This was made particularly clear to me when I tried to install AdNauseam [1] on Chrome. Google removed the extension from their web store (imagine doing something the user wants, like messing with Google ads, terrible!) so you have to sideload it via the developer options. Now I get a popup every time I open Chrome telling me that there's a dangerous extension with a single click uninstall button.
Firefox has its issues (the signing requirements because of malware and invasive antivirus companies suck but I can understand why they exist) but their addons aren't discriminated against. There's addons listing porn sites on there, something for which Google would remove the extension on sight, there's addons that mess with Google and their ads, and the list goes on. The browser is no longer independent from Mozilla, but it still remains much more free than Chrome.

On chrome you can actually create your own signing key, and then self sign the unpacked extension directory using your key. To remove the pop-up you then need to set up a group policy (on Windows) to trust your self signed extensions. End result is this popup doesn't come up at launch.
I think this is so hidden (and not really documented well) as a "fix" that must have been added for companies that use their own internal extensions that don't publish them on the web store.
If you can't figure it out from that description I can try to publish a step-by-step on how to accomplish this
