Hi all,

After the last update the former Mozilla Test Pilot "Snooze Tabs" isn't working for me any more, I tell a tab to snooze and it just stays where it is. https://addons.mozilla.org/en-GB/firefox/addon/snoozetabs/

I've tried running with addons disabled and then running with addons active again and the behaviour is the same. It's the same behaviour whether I run from the toolbar or the context menu.

I'm presuming this problem is related to Firefox update mechanics. Any suggestions for how to get this working again please?

Cheers :)

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

Hello brothers and sisters, i am need help! I'm experiencing performance issues when surfing the 9GAG website. The amount of RAM consumed by this page is growing exponentially. It's gotten to the point where this tab can consume up to 5GB of memory, and that's not the limit. This issue hasn't happened before. I can't figure out what's causing it.

What I did to fix the problem: I reinstalled the browser. I reinstalled add-ons. I reset my old profile, saving only bookmarks and passwords. I reinstalled the operating system. None of this helped. However, my friends don't have this problem with this site. Please help.

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

When I search for something it shows up in English, but some text under the result is French as shown in the picture. I use latest Firefox with Google search engine, and I have all settings in Google set to English, And same for Firefox settings

Hello, I've been watching MSNOW at 4pm eastern and after about half an hour it crashes. I get a message to send a report and restore the tab. I restore the tab which works for maybe ten minutes and crashes again. I am using Windows 11 on a new computer. I'd appreciate some assistance. Thanks. Bruce Caress

Moderator note: This question has been edited to precise Firefox and OS version, based on the crash reports.

I can access Chewy with Safari, but not with Firefox. So the problem is not with my Mac settings and the problem is not with Chewy, the problem is with Firefox. Please address and fix it.

I can't log into chase.com from Firefox, which I've been doing for years. I get an outage message. But down detector shows nothing. It went on for days so I tried Microsoft Edge with Bing and it works. Is there some Firefox setting I need to change?

FF for Linux Mint mint-001 1.0 FF closes in just a couple of minutes, even with one open tab and nothing clicked or typed. FF crashes even in "Troublshooting Mode". "about.crashes" lists no crash reports Using Task Monitor to view system vitals, I discovered that while CPU usage by FF is very low, memory usage rises linearly over a couple of minutes. System memory available is 31.0 Gb. When FF usage reaches 30.7 Gb, FF crashes. No other browser or program has issues.

I use multiple Firefox profiles and create separate desktop shortcuts for each profile using Firefox’s built-in profile shortcut option. I then pin each profile shortcut to the Windows taskbar so I can launch them independently.

The issue is that when I click one of the pinned profile icons, Firefox opens a new separate taskbar group/icon instead of attaching the window to the already pinned taskbar item for that specific profile.

For example:

• I pin Profile A and Profile B separately to the taskbar.
• When Profile A is already open and I click its pinned icon again, Windows creates another Firefox taskbar button/group instead of reusing the existing pinned Profile A button.
• Google Chrome profiles do not behave this way on Windows — each profile stays grouped with its own pinned taskbar icon as expected.

Is this a known limitation/bug with Firefox profiles on Windows taskbar integration, or is there a way to make Firefox profile shortcuts behave like Chrome profile shortcuts?

There was an update with Mozilla Firefox on the 8th. I had tabs open on the computer. After the update, I could not retrieve the tabs I had open. Tried to restore and nothing worked. Is there any way to restore my tabs?

I'm sure it's a setting but I can't figure out which one.

It has always logged me out when I close or update the browser, which is a minor inconvenience. And in that instance when I got to log in, it has indicated that a verification email has been sent to my account, and historically clicking that does the trick.

Now it does one of two things: It will either tell me to click on the verification email sent to my email account but the verification email it never arrives, or it will simply remain static, as if I never entered a password at all.

Very frustrating, please tell me which settings to change and I'll do it. Thanks!

I have a new mac, an M4 mini, and I set up Firefox the way I want it (the biggest ask has always been getting a bookmark to open in a new tab). Two days in, sometimes a bookmark opens in a new tab, and sometimes it doesn't. I have nothing else set up except for an ad blocker. I have not changed my OS from Sequoia to Tahoe yet, I strategically delay. It's not the end of the world. But I had strange things happen with Firefox on my other mini (an M2) in the last 6 months and I had to abandon Firefox and use Safari, which I hate. But that's a whole other topic. I've used Firefox forever, and it's my fave, and little things like this bug me. What am I missing? I set the option to False, and then reset it to True, and sometimes it works as it's supposed to, and sometimes it doesn't. So to not overwrite an open tab that has something important, I just automatically click on the 'command' key when selecting the bookmark. It's staying on my selection to 'true' and I've set it to false and then set it back to true, and restart Firefox, and I still get inconsistent results. There's nothing else that could be conflicting with this. I don't get it. Like I say, Firefox on my other mini just totally became unreliable and I had to use Safari. Any ideas? Thanks!

How to sort Tab Groups alphabetically in the Add Tab to Group Menu?

I want to add tabs to groups bit the groups are changing their position and it would be very helpful to (optionally) have the freedom to sort Tab Groups to appear alphabetically in that menu!

But that should NOT affect the sorting order in the browser window!

But of course it also would be helpful to have the freedom to also sort the tab groups order in the main windows, but please make it a different sort order than in the Add to Tab Group menu dropdown.

Thanks!

Whenever i send a Tab from any Device to a Linux Desktop, the Linux Desktop is almost guaranteed to freeze. It doesn’t matter if that Linux Desktop is my "Dingus" PC with 2GB RAM and Wayland, or my "Workstation" PC with 16GB RAM and X11. On both Desktops, Firefox runs smoothly until it gets sent a Tab from another Device, then the whole Linux Desktop freezes. The Desktop doesn’t slow if i open the Tab on the Desktop in the “Tabs from other Devices” Sidebar instead.

Only my Linux Desktops freeze when they get sent a Tab from another Device. Android doesn’t slow when my Phone gets sent a Tab from another Device.
