After reading your comment, I went to the bookmark manager in Firefox. Looks like Firefox supports tagging bookmarks. But finding them again using tags seems a bit cumbersome. You have to go the the menu to search bookmarks and then enter the tag.

ctrl + L to go to the address bar then type * <space> to search in your bookmarks.

Replace * with ^ to search in your history or % to search in your open tabs. You can also try @google or @wikipedia to search on those websites.

I love those shortcuts! This is the kind of features that make Firefox far superior to Chrome in my opinion.
