Firefox after upgrade/restart behaves like crazy...

Hi!

When restarting Firefox, tabs are always blank, no tab history, but "normal" browsing history OK.

When bookmarking all tabs, this kind of warning appears :

Assertion Failed ASSERT: undefined Stack Trace:

for every tab that was open. After them a "New Bookmark" empty window appears (only window title line with "X" close button and title text visible, i.e. small window). Happens to normal and pinned tabs. Folder with the creation time is created in Bookmarks menu, but they are all empty.

Changing settings from Options->History->Firefox will: from "Remember history" to "Use custom settings for history" reverts back to "Remember history" after restart.

After last update to 15b3, I can't even open new tabs!! And from Options, I can't see the first three pages, General, Tabs and Content.

The first issue (blank tabs after restart) has happened before, but the tabs came back after another restart. Only after updrading to 15.0 beta 1 has this been constant, and I tried to downgrade to previous stable/beta (no clean install), but the problem persists regardless of version/branch.

Since these problems seem to come one after the other, and now that the browser seems somehow 'locked', I was thinking maybe some critical file somewhere is stuck/locked/overflowing or something.. And I don't have time to try and solve this myself, as it would obviously require some deeper knowledge than I possess.

System: Windows 7 Ultimate x64 Firefox 15b3 32-bit 4GB memory

One more problem: trying to get the info from Help -> Troubleshooting Information does nothing, no window opens, no dialogs, nothing :/

What's the problem, how to fix it? Any suggestions? What more info might You need? Anybody else having the same issues? Thanks!

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

See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still 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.

Thank you cor-el, the newly created profile works smoothly, no problems as of yet.

I thought the creation of a new profile would correct the problems, but I'm usually a bit reluctant to start all from the beginning to get rid of bugs; I'd much rather apply a "surgical" solution, e.g. I have never reinstalled Windows because of slowness or of any other of the huge amount of problems usually faced with when running the same instance of Windows years in a row, but tried always to clean registry, uninstall programs etc.

Now I have too many other things to do, so I think I'll just swallow my pride and start to move settings and files etc. to get a familiar browsing experience :)

You're welcome

If there are multiple issues in a profile then it is best to start from scratch with a new profile.
Single issues with a clear cause are usually easy to fix, but multiple issues can take considerable time assuming that you find and correct them all.

The new reset function in Firefox can also port issues to the new profile if it involves importing corrupted data.
