this should be a recommended Firefox add-on

It's perfect, I was waiting for containers to implement history separation when I remembered profiles existed.. this simplifies using them a lot. I can only suggest a setting to set the default profile (and maybe automate this based on the last closed window profile).

Pretty UI

Should be included in the default Firefox configuration!

makes switching between profiles so much faster and easier

Wow! Click! Click! Install! Works like a charm! 5 starts! Thank you!

This profile switcher works great and has a nice UI!

Algo que debió haber existido hace rato, muchas gracias

Awesome Add-on!

Well done, please keep up the support of the extension in the future.
