Firefox 技術支援討論區

Hello,

Since some days I can't upload or download anything using Firefox. Right-click on an image and click "download" - nothing happens. Right-click on a web page and click "Save Page as" - nothing happens. Try to upload a file to DropBox or Google Drive - no popup appears, no error message, no response whatsoever. Opening the downloads list in the browser and trying to open the folders where I had previously downloaded things (when downloading was still working) also has no effect - the folder does not open on the desktop.

So apparently the problem is some kind of broken interaction between Firefox and Ubuntu (Nautilus?)

Downloading and uploading works normally with wget and Chromium.

Steps already tried: - Resetting all browser data - Refreshing the browser - Activating troubleshooting mode

Firefox: 113.0.1 Snap canonical-002 1.0 Ubuntu 22.04.2 LTS

Hi!

Let's start by saying that I love Firefox, that I use it as my primary browser everywhere and I love that is not based on chromium. However, for reasons to me unknown is missing a very important feature (natively at least): tab grouping. This feature is extremely simple to implement and in today life, where in most jobs (I'm a researcher) you have to deal with a tons of tabs opened in your browser, being able to effectively organize them is a must.

My question is: has Firefox the intention to implement (again) this feature? Will this happen soon?

I'm really trying my best to not switch to a competitor browser and I really want to support Firefox and hope that it gains more and more users. But for this to happen it really needs to be on par with time. How come every other popular browser has a very good tab grouping feature and Firefox doesn't?

Please, let me know if there's a chance to see this feature implemented in reasonable times. Sooner or later, you will probably have to do that reagardless.

Wish you the best, A.

Hi,

i have set my home page to blank. Recently i noticed, that when i start firefox and visit a site, my arrow history (i don't know what it's actually called; the linear browsing history you navigate using those arrows) has the blank page as first entry. I don't want that first entry. How can i get rid of it? (And why is it called "chrome://browser/content/blanktab.html"?) When i open a site in a new tab, i don't have that blank page entry in the arrow history. So it seems like it must be possible to get rid of it.

Same problem with private browsing. The first page is always "about:privatebrowsing".

I'm using Firefox version 108.0 on Linux Mint.

It's only a small annoyance, but i really appreciate being less annoyed.

Thanks

for some time I've noticed this loss of frames when watching YT videos and YT notification drop down is activated. MX 19 Linux desktop MX 19 Linux laptop

I haven't seen any posts on this issue via search

Is this a driver, plugin, .. issue ?

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

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

Malwarebytes & Privacy Badger appear not to be working, though shown as 'enabled' in 'Extensions'. No blocked content is indicated. Adverts appear on lse.co.uk which can cause all four CPU's on Intel i5 to hit hi 90%. This problem appears to have started in this release.

Have disabled Privacy Badger and installed Adblocker Ultimate. This seems to have cleared the problem and Malwarebytes Browser Guard is now reporting results. Can't see how to mark problem as fixed??

A further observation which may be related to this problem. Response time seems very sluggish on FF 112.0.1

I have re-enabled both Privacy Badger & MalwareBytes and disabled Adblocker Ultimate. Both appear to be functioning now.

I have noticed that the WebExtensions process can consume as much and sometimes double the CPU & memory resource as that needed for the Firefox process. Is this to be expected? Do I need these extra security features, or are they built-in to the browser anyway?

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?

I've been searching for a way to hide the tab bar and reclaim that space. Some sources on the web set to change some settings in about:config and edit userChrome.css, but this did not work. This question links to an add-on to do it, but the link is broken:

I want to print 1 page of a pdf document from the web. I want to print 2 pages per sheet. This works when I print the first sheet on the left side, but I can't print 1 page to the right side. There is no 'right to left' option. Does anyone have a work around? (If I use the 'print using system dialog' option, the orientation of the second page is wrong. ie while the left page is correctly printed as an A5 portrait on the left half of my A4 sheet, the right half prints as an A6 sheet rotated 90 deg. The system is ubuntu 20.04.) The documents I'm concerned with are bank statements which I shall not past!! I attach another random example. Left page printed directly from Firefox, right page using system dialog.

Hi,

I'm trying to configure equipment on my local network. Some of the equipment does NOT support https. Firefox continuously changes the address http://192.168.xxx.xxx to https://192.168.xxx.xxx, and the connection fails!

