Just ublock origin with default configuration. My complaints aren't for page loading so much as scrolling. Stutter when scrolling is really annoying to me. Interestingly as mentioned the nightly version fixes this, even when ublock is also installed on it.
My occasional page related complaints are for stuff animating correctly. This is very rare and a minor inconvenience usually, but sometimes stops you from being able to do what you came to accomplish (usually on jank websites, rental car companies for example).
Pretending Firefox mobile is already great is counterproductive to fixing it's issues. They don't have extensive development resources particularly for the mobile version so it makes sense it's worse. But to a non-techie switching to it isn't a good experience yet. It definitely can be in the future but without at least acknowledging it's current flaws why would anyone switch who has previously tried switching?
The US really doesn't understand that there is simply no competing with these batteries. To try to block the import of them is only going to set our own local industry back in their ability to compete in the global economy. And ironically the BMS systems for CATL are still using American semiconductors, so the US still gets some revenue from their massive expansion.
The most viable competitors to CATL are all in China too. I'd be somewhat supportive of a CATL specific ban due to their notoriously terrible employee working conditions and crazy NDAs/non-competes, but to ban all Chinese batteries in the US would be a huge mistake.
