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

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

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)"

I see many complaints about this new version v 149 for the Mac. The most outrageous one is that you can no longer drag links from a browser page (try BBC) to an email or a doc. You have to copy the link then it won't turn blue and only when received will it show up as a link. Like many others after 30 years use preferred over Safari and others I am seriously losing patience with Firefox. On the very day you announce split screen for Ff windows - you disable a vital feature that has worked for years causing me to waste so far 60 minutes of my hard pressed work time. Maybe this will be corrected in the next upgrade. But I am now intending to avoid all Firefox upgrades for 6 months after being offered. I doubt anyone on this forum will come back on this but my set-up is Mac OS Monterey - and Firefox v 148 worked perfectly before today. I hesitate to try and install the previous version because I am not used to doing such tech moves. Perhaps someone in the Mozilla head office congratulating themselves on the marvellous new upgrade will come across this but I doubt it

Please tell me how to disable adblocker for a site. I am trying to read my local newspaper and I cannot access it due to this issue. I've googled it and cannot find the answer. Please Help!!!

I am writing the following sentence in html: <a href="https://www.users.no/ingehelland/Desktop/QDT_article.pdf">QDT_article</a>. Firefox refuses to open the file

When a video is popped out, in PiP mode, and the "owning" page is scrolled such that the video "origin" scrolls off the viewport, the PiP video pauses. If the video is started again, and the page is scrolled more, it will re-pause.

This seems to be a Firefox behaviour and not a site-specific one.

Is there a setting to keep the video to continue playing?

This would be helpful on Twitter/X, for example, when scrolling the timeline with a PiP playing from a tweet.

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 have firefox running on my mac desktop, macbook and iphone. Starting yesterday the firefox password manager has stopped working on my desktop - it won't make any suggestions for passwords on web pages. I've been reduced to going to about:prefererences, manage passwords and manually searching for my password. It still works on my macbook and iphone. Any suggestions as to how to debug this?
