Thank you so much! This is a feature that i really missed from Arc. It works very well and I like how minimal it is and that I can use the shift click shortcut

Very cool options here ::)
One more for me...
an option to open juste one popup/window (named ?).
1. I open an new popup (by shift+clicking for exemple)
2. I re do a shift+clicking
3. The last link I click (2.) go into the first popup (1.)

Hey, this is wonderful and it's also the only thing I can find that has the function on Firefox which mimics "Open as Pop-up" from Chrome.

The only issue I'm having is that the context menu "Open Page in Main Window" never seems to work. The pop-up window stays and clicking that option does nothing. In case it's relevant, my use-case here is that I like pop-up windows as semi-permanent ways to display some windows on my screen in a clean, clutter-less fashion to keep my interactions with these windows as focused and clean as possible.

If you have any suggestions for how I can make the option to reopen the page in main window work correctly, I'd really appreciate it!
