I've had Facebook bookmarked on my Firefox browser for years, and have never had a problem logging onto Facebook by simply clicking on the saved bookmark...no need to enter my Facebook password. Over the last few weeks however, the first time I click on the bookmark to log onto Facebook each morning, I'm prompted to enter my Facebook password to log on, use the code generator, etc. The messaging states that my Firefox browser isn't recognized by Facebook, ever after I save the browser again, each morning, while completing the log in to Facebook. After I have successfully logged on each morning, I can access Facebook for the rest of the day by simply clicking on the saved bookmark. But I have to repeat this process each morning. I used the Microsoft Edge browser to log onto Facebook yesterday, went through the whole log in process, code generator, saved the browser, etc., and this morning was able to log onto Facebook via Microsoft Edge simply by clicking on the saved bookmark....no need to re-enter my Facebook password. Is there a way I can fix this problem in Firefox settings, so my Firefox browser will again be recognized by Facebook when I click on the saved bookmark? Thank you.
