Created attachment 457044 [details] [diff] [review] patch We have only partial support for this right now, and it's regression prone since we don't use <popup> ourselves anymore.
Comment on attachment 457044 [details] [diff] [review] patch This is ok but you should document this somewhere and inform others about this change. Also, Thunderbird and Seamonkey (for example) do still have <popup> throughout their code.
updated https://developer.mozilla.org/en/Firefox_4_for_developers#Miscellaneous_XUL_changes and https://developer.mozilla.org/en/XUL/popup and filed bug 578440 and bug 578441
This broke pop-ups from right-click context menus for addons that are in the status-bar, i.e. ABP, AniWeather, or any addon that for now works in the status-bar. The context menu shows, but it is 'transparent'. Intentional that they broke, or was this for 'themes' only ?
It affects add-ons that use <popup> instead of <menupopup>, it has nothing to do with the status bar per se.
Two more extension that are affected Live HTTP Header, AdBlock Plus (bug 584566)
