I run Windows 10 and had Firefox set up as my default browser. I could open and read emails w/o problems. Links inside them would open in my Firefox browser with no problem. I LOVED my Firefox! One day a couple weeks ago a box flashed for only a second or so and said something about changing a glitch in my browser. It didn’t ask me to click anything or even stay up long enough for me to read it. Now my Firefox browser is different and email links won’t open. I get an error box that says administration changes prohibit that operation. I have tried to find how I can reset it or fix it but to no avail. Has anyone else reported this? Do you have any solutions?
