I like Helium as a chromium based browser for PC

When a site just won't cooperate on anything Firefox-based, Vivaldi is my Chromium poison of choice. It also has good privacy features and customization, without the toxic project runners of Brave.

Vivaldi is probably your best choice, but I personally use ungoogled-chromium.

Have a look at Ungoogled Chromium, it's Chromium with all the Google functions removed.

Titanium is a good one. Works with extensions and is updated regularly.

Maybe faking the user agent would help? There are extensions for reporting to sites you are using different browsers.

Alternatively, if you don't want the browser to monitor everything in the PC, maybe install on a virtual machine?

If you really, really need to go down the wrong path, vivaldi is most likely the best choice

brave is gross

open source alternative like fennec and vanadium are likely to be your friends here.

PC - Helium

Android (GrapheneOS) - Vanadium

Android (Other OS) - Titanium
