The UI/options and documentation might be a little bit unintuitive and sparse, imho. However, with experimentation to figure out what each option really does, this really is a highly effective tool that runs smoother than the 2 or 3 other addons it replaces.

I love your plugin but Your latest Version 0.20.3.1 has a few bugs,
1. it stops sites to work properly, I have to disable it to make them work and then I re enable your plugin, It doesn't let Dailymotion video to play when its embeded in site.

2. It usually do not pick up timezone whereas previous version did.
and this new version doesn't let me delete the email in tutanota mail earlier I used to (again I disable plugin to delet mail and then reenable it)
and there are few other things... so on...

3. You imposed a few features rather giving choice like Cookie (Policy). There is no way to disable it, once has to select Allow visit bare minimum whereas the fact is I already use Firefox privacy feature to handle cookie functionality.

May I know why you will fix them?
Regards

latest version not functional. cannot set timezone, and many other parameters. go back to earlier version which worked. Because you screwed up your upgrade. we are not here to debug your bad programs.

Great addon, thanks sereneblue. Too bad last updates (v0.20.1 now) took over Firefox cookies management and you can't manage cookies permissions on a per-site basis anymore. Or can you?
I used to allow cookies only from a handful of websites.

It used to work fine until This Addon was updated.
It breaks Youtube, video list on channel page does not load properly.
Can you please fix this issue with youtube ? I do not use any settings except for spoof IP timezone.
I think i'll revert back to old version.

Works fine, almost all sites load perfectly with the correct settings granted you don't go in like a noob and go nuts with all settings and don't read the documentation.

One issue though is YouTube, extension updated to 0.20.0.7 today and YouTube ended up loading without polymer, basically it literally loads as if it was YouTube during 2012 or something with no dark mode and less features.

Edit: Thanks for doing that! That was pretty fast, I can finally use it again.

Hello, please how can i manage the extension and choose what i want to spoof and what i don't want to choose.

thanks

7-5-25: Really not sure what this accomplishes as website probably just identify the changes you have made and get the real settings despite them? No really good instructions to help you to actually sppof your browser and other settings. false security and blocked by many sites. Maybe better than nothing not sure.
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.

Nice work, i love it., Please add more screen sizes, like please add 30 to 40 in this list, Please update this asap....really nice add-on...only screen sizes issue....

Good extension. Could you add more screen sizes to next update, Also please add more windows and mac os browser versions.

https://whoer.net/ still shows my *real* userstring (by JavaScript) instead of the spoofed one.

Can i fix that by toggling one of the configuration settings of Chameleon?

Good convey of development from RAS

Works like charm. Please add option to disable pdf.js

If I choose Enable resist fingerprinting option, user agent tests show me Windows 10 and Firefox 68. And nothing I can change (I tried manual user agent selection, real profile, whitelisting site etc. Nothing changes). My real OS is Windows 7 x64 and Firefox 72.

Along with the Advanced Preferences (about:config) this is better than a VPN !
Excellent work !
Thank you very much.

Bravo devs for being responsive after making this useful but not java disabling levels of supposed obscurity. Perfecto 7*

This seems to be the complete package for browser profile spoofing. Does a lot more than just change your user agent. Some of the reviewers are pretty uneducated, let me explain that some settings in this addon HAVE to break sites by design. It's how the internet works.

Amazing tool, I love it. A must have. The only addon that also fake javascript. But setting the about:config is not automated. Please make a tweaking tool for this.
