The installation of Firefox I had issues with was in like 2016, and it was up-to-date at the time. I'd tried Vivalidi since it was an offshoot of Opera, for that exact reason - at that time, I didn't have my own full VPN (now I do).

I'm looking at Brave's site though. They've got some pretty interesting information - especially for the mobile version. While bandwidth isn't a huge issue for me because I'm largely homebound and on wi-fi, anything to make downloading faster is appealing - and having something cutting down on data does that.

Thanks!
