Firefox Community Forum

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

Hi, just to say, sorry, I’m an absolute idiot, I don’t understand tech at all. I have a VPN, privacy badger and ublock origin. These issues continue whether these three things are turned off or not, so I believe it must be to do with my Firefox settings.

Everything was fine, but now all of the sudden, certain elements of pages will not load.

So for example, today I tried to go to Gizmodo and look at a Star Trek page. Cool. https://gizmodo.com/star-trek-day-announcements-include-a-lego-collaboration-and-a-youtube-kids-series-2000655142

This is not the only site, just an example.

Clicked the comment button to see what people are saying. It won’t load the comments. The comments are completely blocked. They don't exist. When I try to look at the comments, it just shows me another part of the webpage, can't even see the comments.

Thought it was just this site, but then today I was on a plastic surgeon site in Europe to make a payment and it wouldn’t load the payment page.

I tried turning off badger and unblock to make the payment, and it didn’t work.

Honestly I really have no idea what the problem is, I know I’m doing something stupid but I don’t know what it is or how to figure out.

Any help on figuring out what’s going on or where the hiccups for these might be would be welcome.

Thank you!

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.)

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.

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

It has always been the case that when I closed Firefox, it asked if I wanted my open files saved and reopened when I opened the browser again. I needed to restart my laptop and I decided to close Firefox first. It asked if tabs should be saved and I said yes. After I restarted the laptop and reopened Firefox, all of my open tabs (I think about 35) were gone. Can I get them back?

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

Hello,

Google Drive today stopped loading properly. I keep getting the rotating circle or "working" in the lower left corner of the browser window. I can get it to load fine in Safari and Chrome.

Docs and sheets I already had open, I seem to be able to interact with and edit normally. But navigating the main file path in Google drive, opening folders, and opening files isn't working.

I would really prefer to not switch browsers, as my entire workflow is set up on Firefox.

Suggestions?

Thanks, Sarah

Hi, I recently upgraded my Macbook Pro (running Sequoia 15.6.1) to the Firefox desktop app 143.0.1 (aarch64). Google Drive, which is my company's file-sharing and collab platform, no longer allows me to open and edit documents unless I clear my cache on a daily basis, which is not a sustainable workflow. I either get stuck on "loading" (see screenshot) or the file opens but I cannot edit it. I've also turned off Enhanced Tracking Protection (see screenshot).

I love the Firefox browser and hate to leave it but I'm at my wits' end. Hoping someone can help - thanks!

So i've lost access to my email on. my old mozilla accounts and upon logging in on a new device im being asked for a code to the email which i don't have access to anymore is there a way that my info can be synced to a new one. Thanks

I've usede Safari for years, but want to try Firefox. I've tried to import data, bookmarks and so from safari, but can't do it. Firefox says: Select the Safari file. But which one? And where do I find it? I've find the app Safari – but there's a lot of files underneath it.

My instagram does not open on my firefox browser. I have cleard all the cookies and cashes. I tried Incongnito, hot spot sharing. I have tried everything its still not working. Can you help me?

Hello,

When I try to visit a specific journal site that requires authentication, the browser automatically redirects me to an authentication page that I have used before. This is very annoying because every time I click a link to the journal, I’m sent to the other portal and can’t access the article. I want to stress that I haven’t installed any add‑on that would cause this redirection. I think I did that myself manually but I have no idea how. I’ve already deleted the cookies for both sites, but nothing has changed. I hope that makes sense, it’s a bit difficult to explain.

I'm using firefox 147.0, on mac Tahoe 26.2.

Thanks for the help !

Hi folks,

New to Mac. I have HDR in Safari, but cannot find out how to enable in FF 140 ESR. I do have Wide Gamut enabled and working.

Is there a way to turn this feature on?

Thanks!
