EDIT: Just for completeness sake, here is the command to open Firefox with profile manager and new instances:
firefox --new-instance --ProfileManager %u
https://addons.mozilla.org/en-US/firefox/addon/profile-switc...
You'll need to install a connector for it to work. (The add-on gives instructions during the onboarding process.) Both the add-on and the connector are free and open source (GPLv3).
I use profiles and containers together on Firefox. Each profile has its own set of add-ons, browser settings, and containers. Containers in the same profile share the same add-ons and browser settings. For example, you could have separate personal and work profiles, with containers for different online accounts in each profile.
On Firefox, you have the option of using only profiles, only containers, both profiles and containers, or none of the above.
Anything for that?
If you're trying to create a shortcut to Firefox that launches a profile other than the one you've selected as the default, the instructions for Linux and Windows are here:

This is not necessary to use the profile feature, but some people prefer to launch profiles from shortcuts instead of a menu.
The two final things that would get me off Chrome entirely:
* When I'm using my external USB microphone in a web-based conference system (mostly Cleanfeed but I've also seen it with Streamyard and Jitsi) my audio gets extremely robotic after a few minutes and it somehow impacts my entire system - I have to unplug the microphone to fix it.
* Dropbox, for some reason, hangs at 1 second left when uploading larger files (appx 60MB or so)
Also Firefox hasn't been doing itself any favors by alienating both the average Joe consumers and the professional devs over the years.
Maybe the other commenter is on to something regarding extensions. The only extensions I have are ones to simplify management of containers, plus my password manager.
I wasn't super paying attention at the time, but wasn't that basically how Firefox initially established itself at the expense of Internet Explorer?
Whole process takes a couple years or so.
If everyone thinks negatively, then no change will happen. Keeping reality in perspective is important, but improving things is really important too.

Firefox maker, Mozilla, is in the uneasy position of being financially dependent on its search deal with Google, which accounts for the majority of the organization's revenue.
I wonder how Google will be able to twist its arms (and trust me, they will use all their power and abuse their position to attempt it) to either implement V3 or find some other way to kill ad blockers / allow ads on Firefox.
All I can find is:
We have not yet set a deprecation date for Manifest v2 but expect it to be supported for at least one year after Manifest v3 becomes stable in the release channel.

So they will eventually remove it sooner than later.
