Thank you! I've added all the options to my Firefox browser that you suggested in your last post. Very much appreciate your terrific help and guidance.

I entered the options shown in your 'Settings' for Firefox and I can now perform searches on my address bar. Great! Many thanks for your help.

Thank you for your reply and suggestion. However, a domain is not being blocked. Rather any attempt on my part to do a search on the address bar. For example, if I enter "best restaurants near me", I get the message "Website blocked due to pup". It doesn't matter what I search; I always the the same website blocked message.

Malwarebytes is blocking searches Firefox address bar. If I enter a search in the address bar, I receive the following message: "Website blocked due to pup. Website blocked: mysearchengine.co.Malwarebytes Browser Guard blocked this website because it may contain pup activity." I've used Mawarebytes for a long time with Firefox and never had this problem. I'm using Malywarebytes browser guard with Malywarebytes Premium Version 4.5.0.
