confirmed on windows7 and ubuntu14.04
UPDATE: On Windows steps 3-4 ARE necessary (to do the same trick with menu as in Linux video) I'm very sorry, I tested that on Windows 6 month ago, and apparently that part was fixed.
Created attachment 8638965 [details] 3 more STRs - Australis menu popups don't collapse.webm 3 more STRs (tested on Win7). Needinfo me if you need them in text form. If you think that interaction with content (STRs 2 and 3 from this video) is separate bug, feel free to file it.
STR_5: 1. Move "Share this page" toolbarbutton to toolbar. 2. Open http://example.org/ , right-click on the page, click "Share this page" 3. Right-click inside the panel opened in Step 2 4. Click on pocket toolbarbutton placed on toolbar (bonus) 5. Repeat Step 3 6. Click on downloads toolbarbutton placed on toolbar AR: 3 panels opened ER: only one panel should be opened at the time @ Neil Deakin: Please triage this bug (ignored for 17+ months) correctly, if you have time for that. If you're going to call this "edge case", please confirm that you (team) want to keep this bug as long as possible based on that, in favor of "improvements" of searchbar, locationbar, new bookmark panel etc. that only break UX.
