I have an on going problem with Firefox. Sometimes when I go to save a new bookmark, as soon as I start typing, the new bookmark vanish. I then have to go into bookmarks menu, find the new bookmark which may be titled "No Title" or just a "small square" and re-title it. As I start typing the first letter of the new Title. The typed letter appears on my screen and quickly vanishes. I have to retype the first letter again and then it works correctly. I have tried many things to fix this. Emptying Firefox cache, Refreshing Firefox many times, Running Windows 11 clean up corrupt files, making sure there is no spy wear of bad files on the computer. I have reinstalled Firefox many times but the problem quickly returns. ( I have wondered if something on my computer is corrupting Firefox, but I cant think, or find out, what it my be.) I have run the program Restoro many times which claims to correct problems but it doesn't fix this one. Had a technician look at it, but his advise was to contact Mozilla. The problem does not always happen and is worse when I first turn the computer on. It plays up on the first new Bookmark I make and then sometimes works correctly. My Bookmark folder is very large and contains much information in a Book, Chapter, Paragraph, Sentence structure. Has anyone experience this problem and how did they fix it? I use a dedicated Solid-state drive for my bookmarks and according to Samsung Magician it is working correctly.
