  • Using Firefox 52.5.0ESR and Java 8 Update 151 ... I can not get this web site to load the crossword puzzle.


    It will work in Windows 10 using IE11 and was working just fine on Tuesday Nov 21, 2017
    It has been reported to the site manager but they have not responded or corrected the issue.
    I tried it using a few choices in User Agent Switcher, but it still did not load. Also, any chance to make
    the UAS Button smaller ? ? ? It takes up a lot of room. Thanks
  • It also allows you to create custom UAs! (Not mentioned in doc but IMO important)
  • Very useful. Good to have. Only gripe is to add an option to change user agent every number of page changes. Like if that's set to 1, it will change the user agent every time a page is refreshed or a link is clicked. If set to 2, then after that happens twice user agent is switched. This, I think, would be a good addition to the random option.
  • nice agent switcher but it badly need a whitelist that set agent to default on selected website
  • This add-on changed my useragent but also broke other add-ons. External video player was one of them..it worked after I disabled UA switcher. Stable Firefox for Android..Note5.
    Edit 1. Another add-on that seems to have abandoned stable Firefox on Android..I've noticed the trend. :-\ This works fine, so far, on Firefox beta. Please disregard one half of the 3★s I gave the add-on. It should be 2½★s since it only works on half of the Firefox browsers I use.
  • Esta es la que va. Se puede editar completamente la lista. Nada más le faltaría poder importar y exportar las cadenas de agentes de usuarios y ahí sí le doy 5 estrellas.
  • it works, but..
    does not override appVersion, and platform + oscpu are parsed incorrectly for 64bit OS (they are displayed as 32 bit/x86/i686 instead of x86_64, etc..)
  • Ist gut, alles funktioniert
    Everything okay, does a good job.
  • ok
  • Super teil, wäre nur schön wenn man verschiedene Agent-Profile für verschiedene Webseiten spezfifizieren könnte.
  • Use a specific user agen for a particular site, automatically switch to a specific user agen when visiting this site。。为特定的网站使用特定的ua,当访问这个网站的时候自动切换到设定的ua。
  • 这是5星吗
  • 当指定一个网站的ua后。当访问这个网站时候自动切换到设定的ua,而不是去手动修改。谢谢
    Sorry I don't speak any Chinese…
    Are you refering to per-site User-Agent switching? That is currently the most asked for feature. It will be implemented once we know how to show it in the user interface. It shouldn't take too long, but we will see.

  • Please add Windows/Firefox string too and would be even great if there were Windows 7 and 8 versions too.
    Thanks for your feedback! However I'm not quite sure what you mean: Isn't the first entry in the "Desktop" section "Windows / Firefox 56" for you?

    Adding new User-Agents for different Windows versions is unlikely to happen as they are IMHO not sufficiently different from the existing entries to justify making the list longer than it already is. There also is currently unresolved question on how to keep the list from becoming stale without too much reoccurring labour.
  • I have a FF 52.0.2 on the Windows XP. I got this plugin and set my own UA string
    "Mozilla/5.0 (Windows NT 5.1; rv:56.0) Gecko/20100101 Firefox/56.0" (Actual version of FF today).
    All web-tests was correctly show me it ("User-Agent: " header), but on the Firefox Download Page
    https://www.mozilla.org/en-US/firefox/all/ still show me "Your Firefox is out-of-date."
    Console (Ctrl+Shift+K) output on the "Navigator.Useragent" do not show my string, still write
    original "Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0".
    Thanks for your feedback!

    Unfortunately there is a certain list of “restricted domains” that extensions cannot access. Based on some quick tests with IceCat (Firefox ESR fork) it appears that on that version of Firefox the entirety of the `mozilla.org` domain was on that (undocumented) list. In recent versions of Firefox (at least Firefox 57+, but probably before then as well) however, only `addons.mozilla.org` seems to be restricted (and this fact *is* [documented](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Content_scripts)), so what you're trying to do would work there. There is nothing I can do about these restrictions on the extension side, unfortunately.

    If you need to change the User-Agent even for restricted domains in any version of Firefox please instead open "about:config", create the string value "general.useragent.override" and set it to whatever you like. Doing so will break *User Agent Switcher* but should work in your case. :-)
