What's the best browser in browser proxy for secure and private browsing? or How reliable is a browse

"Does a browser in browser proxy actually protect your privacy?"

Hey guys, been hearing a lot about browser in browser proxy tools lately. Some say they’re great for privacy, others call ‘em sketchy.

So like… does a browser in browser proxy *really* hide your stuff? Or is it just a fancy way to get blocked by sites? I’ve tried a couple, but idk if they’re actually secure or just *feel* safer.

Also, do they log your data? Cuz that’d be ironic lol.

Anybody got real experience with these? Or am I better off sticking to VPNs?

Thanks!
