firefox crash segfault (core dumped) with some websites

[Kurt J. Bosch]

Binary package hint: firefox

On edgy
doing a
/usr/bin/firefox http://techgage.com/article/sabayon_linux_32
leads to
Segmentation fault (core dumped)
here.

Most other Websites seem to work with no problems.

I could reproduce this even with an extra user-account without special firefox-addons installed.

I installed vanilla firefox into /opt like described in
http://wiki.ubuntuusers.de/Firefox/Installation
It worked with no Problem for some time, but crashed again later.

dpkg-query -W -f '${Status} ${Package} ${Version}\n' |grep ' installed '|grep 'mozilla\|firefox'

I am unable to reproduce this on a fresh install of edgy.

[Kurt J. Bosch (kujub-deactivatedaccount)]

OK - I tried it again and now it happens with the non-ubuntu firefox too.
Seems to happen offen but not every time.

moved plugins dir away - problem was gone away

page containes flash stuff

restored plugins dir

dpkg-query ... '*flash*'
flashplugin-nonfree 7.0.68~ubuntu3
install ok installed libflash-mozplugin 0.4.13-8ubuntu1
install ok installed libflash0c2 0.4.13-8ubuntu1

sudo apt-get remove flashplugin-nonfree

happens again

sudo apt-get remove libflash-mozplugin

fixed (but no flash any more)

sudo apt-get install flashplugin-nonfree
automatic installation failed due to network problems or upstream changes

installed flash-plugin using firefox

now it works (again)

hope this solved it now :)

Please install flash 9 from your backports repo and if you are able to reproduce this please reopen the bug with the full crash report or backtrace.
See for help getting a backtrace https://wiki.ubuntu.com/MozillaTeam/Bugs

[Kurt J. Bosch (kujub-deactivatedaccount)]

The problem seems to be related to libflash-mozplugin
*not* flashplugin-nonfree.

What I did to reproduce:

sudo apt-get install flashplugin-nonfree/edgy-backports
Result: firefox worked without problem three times

sudo apt-get install libflash-mozplugin
Result: firefox worked without problem three times

sudo apt-get remove flashplugin-nonfree
Result: firefox is crashing each time

sudo apt-get remove libflash-mozplugin

Result: firefox worked without problem three times
 (but without flash)

Some Notes:
I started firefox using path /usr/lib/firefox/firefox
this time, because my symlink /usr/bin/firefox is diverted.
I restored /etc/firefox/firefoxrc to normal.
I used an extra user account (unchanged) with gnome for testing.

Problem appears with webpage
  http://techgage.com/article/sabayon_linux_32

[John Vivirito (gnomefreak)]

Changed to libflash.

[Alexander Sack (asac)]

can you please test with flash player 9 installed?

[Kurt J. Bosch (kujub-deactivatedaccount)]

With flashplugin-nonfree 9 (edgy-backports) there is no problem.

Occures every time when only libflash-mozplugin is installed.

If both are installed there seems to be no problem too.

It used to happen when libflash-mozplugin and flashplugin-nonfree 7 (multiverse) where installed, but installation of flashplugin-nonfree 7 seems no longer possible.
'automatic installation failed due to network problems or upstream changes'

I attach about_plugins (flashplugin-nonfree 9 only). Don't know if any of the other plugins are relevant here.

I have this crash on a fresh install:

Xubuntu 7.04 Feisty, i just installed it;
Firefox 2.0.0.3 - installed from the repository;
libflash-mozplugin 0.4.13-9ubuntu1 package installed;
libflash0c2 0.4.13-9ubuntu1 package installed;

This happens when i try to load a page on youtube.com.

Hi had these problems too, I think because I had flash installed directly from adobe and java installed directly from sun (then adpet didn't know about them). The dist-upgrade didn't recognize that these were there and needed to be re-installed with the new firefox. To fix Uninstall firefox and all firefox plugins that you canfrom within adept then rm -rf all firefox and mozilla directories in home folder and lib. see sudo find / -n '*firefox*' and sudo find / -n '*moz*' Then reinstall firefox and plugins from adept and reinstall flash from adobe.

Does anyone still have this issue based on packages from official Ubuntu archives? If not, I will close it within the month if we can no produce a reproduceable case. Also, lowering the importance based on comments.

I didn't experience this any more, for a long time.
