firefox crash when rearranging bookmarks

[Francesco Potortì]

after upgrading to Hardy, with Mozilla/5.0 (X11; U; Linux i686; it; rv:1.9b5) Gecko/2008041514 Firefox/3.0b5, Firefox hangs with 100% CPU usage if I try to drag a bookmark entry in the bookmark drop-down bookmarks list.

I click the Bookmarks menu, I click on a bookmark, then I drag it: Firefox freezes, CPU usage goes to 100%, X is unusable. The mouse pointer moves, but clicking or pressing keys does nothing. The system monitor on the Gnome panel keeps working. In two instances I switched to a console and killed Frefox from there, so I could keep working. In a third instance, switching to a console showed a corrupted screeen, and I was unable to kill Firefox even by blindly typing "killall firefox", not could I manage to kill X by hitting Ctrl-Alt-Bksp, so I had to hit the reset button.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" [WWW] http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at [WWW] http://wiki.ubuntu.com/DebuggingProcedures

Please check for crash reports in /var/crash.

Is this the only time CPU hits 100% as there is a known issue of this bug without moving bookmarks. Can you please obtain a backtrace following the instructions at

https://wiki.ubuntu.com/MozillaTeam/Bugs

 I have updated it breifly for firefox-3.0 and please attach all extentions plugns addons that you have for firefox-3.0 for plugins you can go to "about:config" without the " and click file>save as and save it than attach it here. for the next bug report on firefox please use Help> Report a problem from firefox menu as it will attach needed files but not crash/backtrace reports.
You aare most likely not going to find anything in /var/crash as apport is turned off by default in stable releases of Ubuntu

to kill firefox process you need to use the PID by running "ps aux | grep firefox" without the "

Sorry for not following up, but I discovered that my newly upgraded system has a more serious problem, as it resets all by itself, sometimes after few minutes from start. I suspect something broken related to my ATI Radeon video card.

Thank you for the instructions on how to diagnose this problem. However, since it will take time to do so, I will try to follow up on this issue as soon as I can, but not immediately.

By the way, "while you can run "killall firefox" even on a nonfunctional console, you cannot run ps aux | grep firefox" blindly :)

firefox crush when I do this:

Organize bookmarks -->I accidently drag All Bookmarks into a sub directory -->click the sub directory of All Bookmarks -->Library crushed

All Bookmarks should not be able to copied into its sub directory

[Francesco Potortì (pot)]

I upgraded my box, including motherboard, processor and graphics card (in practice, a new box) but retaining the system on disk. I cannot reproduce the bug any more. Either because it was fixed in the meantime, or because of the new graphics card (it used the ati xorg driver, now it uses the proprietary nvidia driver).

As far as I am concerned, this bug should then be closed.

Joey's report is different from the original one that I had reported, so maybe should be moved into a different bug report.

[John Vivirito (gnomefreak)]

Closing due to reports comment above that it is fixed.
Joey please file a separate bug report for your issue as it is not the same.

The exact same problem that Francesco reports above has happened to me a number of times; and often I'll then need to reset. After a bit of googling, I found this page. I'm using Firefox 3.0.1 under Xubuntu 8.04, and have attached my about:config, as John suggest.
A workaround is of course to use the "Organize Bookmarks" instead, which has never caused any problems.

I have the same problem

The bug happen when I drag and drop bookmarks to reorder them
The bug is already there when I start a new session of Firefox after having restarted the laptop
The bug happen with the 2 lasts bookmarks (I didn't try more items)

Unbuntu 9.04 / Firefox 3.0.11 / Samsung NC10 laptop
My bookmark list is 49 items long
The bug also happened the list was 48 items long

I didn't undersand if the topic is closed or not because I'm new : I do not understand "statut : Incomplete → Fix Released"
