While there might not be an addon that perfectly emulates every feature of Toby on Firefox, I am fully confident you can achieve all of its features with settings, config/userchrome edits, or some of the addons that are available. Personally I use Tab Session Manager and Tab Center Reborn (heavily edited though), so you might look into those and see if they have features you like.
I keep people saying they’re missing things from chrome. I honestly don’t get it, if anything I’ve had more usable features since switching back to FF
If you find anything similar to the Toby extension please let me know. I haven’t been able to find anything close on Firefox.

I expect you have tried to search for it in Firefox, but have you tried sideloading it somehow?
As far as I know Firefox supports a superset of the APIs that Chrome support, so it should be a possible?
