Firefox menu bar under Unity(2D) is too slow for my fingers (on Core2!)

[Alan Jenkins]

Steps to reproduce:

1. Open firefox.
2. Press Alt + V + Y + N, in quick succession.

Expected behavior:
The menu item View -> Page Style -> No Style is activated; CSS stylesheets are disabled, and the menu disappears.

Actual behavior:
My keyboarding gets ahead of the menu. First time, I'm left with the View menu open. Second time, I'm left with the Page Style menu open. On the third time, all the menus are cached & it works fine.

Note that this doesn't happen with gnome-terminal (and Alt + T + C + A).

Note also: Firefox may be treated specially because of the Bookmarks menu. This can contain thousands of items (seriously - if you use tags and ctrl+d, you're going to leave everything in the "bookmarks menu" folder).

I suspect the correct solution is to make sure it's only the Bookmark menu that is populated on-demand; all the other menus should be populated "eagerly", i.e. ahead of time.

Still present in 13.04.

(Note "Open Firefox" means a _new_ firefox. You will need to close your current Firefox, or alternatively switch to a Guest user for testing).

Alan,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Presumably this problem was a one time occurrence and/or is no longer an issue? Can this bug report now be closed?

If we do not hear from you the bug report will close itself in approximately 60 days time.

Thank you for helping make Ubuntu better.

Please do auto-close. I don't have a Unity install to test this on, 2D or otherwise. I don't plan on using community-supported Unity, partly because I think there were other reported bugs that I didn't hear anything about.

Also, it looks as if the root issue is fixed for new Firefox profiles. *If* I create a new profile, then the default folder when creating a bookmark is "Other Bookmarks" (heh). So you don't end up with thousands of items in the Bookmarks menu. Unless you deliberately asked for every one of them.

I wouldn't say the occurrence was a one-off, seems clear from comments that it was consistent. :-P.

Thanks Alan. Marking as "Invalid" as issue never reached "Confirmed" status.
