According to the computer requirements, you have to set one browser as default. If you disable firefox from being default for your work and want to use IE instead, Follow this

1.Open Internet Explorer

2.Click on tool menu

3.Then click on internet option

4. In next box click on "Programs" tab

5. In this tab click on "Reset web Settings..."

6.Internet Explorer will be default

But if you wish to be running your work on Firefox with IE as default, you can right click on the file, and select open with Firefox.

But how do I disable that Firefox prompts you to set Firefox as the default browser. I have 1.000 virtual computers to manage at a large company Anyone?

You can use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.

Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.

pref("general.config.filename", "mozilla.cfg");

See:

• http://kb.mozillazine.org/Locking_preferences

These functions can be used in the mozilla.cfg file:

defaultPref();  // set new default value
pref();         // set pref, but allow changes in current session
lockPref();     // lock pref, disallow changes

You can use this line in mozilla.cfg:

// mozilla.cfg should start with a comment line
lockPref("browser.shell.checkDefaultBrowser", false);

Thanks, but the link was a litte confusing. -Wich value or variable do I have to change if 1.000 users dont want this check "Do you want to use Firefox as your deufalt browser..."

-Really appreciate your answer

Ps. Users get a new virtual desktop when they logging in, so nothing can be saved. They get this "Do you want to use Firefox as your deufalt browser..." every time they logging in. I have to change the registry in the central vDisk who is streaming this dekstops.

Sorry..didnt see this in your answer: "..lockPref("browser.shell.checkDefaultBrowser", false);.."

Should i write this on one row in the mozilla.cfg-file?

Yes, that should disable the default browser check in Firefox with this code in mozilla.cfg

Note that the mozilla.cfg file is a valid JavaScript file, so any errors (you need the correct quotes ") in this file (will) may trigger an exception that may cause the file to fail.
