I was using uBlock Origin for a very long time with great satisfaction.

Unfortunately, for the past few months, the plugin makes using Firefox a chore - a lot of web pages doesn't load on the first try, I'm greeted with the message:

"Hmm. We’re having trouble finding that site."

Once I disable the plugin, everything works fine again.

I'm afraid I will need to switch to a different adblocker and not recommend uBlock Origin anymore.
