For the last two days, I have been ubable to access settings (X,). When I click the settings cog in th toolbar, thr toolbar grays out. I have also tried to access settings using the Hamburger Menu, clicking on settings, with the same result. I have clicked on Firefox in the menu tab, same result. I have closed and restarted Firefox, with the same result. Additionally, I can only close Firefox by force quitting. I don't know if the two are connected. TIA. Keith
