Mudcat Browser Tools will now run on Android (again).

As I wrote in my OP, in 2016, the add-on originated as tools to make Mudcat more readable on a small tablet. Some of the features were aimed at very small screens. Firefox's Android browser removed support for all but 'recommended' add-ons in 2020.

Mozilla has now restored the ability to run any add-on in Firefox for Android, so Mudcat Browser Tools is available again.

The default features are the same on desktop and mobile, but if you use a very small screen you might investigate the options to reororganise the index page, and use a bigger font for posts. There are screenshots of it on a phone on the Firefox add-on page

Chrome never supported extensions on mobile. You can of course install Firefox on Android just to read Mudcat while keeping Chrome as you default browser.

A note about Mudcat URLs.

For historical reasons, you can run Mudcat using different URLs:
- https (secure) or http (insecure)
- mudcat.org or www.mudcat.org

If you just type 'mudcat.org' you might get the secure version or the insecure one, depending on how your browser is set up and how the server reacts that day.

In order for Mudcat Browser Tools to work, you must stick to to the same type of URL and not mix http and https, or mix URLs with and without www.

I recommend that you always start mudcat from a bookmark (favourite) that starts https://mudcat.org. Revisit any old bookmarks and ensure they all use that format.
