Last but not least, there's also an improvement in Firefox's handling of multimedia content. According to tests, Quantum Compositor has reduced GPU driver-related crashes by 17%, which isn't a lot, but it's an improvement that adds to the many similar optimizations Mozilla has been adding to Firefox in recent releases.Ī change meant to improve user privacy was made to the Firefox Site Permissions system, which n ow features improved graphics that stand out more and are harder to ignore, looking more like the permissions systems used with Chrome and Android. Other changes in Firefox 53 include the addition of a new feature called "Quantum Compositor" for Windows users, meant to improve the stability of the Firefox graphics package. Their look and feel will remind some users of the Microsoft Edge interface, and they're a breath of fresh air compared to the same ol' Firefox UI we've been seeing for the past few years. Called "Compact Themes," these are the two themes that have been available for users of Firefox Developer Edition for the past years. Moving on to new features in v53, the biggest update in terms of visuals is the addition of two new browser themes. These security updates won't be delivered via the official Firefox Stable versions, but via Firefox 52 ESR release, so any XP and Vista users should migrate to that release.Īt this point, with no support from Microsoft or any of the major browser vendors, XP users have no choice but to update to a newer OS if they want to continue to be safe online.įurthermore, Mozilla has also stopped supporting 32-bit versions Mac OS X, and the browser maker is advising OS X users to switch to Firefox ESR 52 to continue receiving security updates.

Nonetheless, Firefox users on XP and Vista will receive security updates for six more months, which are also expected to stop after September 2017.

Firefox 53 is actually the first version with no XP and Vista support whatsoever. In reality, Firefox 52 was the last official version to receive new features on XP and Vista. XP & Vista Firefox users will get security updates for 6 months Mozilla was the last of the major browser vendors to support official versions for XP and Vista, operating systems that Microsoft officially retired. There are several new things in Firefox 53, but none more important than what's lacking, and that's support for Windows XP and Vista. Mozilla is expected to officially release Firefox 53 later today, but the Firefox 53 installer is already available on Mozilla's FTP servers, just in case some users can't wait to get their hands on the new release.
