@pstein sorry, let me edit here. When you’re speaking of extensions, you are referencing extensions such as what you’d get through Google’s extension store, right? If so, those aren’t available for Android. This was stripped away by Chrome/Chromium long ago and would take a lot of time and money to implement in a way that retains security and privacy.
While there are browsers like Kiwi that can handle extensions, they do this by using greatly outdated versions of Chrome and has a lot of security vulnerabilities.
