My "browser stack" is based around Microsoft Edge.<p>- Vertical tabs are native and function perfectly.<p>- It sleeps inactive tabs to save RAM.<p>- It has the Workspaces [1] feature, basically creating cloud-saved tab groups. This only works when your account is tied to Azure for now (so only at work), but that's the only time I use it, so it's all good. Tons of extensions try to do this, but it's nice not to have to use one.<p>- This hidden gem of a browser extension: Auto-Group Tabs [2]. Lots of extensions claim to do this, few do it well. It supports regex and pops tabs into groups extremely quickly/smoothly. It feels native. Combined with the vertical tabs feature, you get nice, easy to read, collapsable groups. The developer is super responsive and awesome.<p>Honorable mention extensions I've tried but ultimately don't use anymore:<p>- Tab Xpert [3] It's a full-featured tab session manager, one of the better ones I've tried. Very stable with an active, very responsive developer. Probably great for some people, but I don't end up having so so many tabs that I find it necessary.<p>- Clutter Free [4] Keeps you from opening more than one of the same URL. Would be really useful, but I found it too disruptive to use daily. You don't realize how many SPAs with single URLs there are until you start using something like that.<p>I also recently got access to Arc Browser [5]. It seems great and I like a lot of the design decisions. Haven't moved over to using it by default yet though.<p>[1] <a href="https://techcommunity.microsoft.com/t5/discussions/introducing-workspaces-in-edge-new-feature/td-p/2263507" rel="nofollow">https://techcommunity.microsoft.com/t5/discussions/introduci...</a><p>[2] <a href="https://chrome.google.com/webstore/detail/auto-group-tabs/danncghahncanipdoajmakdbeaophenb?hl=en" rel="nofollow">https://chrome.google.com/webstore/detail/auto-group-tabs/da...</a><p>[3] <a href="https://tabxpert.com/" rel="nofollow">https://tabxpert.com/</a><p>[4] <a href="https://chrome.google.com/webstore/detail/clutter-free-prevent-dupl/iipjdmnoigaobkamfhnojmglcdbnfaaf" rel="nofollow">https://chrome.google.com/webstore/detail/clutter-free-preve...</a><p>[5] <a href="https://arc.net/" rel="nofollow">https://arc.net/</a>
