dimdenGD/OldTwitter

Browser extension to return old Twitter layout from 2015 (and option to use 2018 design).
This extension doesn't add any CSS on top of original Twitter. It's fully original client that replaces Twitter, making it much faster than alternatives.

Chrome, Edge, Opera, Brave & Chromium browsers: Chrome Web Store
Firefox: Addons For Firefox was removed, install manually from Github

For beta version:

• You need Github account, please register if you haven't first!
• Go to Actions page
• Click on latest "Pack Extension" workflow run (first from top)
• Download OldTwitterChrome if you're on Chromium based browsers and OldTwitterFirefox if you're on Firefox

For stable version:

• Go to Releases page
• Download OldTwitterChrome.zip if you're on Chromium based browsers and OldTwitterFirefox.zip if you're on Firefox

• Unpack file anywhere
• Go to chrome://extensions
• Turn on Developer mode
• Press "Load unpacked" and select folder with extension
  

• Go to about:debugging#/runtime/this-firefox
• Press "Load Temporary Add-on" and select zip file you downloaded

Installing this way on Firefox will remove it after closing browser. You need to use Firefox Developer Edition instead for permament installation (see below).

• Go to about:config
• Set xpinstall.signatures.required to false
• Go to about:addons
• Press "Install Add-on From File" and select zip file you downloaded

This reportedly works with Firefox Extended Support Release and Nightly as well.

Yes, you can use Kiwi Browser to install it from Chrome Web Store or Firefox Beta/Nightly to install it from Addons For Firefox (follow these steps for Firefox). Once installed you can press on "Add to Home screen" button in Kiwi Browser to have it as standalone app.

The source code is available at GitHub so you can check everything yourself. It never sends any of your personal info anywhere.

Extension won't be pixel perfect copy of old Twitter. I just took general look and feel of it.

You had algorithmical timeline enabled. By default OldTwitter turns on reverse chronological timeline, you can switch it back to algorithmical timeline in settings or using the switch on the right side.

You need to add ?newtwitter=true to end of your current URL. There's also a "Open this page in new Twitter" button on all pages on bottom right.

Click on your profile picture on top-right and then Settings button.

There's a setting to use design from 2018.

You can disable all hotkeys in settings.
