Firefox Community Forum

I just got a new Mac laptop and I again chose Firefox as my default browser. I used to have a series small tabs of frequently accessed websites at the top of the firefox home page...like my google email, Amazon, etc. I tried to do that again, only now I end up with a whole series of websites and bookmarks all across the top of the page : Yahoo, Bing, Wikipedia, Twitter, etc,. etc. I want to get rid of this lineup and I'd like to be able to add my personal email, and a few other frequently visited websites. I thought that these small tabs at the top of the page were called shortcuts - but after turning the toggle on an off in firefox settings and not changing a thing - I don't know what they are or how to delete what's there and get my person tabs back. Please help.

For some reason, my Gmail page doesn't show the icons on top at all. Like the archive, mark as read, and the others on top of the mailbox contents. They show up on both Chrome and Edge, so this seems to be a Firefox problem.

Computer being used with issue: HP ProDesk 600 G2 DM (Windows 10, 16GB RAM) So can this be fixed or should I just use my phone for Gmail?

The Smart Window feature caused CPU usage and memory to max out. Disabled it as soon as I could find the setting to do so (Settings/AI Controls and BLOCK "Smart Window") and overload disappeared immediately. Everything is working fine now. What a disaster! Also did not find the interface terribly impressive or informative. Quite the opposite: It was almost deliberately vague and not at all intuitive.

Contrary to the claim that "Smart Window automatically groups related tabs, so everything has its place and what you need is easy to find" it just just described each of my open tabs (despite several related tabs being right next to each other) instead of supposedly grouping them by subject matter. That's basically useless -- I can see that for myself. Definitely not ready for Primetime.

Windows 10 Home, Firefox Version 155.0.1 (64-bit), Dell Inspiron 15 3000, installed RAM 8.00 GB, Storage 119 GB

Yes, I've been contemplating adding memory and/or buying a new laptop. But a new feature shouldn't totally freak out my system without some sort of appropriate warning about memory prerequisites, etc.

Hello,

I have been unable to update Firefox past 132.0.2; every time I download an update and install/restart, all tabs automatically crash upon loading regardless of the website. I can load local pages like settings or about:config, but anything that actually uses the internet goes straight to crashing (including sites as simple as google.com). I have tried restarting in Troubleshooting mode to no avail. There are no crash reports when I pull up about:crashes, so unable to post IDs here.

It is not an internet access problem (I am [unfortunately] filling out this form from Edge), and with reversion to 132.0.2 everything moves along hunky-dory. I am also able to use the newest version of Firefox on all of my work devices, so it appears to be something in particular with my person PC. Problem occurred with both Windows 10 and Windows 11.

Any help would be much appreciated- I didn't mind an older version of Firefox that worked, but there have been some MFA logons that refuse to go load in v132 so it's becoming something I'm less able to ignore now. TIA

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.

How do I remove "add sitename"* from Search bar drop-down menu?

• sitename refers to whatever site you are on at the time

I have no use for this option and find it overly invasive. I have searched everywhere for solutions and have not found any that work. If it is not currently "removable", please make it so.

Thanks

this old man cannot find the home button? I thought i had looked everywhere i could imagine but it must be right where i couldn`t imagine, I would certainly appreciate some help. Thank you for your time and effort.

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

I installed and update this morning, September 7, 2026, but now all my previously saved bookmarks (prior to September 7, 2026) are not accessible or shown. How do I recover all of them?

I am suddenly finding I cannot scroll a thread in Chatgpt! What changed in the last 2 days? It has been working fine for 2 years. I am on OS mojave 10.14.6 on a 2015 Model Imac.

... click on (eg.) 'Interactive Map' and nothing happens, at least not here. Chromium has no problem.
