• (2025-01-30) Jay Goldberg: Unfortunately this is not quite there. There's not a simple text field to paste a string. If you paste it a string, you go back to edit it, the field is empty instead of containing the previous setting. It has an annoying pop-up that asks you "are you sure you want to switch to the default agent". Why?
• (2024-07-21) Pratyush Sinha: It solved my issue , many times the services you are using over the internet are not compatible with OS, this extension will come as a remedy . Great Tool
• (2024-05-05) Marie Hekel: its not perfect but it does the job better than most others ive tried. I use Chrome and Opera GX regularly and sadly many sites do not recognize Opera GX (they should!!!) so have a user-agent is a valuable tool. and having so many options is great for development purposes as well. thanks!

• (2021-11-08) Nocturnal Owl Digitalist: I dont dev is interested in making useful addon. All of this addon's user agents are outdated. Majority of site shows "This version of Google Chrome is no longer supported. Please upgrade to a supported browser. Dismiss." Please update the user agents. Also dev still doesnt know the newer edge as their is old edge. I have meanwhile reported the addon to google for removal if dev is not going to update and latest user agents. On firefox, it works well if not great.

• (2021-10-03) HAL Gianotts: Provati diversi, questo è l'unico che ha funzionato. Ottimo!
• (2021-09-08) Gottfried Franz (Esoist): Funktioniert einfach nicht mehr, war vorher gar nicht so übel!
• (2021-09-01) ana glaucia Monteiro: ótimo, pratico e eficiente
• (2021-08-13) _ Vogelmann_: Does not work correctly. Though most client user-agent proofing pages show the the correct spoofed header, this extension actually sends a MIX of real and spoofed user-agent headers! I logged all the headers sent from my Chrome browser while with 2 tabs loading different pages. Here a clip of client server communication (removed other headers): CONNECT / HTTP/1.1 Host: manytools.org:443 User-Agent: Mozilla/5.0 (Windows NT 6.3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome....

• (2021-06-26) Joseph Fontana: As a Linux user, this website did not let me download a Windows program, (although I could run it with a program called Wine) This extension is a life saver, until the Windows program didn't even work :/ Still works though, and I will probably use it in the future too.

• (2019-06-23) Shrayus Masanam: Best UA Switcher out there.
• (2019-03-25) Scott Grayban: I gave it a 4 star for one simple reason... you can set it for a single tab and/or set urls for specific UA. But it's still better then what's out there for the most part. It certainly allowed me to use web.skype.com !!

• (2018-12-28) Andreas Toth: Illogical organisation of operating systems and browsers. Should be simplified by breaking down the three rows of mobile platforms, browsers, and operating systems to only two rows with the top one being the operating system which includes Windows, Linux, Android, macOS, iOS, etc., etc. The second row would then list the possible browsers for the selected operating system. There is absolutely **no** need for a third row listing mobile platforms as mobile platforms are operating systems! Note also the order of the rows, operating systems should be listed and selected before the browser since the operating system determines the browsers that are available under that operating system. I do hope this gets tidied up in a future version since I wish to use this extension as it is the only one that I can find that exist for both Chrome and Firefox and supports overriding per domain. In addition there is no "default" option, i.e., an option that returns the real user-agent. This is a must!

• (2018-11-25) Chloe Whitten: A must-have for chromebook users, as many developers don't take into account this OS. Now you can easily switch! Additionally, other user-agent switching apps haven't been updated in a year, so their browsers are outdated.
