make incompatible add-ons outstanding in the list at about:addons

[grahamperrin]

The blue of the circle around the ℹ stands out more (contrasted against the white background) than the yellow of the triangle around the exclamation mark.

More generally:

• the compatible lines are superfluous, their presence does not make it easier to see, at a glance, what's compatible.

Better (mocked up):

It might be even better to apply a yellow highlight to the relevant text,

Not compatible with multiprocess.

– but (please) don't make it as LARGE, LOUD AND SHOUTY as the 'LEGACY' alerts that are integral to Firefox 55.

If not highlighted text, then maybe a different colour triangle, or a more contrasting border to the triangle, for the exclamation mark.

Thanks

I guess that attention to just a handful of lines, including https://github.com/mozilla/addon-compatibility-reporter/blob/2bb1975d538d4f0dbdf09a838d38818be3d664df/data/reporter.js#L64 and https://github.com/mozilla/addon-compatibility-reporter/blob/2bb1975d538d4f0dbdf09a838d38818be3d664df/data/reporter.js#L118 might be enough.

(For myself I tried, but failed, to install a hacked copy of the extension.)

This add-on will stop working with Firefox 57 and we don't plan to make any more changes to it.
