Happend again. just now. . its so frustrating.

Crashing FF everytime
It appears to happen more frequently qhen I am logged onto a secure site https//
Anyone has any suggestions. I have uninstalled FF in safe mode. Reinstalled, removed previous user profiles etc.
There's very little information I could find about sharedobj.dll, but it appears to be causing a lot of IE8 users problems, too and may be malware. Since sharedobj.dll doesn't come with Firefox I would not expect reinstalling Firefox to help.

If you could attach a copy of the file to this bug report we could investigate it. You could also upload it to and see what they say about it. If not that'll be the first thing I try with it.

the many links off of this set of search results tell of people having problems with shareobj.dll

some have suggestions on procedures that might help to remove.
I no longer have this issue. The problem seemed to go away when certain plugins were removed or an update was reversed. I remember getting an email from Mozilla about a conflict with a Microsoft plugin or similar and it was removed by Mozilla.
for the record,

however, since you're happy, "WORKSFORME"
