Question 1

What is a bookmarklet?

Accepted Answer

A bookmarklet is a small JavaScript program stored as a bookmark in your web browser. When clicked, it executes JavaScript code on the current webpage, allowing you to modify content, extract data, or enhance functionality without installing browser extensions.

Question 2

Are bookmarklets safe to use?

Accepted Answer

Bookmarklets are generally safe when obtained from trusted sources. However, since they execute JavaScript code, you should only use bookmarklets from reputable developers or those you've created yourself. Always review the code before adding a bookmarklet to your browser.

Question 3

How do I install a bookmarklet?

Accepted Answer

To install a bookmarklet, simply drag the bookmarklet link to your browser's bookmarks bar. Alternatively, you can right-click your bookmarks bar, select "Add bookmark," and paste the JavaScript code as the URL. The bookmarklet will then appear as a clickable button in your bookmarks.

Question 4

Do bookmarklets work on mobile browsers?

Accepted Answer

Bookmarklet support varies on mobile browsers. Some mobile browsers like Safari on iOS support bookmarklets, but installation requires manual URL editing. Chrome and Firefox on Android have limited support. For best results, use bookmarklets on desktop browsers.

Question 5

What's the difference between bookmarklets and browser extensions?

Accepted Answer

Bookmarklets are lightweight, single-purpose JavaScript snippets that run when clicked, require no installation process, and work across different browsers. Browser extensions are more powerful, can run automatically, have access to more browser APIs, but require installation and are browser-specific.
