After the update Firefox 25 tabs "will return" 2 to 3 pages, when switching tab or exit full-screen.

It happens more frequently when you exit the full screen of a video. for example, youtube, dailymotion, nbc.com - the entire site with embedded video players.

When you exit the full screen, the page goes back 2-3 pages. And no, I'm not clicking on videos related everything fullscreen all the time: that's all by launching full-screen and full-screen, all on the same page of output video.

This happens less frequently during the passage of the tabs - but if I switch to another tab, then return, the first tab will load the page that I've been there are 2 pages.

More information: when this happens, the "arrow" is grayed out and the page that loads is on the list of the "arrow" twice - lower in the list where it should be, as well as the top of the list, as if I had clicked on a link to this page.

All this started immediately after restart Firefox after updating to version 25 - no other changes have been made to my computer.

The problems were with HTML5

Subject: config > media.webm.enabled > false

Problem solved! BY ME!

(Attached picture is a screen CAP that shows up if HTML5 is disabled. I had noticed before the update of Firefox, but it was never enough to the top of long to actually read, and I didn't really like. When she returned immediately after the deactivation of HTML5, I did a screen CAP to see what has increased. Oh I see... something worked, so some fool decided to fix it... Genius!)
