What Does Your User Agent Say About You?

Archive

A user agent is a computer program representing a person, for example, a browser in a Web context.

Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.

Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.

The user agent string can be accessed with JavaScript on the client side using the navigator.userAgent property.

A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

It's easy to search the millions of user agents we've got with the API. There is protection in place to stop the scraping of these user agent listings.

We've had to do this because otherwise we get constantly overrun by inconsiderate or malfunctioning bots which overload the system. As such, we're forced to block traffic from popular web hosting companies, VPNs and Proxies, we also rate limit requests and have some other checks too.

When we asked Nvidia if we could expect an official launch of in-browser game streaming outside of Chrome OS, we received the following statement: “We're focused on Chromebook. Unfortunately, that doesn't sound like official support is high on the company's priority list, but it also doesn't seem like there's any catch or known problem that would hinder you from enjoying your in-browser gaming session via the described method.

I haven’t found any indications of publishers actively blocking any of these browsers even on a small scale. I’ve found over 21 easily detectable characteristics which are unique to Brave, and it only took me half an hour to discover and test these.

I don’t believe there are any legitimate reason to fingerprint individual users. When they check their access logs, they’ll see that Brave has 0 users.

The previous mechanism detected a special property of the window object. Brave doesn’t care much to maintain compatibility with the Web Platform and standards.

One of the weirder things it does is to remove specific URL query parameters from all requests. To detect Brave : From the client, send a request to a specially crafted URL (below).

It is designed to collect user feedbacks and bugs about this add-on. Users can suggest improvements or feature requests through this form too.

There are 26 popular user agents to choose from! Read the privacy policy for this add-on. Please check the YouTube tutorial below to get an idea of how this add-on works in your browser. If you want to contribute to the development of this add-on, please fork it on GitHub, and push your changes to a named branch. Toolbar popup UI provides an easy interface to access all 26 user agents.

Clicking on any UA, will change your browsers user agent immediately. Second row is for desktop user agents which includes Google Chrome, Opera, Firefox, Safari, MS Internet Explorer and the new Edge browser by Microsoft.

The last row in the popup UI is dedicated for the control options including a button to change the UA to its default value. Moreover, some websites make look better in mobile devises while you are surfing in a desktop browser.

Therefore, being able to switch between different user agent on the fly could be a big advantage when you are online. The process for changing user -agents on-the-fly after the extension is installed in your browser is an extremely simple task.

In other words, user agent switcher can quickly switch between iOS, android, and other famous mobile devices. Whether you use Firefox, Opera, chrome or Safari, the User agent switcher will work with your existing setup.

Simply open the toolbar-popup and click on the desired user agent, selected UA is marked with green border. Windows Phone, which is a mobile OS from Microsoft for its windows-phone devices.

To see your browsers user agent, you can use many websites that offer this service for Free. But, if you do not want to completely remove this Add-on, you can simply open the toolbar popup, and click on the “Switch to Default” button in the bottom left corner.

This way, your browsers user agent will be switched to its default value and no actions or changes will be made by this Add-on. Once the UA is changed, click on the edit button in the bottom right corner in the popup.

When you see the edit window opened, make your desired changes and click on the OK button. Please note, before editing any user agent make sure the new value is a valid UA, otherwise the Add-on will not be able to change your browsers user agent and end up seeing errors in websites that you visit.

If you want the selected user agent to be active on a specific website only, please open the toolbar-panel UI and enter the website address in designated field (input area in the bottom middle section). In other words, if you do not modify the URL field, the UA will be applied to all websites and domains.

In order to change the UA, the Add-on works in two separate modes. The other mode is the navigator user agent, which is changed within the page before it is loaded.

Is this Add-on compatible will all versions of Firefox, Opera and Chrome Yes, it is fully compatible with all versions of modern browsers including, Firefox, Chrome and Opera.

Please note, you can edit/update any of these strings from the toolbar popup UI once you run the Add-on in your browsers. Please note: keep these reviews clean, and avoid the usage of derogatory or inappropriate language or terminology in references to individuals or groups based on race, national or ethnic origin, color, religion, age, gender, etc.

While all the above sounds great, over time the Sergeant has been misused by some web developers and occasionally even abused by the bigger tech companies, in positions of power. Vivaldi is frequently blocked, shown alternate (incorrect) versions of a website or spurious warnings are displayed, based solely on the Sergeant.

Sometimes it could arguably be considered a mistake, with the development team of a website naively assuming that only browsers they have personally tested be given access to their site, blocking anything that isn’t. Although it is a big hack job, it works surprisingly well in much the same way as providing someone else’s name can get you into an exclusive club.

We also often encounter websites that block the exact string “Vivaldi”, with no contact or warning to us. This is particularly problematic when the larger technology behemoths (some of whom we directly compete with in the browser space) do this.

When this happens and error messages are displayed, or intentionally invalid copies of the website are sent our way, users typically assume Vivaldi has an issue, and even sometimes struggle to comprehend that anyone would target us. This can be clearly seen by us in testing, by intentionally misspelling our name by one character in our Sergeant, e.g. “Vivaldi” or “Vivaldi”.

On Google.com if you present a Vivaldi user agent and arrive via a redirect, the search text box will be misaligned On Google Docs if you present a Vivaldi user agent you will receive a warning On Facebook’s WhatsApp web interface if you present a Vivaldi user agent, you cannot enter the site and are advised to switch to one of our competitors On Microsoft Teams (chat and collaboration website), presenting a Vivaldi user agent will stop you from being able to use the website On Netflix, presenting a Vivaldi user agent results in a suggestion to install Silver light to play videos… yes… really… Silver light! In all such cases, we have tried via various means to get someone in the respective companies to stop breaking these sites for our users.

Follow-up requests have been made both by us and our more technical fans multiple times since than, via various contact channels but to no avail. The problem with our current approach is that with the web being almost infinite, we can’t possibly discover all the websites who have blocks set against us.

For a handful of sites where we know the label Vivaldi (and our version number) is responsibly used, we will present our full Sergeant. There is a downside for us in doing this since Vivaldi will effectively disappear from third party rankings of browser popularity (we will be indistinguishable from Chrome) but that is a price we will happily pay to provide the best website compatibility for our users.

A fan of Linux (Slackware), uni cycling, simple solutions and a “slow” lifestyle. 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.

If you don’t see the console at the bottom, click the menu button in the top right corner of the Developer Tools pane–that’s the button just to the left of the “x”–and select “Show Console”. On the Network conditions tab, uncheck “Select automatically” next to User agent.

It only works while you have the Developer Tools pane open, and it only applies to the current tab. To create the preference, right-click on the about:config page, point to New, and select String.

You can find extensive lists of user agents on various websites, such as this one. This setting applies to every open tab and persists until you change it, even if you close and reopen Firefox.

To revert Firefox to the default user agent, right-click the “general.user agent.override” preference and select Reset. Microsoft Edge and Internet Explorer have user agent switchers in their developer tools, and they’re nearly identical.

To open them, click the settings menu and select “F12 Developer Tools” or just press F12 on your keyboard. The developer tools will open in a separate pane at the bottom of the window.
