Forum d’assistance Firefox

Hi, I've been struggling with this for months and can't find an easy solution or a good explanation. I'm running Ubuntu 22.04 pretty basic, I don't have many custom repositories enabled or anything, just a few additional packages like slack, Teams or Chrome. Ubuntu switched Firefox to snaps as well, and I can't get internet access with it. The error message is:

--- May 12 12:16:20 nuc kernel: [12948.381392] audit: type=1400 audit(1683886580.562:131): apparmor="DENIED" operation="open" profile="snap.firefox.firefox" name="/etc/fstab" pid=7731 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 May 12 12:15:43 nuc rtkit-daemon[1030]: message repeated 3 times: [ Supervising 10 threads of 4 processes of 1 users.] May 12 12:16:20 nuc dbus-daemon[790]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.175' (uid=1000 pid=7731 comm="/snap/firefox/2645/usr/lib/firefox/firefox " label="snap.firefox.firefox (enforce)") ---

Simply stopping (and aa-teardown) doesn't work at all, Firefox doesn't even start without apparmor running. I'm not an expert with apparmor, but I wanted to set in complain mode instead enforce, but I'm struggling with that, too. I didn't touch the /etc/hosts file, the error message is a little different on another Ubuntu 22.04 computer I use, there it complains about permission denied for the resolve.conf. So I'm asking the community, how do you deal with this? Searching the web gives me all kinds of ideas, but none of them work. Could anyone help me out here?

Thanks!

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

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 often use two firefox windows each with several tabs opened

Problem is when I quit in this state sometimes only one of those multiple windows gets opened on the next launch

To quit I do a `ctrl + q` or right click `Quit` from launcher bar

Is there a setting to tell firefox to always relaunch with the same set of windows ?

I use sync and this happens when using the same computer for the exit then relaunch of firefox

firefox release 112.0a1 (2023-03-05) (64-bit)

Ubuntu 22.04

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.

If it's useful:

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 using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

Summary: Firefox fails to load many sites, and some will kill the entire browser.

I recently updated from Ubuntu 22.10 to 23.04, which included an upgrade to Firefox. I originally had trouble with tab/window dragging operations causing the entire desktop to crash.

Removing the snap and installing from the Firefox maintained PPA fixed this issue, but a number of others remain. (Detail on this part over here on the ubuntu forums if interested)

Now many google sites simply show the loading error for ever and never recover. Some URLS can kill the browser completely. For example, this one from the Mozilla website: https://support.mozilla.org/en-US/kb/websites-show-spinning-wheel-never-finish-load The error message is attached.

I am happy to perform more tests and provide more diagnostic if it will help. That same URL works fine from the chromium browser on the same desktop systems,as does every other site I've had issues with.

System details: Ubuntu 23.04 64 bit Firefox 113.0.2 Intel_R_ Client Systems NUC7i7BNH (Intel® Core™ i7-7567U) Intel® Iris® Plus Graphics 650 (Kaby Lake GT3e) (KBL GT3) Gnome 44.0 Wayland WS

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

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

Crash report submitted bp-37f84164-6125-4ae1-9e55-8a8200230225. Started happening about once a day over last few days possibly since 110 FF update (Ub kernel was also updated a few days back) Have to do a hard power off & restart

I am running Unix Ubuntu 22.04 with Firefox 104.0.01 (64 bit). My Canon LBP 6230DW works fine in my word processor and in Chrome, but it does not show up in the Printer destination field when I am in Firefox. The only print option is to "Save as PDF." How do I get the Canon to be a print destination in Firefox?

Since the upgrade to Firefox 104.0.2, the only option when printing is to select "Save to PDF". All other apps can printer to any of my printers. I have to save as a pdf then print the document using the PDF viewer. I have HP4100 & HP9025 printers on my network, that all other apps can see and print to. I've refreshed Firefox & re-installed Firefox but the problem still persists. The System's printer dialog shows that both printers are available and changing default, or reinstalling the printers makes no difference. OS is Ubuntu 22.04.1 LTS.

Screenshots show the printer window in Firefox, and the Printer Settings from the OS Settings window.

Starting today, with firefox 102 (on Ubuntu 20.04), I cannot open a url using the address bar. If I enter a url and then hit Enter, it brings up my selected search engine looking for that url, not opening the url itself. This has not happened before today. Is there a way to use the address bar only for opening addresses, and use the search bar for searching?

I have a laptop with Ubuntu 22.04. Firefox 307 from deb package works perfect. I wanted to give a try to Flatpak variant 306, which works well too, except two finger gestures back and front won't work. Scroll works. Any scheduled fix for that? Would be cool to move to flatpack completely.

Beginning this afternoon, Firefox 107.0 for Mozilla (OS=Ubuntu 22.04) is preventing me from downloading and opening PDF files. i have to use my Win 10 PC to download PDF files.

I'm using Firefox 106.0.1 on Ubuntu 22.10 from Mozilla's official PPA but when I open some websites the browser crashes with the message "Exiting due to channel error.". I found the error could be related to libwebp with LTO enabled, may be it is, but I rebuilt the Ubuntu's package without LTO and one website stopped crashing, dell.com support page, but several others still crash, like amd.com.

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.
