add word to firefox's dictionary programatically

[xelawho]

when you click on the "add to dictionary" label in firefox's context menu, it calls this function:

oncommand="InlineSpellCheckerUI.addToDictionary();"/>

I'm trying to replicate that programmatically in a firefox extension. So it seems the first step is including this file in the xul:

chrome://global/content/inlineSpellCheckUI.js

which basically is just an include of this file:

resource://gre/modules/InlineSpellChecker.jsm

(these links both need to be opened in firefox, obviously)

so then in the jsm file we find the function:

// callback for adding the current misspelling to the user-defined dictionary
  addToDictionary: function()
  {
    // Prevent the undo stack from growing over the max depth
    if (this.mAddedWordStack.length == MAX_UNDO_STACK_DEPTH)
      this.mAddedWordStack.shift();

    this.mAddedWordStack.push(this.mMisspelling);
    this.mInlineSpellChecker.addWordToDictionary(this.mMisspelling);
  }

But what I want to do is add a word to the dictionary on a button click (or oncommand as xul would have it). So I was thinking this might work:

<button id="SpellcheckerAddButton" label="&addbutton.label;" oncommand="InlineSpellCheckerUI.mInlineSpellChecker.addWordToDictionary('fuzzlebuzz')"/>

I've included the chrome://global/content/inlineSpellCheckUI.js in the xul file where the button is, but I suspect that I'm misunderstanding the "this" from the original jsm file, because it doesn't work (and because it's xul, debugging is a nightmare).

Any suggestions?

I've no experience with plugins, but it seems to me that if you could do this in JavaScript, that would be a security issue.

Anyone else know more about this?

@ WolfShade

For sure it would be a security issue – for normal websites. Plugins are provided with extended APIs by the browser, so I think this could be possible. I don't know for sure, though, I too have never worked with browser plugins.

in case anybody is looking at this in the future, I haven't tried it yet, but it seems like this is what I was looking for:

@ WolfShade:
as Airblader says, you can't get at any of this stuff with just javascript, but with add-on extensions you can do all sorts of funky stuff (as long as the user agrees to install your extension)

for debugging you can run privileged/XUL code in firebug in about:config, but typically it's sealed-off.

oh, now you tell me

thanks for the tip. I'll keep it in mind for the next one
