[SOLVED] Firefox crash in 13.1 (32 bit)

fgcl2k · 03-08-2011, 08:11 AM

Firefox crashes when opening http://code.google.com/webfonts.
After recompiling freetype, fontconfig, libXft, cairo and mozilla-firefox (3.6.14), as suggested in http://www.vcn.bc.ca/~dugan/slackware-fonts/ I noticed the crash.
I have reinstalled the original 13.1 packages (and rebooted):

freetype-2.3.12-i486-1
fontconfig-2.8.0-i486-1
libXft-2.1.14-i486-1
cairo-1.8.8-i486-3
mozilla-firefox-3.6.3-i686-1

but the crash still occurs every time on the same page.

I have tried Xfce (with and without antialising) and fluxbox without success.

Do you have any suggestions? Do you experience the same crash?

Thanks,

fgcl2k

Working fine here with Firefox 3.6.15 from Mozilla, not from Slackware package

FYI, i'm running -Current

I have had a similar problem with firefox recently. It would crash (stop completely with an error message) on some web sites. I have upgraded to the most recent firefox as well as the java plug-in. It did not always happen at the same site, and I could go for a day or so between crashes. As my computer was somewhat new, I thought I might have a hardware problem, but no other program crashed. When I went back to another computer to test, I noticed that I had changed the fonts under preferences on the one that was crashing. I had set arial for most fonts, but I reset the fonts back (to the original?) to serif for proportional, sans serif for sans serif, monospace for monospace, and bitstream charter for serif. It has been several days and I have not had a crash. Just something to check.

Wow, I get a crash on that page too. Haven't had Firefox crash on any web page that I can remember but that one does a good job of it. I haven't messed with any fonts that I know of (other than running Microsoft's webcore fonts), though my Firefox is not plugin-/add-on-free so I don't know if it's related to those or not.

Seamonkey also crashes on that page on my computer.

It's fine on x86_64 with Stock Firefox .14 here.

T3slider · 03-08-2011, 04:56 PM

It crashes on Slackware64 13.1 in stock Seamonkey as well (seamonkey-2.0.11-x86_64-1_slack13.1) for me (and mozilla-firefox-3.6.14-x86_64-1_slack13.1, though with addons). GazL, are you using -current or 13.1?

GazL · 03-08-2011, 06:47 PM

Ahh, good point. It's current I have. It's that stable I tend to forget.

I'm running a fully updated 13.0 with a custom kernel, but I have no issues at all on that page with FF 3.6.14. I am running NoScript and Adblock+, though. They may be blocking what is causing your issues.

I have further investigated the problem, running firefox under the debugger:

Code:

$ /usr/lib/firefox-3.6.3/run-mozilla.sh -g /usr/lib/firefox-3.6.3/firefox-bin -d gdb

When I open http://code.google.com/webfonts:

Code:

libpangoft2 belongs to the pango-1.26.2-i486-1 package.

Firefox can open that page without crashing only if disable "Allow pages to choose their own fonts, instead of my selections above" in the "Preferences|Fonts" dialog box.

You can kill Pango permanently by adding this to your /home/<user>/.bashrc:

Code:

export MOZ_DISABLE_PANGO=1

I always run with Pango disabled. It gives FF a wonderful speed increase, too.

Luck!

It doesn't seem to make any difference; it looks like the setting is ignored. Firefox crashes and I get the same error. I did a quick search and tried without result the following settings MOZ_DISABLE_PANGO=1, MOZ_DISABLE_PANGO=0, MOZ_ENABLE_PANGO=0, MOZ_ENABLE_PANGO=1.

I am now trying to recompile firefox with --disable-pango.

Thanks for your help,

It works. I have compiled mozilla-firefox 3.6.15 with --disable-pango and it no longer crashes on http://www.google.com/webfonts.
