Is this irritation a know bug, do others experience the same thing ?

- When playing a html5 Youtube video, switching to a different tab for some minute, and then back to the Youtube video tab, sound keeps playing fine, but as soon as you switch back to the video tab, video actually stays stalled in the last frame before tab switching or simply white, sometimes for just 2 seconds, sometimes for like 7-8 seconds.

Also if you then rightclick the video & choose "Stats for nerds" there's so many dropped frames. Happens 100% of the time.

I see that too for some other ... html5 video sites.
----------------------

(Edit: it's Bug 1262053 - Block playback of media until document is visible)

Html5 videos opened in background tabs do not auto play by default now. Is it an intended change? I don't see any recent fixes related to it. (There was an about:config entry about it iirc?)

STR:
Open a youtube video, or any html5 video, in a background tab.

Before:
Video starts playing in background tab.

Now:
Video does not play right away but it still auto buffers for a bit in the background. It plays immediately when I switch to that tab.

Probably, #1272919 [Core:Audio/Video: Playback]-Video shows the frame that was on screen when I switched from youtube to a different tab for a fraction of a second [Uns]

Bug 1283681 - Enable dom.ipc.cpows.forbid-cpows-in-compat-addons preference
FYI, since 09-22 build some extensions may stop working if dom.ipc.cpows.forbid-cpows-in-compat-addons is defaulted to true.

Context Search X is not working anymore.
Firegestures and Tree Style Tab are in the whitelist. They are still working for now.
