In August we encouraged developers to start preparing their desktop extensions for Firefox Android open availability on addons.mozilla.org (AMO). The project is progressing well and ...
It is irregularly maintained, so I only use it for testing, except for the occasions when it is current.
I really like that you can add any extension, it may not work, but you can try. The bottom nav and toolbar (optional) are great. Pull out tabs, etc. I love the features it has.
In my perfect world, Mull my usual browser, and SCWP would be integrated.
It seems to be a side project for the developer, they also do a webview (smart cookie web) with a lot of nice features and customization.
And they were running their own Searx instance.
They seem to like trying out new features, for instance, they were the first browser I saw that had an 'Amp to HTML' to de-amp links.
