8-8-24: SLow interface, takes forever to make the settings. doesn't reliably show on menu bar. needs better documentation showing for non-techies how to use the settings to avoid being profiled/blocked
4-25-24: You have to be a programmer to figure out which settings to use for which purposes. Not enuf documentation on this, you're riding BLIND.
5-2-23: mostly not using it because they need better guide on how to keep sites from breaking whilst still modifying ID parameters that the site uses to ID and track you and to BLOCK you.

update 12-11-21: many "not on whitelist errors"-cannot access website because they detect settings they do not expect, such as timezone changes or browser readout not congruent with you usual login-especially with FBook. Still slow to load.Program needs further documentation to teach users which settings will break sites or not. Basically an ok add on that could use some improvements.
UPDATE 9-29-21: CANNOT HANDLE POPUP ALERTS FROM OTHER PROGRAMS SUCH AS VPNS, ETC. YOU HAVE TO CLOSE ALL OTHER POPUPS TO LOAD IT. EXTREMENLY SLOW TO LOAD UNDER LATEST FFOX. FACEBOOK BLOCKS YOUR CONNECTION IF YOUR TIME ZONE DOES NOT CORRESPOND TO YOUR ACTUAL IP REGARDLESS OF WHAT CHAMELEON TELLS THEM.
ALSO BLOCKS IF YOU USE THE WRONG BROWSER SELECTED BY CHAMELEON. APPARENTLY CHAMELEON IS MORE LIKE "WE ARE HACKERS" TO FIREFOX THAN ANY SO CALLED CHAMELEON DISGUISE. FB TOO SMART FOR CHAMELEON.
UPDATE:7-14-21: Basically a good add-on. Good documentation and user instructions lacking in similar addons. Biggest complaint is slow to load gui and slow to respond to user input. Documentation could still be improved for non-techies as it's very hard to determine which settings will cloak you without breaking a site and which settings actually work to disguise your identity.
UPDate: 6-10-20: Big improvement especially in the documentation. A good add-on. A little slow to load and change the settings. Not really sure this program will mask you as unique, but it does work without being buggy. Overall good program and cudoos for the documentation help pages.
UPDATE: 5-13-20 DOES NOT WORK with tor firefox latest version. Cannot set settings. worthless and disabled.
very granular control over all your browser settings, but breaks sites often. you have to experiment to get it right. need to have better help manual for this as you have to be an expert to figure out the impact of all the settings. update 5-3-2020. They broke it with the latest update, no longer works properly cannot set settings.
