Like many of you I overuse tabs in Firefox, currently I've about 180 open tabs (my record is ~ 800) and that reduces my productivity since I'm always browsing between them to find the one I need, Closy helps to do some cleaning up but I'm missing a "order tabs by domain" like feature.
What is the less resource hungry extension that provides me such a feature and is compatible with the latest version of Firefox?
Many Thanks in advance!
