Lately most times when Firefox updates it wipes my tabs and I have to rebuild them because backing up the tabs won't work so I got in the habit of going to bookmarks and reloading them from there. Today it not only won't automatically open my tabs but won't let me even load most hand selected tabs. I have been using Mozilla, Netscape Navigator since the early days with no other problems except this. I have been using Avast Premium Security on windows 10 and it reports no problems. I will have to check one of my Linux machines because Firefox won't open the tab for Hotmail. Any help will be appreciated.
