Hello I've been experiencing an sporadic behavior on the Firefox Browser since version 140: some sites such Wikipedia or Discogs do render with strange characters from time to time (see attached example). It seems to be a tab related issue, because whenever this starts happening, it only happens in one tab. If I open the same page into a different tab or even if I duplicate the problematic tab, the new page will always render OK in the newly created tab. I have tried changing the font sizes, switching the page style to "no style" and back, resizing the screen, resizing the browser window, changing the default fonts and sizes in "Settings", deleting cookies and site-related data, etc. Nothing ever worked. Any idea? Many thanks in advance for your hints and comments. Cheers, Gonzalo
