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/

  • (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

  • (2021-05-17) spee admiral: It's usefull. WHAT'S MY BROWSER?
  • (2021-05-16) CHIRAG SINGHAL: useless for me.
  • (2021-05-09) bloodys spammers: 💩 USELESS ON YANDEX MOBILE BROWSER! 💩 🤬 OUTDATED UA!!! POOR UI! 🤬💩
  • (2021-04-28) C Z: 非常好
  • (2021-04-17) Mucahit Turel: It works great!
  • (2021-03-17) Ali R. Mo.: Works perfect, UI is a little confusing and too many clicks to activate but it works!
  • (2021-02-28) Ulti P. Uzzer: How do you get new agent strings for it, as of March 2021 the Win 10 user strings (which I use to spoof Win 7), the Chrome version number is now 3 version behind.
  • (2021-02-19) Tracy Hieatt: Worked on a site that doesn't support Opera.
  • (2021-02-09) nocturnal digitalist: UPDATE - Now most user agents are outdated and sites recommend switching to latest browser despite using latest user agent. Sites like google, google docs, nimbusweb, evernote, simplenote, amazon prime video shows this. i request dev to update actually if he has updated it only in numbers not in actuality. Also many user agents are not detected as such when you search online and visit sites that does "user agent test" or "what is my user agent" "my user agent". I went to many sites and only dev recommended site works, others dont. Also add option of adding our own user agent. Please update. Probably the effective but only at times by large it doesnt work if you are using other chromium browsers apart from Chrome like kinza, cent, edge, brave, opera, vivaldi, or any other. If you have set a particular user agent as default, chances are it wont be same if you open or restart the browser after some time or whenever you are opening your device. I set firefox on macos but after I restarted the browser, it showed my real agent. Also while browsing, some sites know of your real user agent irrespective of what you have set via this extension. I request dev to check the extension by himself and then re-release it as it is not stable or reliable enough. Also the extension icon is not visible in the extension bar. Plus, a lot of user agents are missing or outdated looking at many new versions of software and OS are coming up recently. Also I used it on my mobile browser like kiwi browser, iceraven browser and firefox fennec browser but doesnt help to hide or get to the site that doesnt work through real user agent. Plus there is no easy way to contact the dev or vice versa.
  • (2021-01-02) Wayne Gavin: yaaasssss
  • (2020-12-10) Cristian Viorel Pasat: Works!
  • (2020-11-15) Écrivain: DON'T use that scam extension. Doesnt pass this test : https://webbrowsertools.com/useragent/ --> UA from the normal way isn't spoofed so websites know you're trying to hide your UA, so you're easier to track !! The link in the extension is not exactly the same, it bypass the "normal" way of getting your UA. And why the spoofing is disabled for Google ??? Don't use this scam !!
  • (2020-11-10) Hady Rashwan: The best user agent switcher
  • (2020-11-07) 風呂先路線: The most switcher with the least holes I've found... it does have one hole, but it's not frequently exploited.
  • (2020-10-17) Heavy NewMan: Excellent, even spoof in java scripts - https://browserleaks.com/javascript But it would be even better if there was an option for random spoofing.
  • (2020-10-16) LTNS XD: This is absolutely what ive been searching for 5/5 amazing add on
  • (2020-09-30) D Dmitriy: не работает на chrome-49!!!
  • (2020-09-15) Neongreensniper Pie: Looks good, but does not work with the browser brave it always says connection failed when trying to download it.
  • (2020-09-10) Ray Foss: Super close to being amazing... but has a HUGE flaw... does not modify the navigator before page loads. If you can't figure out how to stop the browser leaking your useragent everywhere... leave a disclaimer about it. This is a huge privacy leak. https://webbrowsertools.com/useragent/
  • (2020-09-05) 126 F: 超级好用,有些只能微信打开的网页,win10 edge浏览器改UA以后也能打开。而且ua特别多,但有些不是最新的,希望可以及时更新!
  • (2020-09-02) Sharodshahi Al-Amin: The best user agent..... seriously love it.
  • (2020-08-02) Zot 1: I need it to use google docs on edge. I could not live without it! Thank you so much for sharing your time and talents!
  • (2020-07-03) Shamim: It's the best user agent switcher!
  • (2020-04-08) Vera Johnson: better than other user agent
  • (2020-03-27) Sébastien Sarmiento: Après avoir testé plusieurs autres extensions du même type j'ai trouvé celle-ci qui convient parfaitement. Complète et super intuitive! Merci After testing several other extensions of the same type I found this one to be perfectly suitable. Complete and super intuitive! Thanks
  • (2020-03-23) Mikle Talalaevskiy: How to use Instagram chat on PC or MAC? Use this extension and set it to Android for whitelist for instagram.com and enjoy instagram's instant messaging from the comfort of your keyboard Yours, DayDreamer.
  • (2020-03-18) Fatih Kurnaz: Wowwwww
  • (2020-03-04) Aurora Fingon: Allows you to set a user agent for specific sites only, which is exactly what I wanted and couldn't find in another extension. You can set custom user agents by editing the userAgent box in the extension window with the user agent string of your choice (googlebot, ect). 4 stars because this function is not clear and would be better if this was a default option.
  • (2020-02-28) Chris McFarland: Works great. Lots of OS and browser versions to choose from.
  • (2020-02-28) Hosa: How can u call yourself a user agent switcher when u dont have the basic ones? Search engine bots!!
  • (2020-02-10) 玄影: 能支持一下中文吗? 谢谢
  • (2020-01-16) Tim Müller: Perfekt! Genaue Auswahl, welcher Browser, welche Version, etc. pp. (...)
  • (2019-11-29) Gabriel J. Dias Pinto: É esse
  • (2019-11-28) Bai White: very good
  • (2019-11-10) Shroom2018: This is the only user-agent switcher that is not made by a team of idiots! If you are using another Chromium-based browser but are disappointed by what Google is doing to make you use Chrome, stop wasting your time and download this ASAP!
  • (2019-11-07) DrHitman27: Works on chromium browsers, so you can fix some sites that think that you use non-chrome browser.
  • (2019-10-28) Marcus Deubel: Does not work as expected. Whitelisting does not work.
  • (2019-10-15) John Canny: 提供的UA非常多,果断好评!Excellent! Rich in variety!
  • (2019-10-01) Anton Gustafsson: Works good, wish it could change at specific intervals though.
  • (2019-08-22) Music Mayer: Contains modern user-agent strings (I do not have time to figure it out and build them myself). Solved my problem with Yahoo Mail and Chrome 49 and Mac OS X 10.6.8. YAY!
