Mozilla Firefox Crashing and Tabs Becoming Non-Responsive After Session Restore

WEBBAR — Thu, 19 Feb 2026 19:26:32 GMT

I am experiencing recurring stability issues with Mozilla Firefox. My normal workflow involves running multiple browser windows simultaneously, each containing numerous tabs. Historically this configuration has been stable, but recently Firefox has begun crashing unexpectedly. Issue Description: Firefox crashes without warning during normal usage. Upon restart, Firefox successfully restores the previous session. All windows and tabs appear visually present with content loaded. However, some tabs become non-responsive: Tabs cannot be selected or activated. Clicking on certain tabs does not bring them into focus. The content remains visible, but interaction with those tabs is not possible.
