Firefox Community Forum

The bug exists since Firefox version 131.0 circa, when some things related to DPI had been changed, which I was able to guess because, without touching anything, the size/zoom of the content of the websites were slightly different (bigger). Experiencing this in both Windows and Xfce.

Steps to reproduce:

• Have a custom DPI settings in your operating system.
• Open a new Firefox window.
• Note how the Firefox window height is shorter, so yo can see about 20 pixels of your desktop background. Manually resizing the window and restarting the browser has no effect: the correct height is not remembered.

I've reported this one year ago in the tracker, but no one has yet done anything about it: https://bugzilla.mozilla.org/show_bug.cgi?id=1925284

Am I the only person in the world using Firefox with a custom DPI setting in the OS? I find this hard to believe. Yet I'm experiencing this bug since one years ago. I can't stand using a different browser, but having to resize the window every time is so annoying...

I'm experience trouble with firefox loading pages. It seems that some pages (about 1 in 10) will not load first try. Instead it results in either a "unable to connect", "Hmmm... Can't reach this page" or simply a blank page. I have not noticed any pattern in the pages on which this occurs and they all display correctly after a refresh. This problem only occurs on firefox. I have already tried disabling the proxy without any success. I'm looking for any suggestions for solving/diagnosing this issue.

System info: Firefox 142.0.1 Fedora 42 Linux kernel 6.16.3-200.fc42.x86_64

Hi, I'm using Firefox 142 on Ubuntu 24.04. It's a fresh install. I cannot sign in icloud.com with Firefox even though it works with other browsers like Brave. I deleted all cookies and site data and disabled extensions (KeePassXC). It doesn't help. I tried in new private window. No success. I copy my password from a password manager, so, no, I haven't mistyped it.

Here's what I do:

1. Open Firefox and go to icloud.com
2. Click on the "Sign In" button
3. Enter my Apple-ID and click on the arrow on the right end of the "Email or Phone Number" field

At this point Brave behaves differently than Firefox. See below for how Brave behaves.

Firefox: -> A "Password" field appears (no buttons "Continue with Password" and "Sign in with Passkey")

1. Enter my password and click on the arrow on the right end of the "Password" field

-> Error message "Failed to verify your identity. Try again" appears. See icloud.png

Brave: -> Two buttons "Continue with Password" and "Sign in with Passkey" appear. See icloud-with-brave.png

1. Click on button "Continue with Password"

-> A "Password" field appears.

1. Enter my password and click on the arrow on the right end of the "Password" field

-> 2FA code is sent to my iPhone -> "Two-Factor Authentication" form opens... etc. complete sign in successfully

Please help!

Unfortunately I cannot attach the HAR file from the login sequence because the password is included. However, I attached some screenshots from the Web Developer Tools. It seems to me that the login flow with Firefox is broken. I can't tell who's to blame, Apple of Firefox. The error message with Firefox is always the same, no matter whether I enter the correct password or rubbish. In Brave, however, there is a more precise error message when I enter a bad password. See icloud-with-brave-wrong-password.png

Since the update to 142, on pretty much every site it keeps jumping back to the top of the page. Happens on a lot of sites. For some reason, if I select some text at the top of the page it seems to stop this. A lot of people may not have discovered this. Mozilla just needs to fix it. I am using Ubuntu 24.04. Been using Firefox for many years. Never seen this before.

I already tried setting geo.enabled to false as suggested here: https://support.mozilla.org/en-US/questions/1475504

Is still get the prompt every time no matter how often I decline.

Under the advanced settings for fonts, there is a dropdown menu listing various scripts. These are the only fonts which Firefox can render. For example, there is no option for Coptic, so any Coptic characters are rendered as a box containing the Unicode key.

The fonts in question are installed on my computer and even show up in all of the dropdown menus; Firefox just can't access them.

Firefox does not display thumbnails for some photos I've uploaded to Proton Drive. I can view the photos normally when double-clicking on the thumbnail placeholder, but the thumbnails themselves do not appear.

Note: this is not the case for ALL photos (all are JPG format), only some. Proton help desk claims this may be due to Firefox privacy protections, but disabling those protections for their web site has no effect.

As part of my maintenance process, I have a utility that travels the entire file storage on all computers. Yes, it takes time but is necessary.

My problem is in the home directory is a .mozilla directory and. while processing the directory to the bottom, my process is attempting to look at files that don't exist! An example is: .mozilla/firefox/tar3lacg.default-release/storage/default/https+++www.youtube.com/cache/morgue/97/{71caaab5-6413-4293-ad75-dd3a833ae461}.final

There are a completely unreasonable amount of these files and they just don't exist on the computer! It is causing my error logs to fill up with useless information that is taking way, way too much of my time. Obviously, I can't delete non-existent files, so there seems to be no easy fix. I tend to think these are soft links to these non-existent files, making them broken and therefore problematic. That seems to be the only place where my process can find the names of files that don't exist.

