Red Hat Bugzilla – Bug 200404
firefox closes without any warning at some websites
Last modified: 2007-11-30 17:11:38 EST
Description of problem: firefox 1.5.0.4 for FC5 closes without any warning when trying to open the site http://www.dluxproductions.com/webcandy/ This is not the case for other fedora releases where firefox 1.5.0.4 is installed. Windows version can open this site without a problem too. Initially thought its a plugin problem but all the necessary plugins are installed and yet it craches at this particular site (may be others too). Please check the fedora list for details https://www.redhat.com/archives/fedora-list/2006-July/msg03579.html Version-Release number of selected component (if applicable): firefox 1.5.0.4 How reproducible: Almost everybody who are using FC5 are getting the same results regardless of their varieties of plugins. Steps to Reproduce: 1. visit this site http://www.dluxproductions.com/webcandy/ 2. 3. Actual results: firefox closes without any warning. If you "ps -A | firefox" to kill the process, firefox starts from nowhere. Expected results: firefox closes without any warning sign before loading the page. If you "ps -A | firefox" expecting to get the process number of firefox, the browser appears from nowhere. Additional info:
What happens if you do this: 1) Close firefox completely. 2) export XLIB_SKIP_ARGB_VISUALS=1 firefox 3) Open that URL Any difference?
What happens if you do this: 1) Close firefox completely. 2) export XLIB_SKIP_ARGB_VISUALS=1 firefox 3) Open that URL ================= did same: export XLIB_SKIP_ARGB_VISUALS=1 firefox and opended that URL but the problem remains same (firefox closes unexpectedly).
I find that accessing the URL via an email link works. However, any other method I've tried (web page link, bookmark, copy and paste) reliably crashes the browser. It's definitely due to the flash plugin, since if I uninstall the flash-plugin RPM, leaving all other plugins installed, I can access the page.
BTW, when you run 'ps -A | firefox', you're restarting the browser. To get the PID you want 'ps -A | grep firefox'.
please check the fedora list link above. If its the flash related problem, why some people with other versions of FC and firefox 1.5.0.4 with flash plugin were able to access the same site without any problem? most of the post reported crashed were FC5 users. I guess it may not be the problem in firefox itself but something to do with FC5.
The first few people who responded said they could view the page. After that, everyone else said it crashed. I think the first people to respond were subscribed to fedora-list and were testing the link by clicking on the email link, which would work. The later people could have been reading the fedora-list archive and been clicking on a web page link, or copying and pasting the link, which would crash. (I'm guessing, but it's a plausible theory.) And I think this problem has existed before FC5. I will ask my father who still uses FC4 to try the link and see if it crashes his browser. Although FC4 is still using an older version of Firefox, 1.0.8 I think. Maybe the bug is limited to the newer Firefox.
I am also suscriber of fedora list and tried the email link to open in new window, result is same.
sorry for the "ps -A | firefox" where it should be "ps -A | grep firefox". My mistake...
By the way I thought its just the firefox problem. I tried with mozilla too and came up with same result. I don't know if firefox and mozilla shares the same engines or they use different ones.
If you are able to reproduce this consistently, then you should be able to get a backtrace. Install the matching firefox-debuginfo and get a complete backtrace using gdb. Attach it to this report. My guess is that this is actually a crash in the Flash plugin, but we need a backtrace to isolate the cause of the actual problem.
I guess you are right. I removed the flash plugin and able to access the site. so actually its not a bug at all. All the post convinced me that it must be a bug. :-) Tried it with mozilla and firefox both without flash and able to access these sites.
