That might be true for those who are fortunate to have a background in that field, but for the rest of us, Firefox for Android just will not let you install the BPIP on their browser app.
Understanding code doesn't get you on a recommended list at Firefox. Understanding code would allow someone to verify the safety of the extension's source and not lose sleep over a 'warning' and/or 'suggestion' not to use the extension.. but because the previous post labelled this a warning/suggestion, I'd assume it should still offer a way to allow the extension to install.
If it is not letting you install the extension
at all, then coding experience isn't going to really help this. The only way to install it will be if Firefox adds BPIP to their list... or use another browser.
I'd be surprised if the Tor browser app isn't letting the extension install
at all (although may still give a warning), as I had thought they used an older base version of firefox, but I haven't tested the Tor *app* directly myself on an android device (and I don't currently have an android device to test!..).
Anyhow, any further discussion relating directly to the extension should probably be moved over to the
BPIP extension thread!
