Return YouTube UI

An extension making YouTube look like it did before everything was given rounded corners.

Supported Browsers

• Firefox
  • Main priority
  • Every version will be compatible with the latest version of Firefox at publish time
• Chromium-based browsers
  • Lesser priority, dedicated parity updates
  • Most functionality tested with Brave

Due to diverging implementations of V3 manifests between Mozilla and Google, to work with Chromium-based browsers instead of Firefox, you must switch the commented lines in manifest.json.
manifest.json

"background": {
  "scripts": ["background/background.js"]//for Firefox
//    "service_worker": "background/background.js"//for Chromium-based
},

Major releases are published to the Firefox Add-Ons page as an extension (addons.mozilla.org/...) and will continue to receive new updates. To install another version or your own fork, visit firefox-source-docs.mozilla.org/... for instructions (or just enter about:debugging#/runtime/this-firefox) into your url-bar.

Settings & Customization Flags

Settings control has been migrated to the extension popup page. With the latest versions, some settings have been moved while others are still only available to be set as static variables before installation. Those values can be adjusted by setting flags at the very top of "triggerSetup.js".

Items that are the core principles of return are on by default
