Really like this, except that it breaks the Adaptive Tab Bar Colour extension. I’ve been using FF with edgy-arc-fr userchrome and Sidebery which is nearly perfect in terms of UI but definitely feels slower than Zen. I’d definitely switch to this if it had some native adaptive UI colour, I just think it’s neat.
Is the sidebar here just the same as the new native Firefox vertical sidebar, or is it bespoke?
This is an example of a tab group using Sidebery. If you click links on a page that open in new tabs, it creates a sort of folder from the original tab, with the group of links as children of the parent tab. You can also drag them into these groups manually.
