A firefox extension that allows you to search and auto filter similar tabs to the active one in a fast and smart approach.
You can get it from here: https://addons.mozilla.org/firefox/addon/tab-fx/
See it on action, here: https://youtu.be/o0TLDZKxJIU
Or check the next articles to find out more about the extension:
Full support is expected in 2025-Q2.
For users that would like to experiment on Chromium based brwosers, I published (as unlisted) an adapted version of the Firefox one in the Chrome Web Store: https://chromewebstore.google.com/detail/tabfx/dpceadjahgnbmmlhfdiaecpgaadpacab. Feel free to install it although I can't guarantee the same support as in Firefox for the time being.
