Gifs in tabs start playing?
Yesterday I bit the bullet and updated Firefox from 18 to the current version (25.0.1). The first thing I've noticed is that when I open new tabs (just open, not focus on them), the gifs in said tabs load and already start playing, even though I haven't visited that tab yet. I then come to the tab and to a gif in mid-animation. On my older version the gifs loaded and then waited until you actually went to the tab before they started playing. I don't see anyone else complaining about this.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
Do NOT click the Reset button on the Safe Mode start window.

Go to the Mozilla Add-ons Web Page and see if anything there looks good to you. The add-on I use is; Flashblock.
Safe mode doesn't help; it's already in the default theme. Gifs still start on unfocused tabs.
Serves me right for updating. FF updates and me are like an abusive relationship; they fuck me up each time, yet I'm still a dumbshit and go back to them. Now it also started to sometimes (rarely, but happens) go to my homepage when I click refresh on random webpages, and removing all the "Back" button options when doing so. It also handles multiple tabs way worse than 18, and 18 handled them worse than 12 or 13, which I had before that. Also I see that ESC no longer pauses gifs - genius "feature". Some sites also don't display until I refreshed them twice, saying there's been an encoding error the first time, but after a refresh it's all good. Every new update makes it worse. SO glad I updated.

This is bugging me as well. I previously used an older version of Opera (12) where .gifs likewise didn't load before actually being viewed, and it's annoying that this feature seems to be absent in Firefox. Ironically it also appears to have been removed in newer Opera versions. If anyone could come up with some sort of configuration option or system tweak that could fix this I'd be most grateful.
