Firefox Community Forum

I have been able to use the builtin VPN for a couple of months now. In the past week, when I try to turn on the VPN, I receive a message that I am not connected to the internet, even though I already am.

What is the issue?

Since yesterday, videos on NetMirror are not playing. Every video shows a “Video load failed” error. I have tried multiple times, but the problem is still happening. Please help me fix this issue.

Setting up a new Macbook air m5 and trying to sync my profile/bookmarks/etc. on FireFox but the confirmation code is not arriving at my gmail. Checked spam and added "accounts@firefox.com" to my contacts but still not arriving. Help?

I received an error indicating that Firefox was unable to be updated. I tried refreshing the installation as suggested, to no avail. Then I removed the application, downloaded the most recent version, and tried to install it. The installation never seemed to begin. I tried troubleshooting compatibility again with no success.

I've rebooted between each failed attempt to install (at least twice). I opened Task Manager, and the process appears to be stalled. It starts; however, it doesn't consume any resources and hangs. I've attached a screenshot of basic system information.

I use Firefox as my default browser; I would really like to get the newest version installed on this device. Thank you, Aluca Lindstrom

I've noticed that Mozilla products (firefox, thunderbird etc) all phone home all the time, which is a violation of both my security as well as privacy policy. In the firewall one can observe persistent, periodic, repeated connections to various non-sanctioned sites and services, apparently run by Mozilla. These include, but are not limited to:

• .mozgcp.net
• .services.mozilla.net

firefox-portal-detection.com etc.

Specifically, there are persistent, periodic and repeated connection attempts to (just copy/pasting from the first page of firewall report; there are many more as well as similar connection attempts from thunderbird as well): firefox-settings-attachments.cdn.mozilla.net:443 assets-prod.sumo.prod.webservices.mozgcp.net:443 content-signature-2.cdn.mozilla.net:443 push.services.mozilla.com:443 etc

These begin at the startup of the browser/mua and continue throughout the session. Given that none of the sites actually browsed have anything to do with mozilla per se, and given that various privacy-violating features such as DNS-over-HTTPS (yes, that's a not a privacy-enhancing feature but the opposite - it just shifts the surveillance point from the ISP to the DoH provider) and other similar "features" are disabled in-browser, there should be no user/browser connections attempted to mozilla servers.

Also, by setting up a local security MITM proxy in order to observe and analyze the content sent to and received from these services and configuring the browser to connect via the proxy, the browser seems to *stop* trying to connect to these services, which indicates *active* measures by the browser/mua to avoid it's browser-fingerprinting and location-revealing content from being intercepted and analyzed.

This is especially concerning as Mozilla actively brands and markets it's products as privacy-respecting, as for-user-rights and as away-from-big-tech-dominated. Consequently I perceive this as complete breach of trust. Even by just *attempting* such phone-home connections a leak of metadata occurs, identifying the IP, the browser and consequently the user and user's location, sometimes actively (such as was the case with now apparently discontinued location.services.mozilla.net). Combined with whatever content these connections carry, this constitutes a serious breach. And there seems to be no way for the user to configure the browser to stop making these connections, other than by using an external application firewall.

And to top it off, with Firefox version 155.0.1, the browser now outright refuses to connect to *any* sites at all if firefox.settings.services.mozilla.com:443, firefox-settings-attachments.cdn.mozilla.net:443, firefox-portal-detection.com:80 and content-signature-2.cdn.mozilla.net:443 are *externally* blocked, at least on that profile (which worked just fine prior to upgrade to 155.0.1), showing a spinner and waiting indefinitely (not even timing out). These are the *only* connections it even attempts, completely ignoring the actual site that it was told to connect to. So that's at least 4 privacy-violating, security-policy-violating phoning-home connection attempts and a complete disregard for user's actual, sanctioned connection request.

Had my laptop serviced at Best Buy, but upon booting it up the icon for 1Password in the upper tool bar was missing. Trying to figure out how to add it back. I use Mozilla Firefox and have Windows 11.

This device is essentially a thumb drive made by MOPAR that contains automotive serve diagrams for a Jeep Wrangler. When you boot this device with Firefox being the primary browser you get garbage instead of schematic drawings. If I make Edge the primary browser the card boots properly and runs. This a legally obtained card with no password system on board.

I am in the UK. I happen to have used amazon UK enough recently that it gets into the top-8 history in the address bar on a new tab.

And then the Amazon sponsorship – which is turned off in settings – corrupts it and "normalises" it to reference amazon.com. Screenshot attached with the misalignment highlighted.

Of what possible use is it to surface a top recently-used site when the address gets corrupted so it does not point to the site that has been used? This is idiotic.

Hint. When sponsored sites are turned off, respect that choice. Do not allow them to corrupt the experience. And even if it weren't a corruption introduced at Amazon's behest, domain normalisation is absurd when the site in question is geographically distinct. There is no possible excuse for it.

Hello

I have Firefox 154.0 on my 2 PCs that have Windows 11 and both computers are updated fully as of 22nd August 2026 with both Windows updates and Nvidia drivers.

Background: On my 2 PCs I have an "old" stationary PC with Geforce 1070 TI card, and I have a laptop Asus Vivobook 15 PRO with a Geforce GTX 4600 card. Both computers working fine and no issues so far.

Symptoms: I updated Firefox. Note! I always update Firefox on my computers, so it wasn't a clean install of the browser. And suddenly on both computers there were black artifacts all over screen and flickering when scrolling on Facebook or Youtube. Also even worse on sites were you drag a div and the browser turns into a 1-bit disco.

Workaround that seems to be working for me: I went to about:settings and searched for hardware on my laptop (the one with 4600 card) and searched for "hardware". Then I disabled the hardware acceleration thing, or whatever it was, but unchecking the result after search. Then I restarted my laptop not using hardware acceleration and it worked fine.

Then again I search about:settings for hardware and checked the bottom of the 2, not sure what the first one was. And restarted computer.

Now I don't have those black artifacts and flickering any more.

Not sure if that somehow triggered something that works for fresh installs or not.

Anyway... I can't submit a ticket since I can't reproduce the error it's no point submitting to Bugzilla. But hopefully this makes sense anyways... But I'm pretty sure you guys are aware of this issue already. But posting anyways in case it might help.
