hi, thank you. unfortunately there was a problem processing past ubuntu crashes properly - can you try to trigger the crash again & submit another batch of crash reports?

unfortunately it's till the same with them... they don't say where and why they crashed in a human-readable way, so unfortunately i won't be able to be of any particular help and it looks like you've already gone through the most basic troubleshooting steps already :-/

There aren't any symbols shown in the crash report.

Are you using a version from the repositories of your Linux distribution or the version from the Mozilla server?

Try the version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.

You can find the full version of the current Firefox release (40.0.3) in all languages and all operating systems here:

• https://www.mozilla.org/en-US/firefox/all/
• http://kb.mozillazine.org/Installing_Firefox#Linux

Ok so what are my options then? I mean, I thought the whole point of a crash report was to provide debug info. Is there anything else I can do to make these crash reports better?

cor-el, i'm using the one from the official repos. Can't see why it wouldn't work. I'm downloading the tar.bz2 file, it says v40.0.3 so we'll see.

The crashed occur in the main libxul.so file (this file is 64 MB), so without any references to what code the crashes occur it is impossible to to check the cause.

Did you make sure that you meet the System Requirements?

• https://www.mozilla.org/en-US/firefox/40.0.3/system-requirements/

cor-el, yes i'm well above the hardware ones. As far as packages goes, i'm also up do date

cor-el, just reproduced using the tar.bz2 archive.

Hello cor-el,

I had a feeling it'd be flash related problem. Thanks for pointing out the two plugins being activated.

For the record, I removed flashplugin-installer 11.2.202.508ubuntu0.15.04.1 and kept pepflashplugin-installer 17.0.0.169~cr42.0.2311.90-1-0skunk0

This seems to work as desired and all seems stable now.

Thanks!
