox, uninstalling/reinstalling Firefox and the latest Java, but nothing helps. After uninstalling, I run an app to delete temp files and caches and will even manually remove registry keys HKLM\SOFTWARE\Mozilla and HKCU\SOFTWARE\Mozilla. Plus I reboot and make sure the install folder is deleted after uninstall.
Results are the same: after installing Firefox 31, the initial setup window for migrating IE and/or Chrome pops up and after clicking the Finish button, Firefox starts, but does not show the initial new user page, only a blank page. Clicking on the Options button (3 bars) does nothing. Right-clicking in the proper area, the popup menu appears so I can choose to Customize, but that only opens another tab with about:customize in the URL and the page is blank. From the right-click popup menu, I can enable the Menu Bar and get to Options from that.
My latest attempt has helped a little. I uninstalled Firefox 31, cleaned up, deleted user Firefox profile, rebooted and then installed Firefox 30. Inital startup runs, and tells me I'm not up to date, and the Options button works. But I still cannot customize.
I then upgraded to Firefox 31, but then it's back to no startup page, no options button and no customize. I can downgrade to 30 and get all but customize working again.
Only Addon is one for McAfee Scriptscan for Firefox 15.1.0, which just after installing is disabled.
Any help would be appreciated. Thank you.
