Thunderbird 154 PDF preview prints blank pages

Suddenly since Friday 21.08.2026 morning every single person in our company started to call the IT department that their Thunderbird client is printing out blank pages (white pages) instead of attachments from emails. '''What is happening''' -> Employee gets email with PDF attachment -> clicks to open it in thunderbird print preview -> prints -> blank page comes out. '''What works''' -> Downloading the PDF and printing it. Opening the PDF in any other browser than Thunderbird and printing it. No settings or updates were changed and it's a big issue affecting multiple computers. '''What I tried doing''' -> Trying different printer (No fix), Resetting print settings in thunderbird (No fix). Trying other PDF attachments from older emails (No fix). Looking at print settings in windows (Which I didn't change since it only doesnt work in Thunderbird). Problem is that on thunderbird in my office, This doesn't happen. We have the same versions and settings. I tried opening the error console while opening the PDF and on computers where it doesnt work it shows me an error with along the lines of "This document is open in compability mode due to **** header <doctype html>" Something like that but i would have to check again. I don't get this error on my personal PC.
