Rated 4 out of 5 stars
I'm using this with FF 7.0.1. Overall it is simple and works. It even puts the cursor where I want it on loading. However I too have noticed the glitch where it overrides a specified URL that should be opened. In particular, I have Firefox set to restore my previous session on startup. Any tab that gets displayed while they are loading at this time is redirected to the NewTabURL default (and it's impossible for that not to affect at least one). Moreover, while the affected tabs do still have their history, if I use the Back button to go back to what it should have been, that somehow forces all the other tabs to reload *again*. I have never seen that happen in any other situation; something odd about the way the add-on forces the redirect, maybe? This would be a showstopper if I restarted every day.
