Unable to open settings immediately after starting in Troubleshoot Mode

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.

That is strange. It's difficult to think of what might be different in loading that page.

What led you to go into Troubleshoot Mode in the first place?

I came across this issue by accident while investigating a different problem in a Firefox-based browser.

I thought it was specific to that browser, but I tried it in Firefox as well and the same issue occurred.

Helpful?
