its very distracting, would be very gratefull for any suggestones if any one can 

help thanks

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.

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?

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

The AccuWeather part of the Firefox homepage says I'm in Portland, Oregon, USA, but I'm not even in the same country. I tried to change it according to the directions I found earlier, but the only drop-down for my city was another city in the US but none in any other countries. So now I can't change my location. How do I change my location? It wasn't like this yesterday and I have no memory as to how it became "Portland, Oregon" since last night. I don't even have a VPN so it isn't that. How do I change it back to my area without using my exact location?

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. :)

• (Nope - computer not eligible to upgrade to Win 11. My processor isn't fast enough, I think.)

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

In version 143 there is no rollup window option that allows a linux system to roll the window up out of the way. The icon is a caret located in the top right corner of the window.

Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

First, why does the "recently closed tabs" doesn't work if you close an entire firefox window?

second, why isn't there a place to search through your tab groups?

I just accidentally closed a firefox window with a lot of tabs, including unnamed tab groups.

This is a pain for all browsers, but firefox took it a step further.

There is a "recently closed tab" page which is really convenient, until you need it most when you accidentally close multiple ones. On top of that, I lost multiple unnamed group tabs.

Am I missing something, or is the experience still subpar? I've been a power user of firefox for years now, and I get why I get clowned by chrome users ngl.

Can the notification for upgrading be controlled on ver 143 on linux. It keeps appearing and as a user I should be able to silience or have it notify me at a period I prefer instead of interrupting browsing.

Using version 143 PIP does not work on different workspaces. If I open PIP the PIP only remains on the desktop that FF is on and the PIP disappears on othe workspaces.

I'm using Ubuntu 24 with the XFCE desktop. I'm installing the debs straight off packages.mozilla.org (currently 143.0.3).

Firefox's title bar, and window manager buttons do not have the same look and feel as the rest of my windows. And I have no idea where they're coming from.

They do change appearance in response to picking the different styles in Settings > Appearance, but the changes appear to be limited to colors only. The minimize, maximize and close buttons look differently than on all other windows, and they are more spread out than in, and the shade button is nowhere to be found.

I'm attaching two small images, the first one is the standard set of widgets all other windows have, and the second one is Firefox's odd duck. I could not find anything in settings. "Extensions And Themes" shows that "System theme" is enabled. Well, it's coming up a bit short...

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

When using YouTube system freezes between 5-30 mins, of start of any video. I have troubleshooted, i have checked every extension, i have run every diagnostics on hardware and software , checked and updated every driver but no results i tried checking online but didn't file any solution , the only thing i can do is to reset my system, it does not happen in any other situation. This is happening since the start of Oct'25, if anyone has any idea how to solve this kindly help.

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

My problem is the following. The website of my favorite football club regularly embeds videos within their pages. Clicking of the video within the club webpage shows the video without leaving the webpage. Recently opening the club site with mozilla stopped enabling me to see the embedded videos. An example of what I see on my screen now when using mozilla is in the first image uploaded below - instead of showing the embedded video, all I see is a small red rectangle with a "play" button in it. If I press the play button, the video starts, but shows within the extremely small rectangle and I cannot watch it.

This is not so when I use Edge or Chrome, as shown on the second image uploaded below, showing the exact same webpage (the address is https://levski.bg/video/%f0%9f%94%b5-%d0%bb%d0%b5%d0%b2%d1%81%d0%ba%d0%b8-31-%d0%b1%d0%b5%d1%80%d0%be%d0%b5-%d0%b3%d0%be%d0%bb%d0%be%d0%b2%d0%b5-%d0%b5%d0%bc%d0%be%d1%86%d0%b8%d0%b8-%d1%80%d0%b5%d0%bf%d0%be/ ). The embedded video is clearly seen in its full size within the page, and when I click the play button it starts showing the video normally within the webpage without leaving the site and sending me to youtube, for example.

My question is, what is wrong and what can I do to start seeing the embedded videos normally again?

Thank you, Georgy Ganev
