New Update Issue - Google Sheets Cells Black

Hi, Sorry to hear that. Here are some standard troubleshooting steps that may resolve the issue: # Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield [[Image:Fx89ShieldIcon]] icon at the left of the address bar. #* If ETP is enabled, try disabling it. # If the problem is not fixed, try [[How to clear the Firefox cache | clearing Firefox cache]]. # If it does not help, also try [[Clear cookies and site data in Firefox | clearing cookies and data]] for the website you experience troubles with (''warning: you will be logged out on this website''). # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode | running Firefox in Troubleshoot Mode]]. If the problem doesn't persist, please follow the steps from [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems | this article]] to troubleshoot further. Does it help? Looking forward to your update!

Things that did not help: * Disabling ETP * Clearing cache * Clearing cookies and data What did help: * Disabling hardware acceleration, as suggested by https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems I am using an NVidia GeForce RTX 5070 Ti graphics card with Windows 11 Pro, version 10.0.26200.
