Usually very good. Works like a charm.

Then on the other hand. Strange hickups after automatic updates.
Right now version 1.14.8 stopped working with Firefox 56.0b8.
Deinstalling, installing. Nothing helps. The icon disapears from shortcuts bar and no settings are available. No adblocking at all.
Had to go back to version 1.13.8 (https://addons.mozilla.org/firefox/downloads/file/685614/ublock_origin-1.13.8-an+fx+sm+tb.xpi)

Any idea what might be the problem? How to solve this?
