Firefox Community Forum

Hi,

two days ago, video embeds on Twitter stopped working in Firefox. Please help me troubleshoot the issue, so that I can either fix it myself, or present enough evidence to file a proper bug report.

Affected version: FF 140 ESR. I had some 140.7 installed when the error first happened, but have upgraded to firefox-esr_140.10.1esr-1_amd64 since. Didn't fix the problem. *Not* a snap package, regular .deb!

Affected OS: Ubuntu 26.04 LTS, not a fresh install but upgraded from 24.04 instead (which itself was upgraded from 22.04).

Symptoms: Videos on X (and Facebook) no longer play, the preview image is there for a split second, then an error appears. Video on for example Youtube is fine, though. Local players like VLC also do work as expected. Video on X worked under 26.04 before this happened.

The issue likely started when removing surplus packages and metapackages from the upgrade. According to synaptics, this is the complete list of packages removed: augeas-lenses bomber bovo clevis clevis-luks db-util db5.3-util dolphin-dev gir1.2-freedesktop-dev gir1.2-glib-2.0-dev girepository-tools gostsum granatier guestfish guestfs-tools guestmount icu-devtools jose kapman katomic kblackbox kblocks kbounce kbreakout kdegames kdegames-mahjongg-data-kf6 kdiamond kfourinline kgeography kgeography-data kgoldrunner kigo killbots kiriki kjumpingcube klickety klines kmahjongg knavalbattle knetwalk knights kolf kollision konquest kreversi kshisen ksirk ksnakeduel kspaceduel ksquares ktuberling ktuberling-data kubrick kubuntu-web-shortcuts ldmtool libaom-dev libarchive-tools libaugeas0 libblkid-dev libconfig11 libdbus-1-dev libdlt3 libffi-dev libfmt-dev libfontconfig1-dev libfribidi-dev libgd-perl libgio-2.0-dev libgio-2.0-dev-bin libglib2.0-dev libglib2.0-dev-bin libgraphite2-dev libguestfs-perl libguestfs-tools libguestfs0t64 libharfbuzz-cairo0 libharfbuzz-dev libhivex0 libicu-dev libjose0 libjson-glib-dev libjxr-tools libjxr0t64 libkdegames6private6 libkmahjongg6 libldm-1.0-0t64 libmosquitto1 libmount-dev libosinfo-1.0-0 libosinfo-l10n libpcre2-dev libpixman-1-dev libpolkit-gobject-1-dev libpsl-dev libpwquality-tools libpython3-dev libpython3.14-dev libselinux-dev libsepol-dev libspdlog-dev libsqlite3-dev libssh-dev libstd-rust-dev libstring-shellquote-perl libsys-virt-perl libsysprof-capture-4-dev libsystemd-dev libtirpc-dev libusb-0.1-4 libusb-1.0-0-dev libusb-1.0-doc libusb-dev libvirt-common libvirt0 libwebsockets19t64 libwhoopsie-preferences0 libwhoopsie0 libwin-hivex-perl libx265-dev libxdo-dev libxdo3 libxft-dev libxkbcommon-dev libxrender-dev libyara10 lskat lskat-data mosquitto mosquitto-clients native-architecture osinfo-db palapeli palapeli-data picmi qml6-module-org-kde-games-core skladnik supermin whoopsie whoopsie-preferences I don't think they are related (libx265 and libaom are only the -dev packages), but this is the only system-wide change on that day that I can remember. I of course tried re-installing these, but this also doesn't fix the problem.

On my journey of fixing this myself, I also asked the all-hallucinating knowledge randomizer frontend of OpenAI, which made me check a couple generic spots on my system and in FF itself.

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?

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

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.

H E L P ! ! !

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

I have a new mac, an M4 mini, and I set up Firefox the way I want it (the biggest ask has always been getting a bookmark to open in a new tab). Two days in, sometimes a bookmark opens in a new tab, and sometimes it doesn't. I have nothing else set up except for an ad blocker. I have not changed my OS from Sequoia to Tahoe yet, I strategically delay. It's not the end of the world. But I had strange things happen with Firefox on my other mini (an M2) in the last 6 months and I had to abandon Firefox and use Safari, which I hate. But that's a whole other topic. I've used Firefox forever, and it's my fave, and little things like this bug me. What am I missing? I set the option to False, and then reset it to True, and sometimes it works as it's supposed to, and sometimes it doesn't. So to not overwrite an open tab that has something important, I just automatically click on the 'command' key when selecting the bookmark. It's staying on my selection to 'true' and I've set it to false and then set it back to true, and restart Firefox, and I still get inconsistent results. There's nothing else that could be conflicting with this. I don't get it. Like I say, Firefox on my other mini just totally became unreliable and I had to use Safari. Any ideas? Thanks!

