I did raise a stink over closed-source DRM, I raised a stink not just over Firefox adding it, I raised a stink over the entire web standards process. I have raised stinks about telemetry and advertising within Firefox. I've raised stinks about Pocket being purchased and not Open Sourced, and then integrated into the browser by default. I've raised stink about a lot of things.
Nevertheless, it is still objectively true that Mozilla Firefox is the best mainstream browser right now for privacy, and anyone who argues otherwise is either not looking at the bigger picture or hasn't done much research into how companies do the majority of their tracking online. The privacy problems that Mozilla has had have objectively less impact on people's everyday privacy than Chromium's hobbled extension support. The ability to turn on anti-fingerprinting features uplifted from Tor is more important than whether or not Google search is enabled by default. Container-extensions are more practically impactful on everyday privacy than Pocket is.
I am literally complaining about and criticizing Mozilla right now, and yet the immediate reaction is to jump on the one positive thing I said and act like I'm somehow ignoring Mozilla's other issues. I'm not ignoring those issues, but the "Mozilla is corrupt and no better than Google" meme is similarly completely ridiculous. Every single other browser on the market including DeGoogled Chromium and Safari are hobbled in ways that make them worse for privacy, and overall Mozilla still as a company has a better track record on fighting for privacy and building privacy-preserving tools than Google/Microsoft/Brave -- at least it has a better track record in the ways that matter.
It is so frustrating to try and have a constructive conversation about real missteps that Mozilla is making when people view anything less than a complete condemnation of the company like that means they're being put on a pedestal. Mozilla isn't perfect, and it's clumsy and sometimes does outright bad stuff, and that is still consistent with them being one of the better corporate privacy advocates on the Internet.
