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

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Hi all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

Thanks, penguinoid

(*) I'm using a university owned/managed computer and they've disabled the option to update to Windows 11

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

Dear FF/Mozilla:

I've experienced a number of issues where I'm unable to do banking transactions using the FF browser. In one case, Wells Fargo bill pay does not work (but works fine with MS Edge); in another case, an international money link payment to a vendor in the UK would not go through using Firefox (but did first time with MS Edge). In yet another case, Firefox won't load webpage photos for items for sale on the site www.telescope.com - the page loads with descriptions but photos would not load (I just tried it and, nada). This remains the case even after my VPN is disconnected.

I've used FF for several years now without too much trouble but with this ongoing non-functionality of FF, I'm tempted to migrate to MS Edge or a browser that is supported more widely.

Any help or advice? Thanks, Blaine

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

Hello, Under about:preferences I went to applications. Under mailto there were references to Yahoo and Gmail which I deleted. Now then when I click on an email address link on a webpage the mailto menu pops up like it always has but Yahoo and Gmail are no longer listed as email options. How do I get those links back? Firefox is listed as the default option but because there are no links to webmail services there is no way to send an email from that menu. Sincerely, MKH

On spotify web player in firefox there is a delay after skipping 15 seconds forward or backward in audio. Only on bluetooth speakers. But doesn't happen on Chrome. Anyone got a fix or can help?

I have a problem on YouTube where videos are too bright, but when i click for example to save that video to watch later it has normally saturated colors. And I'm using windows. On photo example1 video is too bright, but on example2 it is normal. thanks for help

Hello,

Like I suppose any user of older systems (Macs...) that cannot be updated to a newer OS version and thus locked-in to an older Firefox browser I received an email today:

"Don’t stop the sync. Upgrade your Firefox before March 31st."

Why, why, why??

Why would Mozilla take away this last little bit of usefulness after already having abandoned all updates to the browser itself? Why actively "fix" something that ain't broke in a why that does actually break it?

And don't give me the sacrosanctuous security argument please ;) - I never synced sensitive information, not even my browsing history. If security *is* the reason it should be hardly more difficult to disable/disallow just the syncing of that information at the server end. We're clearly speaking at a change on that end anyway, otherwise everyone NOT running the very latest version would be urged to update, not just users of v78 and older.

Anyway, I'm sadly aware of the fact this little rant or even a concerted action isn't likely to change anything, so what options are there? Any suggestions for browser extensions that provide syncing of bookmarks and maybe open tabs or even browser preferences?

Thanks!

PS: I'm posting this from another older system currently still running a Ubuntu 14.04 version that is in fact hardly younger than my Mac's OS but still enjoys Firefox updates...

Hello, I always use Firefox logged into my Mozilla account.

Yesterday I went to a (legitimate) site, that I had never visited before and only read one page. I didn't click on anything on that site/page, I only read that one page and left the site. Not long afterwards, I received a promotional email from that site stating "Thanks for stopping by!".

My question is: how did they know my email (the email used by my Mozilla account)? I have never received emails from that site, and as I said, I never visited it until then.

Does Firefox expose the Mozilla account email when visiting sites? This is pretty troubling. I would appreciate any input you have. Thanks

I am trying to zoom in and out on a webpage JUST the elements. I DO NOT want the text to zoom in or out when I do this. I was able to do this within the last couple of days here, but cannot remember How I did so..

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

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)

I'm a cybersecurity professional and I'm researching about Same Origin Policy, Cross Origin Resource Sharing and how firefox deal with those things. I've find out that versions before 102.1.0esr, cross-origin script GET requests used to attach cookies (Image 1), but in newer versions, it's not happening (Image 2). I checked the release notes but didn't find nothing about this change.

I would like to learn more about what changed and how Firefox is dealing with cookies, SOP and CORS.

Thanks!
