MathEval is a Firefox extension that acts as a lightweight calculator in your statusbar. Demo video available on Youtube (http://www.youtube.com/watch?v=9mC6S78YQGs)
Here are some key features of "MathEval":
· Expanding box in the statusbar
· Automatic clearing
· Displaying your mistakes
· Works with all-glass mod (https://addons.mozilla.org/en-US/firefox/addon/12181/)
Requirements:
· Mozilla Firefox
Limitations:
· Uses the JS Eval function to evaluate a the user input, which is unsafe. Actually, you can crash your browser or do something even worse (if you try hard, and research), because the code is running in chrome level. I should change to evalInSandbox, or something more sophisticated.
· No locale support (because it only contains a single string, "error")
· Not works well with All-glass mod (the text is glass in the box, windows uses black fields as aero)
