Firefox 技術支援討論區

Good day, A month ago my system froze. Firefox re-loaded and went back to a clean install with none of my settings saved. Managed to get it back to where I had it before with one exception: All of a sudden, when I try to log into certain web pages, even Amazon, I get this message:

Secure Connection Failed

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

However, if I log into the website using a VPN, I have no problem! Help! Thank you VERY MUCH! Pietro

The credit card autofill shows all the credit cards but when I click on any of them it does not autofill. Ive used this hundreds of times before and it worked fine. I never changed any settings and the autofill setting is on.

Please help!

When I open https://www.washingtonpost.com/ it loads but after a few seconds it goes blank. This started a few days ago and only happens on firefox.

I have tried the scaling options and it makes no difference. For PDF files, I save them. For webpages, I need to workaround and use Edge or Print Screen and past into a Word document.

I am newly running Windows 10 and reinstalled my printer drivers for HP 4520.

Thank you.

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

Can someone confirm if mozilla-api[.]com is an official Mozilla domain? It was registered 7 months ago with Namecheap registrar. I am unable to find any overlap with official Mozilla infrastructure and I suspect this is a malicious domain.

Hello, I use a website, MySubaru.com, that has always loaded on my iMac (10.12). Lately what I get is a blank screen whether from the bookmark or the website in Google. Strangely enough, the site loads fine using Safari and on my MacBook and iPhone. Any suggestions? Thank you, Eric

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

I've always used Firefox as my default web browser. Now that Microsoft Edge got loaded onto my PC I can't access a lot of my bookmarks through Firefox. I get an "access denied" response. I've tried removing MS Edge but it won't let me. Is there a fix for this problem? How do I remove MS Edge? Any assistance is greatly appreciated. Thank You. Dale P.

Is Firefox will support this feature ? Or at which version will support ?

File System Access API

I can no longer print from firefox. The final print always comes out 1/5 +- size and is unreadable. It doesnt matter what king of a document it is and if I go to chrome or edge it prints fine. This began occurring I believe after the last version.

Hello team,

I'm not sure what happened, but I was not able to open Firefox after restarting my PC. I currently run Windows 11 on a fully upgraded rig.

Up until today, I have been trouble free. Error 1: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I tried several options - and have been googling/trying several steps for a couple of hours (after each step, I restarted the PC):

1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Attempted to use Command Lines to open Firefox https://wiki.mozilla.org/Firefox/CommandLineOptions 3. Opened Profile Manager and attempted to create a new profile - when I did this the new profile would not display in the Profile Manager, but it would display in the Profiles folder under Appdata [I tried this multiple times] 4. Deleted the profiles.ini file

After deleting the .ini file Error 2: "Your Firefox profile cannot be loaded. It may be missing or inaccessible." 1. Uninstalled and then Reinstalled a fresh copy of Mozilla 2. Opened Profile Manager and attempted to create a new profile. After following the Profile Wizard, another error pops up: "An unexpected error has prevented your changes from being saved."

I am completely stumped. I hope you can help, Sean

On the messenger thing on facebook I'm not getting sound alerts when someone sends me a message. It works with the chrome browser though, so it won't be settings on facebook. Any settings anywhere I can change?

There are a number of old threads regarding this and having worked through them it is still unresolved. 1) I have cleared cache/cookies 2) I have disabled all extensions 3) I have turned off tracking 4) I have tried in safe mode - still the same.

This is not just on one website - it is on ALL that have Facebook feeds. It is NOT just on my laptop - I have asked others to try - they have the same result - blank page. ...so please don't suggest re-installing Firefox!!

An example is: https://dragonsdensoftplay.co.uk/News-Events/news-events.html

The feed works ok in other browsers.

Thank you

For at least the last few months, I've been having problems with printing. It doesn't matter if it's a web page, an attachment in yahoo.mail or a return label from Amazon, the print is too big to fit on the paper. If I switch to Edge, it comes out fine. I have used Firefox for years and never had this problem till now. Please help.
