Tip: Export your 'Bookmarks' to a HTML file for safe keeping.

Numerous times I have seen users that have browser issues or browser user profile issues and find it confusing or near impossible to retrieve their important ‘Bookmarks’.

Tip: Regularly export your ‘Bookmarks’ to a HTML file to a known location for safe keeping, this can be achieved with almost all browsers.
They can then easily be imported into a new user profile.
