1016556 - (fx-high-contrast) [meta] Firefox High-Contrast mode bugs

Status: REOPENED

(Firefox :: Theme, defect, P2)

Description

[Justin Dolske [:Dolske]]

Windows has a "High-Contrast" mode that's useful for visually-impared users (A11Y). Unfortunately, Firefox often doesn't look very good in this mode. Sometimes we're outright broken -- lower contrast than normal mode! -- in other case we simply don't look visually refined.

Firefox has historically considered A11Y a very important use case, so we should do better in High-Contrast mode.

Random notes I had jotted down:

Bug 963950 has a couple Australis-specific tidbits, but never really grew into a full-fledged metabug as our ship criteria for Australis was basically just to not make things worse than they already were.

Bug 343205 is a more comprehensive bug, but it's ancient and I don't know how much of it applies any more.

I'd like to see this bug cover a few main thrusts:

* Find and fix obvious visual problems with our theme. Straight-up bugs where contrast is obviously wonky.
* Theme refinement. High-contrast mode should not only have high contrast, but should look _good_.
* Checking in with our A11Y friends to see what else should be considered for inclusion under this umbrella.

And that's everything from my notes.

I'm making this a meta bug so we can track this as part of bug 1270272.

Hi! Going forward bugs here should be tested against a few different HCM configurations -- we have more than just windows support.

1. Windows HCM (Settings > Ease of Access > High Contrast Mode)
2. MacOS HCM (System Preferences > Accessibility > Display > Increase Contrast) Note: you may also need to adjust about:preferences (Language & Appearance > Colors > (menulist) Only with High Contrast Themes)
3. Linux HCM (Accessibility menu > High contrast)
4. Firefox HCM (Language & Appearance > Colors > (menulist) Always) Note: for this confiugration, you should not have any OS-level contrast preference enabled.
