I work on a firefox addon using JPM.
I want to install it on my android phone, i\'ve run \"jpm xpi\" and copy xpi on my sdcard. When i browse to file://path/to/my/xpi in
Neither ES File Explorer nor X-plore worked for me (as per Trasd's comment). I saw the three Firefox's, but none of them triggered to install the XPI.
The solution for me was creating an installer HTML file in the same directory as the .xpi
files, like the following.
install.html:
ABP
FVD
Then, you can either:
file:///storage/sdcard0/MyXPIFiles/install.html
In Firefox viewing the install.html
file you created, click on each link on the page, and you should see a prompt, "Firefox prevented this add-on from installing on your device." Just click "Allow", and it should install.
EDIT: Apologies, I see you said that navigating to a URL did not work for you. But if no one minds, I'll leave my answer here, cause it's the only one that worked for me, and maybe others too.
