I therefore started to develop my first greasemonkey script to have Firefox do that automatically.

It is not the first one around, I particularly like that one, but for the exercise, I wanted to develop mine using Yahoo! Finance exchange rates.

2. Install GreaseMonkey

3Configuration

When you first load a page after the installation, the script will prompt you what currency you want to convert to. You can enter one of these.

If you wish to change it later, you can by going to the menu item:

tools -> user script commands -> Change currency conversion

4Styling

You can personalise easily the style of the conversion value by adding in you file chrome/userContent.css (in your firefox profile directory) a css declaration with selector a.GM_CurrencyConvertion.

For example:

5Updates

Since v0.2, the script supports the auto-update script for greasemonkey. If you have installed it, then the update will be made automatically when a new version is availlable.

6Todo

1. Localisation
2. Manage symbols (like $) associated with multiple currencies
3. understand "european" notation: 6’000,10 CHF

8Changelog

v0.4

• I added support for a lot more unicode symbols. However, many of the symbols are linked to multiple currencies [1]. I randomly selected one for each symbol, if you want to change that, go open the .js file and comment/uncomment the line that interest you in the currency list.

v0.3

• now interprets 6k$ as 6000$
• now works with coma in the number: 6,000$ and 6’000$
• corrected the insertion class name to GM_CurrencyConvertion

v0.2

• Corrected the class of the insertion
• Corrected the waiting for exchange rate when there was only symbols on the page
• cleaner code.
• suport for the auto-update greasemonkey script
