I don't remember with which version of Firefox for Linux this issue started; but I cannot play multiple videos at once. If I open two tabs with video sources one of the videos will automatically pause if I start watching the second one.

I have tried disabling my add-ons but the issue persists and I don't think there should be any reason for any of them interfering with videos.

Currently running Firefox 120.0 (64-bit - Arch Linux)

Hi, I have a weird problem, I have 3 systems on my device: windows(10), ubuntu and Arch lately when i was configuring Firefox on fresh arch install I was annoyed that I needed to re-login to every single s...t again. So I thought "Why can I just share the same FF profile between systems" Long story short it didn't work on Arch. I was forced to compile FF from source and now it works... but when I'm logged in on Ubuntu and trying to launch FF from GNU I always see this error. it's working when i point out to profile from the command line with "-p <dir>". but even then when I go to about:profiles and click "launch in new browser" it's still pooping with this error. So Am I doing something wrong or it is just impossible to do this seamlessly? is there a better(correct?) way to achieve the same functionality?

thanks for reading, ill humbly take any advice.

EDIT: I have copied the profile's folder to a separate partition which is auto mounted tried it on Ubuntu (at this time it had been working just fine) and after using it on Arch when I was back on Ubuntu it was displaying this error

I'm having the exact same problem as what was originally mentioned in this post from 4 years ago.

The "chosen solution" was to exit firefox through the hamburger menu, which I find to be absolutely ridiculous. You mean to tell me that even though I close EVERY OTHER APPLICATION either using the "X" close button or a custom keybinding that I've set for my own personal convenience, firefox requires me to exit through a menu every time in order to make it behave the way I've told it to? No. Absolutely not. If I tell firefox that I don't want it to save my last session, that means I DON'T WANT IT TO SAVE MY LAST SESSION. If I've deselected the "open previous windows and tabs" option in the settings, then under no circumstances should it be trying to open my previous windows and tabs.

I've tried the suggestion to change the value of browser.sessionstore.max_resumed_crashes from 1 to 0. The problem persists, I assume because firefox considers being closed using the close button to be a "crash", which is interesting.

I the other suggestion further down in the thread was to set browser.sessionstore.resume_from_crash from true to false, which will prevent firefox from recovering a session from a crash. This is hardly an appropriate solution. I want firefox to resume my last session if there is a legitimate (key word LEGITIMATE) crash, because my session was closed against my will due to something that went wrong. Being able to recover my last session in such a situation is nice. I do not, however, want firefox to resume my last session when I explicitly closed the last session myself, which would be the difference between a crash recovery and restoring a previous session. If no crash occurred, I don't need a crash recovery, and aside from a crash, I don't want my previous session to be restored.

Are there any solutions to this at all? Because this is one of the biggest reasons why I stopped using firefox. I want to come back to firefox because everything else that's worth using is either dog shit, or Chromium-based (i.e. also dog shit). However, I find this broken feature to be somewhat of a security issue. If a bad actor somehow gains access to my system, I don't want him to be able to open firefox and have access to my last browser session because I closed firefox using a keyboard shortcut instead of closing it through a goddamned menu.

Firefox has crashed repeatedly when I've switched tabs to my gmail in the past ~15 minutes. It happens in "troubleshooting mode" as well. I'm running firefox on a linux computer, and my ubuntu installation and firefox are both up to date.

Here's my crash id: bp-b079d597-fb83-4a69-ab65-896370231129

OS: Ubuntu 23.10 Firefox version: 119.0 Mozilla Firefox Snap for Ubuntu

I have DNS over HTTPS enabled and set to Default Protection in Firefox.

According to the following article (https://support.mozilla.org/en-US/kb/dns-over-https?as=u&utm_source=inproduct#w_why-would-a-network-tell-firefox-not-to-use-secure-dns) DNS over HTTPS should automatically switch to "Not Active" when connected to a VPN.

I am using the NordVPN CLI for linux and have found that when I connect to the VPN, Firefox DNS over HTTPS stays active and does not switch to "Not Active" like it is supposed to.

Does anyone know why this might be happening?

I have an issue with the address bar in private windows. Normally when you click on the search bar in the new tab page, it will redirect the cursor to the address bar instead of letting you use the search bar.

I found the following solution on the forum here that works for normal windows: go to the about:config page and set browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false.

For private windows, this fix does not work. It will still go to the address bar instead of letting you use the search bar. Is there another way for me to fix this so that it will also work in private windows?

The new selection "Copy without site tracking" may eliminate certain codes, but does not remove all invasive data (my term). Consider this common URL occurrence:

link text

The new filter does absolutely nothing to this and when I pass this kind of URL on to others, I do not want to include all that crapola. Currently I have to manually edit the link, which can really get tiresome when passing on a lot of links.

