Two years has gone by with no changes to Mudcat Browser Tools (MBT). It has about 14 average daily users on Firefox and 6 on Chrome (or Chrome-based browsers). For the first time Android users are a clear majority (of Firefox users), which is perhaps due to the decline in consumer desktops compared with mobile devices.
Up until recently Firefox for Android was the only browser that ran addons on mobile. But I have discovered Orion Browser, which runs on iPads and iPhones and supports many addons including mine. I tried it on my iPhone and it works. So if you regularly read Mudcat on an iPad or iPhone you could try it, and the features I listed in the first post in this thread.
I originally wrote the scripts that became MBT to make Mudcat easier to use on a small tablet, and some of those features, such as rearranging the layout and making the posts' font bigger, are not enabled by default. You enable them in the 'Extensions' menu item: long-tap MBT to get the Options page. You must tap 'Save' at the bottom afterwards.
