Here is a link to the thread:
I see no problems on a Windows 11 computer in Chrome, using Discourse-Classic Theme.
To check theme:
- Click on your Avatar next to the Menu. (Upper Right Corner)
- Select Preferences (The last symbol on the right)
- Select Preferences again (The gear symbol)
- Click on Interface. (Should be the last choice.)
It is most likely a Firefox issue handling some stray unusual piece of code, possibly in one of the less used themes.
