Firefox Community Forum

All of a sudden my Apple laptop Firefox is responding VERY slowly. It takes about 10 seconds from hitting enter to any screen response. I've tried it with and without my VPN on, and there's been no changes to my Avast security software (that I know of). I've reviewed the settings/preferences without any clue about what is happening and what I could do to minimize it. I've run a speed check which resulted in 287 down and 190 up, so it's definitely NT my network.

I am a developer.I want to know the source code location in Firefox that reject tracker cookies and the code location for obtaining the tracking protection list after installation

Dear Mozilla support,

I represent a company that is providing a SaaS-service, in said service our marketing teams wants to implement thirdparty scripts, but we need to make sure that those scripts don't have access to the DOM to ensure the confidentiality of the information in the service.

What I've found out so far is that fenced frames seems to be a good way to solve this, see the following https://developer.mozilla.org/en-US/docs/Web/HTML/Element/fencedframe.

However the implementation for this element is still lacking in firefox, so i'm wondering if it will be implemented and when if so. We know that the feature is still experimental but it's something we would like to test and see if it's the way forward for our thirdparty scripts.

Lately I have difficulties logging-in to my two different e-mail providers. I have had them for years without any problems. Both don't let me log-in anymore. They want me to deactivate my ad-blocker - but I do not have an ad blocker installed with Mozilla Firefox! There is no such sign on the upper right and in the themes there is none either. The data protection is on standard. Although I agree to cookies but this doesn't help at all. So: where is the problem and why all of a sudden? What can I do? thanks in advance for your help.

Hi! I'm having trouble with Firefox while shopping on Scottish Kilt Co., a store for custom kilts and Scottish accessories. The website is slow to load, and some images aren’t displaying properly. Is there something in my browser settings I need to adjust for a smoother shopping experience?

I’ve already cleared my cache and updated Firefox, but the problem persists. Any tips on improving performance or troubleshooting would be appreciated!

Thanks!

I have always had them setup. And I would expect a prompt when my computer had been shut down, or OS/FF had updated - seems normal. As of a couple weeks maybe months ago, I'm being asked for it what feels like constantly. In fact, It just asked me twice back to back withing the same session/tab/interaction with Passwords. That feels like a lot, esp if you actually have longer and more complex pwds than 90% of us. (And me sometimes, not claiming to be a pw angel or anything lol). But personally, Mozz/FF passwords fall into the top tier of my brains security hierarchy, along with my Apple Account, private keys, device encryption, MFA recovery, etc...things you'd generally be sure to incorporate best practices with and really don't wanna forget or lose. I don't really love the idea of turning it off, buuuut getting a bit grumpy about being pestered all day from Firefox.

So bug? Updated policy? I just woke up form a Coma and simply don't recall 2024? Hopefully not the third one.

On an M4 Max running Sequoia Version 15.2 (24C101) using FIrefox 136.0.1 at the moment, but have noticed the same on a Yoga/Windows 11, iPhone, M1 Macbook Pro.

Privacy/Security is set to Strict. No sus permissions I can see. HTTPS only. DNS over Cloudflare (Default Protection). No exceptions of any type granted. Aside from Mozilla (for Extensions), and Google (for Popups).

Thanks yall.

Oh (and I should prob open a proper ticket but while) but I'm here, and I just noticed the line about "On macOS, some background tabs will be moved to lower power cores, reducing energy usage." from a recent Firefox update brief. I've been having a rough time lately on this M4 Max - 16 cores, 64GB mem with tabs freezing up the whole browser, every window. Sometimes the whole OS. Not specific to any certain site, and has happened with 1 windows and 3 tabs open just as often as 4 windows with 40 tabs open. And usually I cant even get to Activity Monitor at that point to see if it looks like a memory leak, or whatever. And if I can get it to shut down (the browser), it will get into this loop where it just loads back up all the same windows, and that same particular tab will lockup again as soon as I click on it. And it takes foreevvvver to load back up even when I don't interact with the browser aside from CMD-Tabbing tf out of there. Tbh I'd prefer FF to launch clean after being told to shut down. Always have the option to load recent windows anyway....

^ aaand then saw the blatantly obvious checkbox to turn off reload on start my bad. 😅

Sorry last thing - what exactly does "We've made some educated guesses about your current browser and operating system." mean? Yeah that sounds straightforward, and I would expect that from most websites? I think? I know you want to be transparent, but that phrasing sounds weirdly aggressive lol
