Diễn đàn hỗ trợ Firefox

i have uninstalled, reinstalled many times. I cannot load the program once it has been uploaded to my laptop. always get error that it cannot find the URL. ICON shows up on desktop but clicking on it just brings up that error.

I recently updated my Mac OS to 15.4, and for whatever reason, ever since I did, Firefox stopped working. I can open it, but if I try to go to any web site it just has a dot bouncing back and forth like it looks like it's trying to go to the site, but then it times out. I have deleted and re-installed Firefox several times - the last one being version 137.0.2 for Mac, but it still won't open any site. I don't know what to do to get it working and Mac tech support had no ideas other than to contact Mozilla tech support, so here I am. Can you help me? This has never happened before and it makes no sense that it would not work. You can see by the enclosed screen shot that it opens, but fails to open any photos or go beyond that. The 'checking for updates' alert just keeps spinning and spinning. Rick Garside

in latest version of firefox this https://support.mozilla.org/en-US/questions/1367908 no longer works

How to disable Ctrl-T?

Sorry if this has been resolved before, but I would like a way to disable moving tabs around within a single browser. I'm accidentally pulling them off of their original spot when clicking without realizing it, and feeling like an absolute dingus for moving it back dozens of times a day.

When I paste an URL in the address bar with Ctrl+V and then press Enter before releasing Ctrl, the page is opened in a new tab. How can I disable that? I want it in the same tab. (If I release Ctrl and then hold it again before pressing Enter, it opens in the same tab already.)
