Diễn đàn hỗ trợ Firefox

When I start to log into one of my online accounts Firefox suggests several usernames. How do I tell Firefox to forget the extra/wrong ones?

TIA,

Paul

I have been trying for several days to sync a new computer to my account. I have followed all the suggestions including adding accounts@firefox.com to my email client online. Still never receive confirmation code email.

The settings page just shows a number, but no units as on my laptop's default font settings page. I think that they are pixels, but I'm not sure. I want to set my font sizes in points, so that the text will appear the same size on my laptop's screen as on my much larger external monitor.

I messed up. After downloading the latest version an erroer [failed to read config file came up each time I started. So I googled and the common answer was to reinstall. Idiot that I am I did notg back up bookmarks etc and so lost them all. I uised Recuva to retrieve deleted files and found 2 files places.sqlite-wal and places.sqlite.shm Is there any way to put these in the new Mozilla somewhere? I write now and all my research links were in there. Would be great to get them back somehow.
