Hi! With all the stuff going on I want to switch to Firefox. I got incredibly used to the sidebar in Opera Though and really want something similar.

E.g. Having WhatsApp in the side tab and not in the header tabs (so I can’t close it accidently) or different t workspaces for different projects has proven incredibly helpful. Also on opera I can open 2 Windows with the same workspace and get different tabs making it really useful for programming.

I’ve looked around for plugin like that but could only find one where the tabs were also shown on the side and the top.

If anyone could help me here that would be great, I am really on the fence of switching to way land and ff on my machine.
