Are you saying that all the menus (tap the Alt key to show menus) and toolbars are in Spanish? In that case, you might need to install and English version over the Spanish version. First, if you have accumulated any Firefox bookmarks, I recommend backing up your Firefox settings. Just in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.) To get an English installer (or your other language of choice), choose from the full list here: [http://www.mozilla.org/en-US/firefox/all Firefox web browser | International versions: Get Firefox in your language]. After closing Firefox, you should be able to install over Firefox 6. Any luck? ---- Note: if you mean in Google, then look for a link toward the bottom to use Google.com in English.
