not sure yet, but some presets definitely not OK Rated 3 out of 5 stars

I'll give it a tentative semi-positive assessment. First, to echo the warning posted months ago by RevSyd: the "strongest" preset configuration that exhibited no problems was the one called Courteous. Beyond that I instantaneously got squawks from Gmail (connectivity problems, Google whined) and - ironically - the Firefox Add-Ons website (it would not load at all). Unacceptable, to say the least.

On the other hand, set to its Courteous configuration, I *think* it causes faster page loads and, so far at least, no complaints. Hard to say, because load times for a particular page will vary anyway.

To be fair and complete: I have seen similar counterproductive things occur in the past as well, with other add-ons of similar purpose installed in the Firefox version of the time.

This review is for a previous version of the add-on (3.9.1Lite.1-signed.1-signed).
