Visible Errors is a browser extension for Chrome, which shows you every JavaScript error on your pages visually, using a notification system similar to Growl. This can be used for developing web apps, when you may not always have the console open. The way JavaScript was designed, a single error doesn't necessarily stop execution of your web app. DOM events still execute, timers still fire, etc. Sometimes an error may be thrown but you may not even notice it. Visible Errors puts a stop to that. As a programmer, I want to see every error thrown by my apps, whether I have the console open or not.
Visible Errors shows notifications right in the page on which the errors occurred, in the top-right corner of the window. They have a "fixed" position, so they aren't affected by scrolling. If you have IFRAMEs in your app, they'll appear inside the frame, when appropriate.
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!
