User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20120826 Firefox/15.0 SeaMonkey/2.12 Build ID: 20120826214753 Steps to reproduce: Browser crashing while using phpmyadmin (latest 3.5.x), specifically the edit query popup window. This happens on both Seamonkey 2.12 and Firefox 15. This is happening every time within about 45-60 minutes of constant use of phpmyadmin and the edit query popup window. Eventually with the edit query window popup open, the browser will start choking on drawing elements of the popup window, then eventually crash. The crash will sometimes generate a report, all so far without an identified thread or proper core dump, other times it will simply just crash without detecting it crashed (just silently closes down). Suspect a memory leak, possibly related to jquery and/or jquery-ui as I think phpmyadmin relies on this heavily. Note that prior to SM 2.12 and FF15 the browser was stable with PMA and did not exhibit this issue. Actual results: Seamonkey crash reports: bp-6a12620b-1d82-4db7-b091-34d2f2120903 bp-dd365471-d044-4169-ab36-cd19b2120902 bp-96886944-0ab7-43e8-924e-fc5992120902 bp-c25c8dab-1321-47b2-83ce-ba9a92120902 bp-fd46f920-a74e-41be-9d96-f41112120902 bp-fb195588-1a0a-4d05-945e-15b042120902 Firefox crash report: bp-0b770cf6-a72a-4beb-ae3a-ff5cf2120903

Those crash reports can't be exploited. Does it happen in Safe Mode (see https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode)? Can you provide a stack trace (see https://developer.mozilla.org/docs/How_to_get_a_stacktrace_with_WinDbg)?

Hi, I setup WinDbg and the browser crashed at startup this time. Crash report: bp-46507957-c5c6-4bdf-8d1c-dd6942120906 Also attaching a stack trace of the session.

(In reply to Jeremy from comment #2) > Crash report: bp-46507957-c5c6-4bdf-8d1c-dd6942120906 It's caused by your graphics driver. This AMD display driver version seems crashy because it causes also crashes on Windows 8. Disable HW acceleration as a workaround: https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration#w_turning-off-hardware-acceleration

Thanks, this makes sense as phpmyadmin uses jquery-ui heavily. Have disabled HW acceleration as workaround and is working much better. Thank you.

Let's dupe to a bug with a better stack trace (same signature).
