I have my login credentials saved in Firefox on a Windows PC. I just installed Ubuntu on another PC. I am signed into Firefox on both computers and Sync is enabled. When the Sync finished up on the Ubuntu PC, everything came across with the exception of the login credentials. Has anyone experienced something like this before?

how do I work with attachments in unbuntu? it greys out when trying to upload any attachments in gmail and outlook. I am new and cant find unbuntu help on latest update.

When I open Firefox through the GUI nothing happens. It acts as if I never tried to open it.

When I attempt to open it via the CLI I get:

joshua@joshua-Z390-AORUS-PRO-WIFI:~$ firefox /snap/firefox/1443/snap/command-chain/desktop-launch: line 52: /home/joshua/.config/user-dirs.dirs: Permission denied sed: can't read /home/joshua/.config/user-dirs.dirs: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 261: /home/joshua/.config/user-dirs.dirs: Permission denied cp: cannot open '/home/joshua/.config/user-dirs.locale' for reading: Permission denied /snap/firefox/1443/snap/command-chain/desktop-launch: line 266: /home/joshua/.config/user-dirs.locale: Permission denied Error: cannot open display: :0

For context: Ubuntu: 22.04 LTS

The update that I ran was simply generic system updates through the app store. Notably though it was the snap store not the ubuntu software store. Don't know if that matters.

Any ideas? Thanks a million!

When I click a link on a website, a new Firefox tab opens with this message: 400 Bad Request Request Header Or Cookie Too Large nginx/1.18.0 (Ubuntu). This is new behavior; it was working fine until yesterday. Can you tell me how to fix it?

I am using Mozilla Firefox, ver. 102.0.1, 46 bit, snap for Ubuntu 22.04. I have two issues with saving files in Mozilla.

First, when I try to save a pdf using the CTRL+S key, it open multiple (~100) instances of save dialogue box. Initially I thought my computer got freezed, since pressing the save key didn't had any effect. I tried to move it using the CTRL+SPACE key -> Move option, and then I realized there are many such save dialogue box are open. How to rectify its behavior?

Second, it downloads the file only in system created folder (e.g. ~\Download, ~\Document, ~\Pictures, etc) and not other user created folders (e.g ~\Dropbox, etc.). The dialogue box for saving file closes without giving any warning/error message. When I check the file it is not downloaded (in user created folders). Can there be any permission issue?

I have already reinstalled the Mozilla once!

Firefox 102.0 (65 bit) on Ubuntu 20.04, for some reason has begun downloading mp3 files as mpga files (Google Chrome doesn't do this). This forces me to edit the extension as I download, since my mp3 player doesn't recognize the mpga extension. How can I fix this?

In the Flatpak version of Firefox 103.0.2 the resize handles do not appear when you hover over any of the 4 edges of the firefox window unless you hold down the left mouse button, then they appear, but you have to get the mouse pointer just right before pressing the left mouse button. I notice on several forums that this has been like this for the last 2 months, are the team at Mozilla working on a fix, cheers

Hi, wonderful crew I have this annoying issue: when I want to print a page and I open the Print menu from the "hamburger" button, the preview open but on the printer list I can see only the PDF printer, not my default printer or any other printer. Also if I click on the link "Print thru the system printer window" I see only "Print on file" and "Print on LPR" I tried the same on Chomium and there I can see my default printer My system is a Ubuntu desktop 22.04 recently updated from 20.04 LTS Thank for your work

When Firefox is running and I lock the screen and unlock it again, the gui seems to be somehow broken. On the picture attached one can see a graphical issue (black frame) on the right side of the browser when resizing the window. When I try to make it smaller starting from the left, the window disappears inside the black frame on the right side. There are also issues regarding the mouse. It is not possible to see which part of the text is already selected when pressing and holding the left mouse button during text selection (no orange highlighting of the text). When I release the left button the text is selected.

This is the second PC with Ubuntu 22.04 where this happens. Both PCs were upgraded from Ubuntu 20.04, so maybe it has to do something with that.

