This makes Firefox unstable and it frequently freezes, especially if an additional window-- for example, if I try to attach a file for a gmail message, the "browse" window to locate the file results in firefox freezing. It also happened when I opened up the download window to open a download. The opening of the download windows caused firefox to freeze (again this only happens when a large number of tabs are open). I used to run multiple tabbed windows in earlier versions of Firefox (since the tabbed was first released), and did not have this problem. There seems to be a bug causing Firefox to freeze because a large number of open tabs. Reproducible: Always Steps to Reproduce: 1. open firefox with 30 tabs (this also happens if you multiple tabs and a new browser windows (i.e., control-N and multiple tabs) 2. go to a web page where you need to perform a "browse file" to open an attachment-- for example, go to gmail, compose an email, and try to attach a file to the email 3. This should cause firefox to become unstable and freeze. Actual Results: firefox froze Expected Results: not become frozen I run vista 64-bit
Can you reproduce this if you run Firefox in teh Firefox safemode ? http://support.mozilla.com/en-US/kb/Safe+Mode
I opened 65 windows and could not reproduce, please reopen if you can in safe mode.
