I'd probably doing myself a favour if I accidentally deleted mine. There's so much junk there...

In any case, I don't use them for the sites I use most frequently. I've the most common as pinned tabs on chrome. I get to the next most frequently used ones simply by typing a couple of letters in the address bar and letting the browser complete the url (eg. typing mu is enough to get firefox to bring up http://www.mudcat.org here).
