Cannot open .jnlp file when asked to open with firefox web browser in ubuntu 11.10 using firefox 6

After upgrading to ubuntu 11.10 the firefox 6 browser cannot download and open .jnlp file from the interactivebrokers website. Usually I go to the IB website and download tws.jnlp file which is opened in the firefox web browser. But now when I click on the Open with Firefox Browser button, the firefox browser opens a new tab and display the same open window again.

Re: Cannot open .jnlp file when asked to open with firefox web browser in ubuntu 11.10 using firefox 6

Seems that after upgrading to 11.10, jnlp files open with firefox instead of javaws (Java Web Start). If you right click the file on the download folder and choose "open with" you can manually select java web start. Ubuntu bug...

You can right click any .jnlp file and select "properties", go to "Open With" tab, mark Sun Java 6 Web Start and click "Set as Default". Should fix it. I don't know what would happen if you have the default ubuntu java instead of Sun's. Maybe this wouldn't be necessary.
