Since the latest version uBlock doesn't work properly any more for me. When I search on Amazon und eBay the search triggers the link in the address bar but the site isn't reloaded with the correct content. I have to press the reload button. This also happens, when deactivating uBlock for a single side. When I deactive uBlock for Firefox, the sided work correctly.
I also deactived all other add-ons and just activated uBlock. The same error occured.
I even updated to Firefox 64 newest version, but still uBlock won't work in a correct manner. So I had to deactivate it completely.

That's sad, because it was a good add-on before the lastest update.
