The plot thickens. According to the analytics data from this and a few other blogs, the usage of Microsoft Internet Explorer had another few % drop in September. Firefox is holding its ground while Chrome gained about 2-3%. It looks like a Battle of the Browser, the Battle for Your attention among the "giants"! But back to the case at hand:
Several Firefox users Matt, Jae, and Hanna among others have recently reported their Firefox browsers misbehaving badly. The symptom was a blinking (flashing) Close, Minimize or Restore Button in the window frame of Firefox. The blinking buttons flashed on and off upon pressing them. The functionality of the buttons was nil. They didn't work.
Today, a pop-up has appeared through my Firefox. I had never before received such a pop-up from Firefox! Quoting:
These Add-ons Have been blocked:Incredible! I checked and yes, I had .NET Framework Assistant 1.1 Extension installed in my Firefox. And yes, I had the Windows Presentation Foundation (WPF) Plugin installed in my Firefox. You can indeed find the .NET Framework Assistant and WPF in my original problem report to Firefox. I have yet to see if this will be a solid workaround for the problem described. Firefox is quiet about the details.
These Add-ons have a high risk of causing stability or security problems and have been blocked. Restart is required.
- Microsoft .NET Framework Assistant 1.1 [Blocked add-on]
- Windows Presentation Foundation 3.5.30729.1 [Blocked add-on]
Let me know in a comment if you had a similar problem with your Firefox and if this workaround (Workaround #4) of disabling the two Microsoft Add-ons or if any other 3 workarounds given here helped you or maybe NOT! Let me know either way! Just leave a comment below.
