Both of those are tied to a group of one or more individual accounts. I've added your wikimedia.org address to the list of owners for the Chrome extension (which it manages through a google group called chrome-wikimedia-debug). However if you prefer your personal account (as I did), let me know and I'll add that instead.
For the Firefox one, let me know which account I should add there.
FYI, usage of Google Payments for my work account has to go through legal review, which is going to delay my ability to push this update to the Chrome store.
Maybe this time around @Krinkle you should push it for Chrome, I'll push it for Firefox and next time I'll do both? once ITS and Legal have figured out if/how we can pay Google $5...
If that works for you, I'll tag the new version and push it to Firefox.
