If you are just removing the mirror from the glass, it is usally held on to a windshield button by a small set screw. If not, it is probably held to the button by wedge mounting to the button. The button itself cannot be removed from the glass without breaking the glass. If the button comes unattached, you can reglue the button with a special remount kit sold at auto stores.
Remove the mirror and use a heat gun to remove the button. Caution: There is always the possibility that the windshield will crack.
Which mirror? Just guessing you mean the door mounted mirror. Remove the inner door panel. There will be two nuts holding the mirror on. Remove them and pull the mirror off. If you mean the windshield mounted mirror, there is a small Allen or torx screw holding it on. Loosen it, slide the mirror up and remove.
Look at the mirror, and find the retainer screw. Loosen the screw and slide the mirror up, toward the roof of the car.

I've done a lot of research and trials with failure on a 98 XK8 conv. According to my service manager if you try to remove the windshield bracket it usually breaks the windshield, which is why the dealership won't just replace the mirror anymore. In my case, my mirror still works but hangs or wobbles now that it's glued with windshield sealant to the bracket when the connector broke. My plan is to replace the badly sand pitted windshield through insurance and at the same time purchase a new mirror +/- $500 - 15% coupon ($75) = $425 and have the glass company install the whole thing which they do as part of the windshield installation.

Insert a small pick under that little bit of metal and pull the metal away from the windshield then push the mirror bracket straight up and off the windshield. No, that didn't work. The little bit of metal doesn't move. However, brute force with needle nose pliers does.
