This bug is a copy from https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/323912

Are you sure that it only crashes with adblock because the stack trace looks just like another VLC crash

Comment 3

[hawran]

I understand it seems odd (according to the backtrace). However, I'd done a couple of tests:

1) run FF in -safe-mode => nothing happened
2) run FF and disable Adblock Plus for that domain (http://www.ceskatelevize.cz/) => nothing happened
3) run FF with Adblock Plus enabled => every click on the links I'd mentioned before means crash and a core file.

Attempted to reproduce using Mozilla's build of Firefox 3.0.5 and Ubuntu's packages for VLC and its plugin on Kubuntu 8.04 and got no crash.

_fini usually means module unload or app shutdown....

Comment 6

[hawran]

Hi,
What about trying it with my adblock blocked sites list?
Could it help?

Closing old bugs in the Plugins component. We aren't going to track issues in 3rd-party plugins in the Mozilla bug tracker. In addition, support for NPAPI plugins will be removed at the end of this year; for more details see the post at https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/

If there is a serious bug in Firefox, it needs to be filed in the "Core" product, "Plug-Ins" component.
