Remove English - United States language from Firefox

Question

How do I remove the English (United States) dictionary from Firefox? It's not an add-on so I'm guessing it's built into Firefox by default. Maybe that makes it unremovable?

I noticed whilst typing a Hotmail email in Firefox that the default language seems to be English/United States. As I am from the UK I thought I would add in the English/United Kingdom dictionary, which I have. This is now the default language and I don't need the US dictionary.

Firefox 3.6.2 on Windows 7 Home Premium 32 bit.

Answer 1

The dictionaries are stored in the dictionaries folder in the Firefox program folder (C:\Program Files\Mozilla Firefox\dictionaries) and you can remove the files from that folder.

The Mozilla Add-ons Dictionaries page is displayed. To add a dictionary to your Firefox installation, click the "Install Dictionary" link next to the dictionary you want to add. The Software Installation window appears. When it is displayed, click Install Now, which should open the Add-ons window, where you'll see the dictionary being installed.

To enable the dictionary, click the Restart Firefox button, in the Add-ons window. You can even see for more here.

Answer 2

To remove the en-US dictionaries so that they are no longer accidentally triggered, and to ensure that your chosen dictionary is used at all times, do the following:

1. Shut down Firefox.
2. Go to your install directory (“Mozilla Firefox”, usually under “C:\Program Files” in XP).
3. Look for the “dictionaries” folder.
4. In that folder, you will find the files:
   • en-US.aff
   • en-US.dic
5. Delete or remove these two files out of the folder.
6. Restart Firefox.
