Firefox for Android Support Forum

Hi, how can I open a local html file with firefox 86 on android 9? It's like firefox no longer registers itself as a valid program/association to open html files.

What I've tried so far: 1) If I type file:/// in the URL bar, nothing happens. It works on Opera. 2) If I go to a file manager, select an html file, and click "Open with", firefox doesn't show up; Chrome and Opera do. 3) If I go to the android settings > applications > firefox > associations, firefox shows no associated file types at all.

The HTML language isn't only used on the Internet, it's also used for local documents, please allow us to use firefox to view our local html files.

Hi everyone!

How can I restore a previous version of Firefox on my Galaxy J4+? I tried to follow instructions that started with "in search box type: about:preferences#advanced". That didn't work.

I also opened http://ftp.mozilla.org/pub/firefox/releases/83.0/win32/ I don't know which version I had before this one, in which the search bar is at the bottom. I just figured 83 was far back enough! But the .exe file I downloaded could no be opened by my phone.

Below is the current version: (I hate this version. So sad. Firefox was excellent. But if I can restore a previous version, that would be great.) 86.1.1 (Build #2015794881) AC: 72.0.16, f4aa67a9c GV: 86.0-20210222142601 AS: 67.2.0

Thank you for your help!!! Mabel
