Alternative WebExtensions for Firefox Quantum

With Firefox 57 a lot of legacy extensions stopped working (see the list Discontinued Legacy Addons for Firefox ). Luckily some developers created new WebExtensions as replacement of these popular addons, trying to restore all their functionalities in spite of WebExtensions API limitations. This a list about the most interesting ones I have found.

  1. Foxy Gestures implements mouse gestures for Firefox and is inspired by FireGestures icon FireGestures . Unfortunately, there are many limitations due to limited or absent Web Extension APIs: extension cannot integrate into about:newtab, about:home, view-source:, etc. Nor will it work on addons.mozilla.com

    Implement any command with user scripts.
  2. Copy PlainText, as suggested by the name, is a replacement for Copy Plain Text icon Copy Plain Text and Copy Plain Text 2 icon Copy Plain Text 2 . It is Multi Process compatible and offers 2 keyboard shortcuts: F7 and the original Ctrl+Shift+F7. Anyway user can't define his own keyboard shorts and Copy PlainText can't be set as the default copy function of the browser.

  3. Self Destroying Cookies is a WebExtension clone of Self-Destructing Cookies icon Self-Destructing Cookies : it automatically removes cookies, after the tab closes or you leave the website, but it's not yet able to clear the LocalStorage, due to API limited access.

  5. Conex icon
     Like

    Conex is a replacement for the discontinued Tab Groups icon Tab Groups : it implements groups via containers and integrates a search function for tabs, bookmarks and browser history. At the moment hiding and showing tabs (one of the core features) is blocked by API limitations.
