TL;DR : Disqus comments used to work while using privacy Strict mode now it doesn't.

After years of it working out of the get-go while using Strict mode up till recently (about a year ago this was really low on my priority list) refused to work I though it was my Ad blocker was causing issues but after setting it in the filters to allow and even after turning it off still no dice.

Removed all add-ons tried again still Disqus comment section refused to load in the websites I regularly visit. So after giving up, I just look around in the browser setting to see if there is anything that may cause conflict with certain scripts from running.

This started a few weeks ago. I thought it might have been because I synced the passwords with other devices. I reverted it back.

When in about:logins, I click on the log in button but nothing happens.

This is the message I get. "Please unblock challenges.cloudflare.com to proceed." I can do nothing.

Things I've tried. Adding exceptions in the privacy settings in 2 seperate areas. Resetting Browser deafults. Turning off all vpn's and addons.

Nothing works.

This is the site https://1337x.to/

On a couple of sites (e.g. Petapixel) when I click "Load Comments", nothing happens. I suspect this may be because Firefox security is preventing comments from loading because of site tracking or other security issues. Is this the cause?

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

I am trying to log in to the Tesco retail site, and get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server. Reference #18.26cc19b8.1700734342.438f9dd8 This is a new problem - it was working fine a week ago, and I have made no intentional changes to the Firefox settings. I went to the Settings: Enhanced Tracking Protection, changed it to Standard, and added the Tesco site as an exception (this was following the advice on some other "Access Denied" posts) but it made no difference - I still can't log in. Everything works fine on Chrome, but I would prefer to keep using Firefox if possible. Any suggestions? Thanks

I can't seem to access one website that I used to visit daily: www.leftwinglock.com

I have no issue with any other site that I visit daily, and my co-workers are able to access that site so it is not down.

Is there something in my settings that is preventing me from viewing this site now?

Thanks.

Release notes for Firefox v120.0 https://www.mozilla.org/en-US/firefox/120.0/releasenotes/

Among these release notes, "Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy." How good or bad is the feature? There's the canvas blocker extension which might now be obsolete, then again without details this is impossible to anser. How exactly does the Canvas API enhance Fingerprinting Protection with this new update? The release notes don't explain that, where do i find details? Firefox should use this for all windows not only private ones.

Among the relase notes, "Firefox is rolling-out Cookie Banner Blocker by default in private windows for users in Germany during the coming weeks. Firefox will now auto-refuse cookies and dismiss annoying cookie banners for supported sites." I'm not german but would still like to use this feature as the cookie agreement popups are extremely annoying and time intensive to dismiss. Apparently in about:config "cookiebanners.service.mode" is the precise setting name. Does it have to be set to "1" to be active? This setting seemingly has the potential to replace extensions such as "Cookie AutoDelete" or uBlockOrigins Filterlists/Easylist cookie notices. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox has enabled URL Tracking Protection by default in private windows for all users in Germany. Firefox will remove non-essential URL query parameters that are often used to track users across the web." I don't get why this would only be active in private windows and germany. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox now imports TLS trust anchors (e.g., certificates) from the operating system root store. This will be enabled by default on Windows, macOS, and Android, and if needed, can be turned off in settings (Preferences → Privacy & Security → Certificates)." I've no idea what to think about this, is it a good or bad change and why? Don't try to fool me here, i want honest ansers no BS... is there potential for abuse? If Firefox uses CA's from the OS then what happens to firefox internal CA's, remain unchanged?

Among the release notes: "Firefox supports a new “Copy Link Without Site Tracking” feature in the context menu which ensures that copied links no longer contain tracking information." While this is a welcome change, i'd be much much more useful to replace “Copy Link Without Site Tracking” with “Open Link Without Site Tracking”... Otherwise there's the needless waste of time manually open a new tab and paste the link... This completely lacks any logic if you ask me, why didn't mozilla make it as i suggest above in the first place? Why the manually klick klick waste of time?

Lastly a question unrelated to this update, when RFP is enabled and the browser-screen-size is spoofed, if i go into fullscreenmode by accident, will this expose my true resolution or not?

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

So I have two different accounts for one website. However one of them I use very rarely, maybe once in 2-3 months the other one i use almost daily. Therefore I have saved both logins in Firefox and I can see them in my passwords.

The problem is that whenever I try to access the website, Firefox auto-fills the "second" account, the one i only use rarely. What this means is that instead of me being able to just press login i have to delete the username filled in by Firefox and select the other one. So what i would like to do is to maybe tell Mozilla that I want it to use the other account for auto-fill.

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

Hi, Mozilla Relay/mask is connected to an old, defunct email address. How do I change that? The verifications are going to the old address that I can no longer access.

All of a sudden the Firefox password I've been using for a long time stopped working. I went through the reset process, set a new password, and it still doesn't work! What I am doing wrong? Keeps asking me to re-enter the password, and when I do, it says it's not correct. Is this a widespread known issue?
