Then, as the years crept ever forward, I began to realize this isn't a blast from the past...it's not like a discussion about the blink tag. It's a real thing that people still actually give a shit about 14 years later! My whole perspective on the thread changed.
I'm just gonna say that I have never once, in my entire 20+ years of building things on the web, wanted to change the color of the browser scroll bar. Until I read this thread I wouldn't have even realized someone would want to change the scroll bar. It seems like such an odd thing to do, and I'm imagining it looking silly, like something out of a 2001 page design (but maybe it doesn't look silly when done well).
But, I'm not a designer. Maybe I just don't get it. Either way, I use Firefox, and I do not care whether the scroll bar color can be changed.
Edit: I don't mean to insult folks who do think this is a useful feature. I'm really just expressing my genuine surprise at the entire tone of the linked thread. I don't oppose inclusion of this feature, and lots of people have mentioned valid reasons why they want it. I will likely never truly understand it, or share that desire, but I'm certainly not gonna get scrappy about it. And, I probably wouldn't even notice, if it did become available in Firefox tomorrow.
