This does not happen if the Bookmarks menu is opened directly the first time and it does not happen on subsequent openings. Reproducible: Always Steps to Reproduce: 1. Start Firefox. 2. Select the Tools menu. 3. Move the pointer over to the Bookmarks menu. Actual Results: Browser hung for a little over a minute. Expected Results: Shown the Bookmarks menu almost immediately.
Actually this bug is not restricted to the situation I first described. I have now seen it (1) when starting Firefox and immediately attempting to open the Bookmarks menu, and also (2) on a subsequent attempt to open of the Bookmarks menu. In case (2) I had been running another app that used a lot of memory, so that opening the Bookmarks menu might have required paging in some data. Unfortunately the disk LED on my PC is not easily visible so I don't know whether this is what happened. In both this case and that of the first use of the Bookmarks menu, it should take a second or two to load data before displaying the menu, whereas normally it would take very little time at all. So I suspect the bug may be timing-related. Note that in case (2) the disk was idle by the time I thought to check it; the browser remained unresponsive for about a minute after that, so the hang wasn't directly due to paging.
Summary: Hang if the Bookmarks menu is first opened while another menu is open → Hang if the Bookmarks menu is slow to open
I believe I'm seeing this in 1.0 PR on Windows XP. It's fairly consistent. I'd add that if I let it whirl sometimes it recovers, and sometimes it crashes hard (with the quality agent most (all?) of the time. I also have a couple of RSS feeds bookmarked via the new RSS button. This is a big pain because I essentially crash the browser everytime I accidentally expand the bookmarks menu. (Note: I'm adding this comment to a few existing bugs that seem to match my symptoms.)

Still present in 1.0 release.

I've narrowed this down to a particular bookmark. The bookmark had a URL of the form <file://///server/share/...>, and the named server no longer exists. I think Firefox asks Windows for an icon for the target of the bookmark and the underlying Windows function attempts to contact the server and consequently hangs. In recent versions of Firefox the first click on the Bookmarks menu would always cause a temporary hang; I don't know what might have caused the change from the originally reported behaviour but it's not really important. I suggest that Firefox should not do anything that requires resolving a UNC path in a bookmark until the bookmark is opened.
Created attachment 196868 [details] My bookmarks file I two am having this problem - First click on the Bookmarks menu and it takes 20 seconds to show the menu. This attachment is my bookmark file. Replace your bookmark file with this one, close all browsers, open Firefox, click on Bookmarks, WAIT, bookmarks show up. I'm using Windows XP, and I think my system is disk-bound, meaning that the hard drive causes more slowness than memory or processor speed on my machine.
I believe that 265475 is a duplicate of this bug.
Glen, I think #265475 is quite different, as it's about startup time and depends on the number of bookmarks and not their targets. I'm changing the title of this to indicate the precise problem I identified.
Summary: Hang if the Bookmarks menu is slow to open → Showing menu item for bookmark of missing share causes hang
