Firefox 社群討論區

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

I have downloaded and installed Mozilla Firefox on a new computer through the Edge browser both from the Mozilla site and through the Microsoft store. The installation downloads and installs as it should. Firefox has been selected as the default browser and everything appears as it should. When I open Firefox and type in an address, nothing populates. No site will open on the screen. When I open settings in Firefox, nothing opens. When I open history, it shows that I have been to the sites that I have loaded even though they haven't shown on the browser. I have completely uninstalled Firefox and reinstalled it with the same result. I have downloaded Opera browser and it installs correctly, I have downloaded and installed Firefox from Opera and had the same result. Any ideas?

Thanks, John

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

I Have Had It Installed On Microsoft Edge For About A Year With No Problems. I Had It Installed For About 3 Months On Firefox Then I Needed To Install It Again & I Get The Above Messages. Why Is It Doing This? There Hasn't Been Any Harm Done To My Computer. Also Firefox Needs A Customer Service Phone Number For People To Call & Explain Their Issues It's A Lot Quicker & Easier To Solve Your Problem.

I am a web dev and have a user download link to an excel xlsx file. On my own system it downloads fine in Chrome but in firefox ot displays the raw contents. Is this a FF setting?

I just got this new computer and want to transfer my FireFox bookmarks and history to it. I cannot access my old account because I do not have access to that email anymore, and you require me to get a code sent to that email to log in. That is still on my old computer that was originally running Windows 8, and has been deteriorating ever since Microsoft jammed Windows 10 down it's throat.

I might still be able to export the bookmarks if there is some way to do that.

The best way would be if I could access to that old account without needing to access bonin006@umn.edu my current email is wayne@nano-dyne.com

Please see if there is a way to help me.

Thanks, Wayne Bonin

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

So, I installed a new hard drive about a week ago and while re-installing things I also re-installed the Firefox Browser 64- bit. Strangely, it seems like the files did not install itself in the right areas or the files installed did not install themself in the right or normal places. It does work, but for some reason I don't see it's program files? Is this normal or something that happens?

Anyways, I've backed-up my bookmarks, and I am going to uninstall it, re-boot, and re-install it and see what happens I guess. Or should I uninstall Firefox and its Profile Folders also, etc, and than re-install it?

Firefox cannot access my bank account. Bank says hello to my name when I log in, but then keeps saying "loading" and can never show me what is in my bank accounts. Why?

I have an older piece of equipment that I need to communicate with it and the 232 interface will only work through Firefox. I was told I can downgrade the current version to 3.0, which is what I need, but I cannot find out how. HELP

I reinstalled Windows because my Windows got basically completely corrupted, I tried to log in to Firefox after reinstalling and it won't retrieve the bookmarks I had until 15 or 16 June, please help I can't get them back

Tēnā koutou (Hello everyone),

I deleted Firefox to re-install it after playing with profiles and that not working how I wanted it to (yet). I uninstalled the app from the applications and the library on my Mac and reinstalled Firefox. Now when I open Firefox it says that it's up and running but no windows actually open up for me. I have uninstalled and reinstalled it again and it still won't open windows. I have to force quit Firefox as nothing shows up in my top tool bar to even show Firefox as open.

How can I get Firefox to actually install and be functioning on my computer again?

Running (as of an hour ago) macOS 14.5 (was using previous up to date OS when I installed Firefox again.

TIA

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.
