AFAIK it is clean, but I decided a while back that "better the devil you know"
The potential for negative consequences using a compromised browser or blocking software etc is so huge that I feel leery about using any of 'em - DuckDuckGo, Epic, you name it. The only exception I make is for uBlockOrigin which is not consistent, but hey, otherwise YouTube is unusable. There are always incognito windows, VM and configuration changes that will address specific issues, but then you lose functionality. YMMV, obv.
ETA - Oh yes, additional words need to be added about extensions, which people seem to add willy nilly but actually constitute a huge security risk. Those extensions I have installed (7 total) are all switched off most of the time (except uBlock Origin, as previously mentioned)
EATA - and yes, I was talking generically, but the same holds true on mobile, I use primarily chrome and Firefox as a backup, and live with the shit.