Is there a way to modify anything in Firefox to accommodate this?

I am suddenly getting the following error message: "We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser)." Firefox is now unusable. I have searched "Settings" and can find nothing about "Content Filtering," "Shields," or "Brave Browser." Can you tell me what is going on here?

When watching videos on YouTube or Amazon Prime, Firefox will eventually stop recognizing keyboard and mouse input in all windows and tabs. This can happen after just a few minutes of video or after hours. It affects nearly all input: typing or clicking in webpages, the toolbar, the address bar, etc., though I can click the 'x' button to close tabs. When I close the final window, a dialogue will appear stating that Firefox is non-responsive and allowing me to kill the process. This seems unusual, because the OS's system monitor indicates there is plenty of unused and available RAM and CPU resources. Firefox behaves normally after restarting.

OS: Xubuntu 22.04 Firefox version: 120.0 (though previous versions have been affected for the last few months)

Is there a way to use the default xfce windows instead of firefox`s own? I mean I have my own setting in the xfce window manager that are not applyed to firefox. fo example: I unchecked Raise windows when clicking inside application window, that is not applyed to firefox, I also have a context menu when right clicking on other windows title bars that I can customize, In firefox I have something total else.

I use a lot of keyword search engines. This means I can type something like `kagi foobar` to search Kagi for `foobar`. However the awesome bar has a "feature" where if you type a question mark (?) anywhere it instead uses the default search engine. This means that `kagi How do I cook a turkey?` searches my default search engine for "kagi How do I cook a turkey?" rather than searching Kagi (based on the `kagi` keyword). Is there a way to disable this behaviour?

I have searched about:config and "Search Shortcuts" in preferences doesn't have a `?`. I never use `?` as a shortcut to search (I just type the keyword for the engine I want) so completely removing it would be perfect.

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

Hi,

This is for https://outlook.live.com where I cannot access my full list of folders. I am using Firefox on Linux (in Fedora 34) and my scrolling feature hasn't been working for a few days now. When I search for an email in one of the inaccessible folders, the folder does appear.

As an idea... I added https://outlook.live.com to the pop-up exemptions, no luck.

Any suggestions on how to fix this?

Many thanks!

I really didn't want to make an account and synchronise.... I only use the passwords on this machine. But I do need to view them all in.

So, set that all up, synchronised...even rebooted. But still can not see my passwords? I'm logged into several sites...auto logged in every time. Just that I have forgotten what some of them are....Firefox knows? But still won't let me see or download them.

I also can't seem to find my logins.json file...but it must be somewhere as firefox has remembered all the passwords!

says 'No synchronised logins found.'

I'm also on linux here if that matters. Seems to be a bug or i'm not doing that I do need to do?

I am using the latest version of Firefox on Linux Mint. I've had some flash on opening issues that I've been unable to permanently prevent. Suddenly my adblock software is not working. I tried uninstalling, reinstalling, different adblocks-no improvement. No extension software is showing on my toolbar and selecting the extensions software just brings up a suggested extensions.

i installed updated version of mozilla and after login i lost all the previous data and i also tried it to recover from my last backup but it's not working please help me with that i need my data back

On the new tab, the box around the shortcuts and the search bar stay dark grey. I've messed around with all the advanced color options on firefox color, but nothing seems to affect it. It bothers me since I changed the background color.

It seems that this problem is common in firefox community. So first of all I basically tried all default troubleshooting steps such as dealing with cookies (turning off, tuning on, exceptions), cleaning data, cleaning cache, security settings, etc etc, even though I am on freshly installed firefox.

So lets see now, problem is with https://vk.com/ website. It works until processing my login info. After I enter necessary credentials, it reloads and just produces infamous error. Network monitor displays loop of login.vk.com domain migrating cookies to login.vk.ru which restores them and then finally trying to open actual account php page starts the loop anew. Well until NS_ERROR_REDIRECT_LOOP stops this shamelessness. Resetting all browser data back, just enables me to enter my credentials again and the same process starts again. I can access this website from the same network from different browsers from different devices and operating systems.

Currently I encounter this problem on recently installed Arch linux, with basically dwm and firefox, and since I had very rough time with how unpredictable this system were so far, I don't know how much it is browser issue, so I think I should mention it.

Thank you in advance.

The videos on YouTube work, but when I go to other pages I get this message, I already tried removing all the add-ons, the hardware acceleration, even doing a 0 installation and it still gives me the problem, and also in others devices with fedora, I get the same error.
