Firefox Desktop (x64) worked normally until the version 135 update was installed. Now tabs (even a single tab) crash after startup unless Firefox is run in troubleshooting mode or Windows 8 compatibility mode. OS is Windows 10 Pro (x64) 22H2 on ThinkPad E495 (AMD Ryzen 5 3500U) Things that haven't resolved the problem: - Remove extensions and themes - Refresh Firefox - Reinstall Firefox - Updating Visual C++ 2015-2022 with Redistributable (x64) version 14.42.34438 - Updating Firefox to version 135.0.1 and subsequently to version 136.0, however updater only works in Windows 8 compatibility mode - Full system scan for malware (none found) Note: Extensions NoScript and Cookie AutoDelete work normally with Firefox running in Windows 8 compatibility mode.

Update to from version 136.0 to 136.0.2 never completed with Firefox running in Windows 8 compatibility mode. Turning off Windows 8 compatibility mode allowed update on restart to complete; however, the open tab immediately crashes after Firefox restarts. Like previous versions, Firefox 136.0.2 works in trouble shooting or Windows 8 compatibility mode.

Try testing in Windows Sandbox (VM) to see if you have the same issue. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/ Are you running any security software besides MS Defender? Have checked for system updates from Lenovo? Another tool I use for windows is Intel updates.
