I'm having a lot of problems with browsers crashing on many sites.
It is happening with Firefox, Galeon and Epiphany and I get this message in the terminal -
The program 'Gecko' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
(Details: serial 99 error_code 8 request_code 146 minor_code 3)
(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.)
Here are two url's which crash all three above browsers every time without fail -
There are many others causing the crashes but the above two are the only ones I can recall at the moment.
I don't have these problems if I visit the sites in Konqueror.
I'm afraid I can't pinpoint exactly when this started happening but I'm assuming it is after some upgrade or other.
