Firefox Community Forum

On some websites, the ligatures for ff, fi, fl, and others are scrambling with other font rendering behaviors.

I can most clearly test this on the mobile version of wikipedia (normal wikipedia doesn't have this problem since it uses a different font), but there are other sites experiencing the same issues. The issues are as follows:

1. Typing "fl" renders as "ft" instead.
2. Typing "fi" renders as "ff."
3. Typing "ffl" attaches an accent to the preceding character.
4. Typing "ffi" renders as an uncommon "st" ligature.

I have attached images showing each of these rendering issues. Note that the titles are not bugged, because they're being rendered in a Sans Serif font.

I am only getting this issue on Firefox. Other browsers like librewolf do not have this problem. Still, I tried reinstalling Roboto, and it did not solve the issue. I am running Arch Linux on the X window system.

See attached screenshot. It just randomly happens from time to time, and I can't figure out what's causing it. I've used both Chrome and Firefox with the same results. Help!

I had Firefox installed and working perfectly fine , but I had to factory rest my MSI laptop (windows 11 home) because I had suspect suspicious files I needed to get rid of, after the new install of Firefox each time I try to sign into a google account I would be able to type 2/3 letters and then Firefox crashes and closes down , I had uninstall and downloaded a fresh install from the microsoft store
