there is. it is know as "Error Console" and is a history of errors
encountered and be rather long.

you access it from menu bar by selecting;

  Tools > Web Developer > Error Console

or press keys;

  <alt+t>, <w>, <c>

"catch 22", you have to have firefox running to access. ;-)


step 1: check your firefox profile.

you did not mention what desktop you are using. i am using kde4, you can
make adjustments for your dte.

to see where it is failing, 1st you need to know if it is you user profile.
open a file browser to your home directory, /home/username, locate hidden
profile directory ".mozilla", rename it to ".mozilla.org". start mozilla
from icon or how ever you start firefox.

if it starts, great. you have a bad profile, which may be an add-on or an
add-on conflict, or something else in your profile.

if not, it is a firefox installation problem and you need to reinstall.

after new install, if needed, leave your ".mozilla.org" file as is, remove
new ".mozilla" directory. start firefox. if it starts, great. if not, you
may be loading a bad rpm package or there are other problems. memory or
hdd? can not say for sure, but both need testing.

step 2: check to see if failure is an add-on. _copy_ ".mozilla.org" to
".mozilla".

from a command, enter;

   firefox safe-mode

if firefox starts, you have a faulty add-on or conflicting add-ons.

while firefox is open, maximize window, press <alt+t>, <a> to open add-on
manager. scroll list to guess2mate number, enable half. close manager,
restart firefox. if opens, open add-on manager, enable half of remaining
remembering where you are in list. repeat until firefox fails. when it
does, start in safe-mode again.

open add-on manager, enable what ever half worked, enable rest one by one,
restart until fail. you now know which is problem. problem may be with the
add-on or it and another add-on are conflicting.

to see if it is conflict, disable all add-ons, enable problem add-on only,
restart firefox. if starts, you have a conflict. if not, you have a bad
add-on if. to test for bad, remove it, reinstall from mozilla.

to find conflict, with problem add-on enabled, enable other add-on by half
until firefox fails. repeat as above.

much luck.

hth.
