Diễn đàn hỗ trợ Firefox

This has happened a few times before after a Firefox update, but the most recent occurrence was after the update to version 117.0.1. My mouse wheel will not scroll in the bookmarks drop down menu, I have to use the up and down arrows in the drop down menu which is very slow. When the scroll wheel did work in the past, I could be scrolling and then move the cursor to the up or down arrows and scroll even faster still using the scroll wheel and get to the folder I want a lot quicker. The scroll wheel works normally while scrolling through webpages, the only place it doesn't scroll is the bookmarks drop down menu. I'm running Firefox version 117.0.1 (64 bit) on a Windows 10 notebook PC. Any help would be greatly appreciated, thank you.

This morning, I brought up Firefox and found my bookmarks (including the toolbar) had vanished. I tried restoring my profile folder, but that didn't help. I also tried restoring the bookmarks from Firefox's own backups, but I got some "Unable to process backup file." messages. What do I do now?

I have just updated to Firefox115.2.1 ESR. On the recommendation of Mozilla! The small icon next to my bookmarks are missing and the bookmark doesn't work. Only a few of the bookmarks have an icon. I have a large number of bookmarks, so I do not want to create them again. It would take me hours to do. I have tried to import bookmarks backup but nothing seems to happen.

I hope someone can give me a quick simple answer. Thanks Brian
