It took ~ ten days to convince my family to move from IE to Firefox. I was about 11 years old at the time. People do not have strong attachments to their web browser. If you show them a viable alternative with tangible benefits, they might switch to it.
The other day I got a message from a website something like "this site is no longer supported on Internet Explorer, please try Chrome for best experience".
That was before bookmark and passwords sync, which now act as significant moats. You used to be able to import bookmarks from another browser, but you can't do that with passwords.
I don’t know the story about browser import today, but Chrome has a CSV export of passwords to presumably there is some mechanism to migrate passwords, no?
