You may visit the same website several times a day, or use a search engine several times. So, how can you quickly access these frequently visited sites? Obviously, typing that long list of links by hand is not the best way to do it. In fact, you can use Firefox's keyword bookmarking feature to instantly navigate to your favorite sites.
For example, if you want to look something up on Wikipedia, you can use Ctrl-L+w to look it up. In addition, you can use the Foxmarks extension to sync your favorite Firefox sites or keywords at work and at home.
Of course, Firefox also has a large number of add-ons to meet the needs of different users, which is not yet available in any other browser.
