Lol, they chose to ship parts of their browser as extensions, it's definitely now "random extensions".

> and blocking uBlock Origin from working on, for example, the Firefox extension site

Any other example? Bypassing an extension on their own website has absolutely no link to the browser itself being a malware, this is ridiculous.

I don't even use Firefox and I think Mozilla is a shit organization misusing its funds to pursue bad ventures lately, but even I think your claims are bullshit.
