@nekohayo Sigh.

Firefox's reputation is in ashes

Only in the minds of peeps more influenced by #FUD than facts.

tab workspaces (a.k.a. tab groups

Workspaces are not the same as tab groups. #FirefoxNightly has had viable native #TabGroups now for several weeks [for both H & V tab arrangements], but still has no #Workspaces. If you want actual proper literal Workspaces, you need to use any of Vivaldi, #Floorp, or #ZenBrowser. However, be aware:

• Zen is only based on FF 136, so unlike Nightly, atm does NOT have properly working Tab Groups.
• Floorp 11 is based on FF ESR, so uses its own in-house #VerticalTabs, & has no tab groups [but good Workspaces]
• Floorp 12 is atm in Beta, is based on FF 136, so does have FF's native vertical tabs, but like Zen, atm its Tab Groups are very broken [like they also once were in Nightly, but now are good, so eventually they will also come good here]. It does have Workspaces already, but atm they & many other features in this early Beta are not working properly.

@levi #VerticalTabs are functional in vanilla , but less polished than atm in . #TabGroups atm are badly broken in for Vertical, but work ok for Horizontal tabs... otoh TabGroups are working quite well [but still not perfect] for Vertical tabs in .

An advantage that & have over stock & is #WebPanels & #SplitTabView. However, there is a wonderful project called #FirefoxSecondSidebar https://github.com/aminought/firefox-second-sidebar that gives the Foxes a WP UX superior to those two FF forks & also Vivaldi. Furthermore, it can also be used as a defacto Two-Tab-Vertical-Split-View. For these reasons, i lost interest in both & , & happily use:

#FirefoxNightly + #Sidebery + #uBlockOrigin + #FirefoxSecondSidebar =
#FirefoxNightly + #NativeVerticalTabs + #uBlockOrigin + #FirefoxSecondSidebar =

@Flaky The entire point of it, IS for #webpanels. It works brilliantly, & is so good that i was able to dump both #Floorp & #Zen & return to #Nightly, with FSS installed in it, & then in FSS i have 18 frequently-used sites, & one AddOn, as dedicated WPs. Til earlier today i actually had 3 AOs in the FSS, but chose to move 2 of them back to the normal FF toolbar at the top.

I have one profile with FSS & #Sidebery, & another profile with FSS & Nightly's native #VerticalTabs & #TabGroups. They both work very well.

#FirefoxNightly + #Sidebery + #uBlockOrigin + #FirefoxSecondSidebar =

@OpenSauce It depends. My abuts my virtual desktop's RHS vertical Plasma panel, & extends toward the LHS but leaves a 390px column of exposed desktop wallpaper. That space is filled with my several #Conky 's, so i can keep an eye on what my system is getting up to whilst i happily browserise. When i am watching a video, i position its #PiP windowlet at the bottom LHS corner of my screen & widen it until it touches not merely the browser window's LHS edge, but overlaps it & also covers that lower portion of the #VerticalTabs column, stopping at the vertical interface of said column & the browser website page itself. If i used the VTs on the RHS, i would have to reduce the PiP windowlet to be only 390px, instead of the pleasant 645px now. So, horses for courses.

@countablenewt Teehee

Nightly ofc does not have split tabs, but another benefit of my having begun using this mod is that i suddenly realised last week [i'm a dimwit, slow learner] that not all my WebPanels need to be "permanent", some can be temporary, meaning than i can use this as my workaround two-tab split-tab view, then delete said panel once i'm done with it. I'm really loving it... + ofc Sidebery is so much more powerful than the native #VerticalTabs of , , & . With this panel, i no longer feel that by moving back to from that i'm missing out on any functionality of importance to me [ie, i agree that both Floorp & Zen have many excellent "extras", but the only two i truly care about are WebPanels & SplitTabs]. Anyway, fwiw.

@Stanisable @FirefoxNightly Because they are non-hierarchical, untreed, they are no replacement for my beloved #Sidebery, but i agree the recent improvements of them in is commendable, not least their fix two days ago of group collapsing/expanding.

@vyskocilm Aha!

groups can be collapsed & expanded, that function is broken in vertical tabs

#FirefoxNightly gets updates 2x/day. The 2nd one today fixed this, so now the groups do behave well in #VerticalTabs

@vyskocilm It doesn't have tree structure as you said, but also, whilst in horizontal mode the tab groups can be collapsed & expanded, that function is broken in vertical tabs. Furthermore, in vertical [my preference, as a longtime TST --> #Sidebery user] guise, the vertical padding between tabs is ginormous, such that only a small number of tabs fully consumes the column height & triggers the scroll bar, whereas in Sidebery the same tabs occupy a fraction of the space. There's so many other problems & omissions as well. The Devs have a long long way to go before their native VTs will ever viably replace my Sidebery.

Btw, i use #FirefoxNightly, whose #VerticalTabs deployment is slightly more advanced than in vanilla .

@danirod I use #ZenBrowser [several months], but with various profiles. My main profile uses #Sidebery, not the native #VerticalTabs & #Workspaces. One of my other profiles does use all the native features & no Sidebery, but though i frequently try it, atm it's still too primitive for my tastes compared to the power of Sidebery. Fwiw, in that other profile, i have occasionally experienced what you described, & iirc various peeps have mentioned it in subreddit posts.

@mzeinali Fwiw, i've been monitoring their progress for months, in my #FirefoxNightly. It's still extremely primitive, & barely functional. The tab groups are merely single-tier [ie, there is no nesting nor tree structure], & though they now can be collapsed in the horizontal tabs bar, once you switch to the #VerticalTabs bar the collapse function fails. They are still so far behind the sophistication of #TreeStyleTab & especially #Sidebery AOs that i fear they'll never catch up... meaning this long-missing native function/feature will never become viable for me.

Atm my hopes are slenderly vested in #ZenBrowser whose Dev @zenbrowser months ago promised that fully nested native tree tabs were on their development path [https://l.opnxng.com/r/zen_browser/comments/1eqqzlt/the_one_feature_that_will_win_me_over/lhv19c4/?context=3#lhv19c4]. Until then, in all my Foxes, it remains #Sidebery all the way.

@fatboy Pity imo that the new tab groups still can't yet be collapsed in #VerticalTabs, only horizontal.
