I’m rather insistent about scaling zoom being set by default 120% of my copy of Firefox. I achieve this with the NoSquint plugin add-on. Of late I’d been noticing that Firefox page scrolling was really really really bad.

Turns out this is caused by scaling zoom — turn the default page zoom to 100% and performance is really good, with scrolling being smooth and uniform.

Also, I today discovered that I’ve been right to avoid using the word performant — performant is not a word! Seems this is quite endemic to the technology industry as I’ve seen this word being used in everything from white papers to published books…
