Firefox 64.0.2 fixes video stuttering on YouTube
Mozilla released Firefox 64.0.2 to the stable channel on January 9, 2019. The new version is a bug fix release that addresses several issues of the previous version of Firefox including a video stuttering issue on YouTube and a crash fix on Mac OS X devices running Firefox.
Mozilla released Firefox 64.0. in December, and Firefox 64.0.1 for Android exclusively (Firefox 64.0 was not released for Android).
The new version is already picked up by Firefox's automatic updating functionality; users can verify the version by selecting Menu > Help > About Firefox from the menu. An option to run a manual update check may be provided as well depending on how updating settings are configured.
Firefox 64.0.2 can be downloaded from Mozilla directly as well; either to install the browser over an existing installation or install it as a new program on the device.
Firefox users noticed micro-stutters on YouTube when playing videos after the upgrade to Firefox 64 even with the video quality set to Auto and on relatively powerful machines where this should not happen. The issue affected Firefox on all supported operating systems (desktop) but not other browsers that users ran on their devices.
Mozilla analyzed andÂ fixed the issue in December, when the issue was reported to the organization on Bugzilla. The analysis found that about 10% of frames were dropped on affected versions of Firefox. The fix was rolled out to Nightly versions of Firefox first to verify it.
Firefox users who ran into video playback issues on YouTube should upgrade to the new version to fix the issue.
Firefox 64.0.2 features four additional fixes for issues. One issue fixes a browser crash on Mac OS X devices that started in Firefox 63.0.3. Mac Os X users reported that Firefox would crash, often during payment processing operations.Â The issue should be fixed in Firefox 64.0.2.
The three remaining fixes are:
- Japanese language version updates.
- Column sizes are properly restored in the Developer Tools Inspector tool.
- Â Lightweight theme updates fixes.
Interested users can check out the full changelog on the Mozilla website.
Firefox 64.0.2 for Android fixes a crash that occurs when Firefox is put in the background, and another crash when Web Speech is used.
