My linux mint OS periodically updates me to latest versions of FF. I notice system changes that I'm not sophisticated enough to correct myself. One such change is that new tabs don't always open when I click links, I have to open the new tabs manually. Recently I noticed that website links I used to visit are being redirected through a website called www.smartredirect.de/ ...that take me elsewhere (usually sex dating sites) than the desired webpage I wish to go. How do I disable this www.smartredirect/de action and recover ability to visit those websites I'd like to visit via their links? the offending website is: www.smartredirect.de/
