User-Agent Switcher and Manager
Spoof websites trying to gather information about your web navigation to deliver distinct content you may not want
Usage example: You can alter your user-agent string to indicate you?re on a mobile device if you prefer seeing mobile versions of sites so they load quicker.
--
This extension allows you to spoof your browser "user-agent" string to a custom designation, making it impossible for websites to know specific details about your browsing arrangement.
Video overview:

Notes:
1. You can easily set custom "user-agent" strings from the toolbar popup
2. The extension uses a two-factor technique to mimic your default "user-agent" string, which is the most reliable method
3. The extension does not use any resources when it is not spoofing the user-agent
4. The extension enables user-agent spoofing on specific domains only; it is conversely possible to exclude certain domains from spoofing. Check the Options page for more info.
5. You can set per-site user-agent strings
6. There is an option to randomize user-agent strings.
7. It is possible to set user-agent string for a single window; you can have a separate user-agent string for each browser window
8. It supports modern browser identification mechanisms such as "Client Hints" headers and the "navigator.userAgentData" object.

Please update or add actual User-Agents for Safari (iOS/Macos) https://www.whatismybrowser.com/guides/the-latest-user-agent/safari
Why the hell does this extension keep opening tabs to its update notes? Buzz off...
App is great been using since 10years There is no option to set deault useragent you provide in option settings, where i just want to set only one website as internet explorer 9.0, i tried to set but always getting json error even after editing the sample insert Add Dropdown to choose from the list abailable in options/settign page
thanks i want to change the chrome version cuz want to play some flash games
I have installed to use on TWITCH, but all the ADS from TWITCH still apearing, and it doesn't matter if the streamer has been on camera for 1 hour or its just starting the ADS appears. ((20th june, 2025))
amazing
did what i needed it to do if you use linux this is a must have for things that you need to download with windows
Did the job perfectly with one click. Usage situation was web.whatsapp.com who told me that with my browser I can´t access it. With this tool I could with 1 click. Great!
cant pass cloudflare =\
only "chrome"...
Nice bro ♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
3 star since it doesn't pass the cloudflare verification. Please fix it.
Perfect, so many UA settings, thank you.
Works great for me.
Perfect. The only one I know that can automatically revise the "sec-ch-ua-platform" http header. It even adaptively exposes "navigator.platform". Good job, thanks.
does not work on facebook
work great for me
自定义程度高，可选ua多
Does not work for me, in Edge if I try to track a UPS shipment, it never loads, I try to select Firefox and refresh the tab, nothing changes.
Basically works but hard to use.
Please Revert back your original App Icon.
Simply the best.
It is very helpfull BUT i can not set custom version of fake browser so I can not use service with existed presets due to outdated version browser it says.
Recent updates to this extension has completely prevented Facebook.com from functioning. This extension is completely useless now............It has broken Facebook entirely.. Worked great while it lasted.
Does what it's supposed to do, not to complete perfection, but i think it's deserving of a 5 star rating.
Hello, please update the user-agent to the new ones! Already, a long time ago, all browsers, very much updated! Good luck and happiness to you)
works, however, it breaks some pages, please fix this, thanks.
Nice, but I can't get it to automatically work on newly opened windows (even if the main / host window has it enabled)
superb
Best in the business
Does what it says well enough
I don't understand how people still using this one, it left a very big bug, easily can be traced by any bot detector, added amd64 on all useragents, sounds funny, this should match with current architecture or a way to select on extension based on cpu
Flexible and fast transaction Cool wallet
The best one for adaptive user-agent settings
НЕ Работает, от слова СОВСЕМ !!!!!! Slimjet Версия 19.0.9.0 (на основе Chromium 66.0.3359.117) (Официальная сборка), (32 бит)
brilliant for making adblock work on youtube again
God Damn!
Has a lot of user agents and filters. Works wonders if you want to test a bunch of different browser version without having to look up user agent strings manually.
It doesn't work all the time. I just tried logging in on Twitch in Chrome and got an error about unsupported browser even though I had the latest version. So I switched my user agent to Firefox and I still would get the login error. Same with switching to Safari user agent.

Worked for me when others would not. Works on the one website I need it on. Doesn't seem to have much of a footprint otherwise 👍. I will say that this is the first program / app / extension in a very long time I wished had an idiot user mode. I feel a bit like a Cessna pilot trying to fly a 747 with all its custom modes, white lists etc. But since I seem to have gotten the result I wanted (I can log on the website that told me no Vivaldi) while not applying itself to other websites (at least the test sites I've checked) I'm a very happy customer. If I stay that way I'll try donating.

1. Doesn't work with CloudFlare, makes visiting websites proxied by it impossible and we are talking about millions of websites. 2. The internal database of User Agents is rarely if ever updated. 3. In rare cases when you visit a website, the current tab simply freezes, the CPU use spikes to 100% and nothing ever happens. You just cannot browse it until you disable the extension.
