RedirAddon от RedirAddon Team

RedirAddon helps you find Firefox alternatives while browsing the Chrome Web Store. When you visit an extension’s Chrome Web Store page, it searches Firefox Add-ons (AMO) for a matching listing and provides a link when it finds one. If no exact match is found, you can open the AMO search results instead.

This add-on is still under active development. Matching may not work for every extension, and some features may change. Feedback and bug reports are welcome.

To find a match, RedirAddon sends the extension’s name from the Chrome Web Store page to Firefox Add-ons search
