Firefox 58.0 64 bit. Just started doing this. I click on a link in a news story in an email and it shows for a fraction of a second that a new tab is opening, then it disappears and the original screen is still there. I can right click on the link, ask for it to be in a new tab and it will open. This happens even when I have the url as approved for popups. I receive the newspaper online through a link each day in an email. It operates just as I mentioned, very briefly shows a tab, then closes and the email window is there. I can go to my banking or insurance sites using my password program and all links work for me to navigate. Online, not through the email from the newspaper, my newspaper links work to navigate through the paper. Last night I closed Firefox and a few minutes later, when I opened it a message showed that Firefox was installing updates. I don't know if I have given enough info to make sense, but where is the issue here to correct?
