Firefox সহায়তা ফোরাম

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I'm following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

This is my second request because I can't find my original question. jonzn4SUSE has asked me to upload print screens, which are attached. Carl ([email removed from public])
