I've been using UBlock for ages and was fully satisfied. Now, Firefox label this add-on obsolete and deinstall it regularly.

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?

I greatly value ability to selectively block web fonts with NoScript (AFAIK, uMatrix has no option to specifically block only webfonts on all sites by default). Unfortunately, after installing uBlock 1.14.4, it's fonts (image fonts in control popup) were blocked by NoScript… This didn't happen with older versions. I had to revert to 1.13.8 for now.

Aside from that, great job!

Firefox 55 uBlock Origin 1.14.4 Both on Windows and Linux
Works ok apart from having to update the same filters each time firefox is opened.

It's doing the job blocking ads but it is also blocking you from opening new tabs on sites.Can this be fixed somehow?

Been using ublock for a long time and love it!
It's disappearing from my add-on every time I close firefox and have to download it again to block ads! Please fix it!!

uBlock Origin v1.14.0

For some reason it started to disappear from my toolbar as well as disable itself.
