@Anonymous You can't do that on Firefox for Android, which is probably what @MC_Man_CZ is talking about when mentioning "mobile Firefox". The reference you give is only correct for versions of Firefox that give access to about:config, and Firefox for Android doesn't do that. I strongly support this feature request, as automated updates might be a security liability as recently illustrated by the "ShadyPanda" scam https://thehackernews.com/2025/12/shadypanda-turns-popular-browser.html.
