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
That doesn’t at all look like what’s happening in the above image. It obviously isn’t being installed from addons.mozilla.org because they wouldn’t be hosting it. And the pop-up says it can’t be installed because it “violates Mozilla’s policies” not due to security issues or because it’s not from their extensions gallery.
Yeah, it can technically be served from a button in another website, but it has to go through mozilla for firefox to accept to install it, I did misspeak in my original comment.
