Hide tabs in html5 fullscreen

[Marty]

When fullscreen is triggered by html5, the sidebar should disappear.
Now it just stays there which is annoying if you're watching videos.

How to reproduce:
What a video on youtube using the html5 player (the flash version works just fine).

Yes this is very annoying.. in the meanwhile as for a working alternative to verticaltabs for this problem, I found "All Tabs Helper" Firefox extension [https://addons.mozilla.org/it/firefox/addon/all-tabs-helper/?src=api] which is basically an enhancer for the "all tabs" button (the little down pointing arrow which lets you see all current opened tabs) and which also lets you show a list of all opened tabs as a sidebar.
