This is AWBfL ("Andy's Webkit Browser for Linux"), a GTK3 and Webkit2 based browser written in Vala
AWBfL is pronounced "awbful", rhymes with "awful". I'm not a marketing person.
It is a fork from the original Midori project at github
Various old PR's have been integrated, some buggy tab history repaired, and it doesn't always switch to the first tab on any tab close.
It has an extension to do username/password saving. It also has an external command to sync user/pass completion, and a sync server which is trivial to run. Passwords are encrypted before being stored on the sync server, so only your own browser installs can use them. (The sync process is UDP based.)
It also has an option for the right-click menu on a link to open with JavaScript disabled. 99% of new pages I visit are better viewed this way.
Join the fun! The dev is @vandys@goto.vsta.org on the Fediverse. We'll use chat/forum/wiki here on this site unless they have some fatal flaw.

Until I can find the original dev, I'll try and put up a basic home at: AWBfL Home Page
Speaking of the original dev--if Christian Dywan reads this, we'd love to talk with you! Please get in touch.
