Not sure why FF is the only browser that doesnt update the favicons properly. I never have an issue with Chrome or Edge and they display properly. Yet FF always has wrong icons. For example. If viewing New York Knicks website the tab page icon is correct for the team's logo. Yet the bookmark is always the generic NBA logo. Chrome does not do this and works as it should. The bookmark icon is correct, but not FF. FF needs to be able to update its icons properly or be able to read the sites address to update the icon better. This has been an issue for years. No matter what troubleshooting steps were taken or removing sqlite files. FF just fails to update the icons properly. Even with a new install, refresh with new profile. Wont do it.
