Expected behaviour: When I start typing into the URL bar (awesomebar) Firefox suggests possibilities including already open tabs, giving me the "switch to tab" option. I can even restrict the suggestions to tabs only by starting the typing with "% ". Observed behaviour: As above except Firefox suggests tabs only if they are in the same container as the current tab. (The default container does not seem to be special in this respect.) I would like a way to find a tab by typing in part of its URL or title, without having to know which container it is in. Is there any way to achieve this at present? If not, please treat it as a feature-request (or even a bug-report... is the existing suggestions/search feature intended to work across containers or not?)
