However, if an extension is installed that adds a context menu entry that contains a submenu, and the cursor is placed over that entry to expand the submenu, then both the Back and Forward context menu entries are enabled, regardless of whether or not the page has a back/forward history. Reproducible: Always Steps to Reproduce: 1. Install an extension that will add a right-click context menu entry that contains a submenu for more functions (such as Tab Mix Plus, Linky, View Formatted Source, etc.). 2. Right-click on a page that either has no history, or either back or forward history (but not both). 3. Move your cursor over one of the extension-added context menu entries that has a submenu. Actual Results: The Back and Forward entries are both enabled, regardless of whether or not the page has a back/forward history. Expected Results: The Back and Forward entries should only be enabled if the page has a back/forward history - otherwise, they should remain disabled.
Reporter, can you confirm that this is still happening to you? Does it only occur when you have more than one tab open? Can it only occur when there's a single tab open? Can you try installing the latest 1.0.6 build, available at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-aviary1.0.1/ WFM, I don't see the problem on WinXP SP2, Deer Park Alpha 2, View Formatted Source extension installed.

I tried this out again, and it happens regardless of whether I have more than one tab open, or just one tab open. I also went ahead and used a cleaned-out "testing" profile (only installing one or two extensions with context menu submenus so I can test this) to make sure it wasn't a profile issue - it occurs there, too. After this, I did as you said and installed the most recent 1.0.6 nightly (20050810, same profile as before) - it still happens. I then noticed that you also said you were using Deer Park Alpha 2, so I went ahead and installed the most recent version of it (again, using the same profile as I did before)...This time, though, it didn't happen. Since it works with Deer Park Alpha 2, maybe only the 1.0.x versions (and possibly earlier versions of Deer Park) are affected by this?
This is strange...After uninstalling both Deer Park Alpha 2 and the Firefox 1.0.6 nightly that I installed earlier, and reinstalling the official Firefox 1.0.6, this problem doesn't occur anymore, in any of my profiles. Could it be possible that something was left over from a previous installation of Firefox that was causing this, which was then fixed by uninstalling and reinstalling it (as opposed to just upgrading an older version without uninstalling the previous one)? I'm not sure why uninstalling it before now didn't fix this, but for some reason, this time it fixed the problem.
