The context menu is opaque for me. Mozilla/5.0 (Windows; Windows NT 5.1; rv:2.0b3pre) Gecko/20100722 Minefield/4.0b3pre ID:20100722041142

Hm, does it reproduce on 20100721 for you? I'm guessing it was fixed in 20100722, but I can't find it in the changelog.

Fixed by bug 571567.

(In reply to comment #3) > Fixed by bug 571567. Oh well. It has been fixed for quite a while and no other edit happened for: http://mxr.mozilla.org/mozilla-central/source/toolkit/components/viewconfig/content/config.xul So I wonder why you have seen that. I haven't noticed that all the last days on all platforms. Can you please go back to 100721 and re-test with a clean profile? Just to make sure I was correct. Thanks.

Hm, I'm still seeing this on 20100723, but not in Safe Mode, so I guess it's just me. Must be one of my extensions. I should've tested first before filing a bug. :/
