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?

Sometimes, when I want to use the Take a Screenshot function (on my toolbar) to save a long section of a page, after selecting what I want and scrolling down to the Download button, the process positions the page's floating 'identification' bar across the the middle of the picture. Is there a way to set a keyboard shortcut to trigger the download command after making the selection, without the need to scroll down to see the button? This would greatly simplify the process. In some limited searching and testing, I haven't found anything that accomplishes this.

I have attached a screenshot of a page to serve as an example of how the bar is superimposed.

FWIW, this system is still running Windows 7, Firefox 115.22.0 esr.

Is there a working way to move tabs to bottom currently?

This was working until the latest Firefox update and I do not specifically remember how I had changed it last time but I believe it was via the about:config settings page but I no longer see such an option there. I tried achieving this via 3rd party plugins/extensions for Firefox but not a single one worked for the current version of Firefox. I even tried using the UserChrome.css file, as I found an article about this in the forum but it did not work either.

In the attached screenshot I have shown what I have currently and what I used to have and wish to set again if possible.

OS: Firefox version: 136.0.4 (64-bit)

I used to be able to make my own settings in Bing, but since the last update my settings are no longer stored. Each time I change them, when I open a new tab the BIng defaults are used. How do I get Firefox to accept my Bing preferences?

Hallo everyone,

after many hours of Google search and trying many changes in the "about:config" section im done with things to try so my last chance is here.

The problem i have is that videos dont play if i mouseover the firefox window or tab i.E. on the windows taskbar. The video will only start to play if i click on the window/tab and that window/tab is the "active" one im looking at.

It worked fine before but some firefox update f***ed this up (and yes the official firefox updates are the only thing that changed), no i dont know which update it was because i didnt recognize the problem right away.

The autoplay option is set to allow media and audio.

The weird thing is that when i open a video in the vlc player and do the mouseover, everything works just fine. So my conclusion is that some setting was messed up on the new firefox version.

Some data of my pc, everything is updated: - Windows 11 Pro - CPU is AMD Ryzen 7 5800X3D 3,4GHz - GPU is AMD Radeon RX 7900XT - RAM is 32GB DDR4 CL16 - Internet is wired connection with 250K speed - Firefox Version is 137.0.1

Sorry for my bad english and thank you in advance.

Hello,

I can no longer log into twitch, it says my browser isn't supported.

Before you say anything: I have the latest version of Firefox, I have disabled all addons, cleared all cache and cookies, even tried a complete, clean re-install. I can log-in in other browsers, just not in Firefox. I have disabled enhanced tracking protection as well, didn't work.

Does anyone have an idea?

Hello,

Recently I have noticed 'Your browser is being managed by your organization. - That being ImportEnterpriseRoots' appearing in settings. I have seen this mentioned by others but as of yet I cannot see if it has been sorted yet. I have uninstalled and it went away, but it has since returned the following day. I Do not have any other anti-virus on this laptop other than Windows Defender so it cannot be that. I will not be using Firefox as default until this is gone, or at the very least know that its safe.

New Tab is either the FF page or Blank? Just Like Goggle Chrome?? REALLY!!!???

If you plan to be "Chrome" by a different name, then why don't we all just move TO Chrome?

TRY not to be STUPID, Please.

My settings have this right at the top, but I am the "organizer." I am the one that set things up on my oldest laptop. When I updated the laptop with a new one, I had that message, but it was okay at that point. But now - new laptop, and I want the control back. Please guide me in how to do that.

Hello there. I had to recently wipe my computer on 4/12/2025. I forgot to sync my bookmarks and passwords. Is there any way I can possibly get these back? I don't know how far back Mozilla itself keeps files, I've been told they do but I'm not sure how far back.

Firefox now requires me to use a passkey to log in to YouTube. I don't have (or want) a passkey. My computer locks up solid, and I must reboot when I cancel the request for a pass key. I have cleared the Firefox cache and cookies. Nothing seems to help.

Firefox tanked everything I had open on my browser including job postings that I was applying to. I can't get them back. I'm so furious beyond belief! Everything I was researching - ALL GONE!!

Is there any person out there whether from the FF Staff, Developers, Community or End-Users who know how to resize the latest grotesque FF Interface of the latest download version 136.0.1? All my extensions have disappeared. The side bar is too wide. Both the Tools and Menu bars are grotesquely wide.

What is the point in Mozilla FF asking for Feedback End-Users, Community, to Contribute. if it is not going to take on board their views?

Please, do not leave this matter just to the public to deal with, You FF should deal with it for it is your product.

I would appreciate whatever help or suggestions someone may provide to an irksome problem that only happens in my preferred browser, Firefox. I've attached an image below of a page from a local grocery store. Like most stores these days, it is possible to search within that store and its web site for specific items and prices, etc. It works in at least two other browsers I've tried but not in Firefox so a setting, I'm guessing, has been changed within Firefox in the last few months (because this problem did not occur before then).

As you see in the image, I've inserted an item to find its price; and nothing happens. Before, on Firefox, and now with other browsers, I would get a display of all relevant products, prices, quantities, sales and discounts, etc.

What Firefox setting do I need to change so this information will show up again?

I have Firefox version 137.0.2 on this system running Windows 10 Version 22H2 (OS Build 19045.5737).

Sorry for my ignorance; and thanks again for whatever help anyone can offer.

When I try to install an officially signed add-on by dragging and dropping it into the browser, Firefox prompts that the file is corrupted. However, when I directly copy the file to the browser/extensions directory, the browser disables the add-on as untrusted. How can I properly install a signed extension in Firefox version 50.0b2? I can confirm that the extension works correctly when temporarily loaded (via temporary installation), but it fails to install after being officially signed.

Can't use YT picture in picture mode on Firefox when logged into my YT account. When I enable picture in picture on a video and scroll down to the comments, picture in picture mode turns off as soon as I scroll past the bottom of the video.

Happens only when I'm logged into my YT account on Firefox. Logout, it works. Logged in on Edge, it works. Logged into my second YT account on Firefox, it works. Only doesn't work for this one account.

Attached images if that helps. Last image shows exactly when picture in picture mode turns off when I'm scrolling

I use Firefox on a ASUS Vivobook running Windows 11. On April 1, it tried to update to version 137.0, but failed and led me into a update loop of sorts. I had to re-install Firefox just to force an update on it, and that worked for a bit. Just today, it decided to update... and led me into ANOTHER update loop, and it's saying that the "install failed" when I check the update history.

Is anybody else experiencing this bug, and is there a way to fix it?
