I’ve got an HTML file on my phone, and would like to view it. But Firefox on Android has neither a menu entry “Open File”, nor does using the file:// method work, nor is any app associated with the .html file extension.
BTW, Chrome suffers from the same problem. And it is not an issue with the file, it works when opened via the https:// method from my home server.
Why, oh why, can’t I open a local file on Android?
The Android way to do this is to open the file from some sort of file browser app and select Firefox from the list of apps that registered for that file type. Unfortunately it looks like Firefox doesn’t register itself for html files.
