Many thanks, Asyn, that seems to have solved the problem 
However I am left feeling that I don’t really trust this browser, and I put in a support ticket to Avast 2 days ago and had not reply, I would like to export my bookmarks somewhere else as a backup, but the import options on Chrome or edge dont include this browser, I know it is a form of Chrome but it doesnt pick up on these book marks; I think I would have to somehow save them as a file and then upload them, any ideas how I could do that?
many thanks again
