Firefox 技術支援討論區

I am getting notifications with the Mozilla logo or sometimes with McAfee logo saying "5 Viruses found, your computer is unstable" and various other warnings. They all also say "via qltuh.titanicooler.top" I have attached a picture.

I have closed the browser, I tried clearing my cache, I have scanned using both AVG, AVAST, F-Secure Online Scanner, and Microsoft Safet Scanner. I am not quite sure what else I should do.

Thank You

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

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.

I have changed Firefox's settings to both Delete cookies and site data when Firefox is closed and to Clear history when Firefox is closes. But after making these changes Firefox is still holding onto my browsing history.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

All of a sudden I can't open a certain website. I opened the website a few days ago with no problem and have been using the site for years. (I checked to see if the site is down but it's not.) I googled how to unblock websites in Firefox and nothing I've tried works. I disabled Trackers for the website and I cleared my Cookies. I added the Firefox uBlock extension a few weeks ago to stop constant website popups (after I tried resetting Firefox) and I turned uBlock off for this certain website but I still can't access the website. I also installed Mozilla VPN last week. I'm using Firefox 122.0.1. What could be the problem?

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

For the second time in the last two weeks, Firefox has deleted all my saved passwords when the program has updated. This happens frequently and is REALLY ANNOYING. How do I stop it? I am now going to restore the files from back up, about half an hour wasted.

Thanks and look forward to hearing back from someone.

I don't know why, it is NOT Ancestry, as I can sign in to it on other browsers. I get this error message below.

Access Denied Error 21 What happened? This request was blocked by security rules. Your IP: 73.94.12.65 Incident ID: 6eae587fcef92d46

I have no idea what security rules, but I am working on a genealogy project and have never had a problem signing into Ancestry in multiple tabs before today. How do I fix this? Besides getting rid of Firefox, I mean. I have the same security extensions on this browser as I use on Vivaldi, Brave and Chrome - I avoid Chrome, but use Vivaldi and Brave regularly, along with Firefox.

I get the message under Settings: "Your browser is being managed by your organization". Clicking on that message shows that the policy DisableAppUpdate is true. Methods for remeding this situation do not work. Please advise on how to change the policy to allow update please

A customer shared his Firefox login with me to share his passwords. I logged in with his account, downloaded his passwords and logged out directly afterwards, but now he is reporting that he has ALL my passwords. How can undo this? I never gave him access to my account and I never clicked on sync or something?

It seems that there was an internal page for permissions, namely about:permissions. As I was trying to find an answer to my question, I found many volunteers at Mozilla Support would talk about this, but what I'm asking for is different. I'm looking for a way to list websites per permission, that is, when I want to disable a permission for a bunch of websites at once, I specify the permission and remove the websites I do not want to have that permission. In one of the questions on the site, an extension called SQLite Manager was mentioned and seemed to be the solution. This extension, though, doesn't exist anymore. If what I'm looking for can be done through this extension, I'd like to know if there is an alternative. If it doesn't serve the purpose that I am talking about, I'd be happy to know if there is a different workaround.

Hello,

With the previous version of Mozilla Firefox, I was able to preview my work by passing privacy.file_unique_origin to false.

Now with the new update (95.0), it doesn't work anymore.

Can you please provide a solution to this issue?

Thanks in advance