Firefox 150.0.1 Ubuntu 22.04

Problem: When downloading a file from a web page, the list of files and folders in the Download Panel are sorted such that file names and folder names are intermingled, rather than the "standard" folders first, then files.

Discussion: This problem has been happening for a bit now (probably 2 - 3 months or more). Unfortunately, I don't recall exactly which version of Firefox this originally showed up in. At some point recently, the default sort for the Download Panel changed, so that instead of listing folders at the top of the list of download targets, then listing files, now all items are interspersed. For example, previously selecting to download a file from a web page would give the Download Panel contents as:

AFolder BFolder CFolder AFile.txt BFile.pdf CFile.jpg

Now, the list presents as:

AFile.txt AFolder BFile.pdf BFolder CFile.jpb CFolder

I would like to go back to the previous sorting behavior, but I cannot find a way to do this. I have searched the Mozilla help articles without turning up relevant information, and I have searched the internet for web sites that might list relevant information, but either the information I am seeking is not out there (unlikely) or I am not coming up with search terms that locate the information (much more likely).

I am not even 100% sure that this is a Firefox problem (it is within the bounds of possibility that it is an OS problem), but none of my other regularly used programs show the symptom, so it would seem odd to me for it to be something other than a Firefox problem.

I would appreciate any pointers (web pages, help articles, or even just "change this in about:config) on how to resolve this.

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

Whenever i send a Tab from any Device to a Linux Desktop, the Linux Desktop is almost guaranteed to freeze. It doesn’t matter if that Linux Desktop is my "Dingus" PC with 2GB RAM and Wayland, or my "Workstation" PC with 16GB RAM and X11. On both Desktops, Firefox runs smoothly until it gets sent a Tab from another Device, then the whole Linux Desktop freezes. The Desktop doesn’t slow if i open the Tab on the Desktop in the “Tabs from other Devices” Sidebar instead.

Only my Linux Desktops freeze when they get sent a Tab from another Device. Android doesn’t slow when my Phone gets sent a Tab from another Device.

I am getting the message "updates are disabled by the admin." I am the only one here so I don't know how that happened. I need to install Slack but need to update first. I followed the steps to edit registry but still can't update. Please advise.

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

Today Firefox has suddenly started using ~20% of my CPU capacity, causing my cooling fan to run high most of the time. Since I had been running Firefox v.149.latest, I tried updating to v.150.0, but that made no difference.

It's not Firefox by itself (only Task Manager open) but whenever I open another tab with almost any website (including this one) that CPU usage spikes. What gives?!

Details: Running under Windows 10 Pro (yes, I have installed the ESU package, good until thi8s fall) on a Lenovo P1 Gen 2. Currently running Firefox inside a Sandboxie Pro v1.17.4 sandbox.

Please Help! -- jclarkw

Hi all,

After the last update the former Mozilla Test Pilot "Snooze Tabs" isn't working for me any more, I tell a tab to snooze and it just stays where it is. https://addons.mozilla.org/en-GB/firefox/addon/snoozetabs/

I've tried running with addons disabled and then running with addons active again and the behaviour is the same. It's the same behaviour whether I run from the toolbar or the context menu.

I'm presuming this problem is related to Firefox update mechanics. Any suggestions for how to get this working again please?

Cheers :)

I thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

When I press F12 to use the developer tools and try to change the width of the panes by click and drag the divider there now seems to be a limit to the panes width that was not there before. I'm not sure with what version I stated to notice this. I use to be able to drag the right hand panel fairly far over to the left and could take up about 75-80% of the width of the developers window. Now I'm guessing that I'm able to drag the right panel to a max width of 35-40% for some reason. I have not changed anything in the about:config page. I'm not sure why I can't drag the right panel to cover the 75-80% of the window that I had been able to do.

Is there a setting in the developer tools or on the about:config page that sets the max width that the right hand panel can be dragged to the left?

I use Firefox frequently as it is the most useful browser I have. I want to keep a clean desktop and do not have icons on my desktop. Every time Firefox updates, it places an icon on my desktop. I do not want it there and delete it. It is very, very annoying to have to delete every time there is an update. How can I keep that from putting it on my desktop? If the thinking is that if it gets put there, I will use it, that will be what keeps me from using it. If I cannot find a way to stop it, I will remove the program altogether and figure out a way to do the things I currently do with Firefox. Please let me know how to accomplish keeping my desktop clean.
