Starting today, on Firefox 87.0 for Linux, any link that I had visited in the past is showing up as visited in the current session. I am in the process of updating thousands of listings on Ebay and the link color helps me keep track of where I am in the list each day, especially since I have had to start back from the beginning of the list 3 times. I do not want to clear my history as I keep going back to it to reference old pages. Is there a setting to clear the links visited color without clearing the history? Or is this a bug?
