Binary package hint: firefox-3.0

Go to a specific URL with a video:

Then try to change a quality ("Nizka kvalita" or "Stredni kvalita" or "TV kvalita"):

With Adblock Enabled, Firefox crashes.

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

[hawran (hawran.diskuse)]

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.

I've forgotten:
Adblock Plus: 1.0.1

I've just copied the bug's description to https://bugzilla.mozilla.org/show_bug.cgi?id=476353

[Davemgarrett (davemgarrett)]

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....

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

[John Vivirito (gnomefreak)]

waiting for upstream comments.
I'm not confident this is a firefox issue as apposed to adblock issue. can you please post the output of apt-cache policy adblock-plus

[hawran (hawran.diskuse)]

Hi John,
Here we are:

...@...:/home/... $ apt-cache policy adblock-plus
adblock-plus:
  Installed: (none)
  Candidate: 0.7.5.4-0ubuntu1
  Version table:
     0.7.5.4-0ubuntu1 0
        500 http://archive.ubuntu.com hardy/universe Packages
...@...:/home/... $

[John Vivirito (gnomefreak)]

Please install our package and see if you can reproduce. As i recall our package didnt crash but upstream did. This was a while ago and i dont see any other bug with this issue when user is using our package.

[hawran (hawran.diskuse)]

Hi,
To be honest, I don't know what do you want me to do. I'm a regular user, not a linux guru, :-(

??? "install our package" ???

What am I supposed to do, please?

[John Vivirito (gnomefreak)]

Closing this task since i cant reproduce this issue in Ubuntu sing Ubuntu's package.

To install a program you would do it was you normally would using Ubuntu's archives in /etc/apt/sources.list. I suggest you open synaptic and serarcvh and use that to install packages. You not being able to install package fro Ubuntu arcive is not a firefox issue. Please reopen once you have removed the version of adblock-plus that you got from Mozilla plugins page and install Ubuntu's version and and tested to make sure it is reproducible
