Firefox 'darker videos on YouTube' bug after v113 update reported by some (workaround inside)

In the ever-expanding digital world, where web browsers serve as the portals to the online universe, Firefox emerges as a shining symbol of transparency, confidentiality, and personalized browsing.

One of the key new features in Firefox v113 is the enhanced picture-in-picture mode, which allows users to watch videos from the web’s most popular websites in a small window that stays on top of other apps.

However, amidst the positive changes, a disconcerting bug has emerged, affecting the viewing experience of YouTube users (1,2,3).

Firefox users have reported that videos on YouTube appear darker than usual, making it challenging to see details and enjoy content as intended.

Interestingly, users have noted that videos appear normal when played on other browsers or through native YouTube app. This suggests that the issue lies within the Firefox browser itself, rather than with YouTube.

This unexpected change in brightness levels can be both frustrating and jarring for those accustomed to a specific viewing experience.

Since updating to v113, videos on YouTube are way too dark. The difference between watching YouTube online, and downloading a video to watch with MPV, is very noticeable.

It is worth noting that this issue appeared again after Firefox’s v113 update, as users have indicated that they faces similar issue a long time back (1,2,3).

By setting the parameters given below, they have observed that videos return to their normal brightness levels.

1. Type in about:config on your Firefox address bar.
2. Then change the setting to these:
