User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.8) Gecko/2009032609 MRA 5.4 (build 02647) Firefox/3.0.8

Sometimes upload file picker that is activated automatically when you click on any "file" form element or its browse buttons slows down entire browser greatly. It seems to happen after long period of work or with many open windows. When file picker is opened, it either responds to mouse and keyboard actions very slowly or doesn't respond at all. Since dialog is modal, entire session with all open tabs is affected as well, often leaving you to either blindly pasting file name from clipboard and hitting "enter" and then waiting for a minute for those actions to be recognized or forcing you to terminate Firefox completely.

Restart often solves the problem for some time, but it seems I've recently managed to capture a session state with "Session Manager" add-on that make this incorrect behavior to happen every time.

Other file pickers, such as one called with "Save as..." command seems to be unaffected.

Same problem is also described by another user on support forum: http://support.mozilla.com/tiki-view_forum_thread.php?forumId=1&comments_parentId=290809

Reproducible: Sometimes

Steps to Reproduce:
1. Work for extended period of time and/or open many tabs or windows.
2. Activate "file" type element in form.
Actual Results:  
Firefox becomes unresponsive.

Expected Results:  
Firefox should perform without slowdown/hangs.

After hitting this several more times, I have to add that other file pickers ("save as" for example) actually ARE affected too.
