How come my favicons are now grey boxes?

by on April 6, 2012

Q: I have been using IE8 & Firefox for years & everything was working normally all bookmarks had favicons in both browsers.
I upgraded Firefox to version 10.0.2 & all the favicons disappeared leaving a grey box but the book marks still worked. Some returned when I went to the website, but not all, & there are over 1000 of them. The strange thing is it affected both IE8 & Firefox. I tried “get places” for Firefox &
“FavIconizer-1.3” for IE8 but I can’t get all back. After getting wacked by a drive buy, corrupt link in a search (thank you Acronis), I uninstalled Firefox & I’ve gone to “Chrome” & when I imported the bookmarks from IE8 they all came in with default favicons. I realize that these favicons are using several formats,ico,png etc. but they were all there before the upgage.

Since this is affecting all the browsers & started with the Firefox upgrade could something have been change in the OS (xp-home sp3) that would affect all of them ?
