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".

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. 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”. Sadly a host of site-specific workarounds (let’s not call them “fixes”) have to be baked into the browser permanently.

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. Because some internet websites unfairly block browsers from accessing their services, starting with Vivaldi 2.10, released today, the Vivaldi browser plans to disguise itself as Chrome to allow users to access websites that unfairly block them.

A UA string is a piece of text that browsers send to websites when they initiate a connection. For decades, websites have used UA agent strings to fine-tune performance and features or block outdated browsers.

However, many website owners these days use UA strings to block users from accessing their sites. Some do it because they're not willing to deal with browser-specific bugs, some do it because of pettiness, while big tech companies like Google and Microsoft have done it (and continue to do it) to sabotage competitors on the browser market.

The browser is not an outdated piece of junk that website owners need to block from their sites. Vivaldi is a modern browser built on Chromium, which is the same code that runs underneath Chrome.

Furthermore, when a website blocks Vivaldi, they also show messages telling users to upgrade their browsers. Sadly, needing to hide themselves as Chrome in order to gain access to various websites isn't a desperation move specific to Vivaldi alone.

Vivaldi Technologies chief executive Jon on Tetchier. SuppliedNorway-based Vivaldi Technologies, developer of the browser of the same name, says it has issued an update to change the browser's useragentstring to Chrome in order that it would work on all websites. “ Vivaldi users regularly encounter messages that they have to upgrade their browsers or the site will not work,” the statement said.

This coupled with the new capabilities 5G brings opens up huge opportunities for both network operators and enterprise organizations.

I'd like to introduce you to Threads, a more compact view for your Pocket notes, which happens to be a perfect fit for Vivaldi's side panels! For those not familiar with it, Pocket allows you to save web pages to read them later on the device of your choice.

Is there a way to have the left panel autohide and reappear when the cursor reaches the edge of the screen? Because some internet websites unfairly block browsers from accessing their services, starting with Vivaldi 2.10, released today, the Vivaldi browser plans to disguise itself as Chrome to allow users to access websites that unfairly block them.

That is why with today’s update, we’ve drawn a line in the sand so that you can browse more websites without a glitch.” Sadly, needing to hide themselves as Chrome in order to gain access to various websites isn’t a desperation move specific to Vivaldi alone.

Changing the useragentstring can be useful in certain scenarios when some website's functionality is locked down to the specific platform and you need to bypass the restriction. This allows developers to differentiate various device classes like tablets, phones, Desktop PCs and laptops, and more.

The useragentstring can provide web servers some details about the user's operating system, and the browser version. Google Chrome is the most popular web browser which exists for all major platforms like Windows, Android and Linux.

Alternatively, you can enter a custom user agent value using the text box below the list. The list includes various versions of Internet Explorer, Edge, Opera, Safari, Firefox, and Chrome.

Tip: If you are switching the user agent in Google Chrome frequently, you can save a lot of time and use the following extension: On this blog, Sergey is writing about everything connected to Microsoft, Windows and popular software.

For smooth running of Vivaldi on Raspberry Pi, we recommend to increase swap space. Making this change may diminish the life of your SD card.

If you are using Raspbian on a Raspberry Pi 3 and hear a when listening to music or watching videos, issue the follow command in a “Terminal” and then restart the Raspberry Pi: The latest version also gives users a novel option to match and even schedule their browser themes with the operating system of their devices.

Vivaldi is blocked for many reasons, and often by competitors, rivals and tech companies in a position of power. Vivaldi's users regularly encounter messages that they have to upgrade their browsers or the site will not work.

Although Vivaldi has made workarounds for a few of these issues, this is happening on too many sites and some are hard to fix. From this update onwards, users will be able to browse smoothly all those websites that claim to be incompatible with Vivaldi.
