Sometimes when I start Mozilla the URL bar is completely empty (except for the icon). It won't accept anything, but one can click on bookmarks to get around (or links on pages), however, the URL bar is still empty and does not show the current URL. There is a very easy workaround. I click on Mail, close the previous navigator window, open a new navigator window from Mail and the URL bar is alive again. This happens randomly at startup, every fourth time or so. I'm using a nightly build from the 1.0 branch (2002052909) but I've noticed this with a few previous versions too. I think it started after RC1 or 2.
related/dupe of 131627?
not a dupe of bug 131627 but I'm sure they're both a supe of something I've seen but cannot find now

I don't think this is a dup of the "sometimes can't enter stuff in textboxes" bug. This bug also caused/causes the location bar to not update when a new page loads.
