Firefox - Number 9 is replaced by dashes on some websites (such as Whatsapp Web)
Number 9 appears as dashes on some websites as per example above. I also have a network media device and when I use the web interface it does the same.
I have tried the solutions provided in the previous 2 threads but no change. My system is Linux Mint 19.3. Iam asking here as the previous solution was archived and it advised me to start a new thread.
