Xda Browser display

I'm a newbie and am not sure where to ask this question. I'm accessing XDA forum via browser (Firefox) and have a question about the display. Threads where I participated are clearly marked. But threads I just read are just marked by being unbold. This is normally fine but in the color scheme XDA uses (orange-brown) the difference between bold and not bold is difficult to see. At least to my old eyes. Can I modify or select a different XDA webpage view that uses a different color where the difference is more clearly visible?

Or, is it just me?

(My nexus 5 was previously used by someone else. He used Tapatalk 2.4.15 . But it insists on using his login data - which he changed - and will not let me enter a new username and password. I don't like the latest version of Tapatalk.)
