[Sage] Nightly Sage makes FF almost unfunctional

[Dmitry Semyonov]

Hi.

This was happening to me sometimes, but recently I figured out how to 
reproduce the issue. I've seen the bug on dial-up ~49Kbit connection 
under Win2k with all except Sage (nightly) extensions disabled. Have 
not tried in different environment yet.

 * Add the following feed to sage bookmarks list: 
http://www.dp.ru/exportnews.xml
 * (Restart FF (?))
 * Open Sage side-bar, and click on added bookmark
 * Wait till the feed contents is rendered
 * Enter the following link to the FF address bar, and press enter:

 * After a few seconds FF almost hangs instead of opening 'Save File' 
dialog. Only Ctrl-TAB as well as mouse clicks to some browser elements 
work. No new windows, no new tabs with content could be opened. Even 
closing FF needs to be performed by killing the process from Windows 
task manager.
