Thanks for the reply. This thread may give us some clues: https://bugzilla.mozilla.org/show_bug.cgi?id=1941820

Some fonts may require additional configuration to display properly, so usually manual installation should be avoided.

Please run (and post the result here) fc-match sans and fc-match serif to check fontconfig picks wrong italic font. If that’s the case, try to remove the TTF files you’ve installed via the font manager you’re using, then install the fonts via the package manager - it should configures fonts properly.

The SCHEMA:PATH part seems slightly wrong (singular vs. plural). Try:

schema=org.gnome.settings-daemon.plugins.media-keys.custom-keybinding
path=/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/

gsettings get "${schema}:${path}" binding
gsettings get "${schema}:${path}" command
gsettings get "${schema}:${path}" name

If anyone has other suggestions to mitigate this

Firefox has “permissions.default.image” (link) option that disables image loading, but this Wikipage is very old so I’m not sure whether it works properly in current FIrefox.

I’d write a bookmarklet for that case:

javascript:
{
const name = 'ABC';
const d = new Date();
const year = d.getFullYear();
const month = d.getMonth();
const date = d.getDate();
document.activeElement.value = `${year}/${month}/${date} ${name}`;
void 0;
}

This bookmarklet inserts the desired text into the currently focused text box. Tested on Lemmy Web UI.
