I am trying to have Firefox show an "X" on every tab as soon as I hover above it. I followed a certain article and implemented this code:

/* Show Tab Close buttons only when hovered */

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 visibility: collapse !important;
 opacity: 0 !important;
 transition: all 250ms ease-in-out !important;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]):hover > .tab-stack > .tab-content > .tab-close-button {

 visibility: visible !important;
 opacity: 1 !important;
 transition: all 250ms ease-in-out !important;;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 display: -moz-box !important;

}

This code is however not being implemented no matter how many times I restart Firefox. 'toolkit.legacyUserProfileCustomizations.stylesheets' is set to True The location is userChrome.css is '/home/user1/.mozilla/firefox/yqomjsh9.default-release-1672744596809/chrome/userChrome.css'

What could be the issue? I tried adding executable permissions using "chmod" but that did not change anything.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

I have my setting to ask me what to do with files, pdf , whether open or download i have it all set to ask it asks , it opens them in firefox but still downloads them to my computer. i don't want them to download , i'm never sure if they are safe how i stop stop auto download This has only been in the last few updates this began

For the past week Firefox has been opening Youtube in dark when for the last decade I've been using light. Every time I change to light it works for that tab, if I open a new tab and load Youtube it opens in dark appearance. When I change to light and then click my avatar in the top right of Youtube it's still states I'm in dark when it's in light.

Why doesn't the light appearance stay? I've cleared cookies and that doesn't seem to work. It's also specific to Firefox, this doesn't happen in Microsoft Edge.

Hello, I was wondering if there is any way for firefox to not open a new window when i click a link? Instead, it would open a new tab, not a new window.

if there is any way to do this, please tell me

also, how do you make your bookmarks show while in a site?

thanks guys!

I had the extension for Dashlane working on Firefox. It looked up and I removed it. Now I cannot locate the Extension when I select Themes and add-ons and search for Dashlane. Any suggestions? Thanks in advance,
