That has been the best solution so far for vertical tabs but grouping needs some work.

but to be clear it is not great compared to edge.

Edge's vertical tabs and grouping. Every solution on Firefox feels half-baked.

Really, the only option. Either more pay or more free time. The amount of savings in not having to commute means going back to the office is a pay cut.

Will look into it. Thanks.

I really hope Microsoft sees the light. Edge is the best browser for my productivity. Can't work without their implementation of vertical tabs and tab groups.

Every so often I try it out on firefox and any option is just still not ideal.
