I don't think this is an error message, a glitch, or what - Firefox prevented this page from automatically redirection to another page. I get this several times a day now, on perfectly safe sites I've used forever without problem. Sites like my bank, investment companies and adobe login. Less and less is it opening the page when I click Allow. I get a white page with the address still filled out and the Firefox prevented this page blah, blah, blah still there. I've restarted, cleared cookies, and cache, shut off the few add-ons I have, but it didn't help nor did changing config:about blocking true/false. I'm wasting a lot of time trying to find out what is going on. Could someone just tell me what button to push to stop this endless cycle of annoyance. Pretty please. Thanks to the Wizard that has the answer. Windows 10 Latest Firefox
