User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

Open Whatsapp Web and insert an accented character such as é, è or à. This only happens if no other character is inserted. If, for example, a space character is inserted before an accented character, it works normally. This problem also occurs in Reddit's markdown editor.

I'm on Arch Linux and Wayland. Firefox was installed via Flatpak.

Actual results:

Accent is not inserted and the character get's deleted.

Expected results:

The accented character should be inserted correctly.

It works fine on macOS and Nightly for me, so it might be a Linux or flatpak specific issue.

Can you test latest nightly without flatpak? Can you also test X11 mode? (i.e. run with MOZ_ENABLE_WAYLAND=0).

Tested both scenarios. Bug still persists.

Tested with CS keyboard layout and I don't see the bug on Whatsup, I can input á or í as first input letter without any issue. Tested on Fedora 41/Gnome. Please attach your about:support page. Also have you tested Nightly with clean profile?

Yes, tested Nightly with clean profile. I've had this issue for years on almost every instance of Firefox I've used.
I'm using the ABNT2 keyboard layout.

Can you try Mutter as nested compositor?

Same problem. Tested both X11 and Wayland Firefox backends.

Hello! I have managed to reproduce the issue with firefox 137.0b2 flatpak on Ubuntu 22.04.

I will mark this issue as NEW and update the flags in order to get our developers involved and provide a solution in the next releases.

Have a nice day!
