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).

OS: Ubuntu 20.04 Firefox 113.0(64 Bit )

I am building a website on my hard drive just using files. EX: file:///home/username/notes/main.html <a href="/home/username/folder/file.txt"></a>

I put an anchor link in the html source , and when I click on it I want it to open file.txt with gedit. I can get c files to do it , but .txt files open in Firefox.

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 am working on a new computer with Kubuntu and have FF installed via .deb.

On my previous computer, I could drag files from the downloads dropdown (eg download a file and then drag it into gmail as an attachment).

Now this is not possible. Instead, I need to go to the downloads folder in order to drag and drop a file. An extra step and rather annoying.

The problem is persists in Safe Mode.

Is there any way to get the old functionality back?

I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

When I print to a PDF file, Firefox changes internal links (#go-there) to full external links (either https://the.website.tld/paper.html#go-there or file://home/me/paper.html#go-there).

This is obviously wrong, since the links are internal to the document.

How to I change this behavior?

Thanks.

In case user network namespace are disabled on linux, fork return ENOSPC, as the user network namespaces are exhausted (as the limit is set to 0 [1,2]).

It would be great if there would be a work around for such a situation that user network namespaces are disabled. It would be even better if firefox could handle that situation gracefully and run without `CLONE_NEWNET` automatically.

The output is:

``` [Parent 5699, IPC Launch] WARNING: fork() failed: No space left on device: file /builddir/build/BUILD/firefox-112.0.2/ipc/chromium/src/base/process_util_linux.cc:273 [Parent 5699, IPC I/O Parent] WARNING: Failed to launch tab subprocess: file /builddir/build/BUILD/firefox-112.0.2/ipc/glue/GeckoChildProcessHost.cpp:800 ``` Note that " No space left on device" is wrong, it is about the limit in terms of user network namespaces.

Best, David

Cuando maniobro un poco con Google Maps (acercar o alejar el mapa, sobre todo, pero también simplemente moviéndolo) se me cuelga; no Firefox: todo el sistema, tengo que reinicializar la máquina, porque no me funcionan ni el ratón, ni el teclado. Y eso me ocurre desde hace mucho tiempo -quizá dos o tres años-, no es de ahora.

Mantengo siempre actualizado el sistema operativo (Linux, ahora Mint, pero hasta hace un año fue Ubuntu; si bien Mint está basado en Ubuntu) y Firefox. Ya no sé qué hacer: me resisto sustituir Firefox por Chrome; llevo muchos años, prácticamente desde que existe, usando Firefox y siempre me ha dado un resultado estupendo, pero esto de Google Maps me amarga la existencia. He intentado utilizar Open Street Map, pero ni de lejos tiene la funcionalidad de Google Maps.

¿A alguien más le sucede esto? ¿Alguna solución?
