updates

Hi Koy,

about:config changes are not recommended and even discouraged. There is no guarantee that any of the prefs will persist or keep its behavior.

However, if you share the actual issue(s) you experience, we may be able to help.

Glad to hear you're not having any issues. Not everyone's that lucky so these updates are shipping to fix stability and security issues every few days for those affected.

Notably, you're on unstable Beta version channel, as already noted in your previous question: support.mozilla.org/questions/1584565 — you chose that channel with more frequent updates deliberately for a reason.
