No, you are not. You are a Google marketing tool.
And this is not ad-hominem from my side, since you made a claim about yourself the main part of your argument.
Google is known for intentionally crippling Firefox performance on their services. That doesn't make Firefox itself slower.
Unfortunately the Firefox codebase itself is the only marketing tool at work here. I still use Firefox for everything else, not least due to the fact it isn't trying to swindle every last private detail out of me, but for work stuff and gaming (O365/GCloud) I don't really care about any of that.
Hiding behind lies and random personal attacks will not make Firefox better, but comparisons to its main competitor in key areas might help
