Disabling firefox spell-checking:
Mozilla allows you to turn off the spell check, which is a handy feature for us brainiacs. Just go to the Tools –> Options –> Advanced –> General and deselect the box that says “Check my spelling as I type“. The spell check will no longer function!
If you want to add bulk of custom words you can goto dictionaries folder which resides in Firefox installation folder and open the dictionary file of your language in wordpad and append the set of words to the bottom of the file.
Alternatively you can add the custom words to the custom dictionary file.The name of the custom dictionary is “persdict.dat” (short for “personal dictionary”), and is located in the following location (depending on operating system):
C:\Documents and Settings\[username]\ApplicationData\Mozilla\Firefox\Profiles\[unique-alphanumeric-string].default\persdict.dat
Mac OS X
Of course, the
[username] (for Windows) and
[unique-alphanumeric-string] will vary depending on your unique configuration. Once you have located the target file, “persdict.dat“, open it with a text editor and edit according to your needs. The file itself is simply a list of words that you have chosen to add to the dictionary by right-clicking in Firefox and selecting “Add to dictionary“.
Note that “persdict.dat” will not be found in the above mentioned locations, unless you added custom words to the the dictionary. You can add a custom word marked as a typo to the dictionary by simply right-clicking and choosing – you guessed it – “Add to Dictionary” from the context menu.
