@[email protected] Cool. Interested to hear later what you think of it.

@[email protected] @[email protected] Yes...

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.

@[email protected] @[email protected] Agree, but fwiw, IMO, #Sidebery is even more powerful & flexible than #TreeStyleTab AO. After being spoiled by both these for years, #Nightly has heaps of catching up to do before the native solution will become my choice... but i emphatically DO want sophisticated #VerticalTabs to be native, so hope the Devs learn from & adopt from these two AOs.
