Hi avast friends,
Do you use a Mozilla type browser like Deerpark, IceWeasel, Firefox, Flock, and you are a webdeveloper also, here are some nice extensions:

Are you trying to force that old extension/add-on that you cannot live without, you can force it on Flock anyway, but when you run Firefox with the nightly tester toosl, that wiil enforce it when you tag that option. To have complete control over your extensions and themes install the MrTech llocal install extension. Link evaluator, header monitor and cookie editor.
Enjoy,
