Firefox Support Forum

When I went to start firefox today on my MS Windows computer, I got a file error message saying pathway was corrupted (or something like that) and then the firefox app disappeared from my pinned toolbar. When I went and reinstalled it, all of my saved bookmarks and passwords were gone. How do I get them back?

New install of Firefox set up with a 'wrong' email account. Tried to use the 'Mozilla account' page to fix this by using secondary email and then making it primary. But the secondary email I want to use is not allowed by Firefox giving an 'Account already exists' error. What should I do?

I'm new to firefox and would like to set cloudflare for DNS over HTTPS but there seems to be an issue. If I set it to NextDNS the connection stays active. But if I set it to cloudflare it goes inactive with the error (NS_ERROR_NET_TIMEOUT_EXTERNAL). I tried setting a custom DNS to OpenDNS and got the same error.

I'm running Manjaro Linux if that make a difference.

How can I troubleshoot and resolve common issues with my Mozilla Firefox browser using the resources available on the Mozilla Support website?"

Hello, I'm looking for a way to add a shortcut, similar to:

CTRL + Click = open link in new tab SHIFT + Click = open link in new window

What I want it to do is open a link in a Private mode window, to avoid having to open the right-click menu.

I came across this person asking for something similar (they specifically want the private window to not appear on top, I do not care if it gets automatically focused or not) https://support.mozilla.org/bm/questions/1317416

The only answer links to a list of "command line options" and points to the private ones. I understand how you can use these to change how the Firefox shortcut behaves, or to open Firefox in a specific way from the "Run" command, but I do not know how, or if it is even possible to apply these settings to a specific shortcut-click combination.

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn

I've had this issue ever since switching to a new laptop. This issue is specifically within Firefox (I have tested this in other browsers and programs, and the issue isn't there. Everything else works perfectly fine!)

Essentially, whenever Firefox plays multiple sounds at the same time (for example, I use both youtube and discord in-browser) the second sound will briefly mute the other sound. (Going back to the discord-youtube example, if I am watching a youtube video and recieve a discord notification, the youtube video will pause for about half a second.) Or if a site has background audio but also plays a short audio clip when certain elements are clicked, for example, it will cause this "overlapping" issue. Again, this issue is only within Firefox.

I am using Windows 11 if that helps. I've already tried using a Firefox Refresh and peeking in about:config but I'm totally lost as to what I can try next, since I can't find any other examples of people with this issue online. Sometimes the issue briefly fixes itself but then reappears.

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

Everytime i try to watch a video it says it can't play or it just sits there buffering. Youtube works but only lower quality, but every other site i go on doesn't. Twitch won't load, other sites show Error Code: 102630. This is only a problem on my browser on my windows pc I have. On mobile the browser works great and has no problem showing videos so it a problem for my pc browser.. I've tried all of the steps, i've updated, i checked drm and even went into config to check there. But nothing works, it still can't load videos. I have version 125.0.3 and for me it's the latest one. I even turned off all of my add-ons to check if it works or not but nothing there either. It worked before, just now the latest two months it hasn't. What can I do in order for the videos to load? Thank you for your time.

I use Firefox as my browser and used to be able to go a web site or to a link from an instructor and when I clicked on the link or entered the class I was attending, the Zoom meeting would automatically open. That doesn't work anymore. I have to "join via browser but I don't have the meeting id. Why has this become so difficult? Zoom denies being the problem so now I wonder if it's the browser.

I have accidentally end up with two FireFox accounts. I want to combine them, but I can't change either account to the other one because FireFox tells me that the replacement email/account is already in use. How do I get around this?
