Bug Magnet Chrome/Firefox Extension
MIT License
Exploratory testing assistant for Chrome and Firefox. Adds common problematic values and edge cases to the context menu (right-click) for editable elements, so you can keep them handy and access them easily during exploratory testing sessions.
The easiest way to install the extension is from the Chrome Web store or Mozilla Add-ons.
After installation, just right-click on any editable item on the page and you'll see a Bug Magnet submenu. Click an item there, and it will be inserted into the editable field.
