I recently started testing this extension. The last version "improved" the extension so much that it stopped working. It doesn't matter what user-agent it shows - browser tests always return the original one.

I started to get blocked by websites as a bot while using this addon. Do not recommend.

This doesn't work at all, with any configuration, and hasn't seen an update in over a year. Version 0.6.1.1 is available on other extension stores, and I would package and install this myself, but there are no releases on GitHub.

Why it's so complicated to JUST SET USER AGENT TO SPECIFIC SITE?

Graphical glitches while add-on was installed and link addresses were showing up in the bottom corner without the /s? Not sure what kind of bug this is? Removed the add-on and everything is fine now. Why would an add-on that is used to spoof the User-Agent mess with graphical and character memory?

Doesn't add any buttons or anything to any menus. The "how to" is a massive wall of text. And the settings are far too complex. Where is the one click "make this website not be dumb" button?

Installs junk and you can't opt-out, beware

No use.

unstable with deezer.com on firefox 123 win64

does nothing in the latest few versions of firefox

If this add-on has a UI, it completely escapes me.

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

Does nothing with Firefox 120/Ubuntu

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.

Does not work for me on https://webbrowsertools.com

All those websites with cloudfare security cant be accessed with this addon enabled. Wasted hours of time searching for the reason.
