I am experiencing a very annoying problem with FireFox 11.0 on Windows XP SP3, and unfortunately it is making it very difficult to use one of my favorite sites!!!
This problem appeared several weeks ago. Anytime I navigate to a Stack Exchange site (i.e. this site, SuperUser, but also StackOverflow, ServerFault, etc.) I am presented with 5 - 10 of the following pop-ups - on every page:
A few things to note:
This pop-up does not prevent me from viewing the page. It is just very annoying. I can enter in my username / password to no effect, but I also can click cancel repeatedly. After about 10 tries, I finally can read the page (but have to start over on the next page I view).
This problem doesn't occur in IE.
This problem does not occur with any other web sites, just StackExchange sites. Why?
When I do enter my AD user / password, FireFox pops up the "do you want to remember this username / password?" popup (see here), but is immediately dismissed by the "moz-proxy" pop-up.
I am not using (nor do I want to use) any sort of proxy add-on like FoxyProxy.
Please help as I want to be able to use my favorite developer site whilst at work again :(
