Diễn đàn hỗ trợ Firefox

I have installed an animated theme for my home page a while back, but recently if I minimize firefox the memory usage increases until it freezes my pc completely. I know this issue has been reported as Bug 1828587 2 years ago and it is said that it is fixed, but here I am experiencing the same thing. I would appreciate any help since I am not that good at coding a css file. Here is my userContent.css code if maybe i set something up wrong:

@-moz-document url("about:newtab"), url("about:home"), url(about:privatebrowsing) {

   /* Sets background image and autoscale image to browser window. */
   body {
       background-image: url("wallpapers/wallpaper.avif") !important;
       background-size: cover !important;
       background-repeat: no-repeat !important;
       background-attachment: fixed !important;
       background-position-x: center !important;
       background-position-y: bottom !important;
   }

   @-moz-document url("about:newtab"), url("about:home") {
       .top-site-outer .title {
           color: white !important;
       }

       .logo-and-wordmark .wordmark {
           fill: white !important;
           color: #00aaff !important; /* fallback for text */
       }

       .context-menu-button.icon {
           fill: white !important; /* for SVG-based icons */
           color: white !important; /* for any text-based fallback */
           opacity: 1 !important; /* ensure visible even when normally dimmed */
       }
   }

The second part is to make some of the text on my homepage white so it is visible.

Hello Long ago I turned off search in address bar. Today it decided to resume search on that area. I searched help and the followed instruction for about:config. I've and see I've already set as required "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" it is set to false. What do I do to fix this. I really find search in address bar confusing.

I keep receiving a popup seeming to be from McAfee security regarding a virus on my computer. It isn't from that security firm. The ad locks my system till I shut off and restart my computer. This is very annoying and occurs on all installed browsers. Is there anything I can do about this annoying thing?

My address bar disappeared. I can get it back by hitting F10 but it doesn't stay. How can I get it back and keep it? When I go to the Customize Toolbar setting, the address bar is not there.

Hello,

I had my work email as my primary and used asimha.cloud@gmail.com as my secondary email. I'm no longer with that company and don't have access to that email. I'd like to use asimha.cloud@gmail.com as my primary email. The work email in question that has to be removed is - simhaaj@vmware.com.

To communicate with me, you can email me at asimha.cloud@gmail.com

Thank you. Ajay

Not sure if I need to reinstall. I have an account. I'm looking for the page with the checkmarks (hide people you know, wants to be friends, delete entire right side, etc. There have been an overwhelming abundance of ads sneaking into my feed. Should I re-install? Actually, I tried but nothing gets updated. Mostly, I have relied on F.B Purity probably 10+ years. And now I don't know how to revive it.

I would like to remove the search options from the address bar because I preferred the old setup with a separate search window (and the address bar was just unable to perform searches). How can I set this up?

Error message: the bookmarks and history system will no be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried following the directions in "learn more" but to no avail. Please help this senior citizen get his bookmarks back! Thank you.
