why firebox is blocking all most site i try to access and disturbing ant virys

Hi, are you seeing a specific error message when you try to load sites? Could you copy/paste the error into a reply (or attach a screenshot - see: [[How do I create a screenshot of my problem?]]). Could you explain what you mean by "disturbing ant virys"? If you are seeing unwanted little popup messages in the lower right corner, those could be push notifications. Check whether any sites have permissions to push them using the steps in the following article: [[Web Push notifications in Firefox]].
