EarthTab is a free Chrome add-on developed by Dave Lunny that allows you to turn your new tabs into stunning windows showcasing Earth's natural beauty. By pulling images from Reddit's SFW nature porn, EarthTab brings the breathtaking landscapes and scenic views submitted by the Reddit community right to your browser.

With EarthTab, you have the option to choose which specific nature subreddits you want the images to be pulled from. This customization allows you to curate your own collection of nature images for your new tabs. Additionally, you can also set the frequency at which new images are searched for, ensuring that you always have fresh and captivating backgrounds.

Please note that EarthTab is currently in Beta, which means that there may still be a few lingering issues and requested features that are yet to be added. However, this published version should be relatively bug-free and provide a delightful experience.

EarthTab is an open-source project and the source code is available on GitHub. It is licensed under the MIT license, and it was built by Dave Lunny in the year 2015.
