Fóram Tacaíochta Firefox

Firefox consumes a lot of processor time in background. How to disable it?

Following options do nothing: Use recommended performance settings - dasabled Use hardware acceleration when available - disabled browser.tabs.remote.autostart = false

After some time of idle, i.e. leave the computer for some time, say over night. No suspend or hibernate. Back to the computer next morning, unlock. Then Firefox appears frozen/hang, can't switch tab (clicking tab has no response, but not really frozen, sometimes responses after dozens of seconds of lag), page also has no response. Then after around half to 2 minutes, everything back to normal.

During the "hang", CPU load is load, no memory stress (swapping/paging).

Environment:

Firefox 123.0 (64-bit), (actually it bothered me for years)

Linux 6.6.15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.6.15-2 (2024-02-04) x86_64 GNU/Linux

``` lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux trixie/sid Release: n/a Codename: trixie ``` Not related to particular Linux and/or kernel version.

CPU: Intel or AMD, not related. RAM: 64GB/96GB, free memory more than enough.

I will gather more detailed info later.

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

When I scroll up or down on the touchpad in firefox, it is like I scroll past a certain threshold, and it then sends a "scroll up" or "scroll down" command.

When I do this is Chromium, it's like I'm moving the website with my fingers. Similar to how it would be on a touch screen. In other browsers, the scrolling is not discrete, but continuous.

I love firefox, but this is driving me mad when I'm browsing. Is there any fix for this?

Hi

When I scroll text for some reason, Firefox stopping scrolling very slow. It's almost take up to 2 seconds. Very annoying smoothest. I have stopped scrolling already but Firefox still scrolling and finally very slow stop it. I can't focus on the text because it's still slows down the scrolling.

How to fix that!?

I'm running Firefox 123.0.1 on Linux Mint 21.2. Something changed after my last update. I visit a number of web sites at which I scroll down a window to a link, click on it to open it, read that link, and then return to the previous page. Examples are news sites like slashdot.org, associated press, or arcamax. Firefox used to return to the place in the original site page where I had clicked on a link. Now, it returns to the top of the original site page, and I have to scroll down again to where I had clicked on a link. I can right click on a link, open a new tab, and then close that tab, but that requires multiple clicks, and I used to just click/click. Is there a way to set up Firefox to go back to the previous behavior? Thanks in advance. ;

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

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?

Hi,

  I am running the latest Firefox v122 (firefox_122.0+build1-0ubuntu0.22.04.1~mt1_amd64.deb not snap)

and when using the --profile option to specify the startup profile it fails to start even on a NEW system that never ran Firefox if I give it a directory that resides on a mounted ext3 filesystem.

  All the permissions are OK and yet running strace I see an error and after a few second will get the

generic pop-up with the error message: (after a few seconds)

Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

 Running the SAME from /tmp works fine, but I need the profile to reside on a persistent storage area

so if the LIVE distro restarts then it can restore the previous session, bookmarks, options, etc...

============================================================

 The 2 directories were created identically and have the exact same permissions:

xubuntu@xubuntu:~$ mkdir /tmp/firefox3

xubuntu@xubuntu:~$ mkdir /media/xubuntu/sys_n01_home/mozilla/firefox3

xubuntu@xubuntu:~$ ls -ald /tmp/firefox3 drwxrwxr-x 17 xubuntu xubuntu 1080 Jan 21 22:05 /tmp/firefox3

xubuntu@xubuntu:~$ ls -ald /media/xubuntu/sys_n01_home/mozilla/firefox3 drwxrwxr-x 17 xubuntu xubuntu 4096 Jan 21 21:13 /media/xubuntu/sys_n01_home/mozilla/firefox3

============================================================

The only difference is that one is mounted on tmpfs and the other is on /dev/nvme0n1p2:

xubuntu@xubuntu:~$ df -k /tmp/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 32560016 351528 32208488 2% /tmp

xubuntu@xubuntu:~$ df -k /media/xubuntu/sys_n01_home/mozilla/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on /dev/nvme0n1p2 195751828 51056068 142695768 27% /media/xubuntu/sys_n01_home

============================================================

When starting firefox with the /tmp/firefox3 profile directory it works fine and starts up:

xubuntu@xubuntu:~$ firefox --profile /tmp/firefox3

newfstatat(AT_FDCWD, "/tmp/firefox3", {st_mode=S_IFDIR|0775, st_size=1040, ...}, 0) = 0 newfstatat(AT_FDCWD, "/tmp/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/tmp/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=-487933736}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0 uname({sysname="Linux", nodename="xubuntu", ...}) = 0

