Spoof websites trying to gather information about your web navigation to deliver distinct content you may not want

Image from store User-Agent Switcher and Manager
Description from store 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: https://www.youtube.com/watch?v=4M6_Zc4o1MQ 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 For more info and general bug reports please use: https://add0n.com/useragent-switcher.html For technical bug reports please use: https://github.com/ray-lothian/UserAgent-Switcher/

  • (2023-05-11) George Ngigi: Just perfect, for my use case.
  • (2023-04-27) Elnaol: The best!

  • (2023-04-01) ana cris: good
  • (2023-03-28) Sven Barthel (scysys): Bitte einmal eine Option einfügen die es erlaubt den UserAgent alle X Sek/Minuten automatisch zu wechseln.
  • (2023-03-20) Dee Gee: Simply didn't work. Websites weren't fooled for a moment.
  • (2023-03-15) ylluminate: This seems to perhaps be the most flexible of the User Agent switcher extensions available, thanks for building it. It does need some work to make it have more up-to-date agents available, or make the user interface more clear to show how to define a new user agent very easily. For example, pasting one into the current extension dropdown is not clear whether it will work properly or overwrite an existing one, or so forth. There should be a "Custom UA String:" label or such to make it clear for readily defining one.
  • (2023-03-12) Chris Vydas: Poorly done, bugs, causes severely high CPU usage only with this extension enabled. Couldn't uninstall fast enough!!! If you're like me and wondering why all of a sudden your browser is hanging and crashing, look no further... This extension is the culprit
  • (2023-03-07) Cheat Game Mobile (Tứ Bảnh 2K3): Tiện ích rất tốt, có thể giữ tự động giữ nguyên trạng thái useragent trên mọi trang web hoặc trang web chỉ định, và đặc biệt là có thể thay đổi giá trị useragent tùy ý. Mình đang dùng cái này để lừa chatbot Bing AI hoạt động trên Chrome thay vì Edge
  • (2023-03-06) Ladia Zhang: custom模式似乎有bug 打开https://www.xinminlan.cn/ 时会重定向到https://gd0045.xyz/ 在disable spoofing 添加xinminlan.cn 也没有作用还是重定向到https://gd0045.xyz/ 只能切换回黑名单模式 才不重定向
  • (2023-02-28) John Doe: absolutely amazing.
  • (2023-02-20) Novia Lolopaking: thank you
  • (2023-02-20) Mila Karmila: good
  • (2023-02-15) jeremiah rempel: Easy to use interface with Every option I could ever need. Was the second one I tried with the most downloaded one having one of the worst user experiences I've seen in years.
  • (2023-01-04) Fredrick Dave Santulan: It's the only agent switcher that has Edge browser option I've seen.
  • (2022-12-17) ・ ・: 一部の官公庁や銀行のWebサイト、IEしか対応していないものも2023年だというのに未だにあり、これで突破できるので大変助かります。有料でもいいレベル。
  • (2022-12-15) mindfulStats: На данный момент лучшее расширение по смене юзер-агента
  • (2022-12-06) hamed noice: DL2
  • (2022-11-27) magnetique12: I need to remove 2 stars because of annoying update tab open itself!
  • (2022-11-25) Арсен Буттаев: Хорошее расширение, работает. Недавно, правда, обнаружил, что перестал грузить WhatsApp Web (https://web.whatsapp.com/). Браузер — Chromium, обновил до версии 107.0.5304.107, с предыдущей 105.* было аналогичною. Пришлось добавлять домен в список исключений.
  • (2022-11-24) Elvillio: Hands down the best spoofer out there. I have used multiple spoofers all this time, only this one works! Plus it has the best UI! The Whitelist/Blacklist option is an amazing feature and extremely useful. Well Done.
  • (2022-11-15) Daniel: Got this to watch prime streaming in HD on chromebook, tried one other user-agent extention that didn't work after lots of messing around. This worked first time, and I prefer the UI. It is a bit confusing for a second or two, so can understand the other reviews saying they didn't like the UI but I thought it was great, as I said, takes a moment to work it out, but once I had, applied the first windows pre-set, refreshed tab through the UI, HD immediately. Thank you!!
