Any chance of someone looking at this and responding?

OK, I'll do your homework for you. All crashes occur here: caps/src/nsScriptSecurityManager.cpp:2271

Just above that line, a pointer is created and initialized with another one (in the for loop). The new pointer is then dereferenced. But the new pointer is never tested to see if it is NULL. If it is NULL, then the program will crash. So clearly, sometimes it is NULL. This is an elementary programming faux pas; you always check to ensure that pointers are non-NULL before using them.

Now, perhaps you can stop pointing fingers at add-ons and finally fix FF.

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"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Please see the post directly above yours, particularly the bit about checking that pointers are not NULL. If anything is corrupt, FF should handle it gracefully and not crash.

Anyway, I'll try to do that later. But that code needs to be corrected.

OK, I did as suggested. New profile, copied over only bookmarks, cookies and so on. Reinstalled all add-ons and themes. And FF just crashed again:

bp-1e37fc91-22b7-47e8-97fc-49d972100815 08/15/2010 11:27 PM

Same line of code as before.

I know I'm being a pest, but having a solid programming background, I also know that my spending hours checking for corrupt data may solve my problem temporarily, but the underlying bug remains. FF should NOT crash, but handle the situation. And that pointer not being tested is most certainly sloppy programming. Sorry.

Now I'll go do this the hard way, as you outlined, more hours wasted.

Gah, this is nuts. Based on where the error occurs, can you give me some indication of which category of file might have corrupted data please?

When I made the new profile, I copied over files I need with much info: bookmarks, passwords, cookies, etc, per the link you gave. I did NOT copy over Chrome or Extensions. I reinstalled all add-ons and themes.

Surely the location of the crash would allow you to identify what is causing it, no?

Few more for you....

Your crash report link to this bug report, so you can keep an eye on the developments.

Bug 556861 – crash [@ nsScriptSecurityManager::GetPrincipalAndFrame(JSContext*, JSStackFrame**, unsigned int*)]

Thanks for the heads up on that. It appears that this bug has been around for quite some time now, which is surprising, considering how trivial it would be to prevent the crash.

And more.....
