I have three recurring bugs, and they're ones reported by other users. Firstly, the tab sidebar often doesn't load and just shows the loading indicator forever. Secondly, it can get into a mood where clicking one tab switches to a completely different tab (often the tab directly before it in the tab order) (clicking the tab in Firefox's default top tab bar instead works as expected, so the issue is definitely with this add-on). Thirdly, it often forgets and rearranges child tabs with no apparent logic, changing the order and hierarchy completely.

I rely heavily on this add-on so I'm hoping they can fix these issues. It would be an easy five stars if I could just trust it without worrying whether or not it'll even load! I want to remove the default tab bar and just use this add-on, but at present I can't trust the add-on to work properly.
