Lord Gaga. I'm using Firefox, also. Like Charlie, I'm not seeing any change in the Firefox Format.
Consider referencing the rectangle in the upper right corner of your Firefox web page. Click on the rectangle and go down to the question mark next to the word 'Help' next to the bottom of the list . . .
Click on the Help listing . . .
On the page that opens, click on 'Firefox Help' . . .
On the page that opens, go down to the exclamation mark on the 3rd row down that reads 'Fix Slowness, Crashing, & Error Messages, and Other Problems'. Click on it.
On the next page that opens, go down to the 9th title that reads, 'Refresh Firefox'. Click that title and you're on the path to refresh Firefox.
Refreshing Firefox should get you squared away.
Hope this helps!
