Of articles to add new functions to browsers to surf the internet we have already written several but they were always based on plugins and add-ons to install.
When it comes to enhancing a browser, what you can do with Firefox immediately comes to mind, of which we have the list of the best extensions and that of the best GreaseMonkey scripts.

But as said several times, if Firefox becomes a very powerful program thanks to the many plugins that you can put, every time you install something new, it becomes heavier and heavier, slowing down its loading. I Bookmarklet (Bookmark in the country means bookmark) instead they are absolutely not extensions to install but simply links that activate functions on the browser and that are launched from the favorites bar of any browser, sia Internet Explorer, che Opera, che Chrome e Firefox and any other software used to read and browse websites. Bookmarklets work also on Safari for iPhone and iPad and on every browser for Android. Technically, they are gods Javascript codes that are activated only if you click on them and that you don't have to install anything to make them work.

So in this article we see what they are the best bookmarklets to boost browsers.

Here I put some very useful ones to always keep at hand but if you know others, please let us know that we add them to the list.

Important Note, in this list I have put the links to the sites that distribute the bookmarklet buttons or the codes to add to the favorites.
To install these magic links that activate additional functions and make them appear on the browser's favorites bar, search the listed sites for the words "Bookmarklet", "Drag", "Grab" "Install". Then just click on them with the left mouse button, from where they are (not from here), and drag them to the favorites / bookmarks bar.
When the code is there, add a new favorite, then right click on it to change the URL by entering the javascript code as indicated.
