Not Win7 but I've seen good help here.
The spell checker on Firefox 23 (and all previous versions) /always/
reverts to Great Britain rather than US.
I thought I fixed this by disabling the GB language pack, but a few days
later it went back to British.
How can I get settings to stick?
Less importantly, is there any way to uninstall the GB language pack,
the only option given is "disable"
Some things to check here.

"spellchecker.dictionary pref on the about:config page"
If you go to the URL bar, and enter "about:config", the configuration
editor becomes available. In there, you can edit existing
entries, and assign new values. For items with binary
"True/False" values, just clicking the line will toggle
the state. While fields that take numbers, you type in a
new value.
The article above, also mentions the possibility of changes
not being saved. That's not a problem for about:config - as
it has no undo function, and the changes are immediate (as
far as them being stored in the profile). So while a change
made in a GUI preference, might not get saved properly,
about:config has the dangerous feature of storing things,
right or wrong (no undo, no cancel).
If you can figure out where the profile is, you can copy
that to a safe place (while exited from Firefox). And that
copy is then your insurance against accidents you might
have in about:config. That's how I handle the "no Undo" problem.
If I damage about:config, I just copy back the backup I made
minutes before hand.
If I still couldn't achieve the desired result, I'd go hunting
for the offending dictionary file, and delete it.
