User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20171019140425 Steps to reproduce: On a 4K laptop, start Firefox while an external full HD (low DPI) screen is connected and the internal screen disable. Open about:support. Disconnect the external screen, reenabling the internal one. Actual results: The about:support page font used in the table is now unreadably small. The part above the table is fine. Looks like the table font was not adapted when the DPI scaling changed. Expected results: The entire page should have adapted properly to the new DPI scaling, like most of the browser does.

I noticed similar issues on the about:addons page, this time going from high-DPI to low-DPI. The result is an addons page with huge font.
Similar behavior is showing in some add-ons, e.g. https://github.com/piroor/treestyletab/issues/1484
