The Bugbug bot thinks this bug should belong to the 'Firefox::Theme' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

This pref was added in bug 1339144. Not sure why it would affect webextension themes.

Hello,
I reproduced the issue on the latest Nightly (127.0a1/20240424093459), Beta (126.0b5/20240424091756) and Release (125.0.2/20240419144423) under Windows 10 x64.
Once Firefox is restarted, following the steps to reproduce from Comment 0, the browser defaults to the built-in Light theme (in my case) and the installed theme is no longer used, even though it’s still installed and enabled.
