Due to a drive failure I had to do a fresh Windows install. Since then my Firefox has not been loading tab favicons for the tabs from my previous session when I launch it. They do not display until I click on each individual tab. I have tried poking around in about:config and turned off several lazy loading functions but nothing has fixed it. '''browser.sessionstore.restore_tabs_lazily''' and '''browser.sessionstore.restore_on_demand''' are both '''false''' with no effect on this behavior. Any ideas for how to fix this?
