There's great news!
I have tested this bug on Windows and Linux systems and this problem is no longer reproduced.
I opened each page from the list on the about:about page, reloaded the browser, moved each discarded about:* tab with the addon to a new window, and no error was noticed.

Tested on:

• Windows 11, Firefox Stable 117.0 (x64)
• Windows 11, Firefox Stable 137.0.1 (x64)
• Linux Mint, Firefox Stable 117.0 (x64)
• Linux Mint, Firefox Stable 137.0.1 (x64)

This ticket may be closed.

Great job! Thanks!
