Ever needed to quickly switch between user-agent strings on the fly? Developing a site that needs to work on both mobile browsers and desktop browsers? Sick of some archaic site blocking you because you're not using Netscape 4?
The User-Agent Switcher for Chrome is the answer. With this extension, you can quickly and easily switch between user-agent strings. Also, you can set up specific URLs that you want to spoof every time.
Please note that this does not provide improved privacy while browsing the Internet and that some sites might have other means to figure out that the browser is not what it pretends to be. Running this extension can have performance impact on your browsing experience due to its need to intercept and modify the data communicated to the server.
NOTE: if some sites have problems after using a mobile user-agent, and won't switch back no matter what you spoof, you will need to switch the user-agent back to Chrome *and* clear your cookies for the sites to treat the browser normally again.

It is very convenient for testing when developing mobile environment on PC.
I have 3, so far, websites that don't work on Chromebooks because they require Chrome browser on Windows, which can be resolved with a custom user agent string, "Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko" not natively available in the program but can be added. The problem is the only way to modify settings is per user. If I came across a new website, I would have to log into 200+ accounts and make modifications each and every time. Not really a viable solution. In G Suite Admin control panel, under "Device management > Chrome > Apps & extensions > Users & browsers" the app has the option for "Policy for extensions" that accepts JSON. This program exports a JSON file, but it doesn't work when applied to the "Policy for extensions". If the exported JSON could be plugged into the "Policy for extensions" section, I could modify the program for all users across the organization in a matter of minutes. Please add this functionality and, I would suggest, the User-Agent I mentioned above, as it seems to solve a lot of issues that none of the default user agents fix.
javascript 指令 navigator.userAgent 無效
Most of the UAs are for browsers mostly not in wild for the past 3 years ... SO IT IS BODERLINE NOT USABLE ...
this extension no longer works on instagram~
В интаграме ничего не изменилось, подскажите что делать!!
Non funziona più su Instagram che, tra l'altro, era l'unico motivo per cui utilizzavo l'estensione... Strano perchè ho due pc e su uno va e sull'altro no. Cancellato cronologia e balle varie ma nulla. Continua a non funzionare.
J'ai téléchargé cette extension pour instagram et cela fut inutile.
Internet Explorer 11, please !!
I just want to know if I can fork it into a different extension, that or submit a PR of some kind? I've fixed the extension not being able to spoof JavaScript sites. I've still got to add a new option into the options page, but I don't think that's going to be very hard.
