Many thanks

Thanks. I have added a closing bracket and restarted. There is no change.

First, an image showing the colour set in userContent.css when only two letters of the search are typed. https://imgur.com/fLdLN5b Secondly, an image showing the colour change to white when I type the third letter of the search. I expect the colour to remain as set in the css code. https://imgur.com/XqiZ1Wx Thirdly, an image showing the same colour change when I choose to show only altered preferences. https://imgur.com/kYlb9QR

I get the following error :

Firefox can’t find the file at jar:file:///usr/lib64/firefox/browser/omni.ja!/chrome/browser/content/browser/browser.xhmtl.

Thanks again. I added the first code below to an existing :root stanza and it is effective. If I add the second code, I get the default colour as well, as you say. I hadn’t noticed that until I changed the hover colour to a lighter blue.

I do want the colour to apply to menus inside panel menus. Bookmark menus have the set hover colour.

--toolbarbutton-hover-background: #83b7fb !important;

toolbarbutton:hover { background-color: #83b7fb !important; }

Thanks again. That does not have the desired result on my browser. The following code changes the hover colour of all toolbar buttons including bookmark items.

toolbarbutton:hover { background-color: #6495ed !important; }

Thanks. What about the toolbar buttons?

Thanks. Below is a screenshot of toolbar buttons and bookmarks shown on the menu bar. When I hover over any item, the background colour is a light grey (probably the default).

Thanks. I tried selecting every category and nothing pointed to the bookmark items. They are all folders and are on the menu bar, as are the toolbar buttons. I did find what seems to be the set of toolbar buttons but the following code has no effect on the hover colour :

#mainPopupSet { --toolbar-field-focus-background-color: #6495ed !important; }

This is what I see in the Browser Toolbox :

I marked this solved then saw a post on Reddit suggesting the following to limit code to popups : @media (width >= 700px) {…} Would it be appropriate to bracket the added lines with that?

Thank you. That had the desired result on the addons page. I have seen a post on Reddit suggesting the following to limit code to popups : @media (width >= 700px) {...} Would it be appropriate to bracket the added lines with that?

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.
