Firefox 技術支援討論區

After the most recent update to the browser, I am no longer able to successfully login to many websites. Example for me include: Xcel Energy, Aol Mail, my local City Utility website and no doubt others I have yet to discover.

I know this is a browser dependent issue because Google Chrome is still able to access these sites just fine, but after the latest update to Firefox it no longer can.

It's able to load the login page and the site, but login in specifically returns either an error that shows on the webpage, or the URL displays some form of error code. Or in AOLs case it simply says "Uh oh. Looks like something went wrong. Please try again later." with a length authorization error code in the URL.

Any help with this would be appreciated. I've cleared Cookies, Cache, Active Logins and every other History Clearing option set to "Everything" as the length of time back to clean-up.

Like I said, this is a Firefox dependent issue due to Chrome accessing these sites just fine. I'd rather stick with Firefox over moving to Chrome but if no one can solve this problem then I guess it'll finally be time to ditch Firefox sadly, even though I've been using it since the early 2010s.

I've noticed that when I download a PDF attachment or file firefox open the file on same tab instead of new tab.

How to I change settings to open pdf on new tab and not the same tab?

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

I am trying to transfer my bookmarks, open tabs and passwords etc. from my old laptop to my new one. It appears I have to do this with Firefox Sync under the preferences menu. However when I try to connect a new device, I am told to open the code scanner on my Firefox App, which sounds like I have to use a mobile? How do I scan the QR code using my new laptop?

I've noticed that some websites will endlessly spam the console (in developer tools) with rubbish, and I would like to be able to block that from happening. I'm ignorant about this sort of stuff in general, and it confuses me how a website can even access my browser's console to begin with.

The latest example I came across which caused me to finally ask about it, was some strange JavaScript spam with some kind of < div > (had to edit this with spaces to show it in the post) structure containing over a thousand characters. This entire thing gets spammed in the console at a rate of a few every second. I recorded a short gif of it, which imgur seems to have converted into a video: https://i.imgur.com/dosMZjo.mp4

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

Firefox on PC doesn't load any sites, not even 192.168.0.1. Not even in Troubleshoot Mode Yesterday it worked.

Firefox is the only browser with this issue. Chrome and Edge work fine

Firefox on my Android phone works fine as well

I tried following these articles but they didn't help:

https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites

YouTube TV won't load in my Mac OR my Windows Firefox.

Error: "Please use the latest version of Firefox to watch YouTube TV on your desktop."

I'm running 99.0.1. Enhanced tracking off. Extensions off.

YouTube support has been no help! Any ideas here?

Thank you.

My images look all glitched out and scrambled. It wasn't like this before, and I don't remember if I changed anything in my about:config.

I've included what they look like.

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.

OneDrive links recently stopped opening (browser tab shows the OneDrive icon but the page shows no content); Edge continues to open the links. I am running Firefox 99.0.1 (64 bit desktop).

Since the update that changed the cookie management, I have not been able to delete just my cache without losing all my cookies & login information. I'm no longer able to automatically sign into a bunch of my sites.

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

I see instructions for sync' to a phone, how do I initially (connect) sync to my desktop from my laptop?

When I sync my bookmarks, how does is know which computer is the primary (the one that I want to duplicate changes from)?

For example, I added new bookmarks and revised some old ones on my laptop and did not have the sync on my desktop at the same time. Now, if I sync my laptop to my desktop, how does it know which device is my primary (in this case my laptop) where I made all the changes?

My goal is to revise all the bookmarks currently on my desktop to reflect all the changes I made to them on my laptop. I'd like to do it without duplicates or displaying old desktop residual bookmarks that I deleted and/or modified on the laptop prior to sync to the desktop.

In this case, should I delete my bookmarks from my desktop and then sync to my laptop so as to seamlessly & efficiently have my bookmarks toolbar on the laptop look the same on the desktop?

Thank you for your help here! Christopher

Hi everyone,

Last Saturday, I was able to sign in to Firefox Add-Ons Firefox Add-Ons and submit a pre-release of an add-on I'm working on. But today, I'm being forced to enable 2FA to simply log in to the site. I don't want to enable 2FA, I just don't need it. Can someone explain me why is this happening ? Can I just log in and submit my add-on's update ?

I've tried to sign in two different MacBooks (M1 12.1 and Yosemite 10.10.5), using two different Firefox versions (99.0.1 and 78.15.0esr). Also, I haven't enabled 2FA in my personal account.

Thanks in advance.

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

When playing music on music.youtube.com, if I navigate away from the tab, by either moving to a different tab or opening a different application the music pauses. This happens consistently with two different Firefox profiles.

I admittedly have a quite a few plugins installed, so I tested this in a private window and this issue does not occur.

I attempted disabling the obvious plugins UBlock, 'I don't care about cookies', and Tampermonkey without any success. I also tried using a different user-agent without any success.
