This crash was from Oct 2025 and I submitted it this morning - did not know about this until now. bp-ec86ae4b-b452-40e4-8956-d5e730260427 There was no crash for my incident. I attached what I received when I try to upload a file to Nordlocker. https://cloud.nordlocker.com

This is occuring on two different laptops I own. I uploaded a file Saturday morning on laptop at home, then the Firefox update occurred and receive the tab crash. Turned on work laptop this morning, Firefox update occurred and received the tab crash. Had no problems uploading files prior to updates on either laptop.
