User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

I rotated my laptop screen upside down (I am using Lenovo Flex), so that the subpixels order on the screen changed from RGB to BGR. I changed ClearType settings in Windows to "reverse subpixels order", restarted Windows. Now in Windows interface the fonts are rendered properly.

Actual results:

In Thunderbird fonts throughout the whole application (on pages, dialogs, menu items) are now blurry because Thunderbird still continue rendering fonts in the regular subpixels mode.

The same bug takes place for Firefox, bug 1556302.

Expected results:

I expect Thunderbird should recognize both screen rotations and ClearType settings change, and render properly even without restarting Windows or Thunderbird.
