I-Firefox Community Forum

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

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?

Netflix stopped working with Firefox saying that an update is required. My Firefox and OS (Win11) are completely up to date.

Update required

У меня Windows 11 Pro, скачивал firefox с прав администратора, но обычно после установки в правом верхнем углу появляется значок входа в аккаунт фаерфокс, которого сейчас у меня нету. Прошу если кто-то знает ответ или сталкивался с проблемой - помогите, мне срочно нужны пароли, которые остались на аккаунте

I just updated to 143.0.3, and unless I open FF to its full width now, my clear-browsing-data and zoom icons have been disappeared from my menu bar.

The reason is because large (one-inch!) empty spaces have suddenly been inserted at the far left end of the menu bar (next to the back arrow) and between the hamburger icon and minimize "-" sign. It's not possible to remove those blanks via customize.

I click on my "clear" and "zoom" icons hundreds of times a day and I prefer having my browser non-full-width (prefer 2/3 width).

Anyone know what caused this and/or how to fix it (apart from rolling back to 142). Once again Mozilla has broken something that worked perfectly for me for many years and I suspect it has something to do with more screwing around with tabs. (I do use a CSS file solely to keep tabs on bottom.)

Alternatively, is there a way to shorten the address bar? That might create room for my add-on icons to re-appear while leaving the spurious blank spaces on the menu bar.

Thanks in advance! --KK

I'm having trouble signing into to some online news sites especially videos. The screen shows activity without actually loading a video or website site. I can't connect, it just keeps spinning.

When I turned on my computer this morning, and opened Firefox, it froze, and had to be process-ended by Windows.

Subsequently, it also caused Windows Explorer crash.

I was forced to hard-reboot my computer, and restarted it to find all my tabs gone and unrecoverable, and all cookies deleted.

However, my browsing history remains.

Furthermore, my attempt at recovery of this data via the automated backup taken Monday 29 September 2025 - three days before this post - accomplished nothing.

I have looked in several places here, and found no help at all in recovering lost tabs. All threads remain unresolved.

Please provide troubleshooting assistance ASAP.

(And please be aware that the software had to be opened in order to post this question.)

Good morning, Woke up, noticed my screen on (was in sleep mode), guessed PC had restarted itself overnight, that happens, opened Firefox, click sandwich Click History "Recently closed tabs" and "Recently closed windows" are not options I can click...

what the heck please help! I'm going back to bed....

Dear Firefox Team

I recently had to uninstall and reinstall Firefox. When I logged in, I thought my extensions/themes would be there, but that wasn't the case. Can you help?

Thanks.

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

Hello..

Trying to make the Firefox as my default but... the Web browser" is not visible in Settings.

PLEASE guide me to the right link..

At this time the Microsoft Edge is selected permanently.

Any suggestion is welcome.

Hi,

When i switch between two tabs by clicking with my external mouse ( I am on one tab and then point and click on another) and then directly start to scroll the page zoom like it does when i hold ctrl+zoom. What causes this?

It does not do the same in other browsers or other apps. It does the same with external mouse and track pad.
