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.

Cloudflare, which vast majority of the U.S. sites and 20% of the world's websites use, does not like this app. Also, you ID is simply revealed by the http software you are using. Hence your ID will show as being faked.

Does not work – user agent stays the same.

CPU heavy, and when using isolated tabs, you have issues, it wont go BROWSER WIDE... you have to set per tab n stuff, its a PAI, and ive heard the dev has shut up shop and its full of bugs

Mozilla need to re-review this and give the golden cup to another user agent that can be trusted!

Aside from the white and black lists, this extension also has a list of domains where the UA should never be spoofed. It's never stated that it exists, and I found it out only when I accidentally opened the settings. This list includes domains I was using this extension for, which means that my UA wasn't actually spoofed there. 1/5, many thanks for a privacy leakage for no apparent reason.

it is difficult to master - you need a simple GUI option, where each site offers its own identifier, and not offer to write in a scripting language.
and of course the fox starts using the processor from 1.5% to 15%.

With extension enabled all the sites that use Cloudflare are don't load. Which makes this extension pretty much useless. I hope this issue get fixed then i will change my review.
Edit: Another review reminded me that it "makes the CPU go nuts every 30 seconds!"

This bugs websites that use Cloudflare DDoS protection in the default settings. Funny that their own official website uses Cloudflare protection, so there is probably a workaround but I prefer to just disable it.

Little bit unintuative. Automatically starts only in containers. Doesn't have random UA switcher.

This plugin is either a completely unintuitive piece of crap or it just plainly doesn't work in firefox 113

IDK who "recommended" this extension but they should hide somewhere bc it's a piece of crap which makes the CPU going nuts every 30 seconds!

May be I am stupid but this addon seems like not working.

No clue why Mozilla still recommends this extension. Every time I've used it, it mysteriously disables itself after an unknown period of time. This extension is leaky and it shouldn't be recommended.
