With this extension, you can easily manage url parameters, edit/adding/deleting them with just one click, and you can also export or import the parameter list in CSV format.
How it works:
A small icon appears in each tab address bar, if you click on it you can see the list of all parameters for that url, that you can modify, export or import.
If the url has no parameter you can press "add new" and add as many parameters as you want.
Everything is just two click away...
If you are importing parameters from csv, be aware that if the first row contains parameter_name in the first column that line will be ignored, but if the above string appear in a different row, it will be treated as a normal parameter.
If you experience any bug or you want to suggest any new feature to be implemented in chrome parameters, you can click "report bug", and then enter your bug, or your suggestion (you can also add a label to classify it as a task or bug).
