Just a shout out to https://github.com/mbnuqw/sidebery. My favorite productivity extension. I'm a tab hoarder, this makes my life manageable and gives my Firefox all the screen real estate by using keyboard shortcuts to open/close the tabs easily.

I also use the Firefox css to hide the top sidebar, so I get maximum screen usage.

Their bookmark feature is pretty awesome too.

I'd also add Winger to the list, it makes it easy to group tabs by window and move them between windows.

With Sidebery, you don’t need to use multiple windows (which are a PITA). Instead, you use panels which are always visible and easy to switch

Thank you! I just learned I don‘t need Arc to achieve this
