Firefox Community Forum

I use Firefox for viewing my Rogers/Yahoo web mail in an open tab. I have granted Yahoo mail permission to send notifications and I get a Windows 11 toast notifications when there is a new email in my inbox.

The problem that I cannot figure out is that the notifications take the form of "X undefined", where X is the sender's name. There is something that is appending the word undefined to the sender's name in the notification. I also note that these notifications are "sticky", that is, they remain visible until dismissed. I would prefer that they dismiss after a few seconds and remain in the notification centre.

I am using Windows 11 Home edition with the latest updates.

Whenever I open Firefox in my laptop, many pop up news snippets start appearing. It disturbs me and intrudes into my work. Please stop all pop ups and notifications. Thank you.

I tried reinstalling firefox because I wasn't getting notifications from websites. I'm not getting notifications now either. I checked my computer settings and reinstalled the software on my Mac Book Pro 2012 version 10.15.8.

Hello, My brother clicked on "I am not a robot" popup after he clicked on an image to enlarge it on a website and then click on "allow" permission to send notification. So now there are always 3 notifications (like warning, viruses found, system alert, etc.) on the screen that will pop back on right after I close one. This is pretty annoying. I went to the firefox settings, in "privacy & security", scrolled down to "permissions" and "notifications" section, changed the status of that website from "allow" to "block", and then (and it may be my fault here, but how could I know ?) clicked on "remove website" just below. Well, now the website is not there anymore, but I am still getting annoying warnings notification that can't be close. We can see the adress (don't know if I can write it up here, but you can see in the photos attached) on the notifications, so I opened up a new tab and wrote it down manually to be able to click on "block" directly, but I am just getting a white page (no window to click "I am not a robot" and no window to ask to allow notifications). I clicked on the little shield icon that is at the left to the address bar and then clicked on "clear cookies and site data", but it did not change anything. I am at loss here. I went back to the website with the image on it that my brother clicked to enlarge, and I clicked this image too. The same thing happened (robot, allowing notification popups), but the address is different (you know when it's a long non sense address... always almost the same but with some different letters/numbers) . So I can block this one, but not the one that is still allowed somehow to send me notifications. I closed firefox then restarted it, no change. Any ideas ? (Sorry the photos are not straight, don't know why because I can see them just fine upon opening)

Hi, I'm on Linux mint and I can't stop google calendar notifications from stealing focus from other windows. E.g. I can be typing in VSCode with firefox open in another window, and if a calendar notification triggers I'm suddenly typing in whatever tab I have open on firefox.

I've tried disabling notifications for the site, following [post] (though I don't have a padlock in my address bar, I just went to the settings manually), everything Claude can come up with on both the firefox and os level, etc. and nothing has worked.

I need the notifications to still be enabled at the calendar level (so that other devices have them), and I like having notifications in general, just the focus stealing is a dealbreaker so if I need to get rid of them on this device to end that then I'm okay with that. But really I just want to stop the focus stealing.

Any help would be much appreciated, thanks!

I get scam messages that say "Trojan virus detected!" on Mozilla Firefox which I cannot delete. I have run antivirus scans which show there is no virus or malware. I have shut down the desk top. How can I go to reinstall Mozilla Firefox default settings or do you have another solution?

I'm using an out of date Windows 10 laptop. I am aware of the Windows 10/11 thing. I know. I've got my own reasons for not updating this one, it's not my only device. I get it. I understand. I know. My settings are how they are on purpose. I do not need to be nagged in this fashion.

How do I turn this off? I can't find it in settings. It's not appearing on any of my other browsers. It's just Firefox. Please help, it's driving me crazy.

Thanks in advance.

Hello: FF dev 150b5,w11p. With this v 150 there's a new irritant that I would like to stop, please. That's the sudden (starting w/v150 again) appearance on lower L corner, of a popup window, which may be interactive. That is, this thing is so new I can't say more about it except that I didn't change anything to make this thing appear, & this didn't happen in prev.versions.

I looked in settings & the only thing on keyword "popup" goes to, in "search results", is: "block popups & 3rd party redirects." I already had that choice checked from previous versions (that is, do block). But this new popup appeared (unasked) anyway.

Is there an extension that will stop these? If so, what keyword(s) do I put into the "search extensions" box to find the extension(s)?

Also, w/this new "wonder" of unasked-for popups -- is this another "coming w/AI" feature I will have to live with?

I did a search here on "popups" before posting,but came up w/nothing relevant.

Thank you.

Bonjour Je suis "harcelé" par des notifications (cf fichier joint) qui m'annonce, un virus detecté, un cheval de Troie, une alerte système, une erreur critique... en m'indiquant toujours via d75ag1anaffc73bd3jj0.jhec-defender.pro J'ai beau cliquer, je n'obtiens rien sauf assez souvent une connexion à Avast (qui n'est pas installé sur ma machine !) et qui me détecte aussitôt de 3 à 5 virus... mais qui ne être supprimé que par une version payante d'Avast Réelle menace ou publicité agressive ? Comment se débarrasser de cela sans bloquer toutes les notifications de Windows Defender ? Cordialement

Is there a setting to disable product update notifications?

For example, I got a notification on Windows today prompting me to try out Firefox's new split tab view.

I do not want to receive these product update notifications.

I know I can disable notifications in Windows at the OS level, however, this also disables notifications for all websites I have enabled.

Is there an option to disable these?

I've recently begin to receive pop-up notifications from Facebook, but when I choose to stop them, it doesn't. It takes me to Facebook and the notifications keep coming. How do I stop them?

I am seeing pop up ads like these on the lower right corner of my screen since I updated to windows 11. I've never seen this with windows 10. Microsoft is telling me these are coming through my browser. These are not when I am in a web site and get the pop up to allow notifications, I always say no. These come @ 1 per week or less and I don't seem to be able to stop them. Is there a setting in firefox that will stop them or is this a microsoft issue? thanks brian

I have notification that someone charged to my apple account. Sure it’s a scam but I cannot delete it from Firefox app. I’ve shut phone down and closed the app but it still is on my phone

I keep getting messages from the Sun Sentinel through Mozilla-Firefox and I don't want them.

How do I stop them?

I went to the security tab and see the list of exceptions and the Sun-sentinel.com website does not exist.
