Exactly, but it was just unsuable at the end. When it actually worked with a site, the performance was also very poor. They also not rarely went out of their way to alienate their users and plugin makers and often had the bullheaded attitude that website makers have to fix their websites to work with their gimped browser, as places like youtube would give a shit. Firefox was very shit for a while and pale moon was actually genuinely better, but Firefox is a lot more bearable now and in case people are not aware, you can configure Firefox now to actually use GPU video decoding under X11. And it only took like, what, almost ten years?
