Suddenly, two of my email accounts are showing blank messages on Firefox, but are fine on other browsers. I'm using Firefox 128.1 ESR. I recently updated Firefox from 128 ESR to 128.1 ESR. On one of them Ctrl-A highlights the main body of the email (GMX Mail) and then reloads itself and shows okay, but I'm not going to continue to use it like that. The other one, I can manually highlight the otherwise invisible text, but then it just goes away again, and this is my main email (Proton Mail), so it is unusable in Firefox. How do I remove the last ESR update? Do I have to switch browsers permanently or is this fixable? Thanks, AnneF
