Browser miners are most probably CPU miners. Afaik there's no longer profitability in CPU mining, hence it's no use to have any longer browser miners.
Also since browser mining was used to mine on others' computers, many browsers have developed countermeasures, so even if you find one there's quite a chance it won't work.
So yes, the best answer is "none".

PS. Afaik the closest-to-ok CPU mining algo may still be RandomX or whatever Monero has.
PPS. There are also coins advertised as CPU-only (like Hacash) but some are so young you can't sell them so I've considered them as "mining for free". (Keep in mind that for mining one pays for electricity at least).

You can only stand a chance with browser miner if the project is fresh out of the box, meaning new and less difficulty to mine but depending on how good the project is the difficulty can skyrocket in just few days or weeks, not a good way to mine TBH
