PageSpeedOff v2.0.0
Provides a very simple quick toggle to allow/disallow the usage of PageSpeed.
Often the server-side PageSpeed caching can get in the way of web development & debugging efforts. This add-on provides a way to quickly avoid those headaches by requesting that the server not utilize PageSpeed.
The mode can be quickly toggled with the toolbar button. Current status will show in the tooltip (or on the overflow menu, if placed there).
