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 beg of you, please do not go forward with the AI focused policies. AI as it currently stands is a rapidly sinking ship that a LOT of consumers hate, and that group is coincidentally the group that most frequently uses Firefox. By pushing forward AI-first policies, you are alienating your userbase, destroying the privacy and usability that makes Firefox special, and you're upsetting millions of people that love this service. Please, for the love of god, DON'T GO FORWARD WITH AI. Stick to what makes Firefox special, and it will flourish as every other browser becomes more and more unusable.

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

Why suddenly and for no reason after years and years on the same computer am I not able to access espnaudio.espn.com Makes no sense!

When I click on a link in emails to open in browser if email has display problems, it opens a blank webpage and a small window that I clicked on OK reappears with Firefox as my default browser. See attached screenshot. If I select Edge to open the email, it works fine.

Please address.

Please don't put AI into firefox. I moved to this browser to get away from the google privacy violations. I don't want to have to move to a different browser again.

there is a payment methods label in settings but thats is. its just a label under it immediately comes save addresses from other articles i can see that there should be a saved cards button but i have nothing why?

I use LastPass and I cannot open any login information from the vault. I click on "Launch" (picture uploaded) and nothing happens. If I have a site open I can auto-fill the Username/Password. Some of the sites are tailored to a specific page - I rely on this. It works in Edge and Chrome. It did work before today in Firefox (can't say when specifically). Firefox password management disabled.

Svp, comment changer la couleur de la barre latérale ?

La mienne était toujours blanche, mais vient de changer à mon insu pour du bleu ...

Merci de m'aider.

I have Firefox 146.01 on 2 windows computers (windows 10 and 11), and on a samsung android phone. I have several extensions (eg uBlock) and I use ExpressVPN.

My mozilla account has a display name and primary email which I verified, and account recovery key enabled. There's no secondary email, no two-step authentication using a third party app. I can readily log the browser back into my mozilla account by entering the password and emailed 6-digit confirmation code, but then it logs me back out within an hour. Each of my 3 devices logs me out repeatedly.

In the address bar I type about:sync-log, and I was able to find the below lines in separate areas of several logs: DEBUG Status.login: success.login => error.login.reason.no_username DEBUG Status.login: error.login.reason.no_username => error.login.reason.no_username ERROR FxA rejecting with error UNVERIFIED_ACCOUNT, details: undefined ERROR Background refresh of initial profile failed: Error: UNVERIFIED_ACCOUNT(resource://gre/modules/FxAccounts.sys.mjs:1669:18) JS Stack trace: _error@FxAccounts.sys.mjs:1669:18 withSessionToken@FxAccounts.sys.mjs:876:18 ERROR Sync encountered a login error DEBUG Exception calling WrappedLock: Error: Login failed: error.login.reason.account(resource://services-sync/service.sys.mjs:1053:15) JS Stack trace: onNotify@service.sys.mjs:1053:15

Based on the above lines, can someone help me figure out why firefox/mozilla keeps signing me out?

Thanks so much

Hello

After a recent update, the bookmarks menu changed—when you click a certain line, it glows bright blue. I understand this is for ease of use while using bookmarks, but I'm used to leaving this menu open all the time, and after these changes, the blue glow is very distracting.

In light of this, I'd really like to know how to restore the old display, or, if that's not possible, I'd like to see special personalization settings for this type of thing in future updates.

Hi!

I've had issues with Firefox now for quite a while and they only seem to be getting worse. Performance is really bad, it's lagging while browsing, especially infuriating when typing as the letters come out at a stuttering pace. I've tried disabling extensions one by one, I've tried troubleshoot mode and experienced no major difference.

If I can't solve this soon enough I won't be able to keep using Firefox, as the experience is so frustrating. And it would be a shame since I've come to like it quite much.

Thanks!

Why isn't the Firefox browser supported by many services and social networks? They even state in the warning that Firefox is not supported! Why should users tolerate this?

Почему браузер FireFox не поддерживается многими сервисами и социальными сетями? Так и пишут в предупреждение, что этот браузер FireFox не поддерживается! Почему пользователи должны терпеть это?