  • (2022-10-24) Matt Saywell: Best user agent switcher out there, the whitelist/blacklist is especially useful
  • (2022-10-21) Nguyen Duy Tan: I use this for longtime. Good but at this time this extension is effected to my facebook. When i enable this extension. My facebook keep showing blocking content (Rate limit). So i think extension use facebook token for spamming? I have no idea why. But when i disable and logout/login my facebook is fine. If not logout it still keep showing the error/block message from facebook.
  • (2022-10-16) Ilja: Super useful and loads of options.
  • (2022-01-18) Peter Buick: WARNING: Seems to force chrome to 32 bit??
  • (2022-01-15) Monolithic: работает. Chrome 90.0.4430.212 (Portable Edition)
  • (2022-01-06) MERT BENLİ: İşini fazlasıyla yapıyor. Diğer eklentilerin aksine daha fazla seçenek sunması harika.
  • (2021-12-29) Its The Scorbo: This is a very good extension, and it supports almost any browser and OS I can imagine! The only thing which I noticed that it doesn't have is the Nintendo 3DS browser.
  • (2021-12-28) Ado216: Works as it intended to, you have a huge variety of os's you can pick.
  • (2021-12-28) Logeshwaran L.K: Best User agents
  • (2021-12-14) Jacob Holmes: BIG WARNING - "CUSTOM" MODE **ALWAYS** APPLIES! If you switch in options to Blacklist or Whitelist mode, ***anything*** you have entered into "Custom" mode will ***STILL APPLY***. That's not documented, or obvious. So if you change the user agent and want it to apply to sites you have in the "Custom" mode box, you will have to DELETE EVERYTHING you have in there (i.e., replace with {}). I paste it into Notepad/text file, then paste it back when I want custom mode re-enabled.
  • (2021-10-26) Сергей Травкин: спасибо. работает.
  • (2021-10-02) Alexis Hayat: I'm making a user agent parser, and after testing a few more extensions, this one is the most complete. It's very pleasant to be able to change our user agent this easily^^ Thanks ;)
  • (2021-08-15) lindgrenfabian: Perfect. Stops google from bugging you about using Chrome.
  • (2021-08-10) space Explorers: Extensions doesn't actually work. browser information is being leaked. attempted to watch tv on linux and got a "Linux not supported.." switched the "agent" to all variations of "supported OS's and browsers" but it still reports it doesnt support linux... So I installed extension on windows, chose a linux version of a browser and it loaded just fine.. extension doesn't work completely.
  • (2021-07-03) Björn Draegert: It might work with some sites, but my company's website still always loads its tablet version on my Pixelbook, no matter what I set the agent to (but of course it works without a hitch on my Windows PC). I also deleted all cookies and other temp files, still to no avail.
  • (2021-07-02) Anton Grachev: Для меня лучшее и удобное расширение по смене user-agent, которое работает и имеет большой выбор смены профиля по разным шаблонам и даже версиям. Отлично
  • (2021-07-01) scott truskin: Very Nice ! Have a lot type of navigators and works fine
  • (2021-06-28) Mark B: In terms of user agent options, it's got the most and it works like a charm.
  • (2021-06-14) Coolblind: Tried multiple "user-agent" extensions, only this one works for me for some websites I need to visit. Nice work, thanks!
  • (2021-06-02) sora MSK: 挺好用的
  • (2021-05-26) nice
  • (2021-05-22) Ярослав Чудаков: Спасибо! Наконец то дурацкая надпись в ВК - обновить или поставить Атом убралась.
  • (2021-05-17) spee admiral: It's usefull. WHAT'S MY BROWSER?
