Firefox 技術支援討論區

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

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 trust this message finds you well. I am currently using Mozilla Firefox as my preferred web browser and I'm interested in ensuring that I have the latest version installed for optimal performance and security.

Could you provide a step-by-step guide on how to update Mozilla Firefox to the latest version? I'm curious about the frequency of updates and whether the process varies for different operating systems I'm using windows.

Additionally, I'd like to understand if there are any precautions I should take before initiating the update, such as saving bookmarks or ensuring compatibility with installed extensions.

Furthermore, are there any notable features or improvements in the latest version that I should be aware of? I want to make the most of the browser's capabilities and stay informed about any enhancements.

Thank you in advance for your assistance. I appreciate your expertise in guiding me through the Firefox update process.

Best regards,

Hi, I want to delete my acccount entirely and start fresh, I login to the website just fine, but when going to the "Delete Account" button I keep getting an "Incorrect Password" pop-up.

I've changed the password twice now, logged in just FINE, yet keep getting told I'm using the incorrect password when trying to delete my account.

I've tried on multiple different browsers now to delete the account and it's just not working.

I really wanted to swap over to Firefox but everytime I try, I get some insanely stupid issue that never ends up being resolved, I've found another thread from 2021 about this and they stated it never got fixed and they had to make a whole new email just to use the service.

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.

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 recently took a hit from potential malware while looking for a owners manual. I now have a popup that looks like the one attached. It looks to be from Mozilla, but I can't be sure. Can you help with this?

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

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?

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.

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.

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

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.

When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

Dear Colleague

Please let me know how to stop these websites from automatically opening.

Thank you.

Hi,

I use Firefox Developer Edition as my default testing browser. I have it set up to clear the cookies and site data when Firefox is closed. For my normal browsing I use regular Firefox (currently version 120.0). I was looking through the settings on 121.0 beta Firefox Beta November 21, 2023 and saw it has the very useful Cookie Banner Blocker: When a site asks if they can use cookies in private browsing mode, Firefox Developer Edition automatically refuses for you. Only on supported sites.

According to the https://support.mozilla.org/en-US/kb/cookie-banner-reduction?as=u&utm_source=inproduct this was introduced in Firefox version 120. However I do not see it in my regular Firefox 120.0. Both browsers say that "Your browser is being managed by your organization." I can change the proxy settings in regular Firefox 120, but not in Firefox Developer beta 121. Although both have the same sentinelone 2023.1.4.650 extension set.

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.
