Also, color sensitivity may decrease with age. My maternal grandmother was, by the time she died, was only able to perceive highly saturated colors--everything else was either muddy brown or grey. I've also noticed that my mother, who is an artist now in her 60s, is losing the ability to distinguish subtle shades of various colors. As for color-blindness, my father was red-green colorblind, but while its effects was barely noticeable when he was in his 20s-30s, by the time he was in his 70s it was becoming a serious problem.

I get my eyes tested annually.

Not a clue. Until now, I was unaware that anyone else experienced it. Even my opthamologist was unaware of the condition--I had to fight to get non-tinted lenses a few years back because the tint screwed up my color perception when I was trying to match colors on the job.

In Ubuntu studio (xfce) I got the full horror. Nothing makes your day like reverting all the changes I had made since 26 to keep things the way I like them. I still have a few features that don't work the way they used to.

As soon as I upgrade to the latest LTS, I'll try installing Palemoon For Linux.

I hear yah. I just switched all the public computers in the library I run over to Pale Moon, after hearing yet another patron complain that "Firefox is broken!" A large proportion of the users here laboriously learned to use a computer and rely on careful repetition of the steps they memorized to access email or other simple tasks. Suddenly, the back button is in the wrong place, the tabs are on top, the progress bar is gone and so is their weather! They can't cope with the changes, and aren't savvy enough to be able to figure them out on their own.

So, after years of evangelizing Firefox, I find myself saying, "Just click on that little moon there; and they click; AND IT JUST WORKS LIKE FIREFOX.

Honestly, dev-folks--Unity, Australis, Gimp2.8 (File>>Save!!), etc.--don't you want us to spread the gospel of F/LOSS? Why do you have against average users? --or solid, functional user interfaces THAT ANYONE CAN USE?

Sorry. I guess I'm getting tired of being shot in the foot by my own side.

So, are they saying that if a car is dusty or has too many rust spots, that it won't be recognized as a car? ...or that you could escape a pursuing driverless cop car with flying chaff?

Somehow, I can't imagine that we would risk ourselves in a car without robust and redundant identification systems.
