Tipsy helps you make donation to web site whose content you read. You specify an overall donation amount. Tipsy tracks your use of web sites over time (that information stays with you; nobody else can access it) and periodically divides up your donation among those sites proportionally to the time you spend on them. You have complete control---you can change the amount you donate to each site or choose not to donate to particular sites. You can make the donations whenever you want.
More information is on the project web site, at http://tipsy.csail.mit.edu/
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
