great experience

The option to change the global user agent "Apply (container or window)" doesn't work even on the website "webbrowsertools.com". Tested on Firefox 121.0.

Domain whitelist / blacklist does NOT work

when your bank has stupid expectations of updates switch your agent. Else run a virtual machine

Great at bypassing browser discrimination

Does nothing with Firefox 120/Ubuntu

f you youtube

To anyone having an issue with cloud-flare looping verification box, go to user agent options>white list mode and add www.cloudflare.com. This fixed the issue for me and hopefully for you.

Incredibly unintuitive, and does not seem to work on webbrowsertools.com.

Noticed YouTube stopped working for me today... this did the trick. Didn't have to disable any of my adblockers and now able to load videos, although my computer froze for a moment... thx

update: ok nvm not sure why but stopped working next day...

Completely unusable - interface and functioning is totally non-intuitive. Do not recommend.

Works perfectly, and it stands by the purpose of firefox (and the entire mozilla foundation), being open source. I also love that I can set the ua to something custom like windows 12 with chrome 250.

When i using whitelist mode, this add-ons sometimes mistakely chages my UA for site not on the list. This happens occasionally and triggers Google's security check which warns me that there might be suspicious / mailious behavior in my PC. (i gauess reason would be they find me using different browsers with same cookie in a short time) I confirmed that both fake UA and real UA appear in the Gmail's "recent activity" within short minutes. Oh, this problem is already reported by someone to the github repo: https://github.com/ray-lothian/UserAgent-Switcher/issues/191

It's a nice extension but it's really missing a native "randomize" option where you can select some browsers and OS, and how often you want the extension to randomly choose a new User-Agent for you. I hope Ray can add this soon; which will make it purrrrfect :-)
