For a few months, and I've seen this happen randomly over the last 5-10 years - pressing enter doesn't work, and sometimes dragging a new link into the empty tab space next to the tabs creates a new tab with the URL in the URL box, but not 'opened' Does firefox have some issue with loading a web page? I use ublock origin on default settings, and violent-monkey and stylish for scripting.. but would that disable searching google from a new tab?
