My pc runs on Windows 10. I've always had my bookmarks in a column on the left side of my screen. Yesterday I was unable to access my BT acount - which includes my emails via Firefox, wich is my default browser. BT Helpdesk suggested I try another browser - and sure enough I could acces the BT data using Google Chrome & Microsoft Edge. However my preference is to continue to use Firefox, and all other bookmarks worked witih Firefox, as did any other searches. The BT Helpdesk then talked me through resetting Firefox to Default - which worked in enabling me access my BT acount - and my emails - but my bookmarks are now lined up at the top of my Firefox screen and I've spent / wasted ages trying to get them back to the left side.
