If you ever wanted to make your web traffic seem like it was coming from a different browser–say, to trick a site that claims it’s incompatible with yours–you can. All popular browsers offer built-in user agent switchers, so you can change your user agent without installing any extensions. If the user agent you want to use isn’t shown here, select “Other” and you can provide a custom user agent. You can find extensive lists of user agents on various websites, such as this one. This option only applies to the current tab. Other open tabs and tabs you open in the future will use the “Default” user agent.

A user agent is a line of code that tells websites what type of browser and operating system you're using. This information helps the web server deliver content that's compatible with your browser.

You can change Firefox's user agent to trick outdated websites into thinking that you're using a different version of the browser. Web developers might do this to see how their websites will appear on different versions of a browser. Sometimes, add-ons and other installations can change your user agent without your knowledge. In any case, it's important to switch it back to the default user agent to display most websites correctly.

Every web browser uses user agent strings to have itself identified. The web servers request these strings to find out if it is Internet Explorer, Opera or Mozilla Firefox etc. The user agent strings are built inside the browser. But in Mozilla Firefox you can spoof the user agent strings. The result being that even if you are using Firefox, the web server would think you are using Internet Explorer or some other browser.

This is very helpful when some site insists on using Internet Explorer. I have seen some university web sites which refuse to work if you are using anything other than Microsoft Internet Explorer. You can spoof the user agent strings to have your way with such sites. This is how :

1. Start Firefox
2. Visit https://addons.mozilla.org/en-US/firefox/addon/59 in Firefox.
3. When Firefox asks your permission, click Install to install this addon. Then restart your Firefox browser.
4. When Firefox restarts, you would be able to access the User Agent Switcher from the Tools menu.

Please note that just by spoofing the User Agent strings, a browser will not render the sites like a spoofed web browser. If you are doing an important work like filling up an application form, or doing some financial transactions and a site tells you to use a specific web browser, you should do as directed.
