Hi kiedis, could you check the preferences here: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk. (2) In the search box above the list, type or paste '''inback''' and pause while the list is filtered You should see at least 4 preferences, two of which would be most relevant to your scenario. To switch between true and false, double-click. * '''browser.tabs.loadInBackground''' (default is '''true''') -- this should cover your scenario if it's a regular link that would have opened in the same <s>page</s> <i>tab</i> anyway. * '''browser.tabs.load<u>Diverted</u>InBackground''' (default is '''false''') -- this should cover links coded to launch a new window that Firefox diverts to a new tab instead. Can you find a combination that works for you?

Thank you very much, Jefferson
