All the issues have been fixed! Flat out, this extension is the main reason why I use Firefox, I can't stand Tabs on top; they are a mess when there are more then 3 open tabs! No other browser handles tabs on the side well. Chrome's similar extensions are all horrible. Edge and Vivaldi don't handle "tab children" the same way and you can't tell what tab a new tab is from if you do "Open in new Tab".

And then add in all the other addon Extensions that Piro has made for TST, it can't be beat.

I utterly fail to see why this sort of thing isn't just an option for ALL browsers. I guess it just shows how technical of user I and others that need something like TST are.
