Firefox 3 Repeated Random Crashings

[Dat]

Firefox 3 keeps randomly crashing. I noticed it started happening after I installed Cairo-Dock so I'm pretty sure its related. I'd like to keep Cairo-dock if possible but how do I figure out what's causing the crashes and how would I go about fixing it?

I installed Firefox via Adept when I first performed a clean install of Kubuntu 8.10. It's been running fine up until recently, when I installed Cairo-Dock via Synaptic.

Firefox just crashes when I'm browsing sites, such as these forums or even checking gmail or something of the sort.

Re: Firefox 3 Repeated Random Crashings

I'm not entirely convinced that Cairodock is causing the crashes...seems unlikely to me.

If you are sure its CairoDock, then I'd suggest you contact the CairoD devs...cause the problem is probably on their side. FF source gets a *lot* of eyeballs...CairoD not so much.

However, 99% of FF crashes are due to plug-ins and/or flash/Java. Try disabling all add-ons and disabling Java+Javascript and see if that helps. I trust Java and FF are up-to-date?

I'd also suggest a few hours of memtest. Not because it is likely to be the problem, but rather because it helps strength your case if you can tell the devs that the rig is stable.

Clearing the FF cache also fixes some quirks...but I don't think it will help here.

Run firefox from a terminal, keep the terminal open, when it crashes you may get some helpful info in the teminal as to what caused the crash.

Re: Firefox 3 Repeated Random Crashings

I set Firefox to automatically clear the cache on closing. It should be up-to-date since I don't see any update requests.

I ran firefox from terminal and got the following when it crashed:

dat@Dat-HP:~$ firefox
QPixmap: Invalid pixmap parameters
The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
 (Details: serial 38203 error_code 11 request_code 53 minor_code 0)
 (Note to programmers: normally, X errors are reported asynchronously;
  that is, you will receive the error a while after causing it.
  To debug your program, run it with the --sync command line
  option to change this behavior. You can then get a meaningful
  backtrace from your debugger if you break on the gdk_x_error() function.)

Re: Firefox 3 Repeated Random Crashings

Looks like you ran out of memory. What are you system specifications? How much installed RAM do you have? How much swap space do you have allocated?

Re: Firefox 3 Repeated Random Crashings

I have 2 gigs of RAM. How do I check how much swap I have? Firefox never crashed before. It crashed just now when I was trying to post a response to this thread.

Re: Firefox 3 Repeated Random Crashings

In a terminal run:

sudo fdisk -l /dev/sda

That's an small L not big I

Assuming you have Kubuntu installed on your first hard drive.

Copy and post the results here.