Can this be verified? Can I be let in on the secret place where they can be found and eliminated?

Hi there, I'd like the option to unbind default keybindings. Specifically, the Ctrl+W to close a tab binding. I reflexively hit ctrl+W when I want to delete a word in a text box (from emacs/shell/vim/etc) and this has resulted several times in me closing the tab I was on and losing the text I was writing. It would be useful to me to be able to disable this keybinding so that I don't continue having these accidents. More generally, I imagine that some users will find some keybindings annoying and want to disable or maybe remap them.

So this is half a feature request, and also half a support request if anyone has suggestions for workarounds in the meantime.

The other day I attempted to use a script in the Greasemonkey extension, which would not work for me. I deleted the extension in the end, but in the process of trying to get it to work, I disabled all other extensions for a time to test what the problem might be.

Ever since then my profile seems to be corrupted in some way. I have refreshed Firefox, as well as made a new profile to test where the error must be. As soon as multi-account containers is reinstalled, the problem returns. This includes the fact that yesterday, for unrelated reasons, I decided to install Linux Mint for my OS and stop using Windows - as soon as I signed in my Firefox account and the profile synced in the new OS, the error returned. (The attempt at refreshing Firefox was done after installing Mint; the test profile was done on Windows.)

This is the behavior I'm seeing:

- I cannot drag a tab that's logged into a different container into a tab group with tabs that are not signed into any container. This includes tabs logged in on the Facebook container. - In fact, I cannot drag any tab that is logged into a container anywhere - they insist on being all the way to the right in the list of tabs. - If a tab logged into a container is all the way to the right in any given window, the button to open a new tab will automatically open the tab in that container instead of opening in no container, which is my preference.

I use the multi-account container extension extensively and would like to see this fixed. If anyone has any idea of what could be happening here I'd appreciate the help!

After 11 year I suddenly can't access my Wordpress blog on Firefox. I have to use Chrome to access it - with no problems. I have been on Ubuntu Elementary for years years and have never had difficulty accessing my blog. I have uninstalled and re-installed Firefox twice, I have emptied my entire cache and cookies. I also tried to empty my DNS on Ubuntu Elementary but my version doesn't have DNS. The problem started 24 hours ago.

Srry I don't see the button to delete the question, because I didn't even differentially diagnose whether it was even Firefox or a webcam program that was running

Playing a video in a Firefox tab prevents my desktop from hibernating, even when the video is paused.

I'm guessing this is an advanced settings in about:config somewhere, possibly.

I multitask a lot so I was partway through a video on utube and paused it, & then my computer was still awake in the morning.

The simple solution : don't do that then; or, it's just a little bit of electricy, don't even worry about it.

I looked around for solutions in Debian or wherever & they talk about VLC playing, but this was a Firefox tab.

I noticed earlier this week that one of my extensions is still having a major bug, despite said bug being patched a month ago and the update being approved already. The extension was set to auto update, so I tried disabling it and checking for updates manually. Firefox said an update was available, so I hit update and nothing happened. Even after waiting 10 minutes, refreshing `about:addons` and even restarting firefox, the update was not installed. I can't check dev tools for information on what happened either since they are handled by the firefox app itself instead of the `about:addons` page. So I turned off auto update for all extensions to see if it was just that one that was having an issue, but none of my extensions have been updating. 11 updates available, none able to install. The only way I could get an extension to be up to date was by completely reinstalling it, which removes all extension data and thus is not an option.

I'm on Linux and have been using Firefox since I switched over. The first thing I disabled was restoring tabs because I never need it/find it annoying. I noticed that every time I would restart my computer with Firefox open it would restore the session. I understand that this happens because Firefox sees it as a crash so I changed the following settings:

• browser.sessionstore.resume_from_crash from `true` to `false`
• browser.sessionstore.max_windows_undo from `5` to `0`
• browser.sessionstore.max_tabs_undo from `25` to `0`
• browser.sessionstore.max_resumed_crashes from `1` to `0`

I changed those according to this guide: https://kb.mozillazine.org/Session_Restore#Completely_disabling_session_store

Unfortunately any time I restart my computer with Firefox open it resumes my session. Is there any other way to turn this off? Theres no way all of these settings do nothing.

I also deleted the contents of sessionstore-backups in the profile folder but it just recreates the files after a while.

My goal is to be able to restart and shutdown with Firefox open and not have to worry about it restoring tabs.

Hello Mozilla. Recently my wife and I have had a new experience with our bookmarks. When we display a list of bookmarks, part of the list runs off the page, so, we cannot see the complete list.

In the past, when we would request this list, if it was too long to display downward, it would then automatically shift upward, so that the entire list could be seen.

Has this feature been dropped or altered in anyway? Is there anything we can do to regain the feature?

We are using Ubuntu 24.04

Thanks. Curt
