The really long story: They added a bunch of stuff in that version and it's the last LTS before they removed a bunch of other stuff and a lot of companies are just too lazy to update their 10 year old crappy software.
However I'm not sure how trustworty their own statistic is.
On the other hand Mozilla's PoV:
neutral - JPEG-XL includes features and performance that might differentiate it from other formats, but the benefits it provides are not significant enough on their own to justify the cost of adding another C++ image decoder to browsers. A memory-safe decoder would reduce these costs considerably, and we are open to shipping one that meets our requirements.
Two weeks after 19-year-old Edward Coristine was viciously assaulted during a carjacking in Washington D.C., the White House says it would consider giving the administration official a Presidential Medal of Freedom for his bravery.
A 15-year-old girl and 15-year-old boy were subsequently arrested and remain in juvenile jail as the investigation continues.
Nice plot twist by the writers 10/10.
Excited for the next episodes of the series.
