Let's imagine that I'm trying to access a server on port 80, let's call it http://example.com:80 . I'd like to see if that site is actually active. When I try and do that Firefox instead goes to https://example.com:443 . In my example, that's actually a completely different site that I do not want to access (for completeness port 80 is used for certificate renewal of a whole bunch of different names that are all set up on other ports, of which 443 is one).

In both a regular Firefox browsing window and in a private browsing window, Firefox decides to access https://example.com:443 instead of http://example.com:80 , despite me explicitly typing "http://example.com:80" in the URL bar.

How do I prevent Firefox from doing this when I explicitly request an http site?

I've been missing scrollbar arrows on my Mozilla Firefox browser for a long time now, which makes browsing and engaging with various websites more difficult. Can anyone tell me how to restore the scrollbar arrows?

When I scroll some sites with the touchpad, it doesn’t scroll smooth like on windows. It scroll brutally 3 lines after 3 lines. I can’t scroll a half line for example. Even if I activate “smooth scrolling”, it doesn’t scroll with the precision and the speed of the hand. I don’t if It’s a mistake in the code of gecko or in the code of firefox but could somebody fix it?

In recent Firefox versions, the behavior of window.open() has changed. When opening a new window with an empty URL (), Firefox opens a blank tab (about:blank) and then loads the specified content. However, the about:blank tab may not close automatically as it did in earlier versions.

Hi, so basically for the past few days my YouTube Premium has randomly stopped showing me my YouTube Music and it refuses to work. The page still loads, it just doesn't play any songs. I've tried reloading the page, checking my internet connection, resetting the browser & computer, clearing cache, deleting cookies, turning off all my extensions, signing out, doing everything I can really think of and it's still not working. When I check on Chrome and on mobile it's perfectly fine, so I have no idea what the issue is. I've tried to see if other people have had this issue as well but they either never got answers or I tried a solution and it didn't work for me. I have the latest version of Firefox as well. Could really use some help, thank you !

When attempting to view certain formulas on TurboLearn.ai, they fail to display properly. I am honestly at a loss since a bunch of other formulas display properly.

Since the most recent update (137) I have been having an issue where when I switch tabs to an existing open tab, occasionally that tab will be moved to the end (far-right) of the list of tabs. I find this extremely annoying as I often am using tabs to organize what is related to what, and this is undoing my organization.

I can't quite see what the exact trigger is - it's not every time, but it fairly often. It sometimes happens when I try to 'switch to' my current tab, and sometimes it will happen when I'm switching to a different tab.

Since the latest stable update, I have not been able to shift click or control click multiple entries on the history tab to delete entries.

I have to click the trash icon on each item now and its very time consuming.

Is this on purpose? is there a setting to revert to the old way?

TIA

Whenever I close a tab, an annoying blue box appears offering to undo the close tab action I just did. This is something that just started. I want to disable it. I have used Firefox for years but find this intolerable.

I ordered something recently with UPS tracking. I noticed that the tracking number always results in "We are unable to complete your tracking request at this time. Please try again later" message.

But, if I track it using Incognito mode, or in my Firefox mobile browser, it does work. It also works in the mobile version of Firefox.

I have troubleshooted by restarting Firefox in troubleshooting mode with no luck, thinking it was an extension or something else installed after the fact that was affecting, but it doesn't appear to be that.

Anyone else experiencing this issue?

Version Affected: Firefox v137.0 for Windows.
