I haven't been able to recognize a pattern as to when it will freeze and when it won't yet. Reproducible: Sometimes Steps to Reproduce: 1. Just grab a side and try to resize the window. 2. 3. Actual Results: Sometimes it freezes, sometimes it doesn't. Expected Results: You can't predict when it will or will not freeze. It shouldn't freeze. :)
Does it freeze/hang or crash ? (Summary: crash, comment: freeze) Did you already tried the firefox safemode ?
I'm experiencing the same. It seems to be touched off when wordwrap changes the display of text on the page, though I'm not 100% sure about this; gmail was setting it off for me pretty consistently -- and so did this webpage when I tried to resize the page a little while ago. Now resize works. No such issue in the previous update. I'm running Windows 7 RC 1, by the way.
Did you try the steps listed above? Safe mode, new profile, stacktrace? https://developer.mozilla.org/En/How_to_get_a_stacktrace_for_a_bug_report. Also, is this a freeze or a crash? Very important to know the difference.
I honestly don't know how you're defining the words freeze and crash. I don't see the "Crash Reporter". It locks up Vista to the point that I have to do <Ctrl><Alt><Del>, run Task Manager, and then end the process. I tried Safe Mode and it doesn't make a difference. I been noticing the problem occurred with a particular website a lot. So I went to the website and played with different pages until I could find one that would crash it constantly. Unfortunately, the URL won't do you any good, because it requires a subscription to access the site. I found a page on the site that causes a crash everytime that I try to resize the browser window by dragging the left side. I examined the page's source and it uses frames. To test out my theory that it has something to do with frames, I created the following simple HTML file in Dreamweaver. The contents of the frames, test1.html and test2.html are just a really long text file that I loaded into Dreamweaver and then saved as two HTML files. It crashes Firefox everytime I try to resize the window. Hope this helps you track down the problem. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1 -frameset.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <frameset rows="*" cols="323,*" framespacing="0" frameborder="no" border="0"> <frame src="test1.html" name="leftFrame" scrolling="No" noresize="noresize" id="leftFrame" title="leftFrame" /> <frame src="test2.html" name="mainFrame" id="mainFrame" title="mainFrame" /> </frameset> <noframes><body> </body></noframes> </html>
before you load your testcase, 1. attach windbg (according to the instructions in this url): https://developer.mozilla.org/en/How_to_get_a_stacktrace_with_WinDbg 2. open task manager, right click on firefox, select "go to process" 3. right click on firefox.exe, set priority "low" 4. load the testcase 5. do whatever it takes to make firefox stop responding (we call this a "hang") 6. switch to windbg 7. debug>break 8. !analyze -v -hang 9. click "add an attachment" in this bug report and attach the log generated by windbg (see the instructions from step 1)
based on description, hang, not crash.
This sounds like it is probably a dupe of bug 491700. See comment 14: https://bugzilla.mozilla.org/show_bug.cgi?id=491700#c14
Does this still happen? If true it could be bug 499447.
Reporter, are you still seeing this issue with Firefox 3.6.13 or later in safe mode or a fresh profile? If not, please close. These links can help you in your testing. http://support.mozilla.com/kb/Safe+Mode http://support.mozilla.com/kb/Managing+profiles You may also wish to try with the latest Firefox 4 beta, http://www.mozilla.com/en-US/firefox/all-beta.html.
No reply, INCOMPLETE. Please retest with Firefox 3.6.13 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). If you continue to see this issue with the newest firefox and a new profile, then please comment on this bug.
