I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

I have boon using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and firefox behaves, until I stop it and restart again. Then I get the same message. I looked on line - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis jdpsmp@verizon.net
