The new update to Firefox changed the background to black. I find it very difficult to read. Can it be changed back to white?

Hi,

  • Press Ctrl+Shift+A
  • Then a window will be open named "manage your themes"
  • There will be too many themes there on which you will see dark theme is enabled by default and all other themes are disabled
  • From there just enable your light theme.

Thank You.

The problem isn't the theme/background on the top. That is a custom ocean scene that I chose. The problem is the window or main part of the page where the shortcut icons are. The top of the page where the tabs and search bar reside is fine.

If you want to have different color scheme preference for FF UI and sites, you can change layout.css.prefers-color-scheme.content-override in about:config to 1 or 2, where:

  Dark (0), light (1), system (2) or browser (3)

For 94 default was 2, in version 95 it is 3. You can either fallback to 2 or just use 0/1 to change color preference for sites.

Dear TyDraniu, You, like so many other talented computer people with extremely well developed skill sets, automatically think everyone understands every word you write. " We don't !!!! ". You speak "computerese". My apologies but I had to coin a new word to make myself understood. I have had this conversation too many times.

"layout.css.prefers-color-scheme.content-override" is obviously the information you are trying to convey to us. "about:config" is obviously the destination. Could you give me a clue how to safely get there, and what to do when you get there?

I once taught English among other subjects. The head of the department had a rule, no text books for three weeks, at the beginning of the semester. I decided to give a lecture in communication. The principal happened to be walking by and liked it so much he asked me to deliver it to a room full of teachers on PE Day. (professional development) (I am standing at a podium; addressing a grade eleven class; with a paper grocery bag on a table beside me) Ladies and gentlemen, today I am going to make a peanut butter and jam sandwich, with your help. I have never made a sandwich of any kind, and I need some instruction. You can write down notes as we go or write it out later. It's all up to you. No need to put up your hand, just say what your suggestion is when you have a chance. This will take up the whole period so there is no rush. Everything I need is in this bag (the top is well folded). >"take the peanut butter out of the bag". I started to tear the side of the bag. > "no,no,no... from the top" I picked up the bag and dumped everything on the table. > "no,no,no... You are supposed to take it out". (everything is back in the bag) > " no take it out, by hand > "no that won't work. He's staring at the top. > "Open the bag by unfolding the top". ( it just took four people to open the bag) > take the peanut butter out of the bag > and put it on the table > and do it gently (three people to do that) Once all the items were out on the table (that took about half an hour), they began the assembly of the sandwich. > now take a piece of bread out of the bag > no! Carefully remove the plastic thingy on the bag. (I let that one slide) > reach in an take a piece of bread out I reached in and pulled out a piece. Just a piece. > okay, try it again. This time take out a whole piece. > carefully! Too late. I pulled it out clinched in my fist. Once we got around to the peanut butter... > carefully open the peanut butter do you know how many ways there are to open a jar of peanut butter. (arm pit and hand, between the legs, table, hand, and leg, etc) The peanut butter is open. What now? > Take some peanut butter out... > no, carefully take some out... So, I carefully stuck my finger into the jug, as far as it would go, and smeared it all over the bread. You see were this is going. These kids were having a ball and learning at the same time. The sandwich was just done and the bell rang. The very last thing I said to them was, " Congratulations, you just had your first lesson in computer programming".

1. Please enter about:config in the address bar to get there. 2. Please don't use instructions from above. It is outdated in the current Firefox 100. 3. Just go to menu -> Settings -> General and find new Website appearence selector. You can select Light or Dark color scheme for websites.
