Is there a way to add an entire list of words at one time to persdict.dat?

I added an entire list of words (several hundreds) to persdict.dat each word on a separate line then saved the file and all looked OK. However, none of those words are recognized as OK by Firefox's spell check. Clearly, that's not the way to do it. It seems one must use the "Add to dictionary" thingie FOR EACH WORD, WORD BY WORD in order for it to be recognized by Firefox's spell check. There has to be a better way.

I solved the problem a couple days ago. The mistake I made was that I neglected to shut Firefox down before making the changes to persdict.dat. Once I did that, everything worked as I expected it to work after bringing Firefox up again. I guess that's the equivalent of what you suggested. Thanks for your response.

After you made the change to the file, did you restart Firefox?
