I REALLY this to work on pro.x. com...formerly tweetdeck

Heads up I was stuck on 3.3.x even though I had auto-updates on. Had to manually update to 3.4.2 which installed as a separate extension rather than replacing the old one.
Overlay still opens in a new tab, but at least I am current.
As others have said the Chrome extension is much more polished/feature rich, and it would be great to see the FF extension get the attention it deserves, particularly with `Quantum` released and now v60.

This plugin leaves much desired than the Chrome one. First of all, why is there not an overlay but a new tab when sharing content? It is really annoying

I was looking for an addon that will force videos to buffer when paused, and that isn't limited specifically to youtube videos. This app got my hopes up, but wasn't what I was looking for. (it turns out that what I was looking for may be impossible)

update: yeah, sorry for the bad review, I was feeling kind of crummy that day. Updated to a neutral 3 stars and replaced snide section of my review with something more reasonable. I don't really use social media so I'm not really in a position to rate this addon. Hopefully those who do will find it useful.
