Hi everyone,

I've installed Debian 12 with Firefox 102.12.0esr (64-bit) from scratch instead of Debian 11. Just after it I noticed that all add-ons I used for a long time do not work anymore.

When I go to Menu > Add-ons and themes, I see all add-ons enabled. However, all of them do not work, and they even do not display their icons on the Firefox toolbar as they did before.

A couple of examples of add-ons that do not work: - Enhancer for YouTube - ImTranslator: Translator, Dictionary, TTS

I run Firefox via Firejail sandbox (like I did for years without any problems). All add-ons and settings came to my new system via Firefox sync. I tried to run Firefox directly (without Firejail) and nothing changed, add-ons still do not work. Also, I logged out of my Firefox sync account and reinstalled add-ons on Firefox running directly (without Firejail) and it did not help.

Appreciate your help - how can I enable add-ons in Firefox?

Hi there. I solved the issue. The root cause was setting "Always use private browsing mode". I disabled it and add-ons started working. Alternatively, I could enable add-ons to run in the private browsing mode.
