I read the reviews and know why it does not work. Thanks for doing this when this was still possible.

Update pls...

Doesn't seem to work, even after refreshing a dozen times. Please release update for June 2020.

I've been using your addons for a while! it works great but twitter changed it could you please fix it?

From May of 2020 not woking anymore.

Thanks for all the good times... Doesn't work as of just now. Says browser isn't supported. Now we're waiting for youtube to stop working aswell. Don't get their need to push their shitty ass designs when old ones were perfect. Doesn't help they're so god damn ugly too.

Beautiful, thank you very much! Awesome web-ext, it brings back the old Twitter interface which is what we needed, omg! Bah, can't thank you enough!! :))

Tested similar add-ons and found out this is the only one that actually works. Copy & Paste works although you can't use CTRL-V for pasting images. Use right-click's paste function instead.

Thanks Wolvan.

Edit:
Unfortunately video's do not show up.
Also try add-on Twitter Old UI

This extension works and keeps all videos (even under one minute) from lopping/repeating automatically. I LOATHED THAT (especailly with under one minute ones).

It does, in fact, bring the Old Twitter Layout back. It claims that Paste function has been restored, but it hasn't, hence 3 stars.

This add-on (and a similar) appear to work well, but have one big problem. They prevent embedded videos in some Twitter posts from being viewable. If the add-on is disabled, they work. The symptoms are: (1) the static image for the video flashes very briefly on the screen, but (2) then I get a gray player box saying "We cannot play the video in the browser. Try another web browser."

Here is an example: https://twitter.com/GreenRupertRead/status/1182979393666375680.

In Web Developer | Web Console, I get this further explanation:
<>
Cannot play media. No decoders for requested formats: video/mp4; codecs="avc1.42E01E mp4a.40.2", video/quicktime; codecs="avc1.42E01E mp4a.40.2", video/x-m4v; codecs="avc1.42E01E mp4a.40.2", application/x-mpegURL, video/mp4; codecs="avc1.42E01E mp4a.40.2"
<>

I hope you can find a way to fix this. (It's the only reason I didn't give it 5 stars.)

Works great.
Thank you!

doesn't work anymore by 2019 09 09.

Thanks for this. If anyone is having issues with copy and paste I suggest you highlight text in another browser window and then pick it up with mouse and drag it over an open tweet box. Enjoy!
