We often leverage web browsers to access different web content. It’s inevitable that the browser plays a key role in determining the depth of user experience. Thanks to the advent of browsers, there has been an upward trend in the usage of apps, extensions, and plugins.

Since there has been quite an increase in the devices and brands, we are having a tough time determining the right browser to use. It’s common for users to get muddled when they want to find the right browser compatibility. This is why its popularity is soaring high. Hence everyone should know how to activate compatibility mode in browsers.

In this new blog, let’s learn what Chrome compatibility mode is, why you need to enable it, how to get it done, and how to easily fix Chrome compatibility mode bugs. We will also explore how LambdaTest is gearing high in this domain.

So, let’s get started!

What is Chrome Compatibility Mode?

With the incredible growth of online web browsers, the technological rise is inevitable. Hence, web designers and developers should ensure that the websites they create are compatible with the latest tech stacks.

Google Chrome has a feature where you can enable Chrome compatibility mode to experience the older versions of your current browser with fewer restrictions and more accessibility to more data available on the Internet. With Chrome compatibility mode, the user can take care of the aesthetic appeal of a website, like leveraging the previous Internet Explorer version.

When a website consists of “active mixed content” successfully loaded into an HTTP page, there will be a blockage from the browser to prevent exploitation. They have designed this feature to safeguard the website from losing sensitive page information. This will also ensure that the online browser testing is a success.

What are the other ways to troubleshoot the program?

Chrome has offered us abundant ways to troubleshoot the program. Many of them can be fixed within a few steps.

Solve Aw, Snap! Error

When you test on Chrome 84 browser online or any other version, it’s annoying when we want to load a page, and we get to see this Aw, Snap! Error. Try these methods to get rid of it:

  • Clear the entire chrome browser cache.
  • Update the latest version of Google Chrome.
  • Completely reset your Chrome settings.
  • Disable your VPN settings.
  • Consider re-installing Google Chrome.
  • Check quickly to know if it’s an ERR_NETWORK_CHANGED issue or otherwise.

UserAgent Detection

The code snippet may assume every browser as IE. The code fork may fail if the code snippet does so since many other browsers would show similar behavior. The best solution would be to try another browser version when you get a message that the browser is unsupported. Look for the “appleWebKit” string in your navigator to confirm that the browser leverages WebKit. You can learn more about it in our earlier blog on CSS with feature detection.

Use Browser-Specific CSS

When a few browser-specific CSS styling techniques wouldn’t be compatible with Chrome, you need to look for an alternate option. Though they may seem to be working fine, avoiding using them when you handle non-critical tasks is better.

  • Instead of using document.all as a part of JavaScript, leverage document.getElementById(). This feature would be an outdated Google Chrome addition with support for every modern browser.
  • Skip using CSS expressions compatible with only Opera to avoid rejection.

Get Error-less Plugin Logs

Different browsers would make use of different plugin types. For instance, Google Chrome uses only Netscape Plugin Application Programming Interface API (NPAPI). When you miss the plugins such as Windows Media Player movies or Flash videos on Internet Explorer or Google Chrome, ensure that the parameters in the < embed > and < object > tags are the same to prevent confusion.

When you make use of plug-ins where the support is only offered for Active-X version, it’s not going to work in many browsers such as Google Chrome without using the IE rendering engine. IE would also use the object tag for embedding a flash video. Then, it would load the file flash_ad.swf while ignoring the browser’s embed tags.

Accuracy in Page Encryption

If you don’t properly define the character encoding, it would surely affect the way various browsers interpret your message. Your page would surely appear distorted when you view it on Google Chrome. It would also display garbage characters.

To solve this, you must ensure that you correctly set the page content type. The characters you use to set the page’s content should be directly from the IANA list, with only encodings containing the desired text. Avoid conflicting values since Google Chrome gives preference to them. It’s also advisable to use UTF-8 when you face problems with legacy encoding. Don’t use Visual Hebrew encoding since it lacks logic to render text.

Breaks in Overflowing-in-Section

When a single line present in the layout of the site can get wrapped around different lines, it could cut off or overlap other elements. The issue is mainly faced when you lack pixel-perfect layouts for the browser versions. When there is a change in the website’s element and font sizes of the browser and OS version, it could lead to the text getting wrapped or cut off around different browsers.

To avoid these bottlenecks, you should avoid setting your website’s fixed pixel width the next time. You can instead use dynamically-sized elements. You must test your website in different OS and browsers to check for the maximum size.
