Dear Firefox Support Team, I am experiencing an issue with Firefox where it unexpectedly closes without any warning or generating a crash dialogue. This issue occurs when switching between any tabs, not exclusively ones with active media content such as YouTube, as previously suspected. This problem has persisted across multiple instances, without a discernible pattern or specific tab content causing the issue. **Firefox Version:** 124.0.2 **Operating System:** Ubuntu 23.10, Linux 6.5.0-27-generic **Extensions/Themes:** [Provide a list of enabled extensions, or note if the issue persists in Safe Mode] **Recent Changes:** [Mention any recent system or Firefox updates] **Graphics Card:** NVIDIA GeForce RTX 3070 Ti, Driver Version 535.161.07 **Steps to Reproduce:** 1. Open Firefox with multiple tabs. 2. Switch between various tabs. 3. Observe that Firefox occasionally closes unexpectedly without any crash report dialogue. **Attempted Solutions:** - Checked `about:crashes` with no submitted crash reports found. - Monitored for errors using the Browser Console but found nothing consistently leading to the issue. - Attempted running Firefox in Safe Mode to rule out extension-related issues. - Disabled hardware acceleration to see if it impacts the occurrence, with no change. **Relevant Logs and IDs:** - **Crash IDs:** N/A as no crash reports have been generated. - **Console Errors:** No specific errors noted that correlate directly with the issue. - **about:support Data(sanitised):**Name: Firefox Version: 124.0.2 Build ID: 20240401114208 Distribution ID: mozilla-deb Update Channel: release User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0 OS: Linux 6.5.0-27-generic OS Theme: Generic Application Binary: /usr/lib/firefox/firefox-bin Profile Directory: [Generic Profile Directory] Build Configuration: about:buildconfig Memory Use: about:memory Performance: about:processes Registered Service Workers: about:serviceworkers Multiprocess Windows: 1/1 Fission Windows: 1/1 Enabled by default Remote Processes: 14 Enterprise Policies: Inactive Google Location Service Key: Found Google Safebrowsing Key: Found Mozilla Location Service Key: Found Safe Mode: false Memory Size (RAM): 15.4 GB Disk Space Available: 1,468 GB Profiles: about:profiles All Crash Reports: [No specific report ID] Firefox Features - Firefox Screenshots: 39.0.1 - Form Autofill: 1.0.1 - Picture-In-Picture: 1.0.0 - Web Compatibility Interventions: 123.1.0 - WebCompat Reporter: 2.0.0 Add-ons [General categories without specific IDs] - Extensions: [List of extension types and general function, e.g., "Password Manager", "Dark Mode", without specific names or versions] - Themes: [Generic theme information] Graphics - Features: [General graphics capabilities] - WebGL 1 & 2 Driver Information: [Generic GPU information, e.g., "NVIDIA GeForce Series", without specific model or driver version] Remote Experiments: [Generalized experiment status] Accessibility: [General state, e.g., "Activated: false"] Library Versions - NSPR: 4.35 - NSS: 3.98 - NSSSMIME: 3.98 - NSSSSL: 3.98 - NSSUTIL: 3.98 Sandbox: [General sandboxing status] Startup Cache - Disk Cache Path: [Generic Path] - Ignore Disk Cache: false - Found Disk Cache on Init: true - Wrote to Disk Cache: false Internationalization & Localization: [General locale settings] Remote Debugging (Chromium Protocol): [General status] Printing: [General troubleshooting status] This problem significantly disrupts my browsing experience, and I have not found a consistent workaround.
