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, 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.

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.

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.

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.

Why has  << teaseyourmatch.com >> opened its webpage yesterday & for several months while; today it won't load the homepage whatsover? This is an adult dating website from Eurozone w over 125000 users

All the tabs, in both my profiles are constantly crashing. I cannot keep at a task for more than a few minutes without needing to restart the tab. Is this a setting problem? I've cleared the cache, and reset Firefox, to no avail. Thank you for any relevant advice and/or assistance.

So every few days now if the free VPN is on I get my tabs locked into an error. I get that warning screen and sites stop loading or partly load, before the VPN update I never had to close Firefox this often, if left idle with the VPN on this seems to happen faster, I have left the VPN on overnight and I tend to nearly 90% of the time wake up to this error, if I disable the VPN fully I can pick up where I was but cutting it back on I have high odds that it will break, Firefox is idle while I do other stuff and the VPN is on, I get that error and I get to watch the weather app give me it's error. I have never had Firefox fight my antivirus It worked fine for ages, and only now do I need to reset Firefox by force now every 1 to 3 days. I use to be able to leave tabs open, but now they always error out in a few days. It could be other things, I just never had problems like this until now, it's so common and in the same time tables.

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?

I use the current version of Firefox on Ubuntu 22.04 Linux. When I scroll down past the individual bookmarks at the end of the menu, the folder names start repeating, along with the bookmarks inside them. I have three or four sets of bookmarks and would like to have only one. How can I delete all the bookmark folders below a certain point? By the way, when I install a new, different version of the operating system and sign in Sync restores all the bookmarks.

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 was getting popping in audio both in Smplayer & videos on other sites. I discovered the problem went away completely when I closed the X tab. When it was open, I noticed another glitch. I keep a small video windows to keep track of my sleep time. The elapsed time is displayed on them. Only when X was open it was throwing it off by about 3 seconds a minute. I closed it in Firefox & signed onto X on Chrome & all these problems went away. This is the only web site that has ever done anything like this. What is Firefox's problem with X?

When I click on option/link for "Print using the system dialog box", the print preview no longer works. Instead I see message "This app doesn't support print preview" in preview pane.

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?

Hi,

I shared a lot of important tabs to my laptop (using the firefox built-in share/send to other device button), upon starting it, they seemed to arrive just fine and opened on my laptop, however I accidentally clicked to "history"->"restore last session", which made this firefox window go away and all my sent tabs seem lost.

Is there any way to get them back? Any type of log?

I tried the following already: - Looking through History (they do not appear there at all) - Looking at recently closed tabs (there aren't any listed) - checking synced tabs window (did not contain the ones I sent from my phone to my laptop) - checked session recovery files ( none of my synced tabs seem to have gotten stored into that session recovery file)

So is there any other log or place I can look at? I refuse to believe that this is not saved anywhere? Or on mozilla servers at least? Can support help me?

Thanks for any ideas!
