Bookmarklets vs Mozilla Extensions
You have seen how bookmarklets can greatly expand your option for
translation and character conversion. Bookmarklets can do many other
things, for example, search and highlight text and navigate pages.
Many of these functions can also be done with extensions, but
bookmarklets and extensions are different in many ways, the most
obvious being that that you don't need to install a
bookmarklet. Here are some more differences:
- A bookmarklet has the normal script permission every Web
site has, so it can do everything that a site can do. This also
mean it cannot do other stuff, such as changing your browser
preferences. In contrast, an extension can control virtually any
aspect of your browser. In some ways, bookmarklets can be
considered to be more limited but also secure than extensions.
- A bookmarklet is controlled by your script preferences. If you
disable script for Web sites, you also disable bookmarklets.
Extensions are note affected by this preference.
- A bookmarklet is easier to code. A bookmarklet is basically a
bookmark with script code in it, and it can be used on other browsers
such as Internet Explorer. If you are looking for a simple shortcut,
you are more likely to find a bookmarklet than an extension. As an
added bonus, you can also share bookmarklets that you made.
In general, bookmarklets are simple tools that you can add and delete
at will. They are very useful for page navigation and other Web page
related functions, but they cannot replace extensions in more
