Pinned Tab Thumbnails Won't Display Until I Refresh The Page

[Infernoflower1]

Hello, since I updated Firefox, every time I start it, my pinned tabs don't display their icons until I refresh their pages. I've tried scanning for malware and adware , and installing FavIcon Reloader and that hasn't fixed the problem. How can I fix it? Here's a screencap of what the icons look like before I refresh the pages: Please ignore the content of the thread shown in the screencap as it is not the same as my problem. The problem is the two tabs in the top left corner.

Sorry, ignore this. It looks like the problem's been fixed.