I follow the instruction in the kb of firefox to reset the download settings. But i keep not being able to download any file from any website. I currently have the version 107 in Ubuntu. This problem occur after the last upgrade. How to fix this? Thank you.

I use Firefox sync between multiple devices, including a desktop and a laptop on Ubuntu Linux. This is done through a Firefox account. Both Ubuntu devices mentioned run Firefox 108.0 for Ubuntu 20.04 LTS.

I'm signed in on this Firefox account on my laptop (from which I'm writing this message). I recently (some months ago) changed my primary e-mail, since I may lose access to the older e-mail account soon. Now, suddenly, on my Ubuntu Desktop I received a message that I need to sign in to sync. When I click on "sign in", it takes me to tab that lists my primary e-mail address and asks for my password. I enter the password that I know is correct (it is listed under my saved logins on this Ubuntu laptop and the e-mail listed is the primary e-mail address with which I am signed in on my laptop, writing this message; it is also listed on my Firefox account details as my primary e-mail address). I then get a red message on tab stating "Primary account e-mail required for sign in", despite the fact that it is with my primary e-mail that I am attempting to sign in! I've tried it multiple times, to no avail.

At least two other users have posted about related concerns this year: (see https://support.mozilla.org/en-US/questions/1368875 and https://support.mozilla.org/en-US/questions/1395902). However, nothing has been done to resolve this issue. I have followed all instructions provided for changing my primary e-mail address. This is definitely a fault on Mozilla's side and not mine. Please resolve this urgently, users risk losing vast amounts of data, through no fault of their own, if you fail to do so.

I am using Ubuntu Firefox 110.0 (64-bit) on Ubuntu 22.04 x86_64. I am unable to play contents on Disney+, Amazon Prime Video Netflix and such. I was streaming fine until a few months ago. I have checked my settings and they are all properly set. At the time I am writing this report, the Widevine Content Decryption Module is at Version 4.10.2557.0, updated to its latest release. Obviously DRM content is enabled in settings. Changing the useragent did not solve the problem. I have seen this problem reported before for MacOs users but I could not find anything for linux users. Am I the only one having this problem? I hope someone can help. Thanks

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

I'm following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

I am running Ubuntu 18.04 and the current version of firefox is 112.0.1. The problem has occurred on two different machines.

My Friday routine normally involves updating my computers. Normally, I start firefox and get some preliminary work things out of the way before using sudo apt-get update/upgrade (sudo apt update) to update my system.

However, firefox has interjected and updated itself twice in the past month or so. When it says it has done the update and needs to be restarted, I click the button and it restarts. This would not be a problem since it was going to get updated anyway, however, when I go to start sudo apt-get upgrade to update the rest of my system, I get the following error:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

This lock traces back to firefox and persists for several hours. The first time I assumed something weird just happened resulting in the lock not being released when firefox restarted after its update. However, since this is the second time that it has happened there is something going on with your updater not releasing properly. Normally, the lock is released immediately after the updating software is finished updating, however, this is not the case with firefox right now.

Please fix this bug.

I updated Firefox and an old version remains on the "show applications" screen. I suspected it might be another profile, so I went to about:profiles and removed it, but it's still there. As I am relatively new to Linux (Ubuntu specifically), I would appreciate some help with this issue.

I want to attach a file and I click on a button (everything works perfectly on Chrome). When I click, in the console I get this error:

(firefox:3264): Gtk-WARNING **: 13:52:46.781: Can't open portal file chooser: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: L’interface « org.freedesktop.portal.FileChooser » n’existe pas pour l’objet à l’emplacement /org/freedesktop/portal/desktop

Of course, nothing happens when I click. I have Ubuntu 22.04 and apparently Firefox in installed with snap, and I have this problem since snap is used to install Firefox.

This message is the last I'm writing before I definitely move to Chrome. I hope I'll get the help I couldn't find on other places (I saw a lot of answers telling to deactivate snap, adding a ppa or some solutions like these).

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.