BUT when using the persistent storage on the real filesystem (but SAME exact permissions) it fails:

newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3", {st_mode=S_IFDIR|0775, st_size=4096, ...}, 0) = 0 newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=1519466008}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = -1 EACCES (Permission denied) close(11) = 0

Am I doing anything wrong or is this some weird startup issue / race condition in the parentlock management?

Thank you for looking into this.

PS: I can upload the full strace file for both scenarios if needed. Thanks again.

Starting recently the firefox popups for website notifications are stealing focus and disturbing my workflow. I'm using i3 window manager and normally popups would have some id or class that can be used to latch on and prevent the focus stealing but the windows created now do not have any such marker.

Hello, Firefox keeps crashing every 1 or 2 minutes. thats a new Endeavouros installation and firefox was pre-installed. system is fully updated.

would you please assist troubleshooting the issue

Reopening https://support.mozilla.org/en-US/questions/1412054

As you can see from https://github.com/linuxmint/linuxmint/issues/577 this issue is caused by Mozilla not caused by Linux Mint as accused in questions/1412054

Can you be honest and address this?

The video from most websites plays out of sequence. It appears that approximately every one second plays its frames in reverse order. This occurs with most video streaming services and major sites. For example, all Amazon, Sam's Club, Walmart and other website product videos. Occasionally, Amazon product videos just say not compatible. However, YouTube videos with very rare excepts play fine in Firefox. Those problem sites play the videos fine under Edge for Linux. But, I would much rather use Firefox. I'm sure this a codec related issue. Possibly related to the NVIDIA GeForce GT 1030 video card in this computer running openSUSE 15.5. But after much searching, I'm at a loss on how to resolve the problem.

I'm running firefox 124.0.2 on Linux Mint and am having the most bizarre issue. I've got a logitech M560 mouse, and when I press the mouse button for Forward it functions normally. However when I press the mouse button for Back, Firefox ignores it.

I've already confirmed that the OS is registering the button click as 'Back' using Input-Remapper, and the extra mouse buttons are enabled in the Firefox configuration. I've also used the mouse on another PC with no issues so this one is kind of boggling the mind.

Hi! I do not want more cookies than "necessary". So I reject, make settings etc. And I clean them automatically when closing Firefox, just in case. On some sites that I visit very often, this turns out very tedious and timeconsuming. How to allow only necessary cookies and not the rest? With Privacy & Security, Cookies and Site Data, Manage Exceptions, I can allow or block cookies from specific sites. What do I allow when I choose Allow? Only the ticked ones or all marketing and other stuff even when these are not preticked as default? Or will the choices made during this session be saved? In the case of my bank and a couple of others, I would like to save my choices to be able to enter it a little faster. But cleaning at closing Firefox also deletes that, I suppose? How to save my choices without saving all cookies?

Is there any way to see what kind of cookies have been saved? I can see the number of cookies for each site under Manage Data, but how to see the type of cookie?

I have some new issues after a recent update.

The tab bar fades when the window isn't focused. I certainly didn't have it set to do that before, and I have had no luck finding the setting for it. Tell me what the setting is?

Another I'd like to know the setting for, is the behavior of the address bar. It used to always be white, and now it's gray unless I'd entering something in it. I'd like to switch the setting back to the other way.

I've tried hunting for the settings for these things, but it has not been intuitive for me, and I guess I keep overlooking the pertinent settings somehow. Please tell me what parts of the settings page, or what about:config entries, will get things put back as I had them?

Hello there. I'm used to pressing Super(Win key) + Grave(`) to type "`" because the Grave key itself is a global shortcut for opening the terminal window. It works as expected in the other applications, but not in Firefox input fields. If the site is capturing the key presses, it will handle the super + key as usual. For example, GitHub will surround the selected word with ` symbols on grave key press. This problem is not limited to super + grave, but any other letter. For example, Super + q is expected to produce the letter "q", but in Firefox it produces nothing.

I'm trying to identify why the Super + key behavior in Firefox is different from other systems and if I should open a bug or not. Maybe this is the same bug as https://bugzilla.mozilla.org/show_bug.cgi?id=1626609. Thunderbird has the same problem.
