[Bug] Firefox ESR tab crash (Signal 11) on video sites (YouTube/Netflix) caused by Passbolt extension

Hello Passbolt team. I am experiencing consistent tab crashes in Firefox when visiting websites containing video players (such as YouTube or Netflix). After extensive troubleshooting, I have isolated the issue to the Passbolt browser extension.

Environment:

  • OS: Debian 13

  • Browser: Firefox 140.14.0esr

  • Passbolt Extension Version: 5.15.0

  • Graphics: NVIDIA RTX 3060 Mobile (Proprietary drivers)

Steps to Reproduce:

  1. Enable the Passbolt extension in Firefox.

  2. Navigate to any YouTube video URL.

  3. The tab crashes immediately, displaying the “Gah. Your tab just crashed.” error page.

Error Logs:

Running Firefox from the terminal shows the following error when the crash occurs:

[Parent 15960, IPC I/O Parent] WARNING: process 16218 exited on signal 11: file ipc/chromium/src/chrome/common/process_watcher_posix_sigchld.cc:134

Troubleshooting Performed:

  • Disabled hardware acceleration (VA-API/Intel/NVIDIA drivers): The crash still occurred.

  • Created a completely new Firefox profile: No crashes.

  • Disabled all extensions in the main profile and re-enabled them one by one: The crash only happens when the Passbolt extension is enabled. Disabling Passbolt immediately stops the crashes on video sites.

Thank you for looking into this!
