Hello. I am a Firefox user, and everyone I know tells me that using Firefox on Android is not secure. What are they basing this claim on? I have tried using Chrome, but I always go back to Firefox because it is the only open-source browser that allows me to pin favourites to the home page and because the display of websites adapts very well to the chosen size. Which FOSS browser derived from Chromium allows you to choose your favourite websites on the home page?


Chromium based browsers are more secure. Here is a detailed breakdown https://madaidans-insecurities.github.io/firefox-chromium.html#sandboxing
The article lists “less granular process model, weaker sandboxing and lack of modern exploit mitigations” as the security drawbacks of firefox
They used to not have sandboxing for each tab. The app was sandboxed but all tabs had access to one another but that was fixed few years ago. Not sure about others
