Looking for help here. I created a new Firefox profile and wanted to load the Bypass Paywalls Clean Add-on/Extension from the XPI file. So I did what I've always done and got the message displayed above.
Then I went into about:config and changed both xpinstall.whitelist.required and xpinstall.signatures.required to false. Fully exited and restarted the browser but still, no dice.
Anyone know how to fix this?
SOLUTION: go to extensions.blocklist.enabled and turn it to false
??? None of this has anything to do with anything mozilla runs. Mozilla has nothing to do with me installing an extension from a file. This is like a car manufacturer preventing you from bringing library books into a car you bought.
Except the library book won't record all your conversations in the car and where you go.
Think of how stupid the average user is, and how easy it would be to get them to install any random extension from a malware site.
I genuinely think it's reasonable to prevent users from installing non-mozilla approved extensions unless they go in about:config.
From a safety thing, I get it, and I'm pretty sure you have to enable something to allow you to install extensions from files. This isn't that, this is seperate from that. This is mozilla determining what you are and aren't allowed to add, and that's not ok.
Mozilla is legally required to not facilitate installation of extensions like that, that's why it's blocked
