Opciones muy limitadas, cadenas de agentes de usuarios desactualizadísimas, sin opción para importar y exportar.

Useful, user friendly and beautyfull user interface

This add-on save me many times but I think is better if integrated on the core of Developer tools...

the user agents should be updated but other than that it's near perfect

Works perfectly, however, as other people have said, it would be awesome if the browsers were up to date by default.

Another great feature would be specific OS, like Ubuntu, Windows 7, XP, Fedora etc, instead of Linux/Windows only.

The versions for Browsers and Operating Systems are outdated:
Mac OS is 10.10 in the extension while current Mac OS is 10.11
Chrome is 41 in the extension while current Chrome is 62

Search Engine agents are missing, Editing is broken.
I stopped using the add-on, it is still installed as I'm hoping to see fixes in next versions.

It would be one thing if all the agent strings were actually current. But this coupled with the inability to edit (broken) renders this completely useless to me.

1.) You can't set custom user agents
2.) Altering the user agent string doesn't work, user agent won't change.

The graphics could be a little better and "native" looking.

Thanks!

Works quite well and is easy to use

nice prog :)
but will it update automatically the faked devices, browsers and OSs?

My mobile device is still Android Nexus 5 - this is too old for many sites...

How can i set UAS to the newest devices?
thx

Nice extension with more accurate/actual pre-defined strings than other Add-ons (but still far away from being actual, e.g. Firefox 31.0 where meanwhile 53.0 is the actual version). When updating a User-Agent String myself via Edit button the changed string is not saved. 5 stars when this issue will be fixed.

Does what it says, very intuitive interface.
Updated UAs would be nice though (currently at least 10 versions too old for chrome)

It's quite useful, but it's very simple should have more options to configure it to a person's needs properly.

- No way do edit browser details. Edit function does not save any changes.
- No way do edit Operating System details. Edit function does not save any changes.
- No way to add custom browsers.
- No way to add custom Operating Systems.

A useless extension.

Uninstalled.

Very simple. Very Good

Is it possible to add user agents of the Search bots like bing and google?

I dropped the ancient Useragent Switcher for this addon. I like that it's easy for beginners and it keep it's setting after browser restarts.

There's one major annoyance.

There's only 1 version of the OS and browser you can select.

If for example we could pick between Win XP, Win Vista, Win 7, Win 8 and Win 10 and Firefox 2, Firefox 39, Firefox 52 etc.

This addon would be perfect.
