I want to disable offline auto-completion for facebook.com, bbc.com and other ‘popular’ sites on android.
I found the lists of domains were added with this commit https://github.com/mozilla-mobile/firefox-android/commit/65fdbf4696a but I cannot find a suitable about:config option to disable this feature.
Here? https://support.mozilla.org/en-US/kb/add-or-remove-search-engine-firefox scroll to remove near the bottom
Firefox on desktop does not have this; also its not related to search engines, these lists of domains are embedded into firefox.
