I noticed that since Firefox 39 or 40, text inputs on some of my sites are displayed with a different font. In the CSS, they used to have the font inherited from the body, and I can correct it by setting a font for text inputs explicitly.
The changed font does not look good on my sites, as it seems to be one of those modern fonts, while I have content text in Trebuchet or Georgia.
I didn't find anything about this in the Firefox release notes. I tried turning off some add-ons, but that didn't make any difference. I tried changing the default font in the Options, and that didn't make any difference either. (I only checked on my own desktop computer, so it could be specific to it.)
Anyone else noticed this?
Anyone any idea what happened?
