This happens at random intervals, mostly when firefox is being left idle.

Since it starts >1000 threads, it easily fills ram and swap, then get killed by OOM killer. Hence no crash reports.

I'll upload a gist with OOM details from dmesg and journalctl, if there is a way to get debug info for this, please let me know.

I have a problem with Firefox not maintaining granted permissions which forces having to re-grant them, re-authorize/signin etc each time (several times a day). The problem exist on several sites (I think they're related, please correct me if not). eg google workspace suite; I'm using gmail in browser, with Calendar, Drive, Voice, and other elements. Having logged in to gmail (which always forces 2fa even though I check "remember this device"), using the other functions of workspace should be authorized, but if I go to say a folder in Drive, or try to create a Calendar event from an email, a new tab opens and I'm forced to sign-in again (with 2fa). All the google addresses I use are in the "allowed" section of Firefox settings, their cookies saved as exceptions for filtering and saved on exit, and allowed in cross-site filtering. I can't think of anything else to do that would prevent having to sign-in all the time. Similarly with other secure sites such as financial institutions, despite having them bookmarked, cookies allowed, checking "remember this site" etc, every instance has to be re-authorized, re-signed in with 2Fa etc. I only ever use the same laptop and smart phone so it doesn't make sense that neither of these devices are ever recognized. I even get email notifications "detected a new signin on an unknown device" etc. and this happens across sessions, before hibernation or shutdown. How do I get premissions to persist?

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

After installing version 118, Firefox does not automatically explain the pages.I have to go out in the settings and choose the language of the translation every time. The problem occurs after the browser is synchronized. MX Linux system.

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

There is no gear icon when I open a new tab. and my thumbnails are missing. Tried the solution here Right clicking does not give the option to restore defaults. value of browser.newtabpage.enabled is true. changing it to false did not change anything, neither did changing it back again.

I want Firefox on my action (button press or keyboard shortcut) run shell script or program of my choice and giving it as parameter the url of the actual web page I'm seeing.

Is it even possible?

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

I'd really like Firefox to use my X selection buffer, or, if that's not possible then stop supporting shift+insert because the inconsistency is jarring.

In a terminal I highlight then use shift+insert to paste, but when use shift+insert in Firefox it pastes my copy buffer rather than my selection buffer. So I copy something from the web, then use shift+insert in my terminal because I'm used to that now, and I paste the wrong thing in. And I highlight something in my terminal, switch to Firefox and use shift+insert to paste it, and it pastes the last thing I ctrl+c'd.

If shift+insert did nothing in Firefox then I'd get used to it, but the switching back and forth is something I stub my toe on every day. Does nobody else feel this pain? Please fix it!

For the past few days, the YouTube website has behaving unusually in Firefox. The volume and play/pause controls don't work. The picture in picture mode does not work. And most importantly, the search bar is broken. Whenever I type something and click the search button or press enter, the value entered disappears and I have to type it all again, only that this process goes on for infinite number of times and so, I can't even search for anything on YouTube.

Hi,

I'm on Arch Linux and use uinput to create key events. It works reliably for >12months in all applications and under all circumstances except in Firefox where some key events are skipped non-deterministically. My test case is:

in a text field, emit `<ctrl down>a<ctrl up>123456789987654321<left>...<left>` with 9 times `<left>`. Sometimes a 9 is missing and sometimes the cursor is further to the right than expected.

This happens every 8th try or so, which is too frequent to not break the user experience.

What I have tried: - multiple PCs (2 with this issue and 1 without) - Troubleshoot Mode - `window.onkeydown=(e)=>console.log(e)` (events are missing)

Since I've only ever seen repeated characters/keys disappear and never when writing manually, I would guess there is some kind of event cleanup algorithm kicking in. (the events are emitted without any delays)

I would really like to fix this issue because Firefox is my favorite browser. Any idea how to track it down?

using ver 117.0.1 on LinuxMint 21.2 all website and search engines work well, only can't use DuckDuckGo, get error message: "Firefox has detected that the server is redirecting the request for this address in a way that will never complete

Please help

Firefox used to have an option to put tabs back under the address bar, it is missing. I don't want to mess with custom css files every update when mozilla breaks things again.

Very recently, I was typing a ton of content into a website textarea, when my Firefox Nightly install crashed. I lost all of this work from hours. Is there any way to get access to this data?

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!
