Extension is minimalist and excise. Buffer seem to be ignorant about further development. E.g. current integrations to sites ignore new social medias on the market, like BlueSky, various fediverse sites. Also, no integrations for LinkedIn suggests it doesn't think of business use. With Buffer's own deficiencies, like underdeveloped 'idea' item kanban concept and lack of price offer for small businesses, it makes overall experience mediocre, requiring more effort than done.

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.
