You can make browsing with Firefox even better by adding extensions to it. With these extensions you can make surfing on the internet faster, safer, more fun, or more productive. Extensions can be of any type: comparing prices of products, customizing the look of your browser, correcting your grammar and spelling mistakes, or even getting access to the best coupons for online purchases. In the Firefox store you can find all these fantastic extensions.

Let’s start right away with our all-time favourite: TreeClicks. Unfortunately, most people don’t realize the consequences of online shopping. Just take a second to think about all the waste, CO2, and the pollution that comes with buying products. It should concern all of us. TreeClicks makes it possible for you to keep shopping online, while helping the environment at no cost. That may sound a little tricky, but here is how it works: TreeClicks earns a fee by bringing you in as a customer to its partnered shops. At the moment these are over 10.000 online shops. Most part of the revenue is then used to invest in tree planting projects in India. They are also looking for opportunities to plant trees in other parts of the world where deforestation takes place, such as Brazil. Trees cool the earth, so by planting more of them we will fight against global warming.

It can’t be easier: all you need to do is install the extension for free on your computer. Then, when you do your online shopping, TreeClicks automatically plants a tree for every purchase you do. The prices on the websites are kept the same.

If everyone would install TreeClicks, enormous amounts of forests could be planted. With this extension online shoppers can finally give something back to nature.
