I started this project a few weeks ago for my transition from Firefox to Falkon, and I've been using it ever since. It's a daemon running on a local port for all web browsers to access. It now provides two features: Top Sites, inspired by Firefox's new tab, and a search bar with customizable engines, inspired by DDG's bangs (but it's a slash instead of a bang, to save you a shift press).

Check out the source code (0BSD): utab

utab is almost definitely not what you exactly wanted, given its intentionally limited config options and features, but given the power of free software anyone can build upon it themselves.

Also, it is 100% JavaScript-free.

Firefox - uBlock Origin

Firefox mobile - uBlock Origin

Chrome and Chromium - uBlock Origin

I think it would be great to sticky this and update it if uBlock Origin sells out like adblock plus etc did.

Hi all!
I am looking for a low-efforts zero-surveillance system to share bookmarks among several devices. For the moment being: a laptop and a mobile.
Suggestions about F-Droid apps are welcome, but not necessary!
