There is a website that I go to that has suggested UserIDs in the dropdown box. I have tried to clear those through the privacy/clear settings in Firefox. Nothing clears them. I have tried uninstalling and reinstalling, yet the data is still there. I have cleared, deleted with every setting I could find, to no avail. I am using 138.0.1 (64-bit). Any suggestions are welcome. Thank you. **** It finally cleared after clearing data about 5 times. Moderator can please delete this question. Thanks.
