Firefox Community Forum

I've checked a couple of the "similar topics" before posting here. I'm not sure if I am having the same problem or something else.

Back Story: I have a "few" windows and tabs open in FireFox. I would finish what I was doing, shut down and then the next time I booted up and loaded FireFox, all sessions would be restored and all log ins honoured (kept). That is: I was still logged in.

(Moving to now) Yesterday I powered up and ALL sites were logged out. About 20 log ins were needed. Hmmmmm... gmail, and the rest.

"Ok... something happened. No problems, things should be ok from now. I've logged in, so all is sweet."

Today I power up: All logs ins lost. Had to go through it all again.

Gmail is throwing security alerts at me hand over fist. Yeah, that is good in some ways. I get that part. But I've logged in.

Seems - my thoughts - that the cookies aren't being saved. But why? I haven't touched them or their settings.

Yes, I did do a clean out of older cookies. But left the gmail ones, and other sites I know I use. I have `adblocker ultimate` installed.

Now I am logged in, if I open the `cookies` and look I should see them there for the sites to which I am logged in - yes?

To be clear: When I am done, I do NOT `exit` FireFox. All windows, tabs, sessions are left. I just shut down the machine. Then next time I load FireFox and they are re-loaded and log ins are maintained.

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Exported a bookmarks html file from Mac (Sonoma OS) and tried to import it in a computer running Zorin (linux) 17. The file can be found, but when I click it, I am told there are no bookmarks therein. If I open the HTML file it's all there. Full of bookmarks. What am I doing wrong? Thanks for reading.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

here

I am using a Samsung Chromebook Pro V2, running Debian, and installed Firefox using the Flatpak command "flatpak install flathub org.mozilla.firefox". The Firefox icon appears in the Linux apps group and I have opened Firefox using that icon.

How do I get links in my Linux apps to open Firefox and take me to the URL?

Thank you and Happy New Year, Abe

I have a new installation of Ubuntu 22.04 on my 2015 Lenovo IdeaPad 300. I have a new SSD HD 1 TB in size and it should work, however, Firefox keeps crashing. Other apps are crashing too.

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I​ hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

​I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

When I open `about:preferences` tab, `Downloads` directory is created in my home directory, despite my downloads directory is different. I've read issue 474718 which states that it was fix but i still experience it. Linux x86_64

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

Hi all, I use to update Firefox with my Linux distribution package: I build the new package then upgrade it on the system. Anytime at the first launch of the new Firefox just installed version, it opens a new blank profile instead of my usual profile. I can set my usual profile as default by launch Firefox Profile Manager. So after update I launch from command line terminal or through launcher bar:

firefox -p

And It starts up profile manager, then I choose my usual profile and check it as default one. After that, when I open Firefox again, it uses my usual profile as expected.

Now the question: - is there a way to automate this procedure so I have not to repeat it anytime after I update the browser?

PS. I noticed my "profiles.ini" file is populated with a lot of profiles sections, likely maybe anytime I update, a new one is added in here. I don't know if it is a regular behavior or not.
