Firstly, updating the browser lets you access all of the HTML scripts and make the newer browser compatible with a website full of graphics and text. Most website designers and web developers pay heed to browser compatibility, or to develop the site in a way, that it supports more than one version of a browser. Only an up-to-date version web browser enhances the browsing experience the best way possible.
It is easier to download and install the latest version of a browser. The root certificates get updated as well with browser installation and that helps avoid certain connection errors or SSL errors that pop due to poor browser compatibility. For instance, if you have come across such errors on Internet Explorer, Google Chrome, or even Mozilla Firefox, it is worth installing the latest version of the browser to negate it with embedded root certificates.
No more error loading a webpage, page not displayed or website component files not loading properly including latest HTML scripts, images, and other features that improve the functionality or the aesthetics of a website being visited. An out-of-date browser does not perform such basic surfing tasks with efficiency and speed just like newer version web browsers often tends to. While updating a browser is only a click away, why even hesitate? The browser updates often come up with bug fixes and security patches, among other things that make surfing the web stable and secure.
Think of a security patch released for a browser like Mozilla Firefox, which disallows hackers from taking control of the PC running on Windows 7 or Mac OSX. The fact that a latest version Mozilla Firefox could prevent ethical hacking or a new Google Chrome update could negate website redirects is reason enough to perform a browser update. You may also get accesses to new features that were not there in a previous version if the browser developer chooses to embed upgrades.
