If someone had problems with 1.14.0 not working in Fx ESR, the developer pushed an update yesterday. 1.14.4 works and loads in ESR without any modifications. Just update your plugins. Thank you, Raymond!

@NeRkO20 (below): I can not confirm this. With 1.14.4, ebay.de works fine here. I click a lot of stuff through. Try resetting ublock settings and add filters one-by-one. Some rule on your side may cause this.
