oigroig: i would want a script that show me the prices in euro but i don't know how to use userscript on opera
Any help?
The script doesn't work correctly under Opera anyway, and I'll need some time to figure out how to make it function (I pretty much abandoned it since there was no feedback coming in, and I don't actually use it myself).
But for the future, to install user scripts under Opera:
1. Create a folder, anywhere, that you'd like to store the scripts in.
2. In Opera, go to Preferences->Advanced->Content->Javascript Options...
3. Choose the folder you just created, with the appropriate setting.
4. Save/move/copy, the scripts to said folder.
1-3, of course, only needs to be done the first time.
In the meantime, Pinky69 has a quite good solution. Google is a very good currency converter, copy-and-paste "5.99 USD in EUR" or "9.99 USD in EUR" (without the quotation marks) to get the conversion.
