Firefox Community Forum

after the last update of firefox, the default firefox home page doesn't load. Instead, I get the message: Oops, something went wrong loading this content. Any ideas?

Hello! I can't login to my x.com account from Firefox 115.35.2esr on Windows 7 SP1. I'd was stay logged in many years before I accidentally clear my cookies. And now I can't login. It just reloaded input form when I type my login and press "Next"button. I tryed login from Private mode, I tryed to disable all addons. Nothing helped. But I still can login/logout from Firefox 140.10.2 on Windows 11.

In Firefox console I see

errors [ {…} ] 0 Object { code: 399, message: "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1" } code 399 message "Could not log you in now. Please try again later. g;177706962260066684:-1778241640627:geToqptptoIvemMOHotwS0TF:1"

and

Corporate Policy: Skip unsupported function name "identity-credentials-get"

Can anyone help me to fix it?

On all other browsers the drop down menus still show after first use, except in Firefox - where after first use they disappear and you have to go back to Home to re-show them.

I have tried the suggestions give for configuring the site iin Elementor/Wordpress but none have solved the problem and I can only assume the answer lies in Firefox settings.

TIA

When I click Bookmarks > Manage Bookmarks I'm taken to Other Bookmarks where I never store anything. I'd delete it if I could but it doesn't appear to be an option, so instead I'd like to taken directly to Bookmarks Menu. I came across this post from just over 4 years ago which sounded like it's exactly what I want, but it doesn't work. Are there any changes anyone can suggest that would allow it to work in 2026?

You can use the autoconfig.cfg file in the Firefox installation folder to initialize (set/lock) preferences and run privileged JavaScript code. In this case code to open the Library with the Bookmarks Menu folder selected. You can modify the showPlaces variable to open any of the four possible root folders (in this case [1]).

To use Autoconfig, place two files into the Firefox installation directory.

   on Windows and Linux, they go into the same directory where Firefox is installed
   on macOS, they go into the Contents/Resources directory of the Firefox.app 

The autoconfig.js file that specifies to use autoconfig.cfg is placed into the "defaults\pref" directory where the channel-prefs.js file is located.

The autoconfig.cfg file is placed at the top level of the Firefox directory.

   autoconfig.cfg and autoconfig.js need to start with a comment line (//)
   autoconfig.js needs to use Unix line endings (LF instead of CR/LF)

     elm = document.getElementById("Browser:ShowAllBookmarks");

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

This issue just started today.

I was attempting to watch a video on patreon, and normally I pop out the video so it is larger. This normally has no issues.

But today when I hit the button to pop it out, Firefox crashed.

Firefox then updated, so I thought maybe it was just because it needed to update.

I attempted this two more times with the same result. 

The first like I normally do where I start the video and then click the "pop out" button. Then the second time with the video paused. The minute I click the pop out option Firefox just crashes closed either way.

Hi, it looks like Firefox can copy links from selected tabs, using right-click menu. It doesn't work for non HTTP(S) addresses though, such as "file:///C:/Users/USER/etc."

Is it possible for non HTTP(S) addresses?

The add on Export Tabs URLs by AL is very good, has the option for non HTTP(S) addresses, but I couldn't get it to work for selected tabs, is it possible for selected tabs?

I have noai.duckduckgo.com set as my default search engine. Almost always (but not quite every time) when I type anything into the address/search bar, I get a page with a "Server Not Found" error. (See attached image.) Refreshing the page immediately brings up the results without issue, but I consistently get the error first.

Oddly, if I go into settings and switch to a different search engine and then switch back to duckduckgo, the issue will briefly resolve and it'll work fine for a short while... and then I start getting the error again.

Is there any way to fix this?

How do i get my original profile page to always open when i open firefox instead of a new page without my bookmaks. This started right after my visit to Mozilla so i must have changed something. I don't know what!.

I use the current version of Firefox on Ubuntu 22.04 Linux. When I scroll down past the individual bookmarks at the end of the menu, the folder names start repeating, along with the bookmarks inside them. I have three or four sets of bookmarks and would like to have only one. How can I delete all the bookmark folders below a certain point? By the way, when I install a new, different version of the operating system and sign in Sync restores all the bookmarks.

So every few days now if the free VPN is on I get my tabs locked into an error. I get that warning screen and sites stop loading or partly load, before the VPN update I never had to close Firefox this often, if left idle with the VPN on this seems to happen faster, I have left the VPN on overnight and I tend to nearly 90% of the time wake up to this error, if I disable the VPN fully I can pick up where I was but cutting it back on I have high odds that it will break, Firefox is idle while I do other stuff and the VPN is on, I get that error and I get to watch the weather app give me it's error. I have never had Firefox fight my antivirus It worked fine for ages, and only now do I need to reset Firefox by force now every 1 to 3 days. I use to be able to leave tabs open, but now they always error out in a few days. It could be other things, I just never had problems like this until now, it's so common and in the same time tables.

Using Firefox on Windows 10 Pro & 11.

Beginning in v 150.0, when a media playback occurs, the audio volume in the player gets set to its maximum level. This is true for X.com media and for YouTube videos.

For YouTube it only happens for the first video played in a new tab; subsequent videos in the same tab 'remember' the volume setting from the prior video. In X.com, every media player invoked reverts to the maximum audio level.

In v 149.x and earlier, the media player maintained the audio level from its prior invocation.

Is there a way to have the media player 'remember' its previous audio setting when it gets invoked?

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

I'm sure it's a setting but I can't figure out which one.

It has always logged me out when I close or update the browser, which is a minor inconvenience. And in that instance when I got to log in, it has indicated that a verification email has been sent to my account, and historically clicking that does the trick.

Now it does one of two things: It will either tell me to click on the verification email sent to my email account but the verification email it never arrives, or it will simply remain static, as if I never entered a password at all.

Very frustrating, please tell me which settings to change and I'll do it. Thanks!

Steps that remove my pinned tabs from Firefox:

Open pinned web app from taskbar. Open regular Firefox browser.

Any pinned tabs that were in the browser before opening the web app are lost.

Is this already reported? I can't imagine this is intended behavior.
