  • this addon has helped me with many tests. thank you for this.
  • This is a good estension because it spoof others navigator values in about config. I found a bug, after choice a browser prefecence do not update the vendor value. Some browser like Google Chrome have a vendor "Google Inc." or Opera Browser have vendor "Opera Software ASA", firefox have vendor empy "". I suggest to add the spoof of vendor like others navigator values. This is one of few estension that really spoof in serious mode because there are many value to change not only useragents to spoof a browser. Take into consideration the idea to change the value of vendor because it is important and some browsers communicate it to the sites to be identified. Have a nice day.

    Update 06 December 2018.
    1) I found some incorrect value in this estension, I added the complete image of all navigator values for firefox and Google Chrome, please adapt the estension to show correct value because some site can block browser with incorrect navigator data.

    2) There are a bug, when you choice some useragent must be show oscpu null "" otherwise show original os in the machine. The user agent setted show a user agent (in my foto android) but oscpu (in google chrome is always null "") show real os (in my chase windows 7).
    ThIs is a bug important to fix because show a conflict of the os from the user agent setted and oscpu grabbed via javascript.

    I look in the estension there are a javascript file to set the navigator to show after choice an user agent, please look the 2 image added to adapt the estension to show correct values, i added image from firefox and google chrome with complete navigator list values.

    Thanks your work.
    Thank you for your feedback! I've created an issue for the mentioned problem at https://gitlab.com/ntninja/user-agent-switcher/issues/52.
  • Bloated and slow. Another addon, "User Agent Switcher and Manager", which do exactly the same, is faster and more than 20 times smaller!
    Yet it doesn't spoof the other `navigator.*` properties amiright? Over 90% of the size of this extension is a stripped down version of the Browscap User-Agent capability database that we use to infer the required extra information based on the given User-Agent-String. Not trying to convince you or anything, but I thought an explanation of why this is happening may be in order. :-)
  • Dude you just stole my heart with this addon. This is working perfectly as I wanted to. I want to add more User-Agents and OS and others for that I need your kind help. I have emailed you to the support email listed for this addon page.

    *** I'm seeking for your attention dear admin of this addon sir ***

    I need your kind help to add more User-Agents, OS, Versions etc.

    Can you publish an Updated Version soon? Or else You can help me to add manually?
    I'm really not aware of user-agents for different browsers and OS.

    *** Waiting for your response ***
    Sorry for the late response, I didn't see your message earlier unfortunately. The list of shipped User-Agents was recently updated. I do not plan on extending the shipped User-Agent list, since maintaining it is quite a bit of work and don't want to add any obscure entries.

    You can, however, add you own entries in the settings (Menu → Add-Ons → Extensions → User-Agent-Switcher → Preferences). In order to find the strings you need I'd suggest looking at http://useragentstring.com/pages/useragentstring.php which has a very big list of those (they are not always up-to-date however).

    Sincerely, Alexander
  • Unlike some other apps I saw suggested from Firefox & others results from Apps search & Google search this 1 actually was to UPLOAD images to certain sites like Instagram (90% of the others were to download images already posted on sites by other people instead of using screenshot apps, almost complete opposite of what I was searching for). And even better you explained how it works & how to use it RIGHT in certain internet servers. That helped a lot more than what I got from Google (lol. Some results were even outdated/impossible to use now). This saved me time & even money because now I don't have to go buy a smartphone just to actually/fully use a website (or 2+).
  • Seems to be one of the more frequently updated UA changing extensions. Keep it up!
  • Love it that you can add custom strings (just use Ctrl + V to paste). It works very well. It doesn't fool the Firefox add on site, but I see this is a Firefox policy, and the developer has provided a work around. This is a terrific, easy to understand and use add on. It does fool Google and all the user-agent testing sites.
    Thanks for the review! Unfortunately this is a limitation of the WebExtension API: The Firefox add-on site is blacklisted from manipulations of extensions due to browser policy. I've added this (and a manual workaround) to add-on's description.
  • Tested this addon against sites like: https://panopticlick.eff.org/
    As you will clearly see when you test it for yourself, it does not work.
    Set it to windows / IE : here is my test result
    User Agent

    Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko
    as you can clearly see it does not work.
    I'm not sure what you are complaining about, but the above is a “Windows 7 64-bit running Internet Explorer 11 32-bit” user-agent. I see nothing unexpected with this result.
