Hello, It sounds like you are using the premium version of Malware Bytes which has a web protection feature blocking websites. The site 'yuq.me' seems to be an image hosting site (based on this post - http://kickassunblock.net/community/show/how-fix-yuq-me-links-easy-editing/ ). This means that if you are browsing sites such as forums where users are posting (links to) images, Firefox will be trying to connect to this site. You can try asking for more information on the MBAM forums: * https://forums.malwarebytes.org/
