I am on the beta channel of Firefox and had no issues in the past, but I now have to report one which has “already been reported”.
The bug and its cause are known and the fix is known as well.
It is the following bug:
Now why am I talking about it?
Because like the person who reported that bug, this bug occurs on my system, I do have the EmojiOne Color Standard font installed and I also have no clue where the EmojiOne Color Standard font comes from.
I do not have weird or experimental software installed, other than the FF Beta. The font was installed in March 2021 and is therefore newer than my OS installation. I have not knowingly installed that font.
When I encounter a problem, I ask Google for the solution, but Google did not find the answer - a manual search on bugzilla for “emoji flag” gave me the answer.
As I did not intentionally install this font, it must have been installed by a program, and I suspect it was a common one. The closest things which were installed around that time were “The Outer Worlds” (5 days prior), “AMD Ryzen Master”, “AMD Chipset Software”, “Realtek Audio Driver” and “Realtek Ethernet Controller Driver” (all 1 day later).
This means that if the FF 97.0b3 gets to release, the “bug” will occur on many systems, as I suspect the drivers to be at fault for installing the font.
I did not post under the bug, because this is basically an iteration of “I have this problem, too”.
Instead, I just want to make the developers aware of this issue.
