With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

can someone please tell me why firefox is trying to install this unwanted file.....i run bitedefender everyday and everyday this pops up it is ANNOYING Online Threat Prevention

firefox.exe attempted to establish a connection relying on an expired certificate to sync.contextualadv.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk. Add to exceptions

please email [edited email from public community support forum] ......

I closed a PDF file but can not move it to another folder. Windows says it is open in firefox. I closed firefox and it still says it is open in firefox. I even restarted windows and it still says it is open in firefox. How do I get firefox to close and release the file?

I've been using Firefox for years because more popular browsers like Chrome and Edge have anti-features I dislike. In recent years, however, it feels like Mozilla has been more eager to follow trends set up by it's larger competitors even when those trends seem destructive to the principles that used to be at the core of this project. AI is the final straw for me. I don't understand why I would even use Firefox over Chrome if both are full of AI anyways. Even if AI wasn't a deal-breaker for me, I'm worried Firefox will make similar decisions later. I want out.

Is there any good and maintained alternatives to Firefox? Something like how Firefox was just a handful of years ago? Maybe a fork of an old version?

please provide directions for fixing the navigating inside NEwsmax site

On the https://addons.mozilla.org/en-US/firefox/addon/nordvpn-proxy-extension/ tab, NordVPN appears to be installed as the button indicates "Remove". I have logged into NordVPN but do not have the NordVPN icon in top-right corner.

Configuration: Windows 10 just installed: October 14, 2025—KB5066791 (OS Builds 19044.6456 and 19045.6456) FireFox: 143.0.4 (64-bit)

A couple days ago, some weird issues have started:

• All my bookmarks are gone
• Any of the buttons in the UI that open a smaller UI do not work (such as the 3 bar menu)
• Similarly, right clicking to open a menu (such as "Save Image") also does not work
• Any dropdown menus in websites seem to also not work. For example, in this very support page, I could not select an option in the "Which topic best describes your question?".

I can't restart and troubleshoot Firefox since I can't access the 3 bar menu.

I have no idea how 100k people can review an extension labeled ICLOUD PW EXTENSION and you guys can't either remove it for the scam it is or show it has your approval as an extension up to FireFox security standards. 2.7 stars 100k reviews looks like a scam. Simply my feedback. Can't tell if I should trust so I'll never trust it until it's sufficient enough.

Hello,

My firefox shows different time zone on calender when i want to sign up for events, while my macbook shows the right time. How can i fix it?

Thanks

Maybe this is counter intuitive, and/or I don't understand pinned tabs, but is there a way to have pinned tabs visible in the tabs list, instead of hidden.

I find it very inconvenient in a variety of ways.
