Hi. I know of firebug, but this extension doesn't work in tor browser neither in iceweasel (debian firefox). So are there any other similiar extensions that allow to edit and execute edited websites?
Also does editing works, for example can I edit a form on a website so I bypass maxlength or set a custom value in radio buttons or other pre-defined forms?

Google Chrome allows it, but thats really the only other one I can think of.

You could try using Cheat Engine if you know how to use it :P

Isn't tor-browser just a ripped off version of Firefox?
Check the user-agent.

Yes it is. But after I try to install it it says it's incompatible.
