It still is way slower than any chromium based browser, lacks features that have been standard on chromium for years

I don’t think its slower at all. Most of the time same if not faster. Maybe it depends on where you go?

Features in chromium are often there because they are going their own way and not being standard, is that Mozillas fault?

HDR video is in Firefox, HDR images is experimental. Personally I don’t care, why would I watch videos in a browser that I think should have HDR?

I will agree that Mistral should have done the lifting, and Firefox need not be working so hard on adding AI. However, if they don’t people on the other side of the fence will complain that Chrome gets all the AI, why is Firefox so lazy?
