Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

To sign into Chatgbt I used my google account. Mozilla asks me "do I want to store info in persistent storage?" I click "learn more" about persistent storage. It takes me to a page that has zero mention of the words "persistent storage". That is a huge UX error. It says to me that really, you don't want me to know about persistent storage, and prefer that I remain confused and feel forced to agree to things I may not really want to, because you're making it difficult to understand what's actually involved. Not cool. Definitely now considering changing my browser after over 20 years.

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

It's pretty much in the title. My in box freezes up and no emails arrive. Microsoft will drop drop down a box asking me if I want to open THUNDERBIRD and says make sure I'm using a trusted server - app??? I don't understand any of this!

This might be quite "old man yells at cloud" of me, but oh my god I am so fed up of everything putting AI in as a "feature" for no reason.

1) No one asked for this. 2) It is bad at doing whatever it is designed to do. (It's not helpful, it's not even neutrally unhelpful, it's ANTI-HELPFUL.) 3) It is always on by default, or worse, impossible to turn off.

At the very least AI features need to be off by default, because it's rubbish.

Firefox is meant to be a bastion of sanity and safety in a world of exploitative techbros trying to steal our data and trick us into making money for them. So-called "AI" goes against this. Please, Firefox, be better.

As of 20th Nov 2025, here's how to turn off AI features. Go into about:config and set all of these to false (yes, you’ll have to copy and paste them one by one):

• browser.ml.enable
• browser.ml.chat.enabled
• browser.ml.chat.menu
• browser.ml.chat.page
• browser.ml.chat.page.footerBadge
• browser.ml.chat.page.menuBadge
• browser.ml.linkPreview.enabled
• browser.ml.pageAssist.enabled
• browser.tabs.groups.smart.enabled
• browser.tabs.groups.smart.userEnabled
• extensions.ml.enabled
• browser.search.visualSearch.featureGate

in addition to nuking AI, it’ll also speed up your browsing

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

I have accessed the particular website many times but today it says, "Hmm. We’re having trouble finding that site.

We can’t connect to the server at shop.naturalcompounder.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)"

My user experience on Firefox is being severely impacted and is making me angry. I watch the updates calendar they are once a month. So why can i not go a whole week it seems with a necessary Firefox update to my browser that impacts the performance of websites. I like to have multiple tabs open over a week or more. I don't want to close and reopen my tabs every time I want to use my computer. SO WHY are there SO many updates. It's seriously making me want to uninstall your browser and I have been using Firefox on multiple devices for years. More than 20 years now. It's seriously ridiculous to have a major update every week or even every other week where I have to shut down and save my work on ALL of my tabs just to update Firefox. I have never remember history and I am going to uninstall and reinstall from even greater security because I have serious concerns about the amount of data that big tech companies share with 3rd Parties and the government. I am an honest American citizen and I HATE being surveilled and having my private life sold to the highest bidder. But even though. the safety of your browser is a positive feature it becomes very difficult to WANT to use Firefox when my workflow is CONSTANTLY interrupted.

Seriously, You JUST updated on the 23rd/24th and now just two weeks later there's already ANOTHER update. And who even knows when that one dropped. I only checked it because sites were acting up. And EVERY TIME a site acts up it's because of an update. You have interfered with my user experience with Youtube, and Multiple Streaming Services, and Multiple Chat bots. It's thoroughly dis-satisfactory and disruptive, and ANNOYING. I want a tool that protects me while I am on the web. I do NOT want a tool that ruins my internet experience every week.

On MacBook Pro running Tahoe 26.3.1.(a), very often in the Search Box/Bar, a vertical gray oval overlays the last characters I've entered for a search. As it gets in the way, anyone know how I can eliminate this?

Thank you in advance!

This browser is not letting me connect with my pension website. It allows me to sign in, but the pages with my account are not showing up. How do I get it to recognize the website as safe?

I am a big fan of the new VPN feature that you guys introduced that is strictly for browser. There are only two current issues i have with them and its the limited bandwidth of 50 GB that is very low and i would like the option to pay a reasonable price for unlimited. Also when i disable the vpn for a website there is a blue pop up in the corner every time i tab over or open the specific page on a new tab that i can't disable or change the behavior in any manner.

'I am running fiefox version 147.0.3 in MacOS version 26.2. Every second time I start the program firefox tries to take 15GB of memory. The process does not respond (as this is equivalent to more than the memory available plus the swap space). I have to kill the process and the second time the program has standar memory needs. How can I help developers?
