@Kresimir said it first:
only problems with fonts in firefox for me get solved by installing ttf-ms-fonts from AUR
Thanks @Alexander for posting this problem and @keybreak for posting the solution. I never realized font renditions looked so terrible in Firefox and a few other apps. Applied this fix on both my desktop and laptop. Night and day.
I’m glad it worked out for you!
I did the tweak on my Cinnamon DE and I think I see a change. I probably should have made a screenshot from before. But I think think the letters look better now.
I just did it on my Arch Cinnamon DE, seems to have worked.
Has this been remedied or is this still necessary. Anyone know?
Pudge
I haven’t done it on Arch/Xfce or EOS Plasma and it seems like its not needed, according to my eyes anyway lol.
