You need to disable e10s in your options:

Bug is not related to 910022 because coloring is working with v48.
Bug was introduced with v49. I've attached a screenshot.

I missed your e10s hint, sorry. e10s was released for v49 and enabled by default? Is there a near planning to fix the open bug which was reported 2013? We have some websites, which using this basic coloring to hint users for availability on specific options.

Enabled only for a small group of users. You can type about:support and check the line "Multiprocess Windows". When add-ons are not compatible with e10s, multiprocess is disabled.
