How do I change the language of Firefox 4?

Solution 1:

You need to download the English version. The version you have will be the Hebrew one.

Solution 2:

Download the English version. I don't think it's possible to change the language of an already installed browser.

Solution 3:

You can install a plugin with the right language. All languages for Windows are found here. Browse around for other platforms.

Also you can find installers there for every language separately.

Solution 4:

Go to the site http://kb.mozillazine.org/Change_Default_Mozilla_Language, download the proper language pack and install it as add-on. Success. jrm
