I installed the mull browser revently. People who are familiar with this will know that it’s a fork of firefox android. It’s hardened but I haven’t noticed much difference b/w the two. Mull has a few visible tweaks like Https mode by default, strict protection etc. but I haven’t come across other backend/not so visible changes. How is it different from firefox android?
If you dont have differences, great!
Make sure to install Ublock and noscript. Noscript to whitelist javascript for every single website and block the rest, thats the only way to really get privacy.
Also “forget me not” can be used to whitelist cookies, and delete the rest.
