Yes! It’s OpenDyslexic that I’m using!
Great font
I tried to change it back to normal fonts but it still looks blue after the change.
There are some color options in the settings, I clicked those to “never” use. It was on highlighted setting.
I also tried Always just for test, that changed all kinds of colors to black and white mostly.
It’s on “never” now.
But did not change anything.
I saw one color there, “visited links” that looks pretty similar to the text color.
But changing it did not change the site so probably not it.
I could not find any other setting about color.
I tested using opera Browser, it works fine there I see how it should normally look so it’s definitely my FireFox that is doing something naughty!
I tried to use opendyslexic with opera but could not get it to actually work even though changing the fontsettings, so don’t know if it could be the font itself.
I really like this Vincent one now so I will continue to use it.
If I ever fiddle with the settings more and find the issue I will post about it here so anyone else who might get the same can read solution!
I use some other plugins in FF.
Like noscript, allowing level1techs.com
Adblocker plus, canvas fingerprint defender among a few more, they could probably mess things up too!
