A workaround is to use the Dictionary Switcher extension.

I don't see it. Please reopen if you still can reproduce it.

Reopening bug since it is still an issue. I tested with:

* RHEL 6.3
* kernel-2.6.32-279.2.1.el6.x86_64
* firefox-10.0.6-1.el6_3.x86_64

The language was set to "English / Zimbabwe". We are proposing that the language for Firefox be determined by the user's region.

Also, posting the output of "locale" command as requested:

# locale
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=

I'm also seeing problems with firefox and the dictionary in fedora 17.  This bug post for Ubuntu 

https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/940341

suggests that something is going wrong when firefox gets updated, and that happens a lot with the new rapid release schedule that mozilla has gone to.

I have zillions of dictionaries on my system (mostly because there are or were packages like open office that drag them all in) and when this bug hits me, it's not just a switch from one dialect of English to another.  Instead, it sometimes seems to reset itself to the first dictionary in alphabetical order, which is typically some form of Arabic.  Although I've also seen Zimbabwe...

This problem still exists on Fedora 18 as well which means the issue will carry over into RHEL 7. Can we please finally fix this annoyance? My default language was set to English / Hong Kong this time on a fresh F18 install.

If you remove the lnagpacks directory (on my install it is located at /usr/lib64/firefox/langpacks) and then restart Firefox then you will be able to set the dictionary language to the setting of your choice. I have no idea why this works, but it does. Odd bug, but here is a simple fix for you. Assuming of course that you speak American English.

Just for the record, this seemed to have been fixed on Fedora 19, but is back on Fedora 20.

Related Fedora bug #1007653

Not to add fuel to the fire, but I am experiencing the same problem as well. I have en_US as the locale, Hebrew as an optional language on the keyboard. However, the default dictionary is French!
I don't understand why, but that is what it is. When I change the dictionary to English, all is good. However, it is not static and needs to be set on a per/instance per/application basis. Each time I type in a new application I need to set the dictionary. A total nuisance!

My locale:
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"

LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
