Can browser extensions really protect your privacy?

Browser extensions are programmes that extend the functionality of web browsers like Firefox, Internet Explorer, Chrome and Opera.

Some do wonderful things (like add a moustache to all faces on the web, give you access to an array of web developer tools or simplify terms and conditions) and some are rather less wonderful.

Some of them are also very, very popular indeed with the most popular enjoying quite a few million users each, as this list of the most popular Firefox extensions illustrates.

One breed of extension that seems to be particularly popular are those offering online privacy protection or greater security when browsing.

Adblock Plus claims over 300 million downloads, Ghostery, over 40 million and Web of Trust, over 132 million. Eight of the twenty most popular Firefox addons (at the time of writing) can be categorised as applications that claim to offer some form of enhanced web browsing security or privacy protection.

5 ways to find images for your website

Finding good images online to use on your website or blog is fairly easy but finding images that are licensed for reuse can be hard.

It’s often difficult to know when it’s ok to reuse an image that has been published online and when it’s not. The internet may be a global network but each country has different copyright laws and there are no simple best practice rules applicable to everyone.

In this blog I’ll look at a best practice example of online image attribution, some of the problems that face anyone trying to work out if they can reuse an image online and five ways to find great images licensed for reuse, including:

  1. The Creative Commons search tool
  2. Museums, libraries and archives
  3. Getty Images
  4. Gratisography
  5. Taking your own photo!
