I have multiple devices. This extension in general is a bit buggy but gets the job done with some tweaks.

Linux Firefox/Brave, Windows Brave: The hidden tab cannot be disabled.
Windows Firefox: The base version of Firefox keeps crashing. But it works on a separate portable version of firefox from portableapps.

It's far from perfect, but it gets the job done. I am at least glad I am not forced to use MS Edge for the same features.

Get some duplicates, but still very useful for work with multiple websites
Allow me to organize those websites in "spaces" so i can focus only on the pages im working on

I love the fact of having different concrete and distinct spaces. This allows me to smoothly transition from one state to another, while allowing me to be very focused when I am in one space.

There are still some bugs that needs to be fixed, and some initial struggles with working together with persistent pins. But once I fixed it, I've loved using this extension since.

A very useful way to keep track of lots of tabs without overloading your browser. I've found a few times when tabs have just disappeared so I've started adding then as Resources which will hopefully keep them safe. Pinned tabs are also not recognised for some reason. Just today after a Firefox restart Workona wouldn't work so I had to remove tje add-on, then re-apply it. I feared I was going to loose tabs but all was OK.

I would prefer not opening up of all tabs when I click on a section but prefer it opening up in the workona tab because sometimes you just want to move tabs to another section and don't want to be blasted by all the saved tabs also the undo toast message at the bottom right can be replaced to some other part of the screen as it annoys from moving and organizing tabs.
