Well I tried to make a test page to find a good value for the font size, but it proved impossible. I realised after some looking around that one of the reasons that eMatrix displays such a small font size is that I have messed around with Pale Moon preferences to change the looks of the browser. The short story is I need those changes, but they also make it hard to judge the font size needed because on an html page a font size of 96px looks plenty big, but in the eMatrix menu it is way too small.I can increase the upper limit but I don't know how much is enough to make it readable. While I do have a slight hearing impairment I can still see relatively well and I might underestimate what "big" is. If you (or someone you ask for help) can provide an approximate size I can use it. Maybe create a web page (even a local HTML file is fine) and test various numbers with CSS.
I am wondering now if it would even be possible to make it workable for my needs. I would guess that the needed size would be considerably larger than what it is now, maybe upwards of 400px or even larger.
i will try to attach a screenshot to show what it looks like for me. You'll have to excuse the apparent mess of my browser, with my disability I am not concerned with it looking pretty, it just needs to be functional for my needs. But you should be able to see the eMatrix menu in the topright corner and how there's no colour and the font size is smaller than the rest of the PM menu texts.Can you show me a picture of what you see when you have high contrast mode activated? Even though I could activate it myself and see, I'd rather get pointers from the person actually using it and get a more accurate picture of the situation.
Adding a dedicated "high contrast" setting should be fairly easy, but since the extension can't pick up whether the system is using a certain mode/theme I'd need to explicitly select colors, sizes and decorations for each element.
Thank you for the effort.
