Waiting for Vertical tabs in Firefox? Official Nightly builds now offer this feature, allowing you to enable and even move it to right side.
The most requested Vertical Tabs will make an appearance in the upcoming Firefox. The feature can now be turned on in Nightly itself without the need to rely on third-party extensions or separate Nightly builds.
Currently using Sidebar Tabs. I have gotten used to grouped tabs, which is something I don't want to give up. I've mapped Ctrl+Space to open and close it, which is super satisfying.
I switched from Sideberry, which was cool since it is so configurable, and that it can store and recall entire lists of links. I think this is a nice alternative to bookmarks, because it gives you a sort of link manifest, that you can even export.
Mozilla's attempt seems... lackluster in comparison, but it's still under development. So eh. Thinking of going Librefox, Waterfox or even Floorp - though that would be like going ESR.
or even Floorp - though that would be like going ESR.
...but in July, the #Floorp Dev is jumping from #ESR to FF-Release version. Really looking fwd to it. Already Floorp + #Sidebery is wonderful, so soon will be even better.
