Rated 5 out of 5 stars

Sehr gutes Add on, das wunderbar funktioniert. Man muss allerdings das Symbol manuell in die Symbolleiste ziehen unter Ansicht> Symbolleisten> Anpassen findet man das Symbol. Nach dem Downloaden der User Agents von der Forenseite auf die verwiesen wird, kann man sein Betriebssystem erfolgreich verbergen. Man kann auf diese Weise Programme herunterladen die normalerweise nur zur Online-Installation angeboten werden.

Works on SeaMonkey 2.8 Rated 5 out of 5 stars

... after editing the install.rdf file. It would have helped if the author had commented the sections in the install.rdf file with the plain-language equivalents of the cryptic security signatures. Download the .xpi file here by right-clicking on the "Add to Firefox" button. Unzip the .xpi file with Winzip or other archive manager and open the install.rdf file with a text editor such as Notepad or gedit. The SeaMonkey entry is identifiable as {92650c4d-4b8e-4d2a-b7eb-24ecf4f6b63a}. Change the maxVersion value from the default 2.0.* to 2.8.* or 2.9.*, re-zip the archive and change the file name extension from .zip to .xpi. Open the file with SeaMonkey and it will install without a problem.

User Agent Switcher doesn't make your Mozilla-based browser work like Microsoft Internet Explorer, but it will fool "snob" sites that don't even want to let browsers other than MSIE in the door. I can accept that my browser may render the page differently, but please don't bar entry completely. Useful tool.

In manchen Fällen nützlich Rated 4 out of 5 stars

Damit kann man z. B. die alte Version vom Webmailer von 1&1 aufrufen. Diese ist viel flotter und werbefrei. Auch gut für Leute die sehen wollen wie ihre Webseite auf manchen Handies dargestellt wird

Muy Bien, me ayudo mucho

If you don't see it look up! Rated 5 out of 5 stars

majikbocks and others having the issue with the icon not appearing in the add-on bar it defaults to the Navigation bar for some reason. So look to the right of the address bar.

So far zero. Installed it and nothing shows up in toolbar. developer bar shows up but not this

Rated 5 out of 5 stars

Best of class add-on. Clean, simple, and gets the job done. Also, to those complaining, the user agent list SHOULD be short and limited to the most commonly used agents. The more people spoofing the same browser that you are spoofing, the better your anonymity.

Meh Rated 3 out of 5 stars

Odd interface, very out-of-date UAs, not convinced it's even working. Didn't crash FF though. I'm deleting it and trying something else.

more user agents please... Rated 2 out of 5 stars

Ok, but a few more user agents should be available by default (at least android, opera, chrome, IE, safari etc). With only iphone and IE, it's too limited, and I don't want to set up the user agent strings by hand (I couldn't download the list of user agents to import).

Works but has a few bugs Rated 3 out of 5 stars

When it's working it works well but there are some bugs with it. Your user agent will get reset to default after every restart unless you add an entry to about:config. Create a new boolean entry 'useragentswitcher.reset.onclose' and set it to false. That will fix the reset problem.

Then there's the issue of Agent Switcher not working at all sometimes. For some reason Agent Switcher won't work on my main profile for FF 11. It installs but the user agent list is blank and nothing happens when I import a list and creating a new user agent doesn't work either. I had to create a new profile for it to work. On FF Nightly (FF 13) I never had any problems. Strange.

The UA list that comes with the addon is pretty weak. I don't know why the developer doesn't include a full updated list. It wouldn't be hard to do. I went to to download a fairly recent updated list. So this addon can work but be prepared to tweak it if necessary.

Fine Coding Rated 5 out of 5 stars

Five stars although I don't really understand the benefits of switching user agents aside from a privacy perspective.
BUT- it does work- and very smoothly at that. Hence 5 stars.

Rated 4 out of 5 stars

Now there is an addon which works per domain based, if User Agent Switcher could use a code like that to work the same way is would be perfect.

Rated 5 out of 5 stars

One of the most important add-ons for me, a great tool against sites that do incorrect user-agent spoofing.

便利 Rated 4 out of 5 stars



Good, but... Rated 4 out of 5 stars

please make the setting persist over browser restarts.

I would also suggest to slightly rename the Menu entry, something like "User Agent: $agent" (or "UA: $agent"). I think this is a bit less confusing.

Two simple minor changes which will make this addon perfect for me! :-)

Nice Rated 5 out of 5 stars

I use it since FF 3.X, and i'm already at FF9, without any problems.

Epic when you work with Mobile Web. Of course it does not emulate the html rendered by the devices but the main use is to test the behavior of some application in lots of user-agents.

Somehow I installed this on Firefox v9.0.1 and it works perfectly fine, helping me to download HDMOV movie trailers from Doesn't slow the browser down, the button looks fine with my theme. Handy addon.
