I think you will have to use a method other than Mozilla to sign in to connect. I can use google and one other which I forget. Once you are signed in, you may be able to change your connected email account.

An user script of general application is one which changes the background colour of some sites. Also, for facebook only, FBPurity. _https://greasyfork.org/en/scripts/979-nobrighter_ _https://www.fbpurity.com/_

I use bookmarklets also to change background colour. Two are based on a script posted on reddit, two others from _https://www.squarefree.com/bookmarklets/_.

I'm not seeing any such posts on fedia.

After the first 'private' session ended, the mod replied to a post to the effect that someone had his phone and had made the sub private. This episode has lasted longer. The first was apparently 8 hours, this is now in its 3rd day.

Evidently, adding a tag to a bookmark enables that section. In my case it's already there.

Thanks for your help. My idea was misconceived. If the 'image' is hidden, there is nowhere to insert 'checkmarks'.

I amended the code. I am printing it here to be sure. The colour of the checkboxes has not changed. Back to the drawing board. I will try adding !important to the colour. #menu-history-clear-recent-history .checkbox-check { appearance: none !important; background: #e2cfb6; }

Thanks for that. I will look at the link.
