certain buttons such as quote are missing from forum pages

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).

Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.

• Firefox > Preferences > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

A Safari and Firefox grab attached to show the difference

Thanks

Did you check that you aren't blocking background images because website colors are disabled like I posted above?
