Opening the Bookmarks menu (not the toolbar widget!) causes the menu to "jitter" - it flickers and jumps up and down. This appears only to happen if the list is longer than the distance from the menu bar to the bottom of the screen (i.e., it has to render part of the menu above the menu bar.)

If this was with an M13 or older build, it has been fixed. what build were you using? please read http://www.mozilla.org/quality/bug-writing-guidelines.html or use http://www.mozilla.org/help/bug-form.html

Sorry - I first tried using the long bug form, but it failed to copy the info into the "standard" bugzilla form. So I re-wrote it (and in the process missed the build...) Yes, this was with M13. Since builds seem to be coming slower since alpha, perhaps I'll get the source and just start doing periodic CVS builds...

mozilla still puts out nightly binaries.... resolving this bug as invalid since it applies to an already fixed bug in an old build.

VERIFIED.