I have tried the various options in HTTP Only Mode, including entering Exceptions. I have also temporarily changed network.trr.mode from 5 to 1 (and 0), but nothing is working!

What can I do?

Thanking you Pedro

After I log into my account on citi.com, I end up on https://online.citi.com/US/ag/dashboard. Even after the page is finished loading, and with a new blank profile, the CPU usage is very high. I ran it through the profiler for a few seconds and this is what it shows: https://share.firefox.dev/3MpVQi7 I didn't include the following since it's online banking and didn't want to risk exposing anything, but if any of these need to be provided let me know: Include hidden threads Include hidden time range Include screenshots Include resource URLs and paths Include extension information

Can you tell what's causing the high CPU usage and how to stop it?

Thanks

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 have a few websites, among them glovoapp.com and work Kibana, that don't open properly in my regular Firefox session any more even though I tried to remove cookies related to those websites and anything else I could think of. They work fine in private window but it means I have to authenticate each time. What steps do I need to perform to completely clean a website settings from Firefox memory?

In case of Glovo (and several other websites) in regular Firefox session there's an error: Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src"). Same doesn't happen in private window.

In case of Kibana (and several other websites) in regular session Firefox somehow remembers old authentication - it doesn't ask for new credentials and doesn't send Sec-Fetch-User header (which results in Kibana throwing HTTP 405 Method Not Allowed). In private window the header is sent correctly.

I'm using Tridactyl so I tried to use the :sanitise glovoapp.com command which, in theory, should remove everything that can be removed with API calls as described on https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/browsingData/DataTypeSet - it's not enough.

I have problem with video shuttering on youtube and other services after pausing and resuming video, and sometimes after skipping backward/forward. If I don't pause video then it will be working perfectly fine. When lagging is happening, I can put video +- 5 sec and everything is ok again. I tried disabling hardware acceleration and deleted .mozilla directory from Home to get everything to default, but it did't helped. Lagging have around 30-50% possibility to happen after pausing. Sometimes pausing don't break anything. In chromium browsers problem do not exist but I prefer to stay on Firefox. Thank you in advance for any leads

I'm trying to migrate from Chrome to Firefox browser. I cant load Twitter and some other links. I get error message. JavaScript not enabled. I can't find a setting anywhere to enable it. Help!!

Firefox (113.0.1 (64-bit), Mozilla Firefox Snap for Ubuntu) won't open files in a filesystem other than the filesystem on which my home directory resides. I have a second filesystem mounted at /970 but trying to open any file whose URL starts with file:///970 elicits a "File not found" error message, e.g. "Firefox can’t find the file at /970/stuff.jpg". Setting security.sandbox.content.level to a lower number (I've tried 0, 1, and 2) does not fix the problem. I didn't have this problem with earlier versions of Firefox; it started after I upgraded to Ubuntu 22.04.2 LTS (x86_64)which got me a newer Firefox as well. Chrome continues to open files in /970 with no difficulty.

mount information for / (which includes my home directory) and /970: /dev/nvme0n1p2 on / type ext4 (rw,relatime,errors=remount-ro,stripe=32) /dev/nvme1n1p3 on /970 type ext4 (rw,nosuid,nodev,relatime,x-gvfs-show)

I deleted the email address associated with this account a while back and wish to delete the firefox account too but as I have no access to the email I cannot verify my account to delete it. Is there a support line/email which I can contact?

Using Firefox to open an html file (in fact any file) on a mounted NFS volume gives an "Access to the file was denied" error. Also apparently related problem when trying to upload files from the same location to a web site, the access hangs. I have to copy the file to my local drive and upload from there. I assume these are aspects of the same issue. No problems using Chrome.

Mount point permissions look fine:

chris@Home:~$ ls -la /shared/ total 124 drwxrwxrwx 24 chris chris 4096 Feb 28 13:06 . drwxr-xr-x 21 root root 4096 Aug 6 2022 .. ...

I tried Firefox troubleshooting mode but this was no better. No other programs have a problem reading or writing to this volume, so I assume it's Firefox specific.

I read about problems with the snap package but I don't think this applies here.

I tried setting security.fileuri.strict_origin_policy to false as suggested elsewhere, to no effect.

Any ideas much appreciated!
