> However, I hate using tabs in the browser, so thanks to a hacky extension, firefox opens a new window per tab, which means that i3 manages firefox' tabs as regular windows.
Can you provide a bit more information about your setup?
I'm using sway and I removed the tabs from Firefox to handle them as individual windows.
I don't have my machine on hand to give you the specific extension, but basically it's something called "notabs" or similar. Whenever a new tab is opened, it gets moved to a separate window. It works mostly OK, but it can sometimes get confused.
I combine this with some custom chrome to completely hide the tab bar area at all times.
Afterwards, I manage my firefox windows with i3 as I would any other window. They usually end up in tiled mode.
