Firefox Community Forum

Hi, I'm trying to pair my devices but it gets to the authenticator step but doesn't say which authenticator it needs. Is there another step I should be taking? Lou

I started noticing that Firefox was giving me a lot of "not responding" freezes the past couple of weeks. The past couple of days I basically cannot access Firefox at all - constant, immediate freezing. I have tried uninstalling/reinstalling (multiple times), disabling hardware acceleration, running troubleshooter mode (still freezes! if it opens at all!), deleting profiles, restarting my computer, etc. I've done just about everything I can find online about this issue. Nothing has worked. I have no issues with Chrome or Edge.

Any suggestions??

I set value to true to disable IPv6 and it worked for some websites, but not all. Works fine in Opera browser. Further corrections are more technical than I can handle. What should I do? I turned on logging, but don't know how to upload it.

Kept getting messages that Firefox is unresponsive during use. Has now stopped all together. Uninstalled and reloaded, got a welcome to Firefox message then it went unresponsive again. Now a double click on the App to start does nothing.

I want to clear the cache on this laptop that has been in storage for months, but I can't get the instructions question lines to respond when I check the boxes ??? What am i missing?

I am using Firefox 155.01 on MacBook Air (M1).

I updated to OS 27.0 yesterday.

I have tracking protection set to Standard (same as before the software update).

Websites I need to use frequently, such as my health care provider, just twirl, will not open.

I've seen this on a few sites and it sounds like this person also experienced this. It happens on Linux and Window. I don't think it's a new bug/behavior.

I'll use vanguard.com as an example.

1. Visit investor.vanguard.com site. Click that you'd like to log on. 2. I'll be placed on a login.vanguard.com page that displays a Username field and a Password field. Because I've logged in before, those fields are yellow and filled in with the proper values. (In the case of the password field, it's all stars, but when I click to reveal the password, it's the correct password.) 3. Click on the "Log In". 4. The browser rerenders the page claiming that the userid or password is wrong.

But if I follow the above steps, but add a step:

2.5. I slightly edit both (one is not sufficient) fields, removing a character and putting it back in so the values are edited but not changed. As I do this the fields become white instead of yellow.

Now when I reach step (4), I'm actually logged in without complaints.

The underlying AJAX request is pretty cryptic, so I can't quickly spot/debug what happens at that level, but I assume the page is not passing the field values visible as yellow. on the page.

Am I misunderstanding how the yellow auto-fill works? (On most sites it works as I expected and no reediting the autofilled fields is necessary.)

Can this be fixed or should I put up with it?

I created a Gmail account so I could use it to sync my mozilla browser but I tried to you it too quickly and it was temporarily blocked by google.

I submitted an appeal and they unblocked it, but since then I have been unable to receive any verification codes that are sent to that email address.

I assume it's on some kind of list that is suppressing being able to send to it.

I’m experiencing a strange issue on Firefox where a separate blank/dark window briefly appears over the browser while I’m browsing, then disappears.

The window appears to have the Firefox icon in the top-left and what looks like a Firefox tab/address-bar interface, but there is no visible text or error message.

It happens randomly while Firefox is open, including while watching YouTube. It does not appear when Firefox is closed.

Troubleshooting already performed:

• Windows 11 cloud reinstall using Remove everything
• New Microsoft account
• Defender Offline scan clean
• Multiple malware scanners clean
• Malwarebytes Premium installed
• uBlock Origin (only extension i use) removed/tested, but the issue remained

I took a picture showing the window appearing. Is this a known Firefox issue, background Firefox process, or something else?

Issue occurred on September 6:When I was running a game and updated my graphics card driver, Firefox was running in the background. My PC went completely black and became unresponsive, so I had to force‑restart the computer.

After rebooting, Firefox reverted to a brand‑new fresh‑install state. All my browser settings, login status, local profiles, browsing sessions, hundreds of open tabs and my categorized tab groups disappeared, only the welcome startup guide showed up.

I logged into my Mozilla account on my Android Firefox device. Some browsing history was synced back. However, synced history cannot restore the original tab session back‑forward page history, nor my manually sorted tab groups. All browser preferences, theme and language settings are also lost.

I originally had 4 separate local Firefox profiles on this Windows computer, isolated from each other for different work purposes. Only one profile was logged‑in to my Mozilla account and could partially sync data. The other three local profiles are completely gone. Those extra local profiles were NOT signed into any Mozilla account and were never synced to cloud storage.

In my Mozilla account’s connected devices list, there are two entries both belonging to this same computer: “MARSHAKK” and “Firefox by Administrator on MARSHAKK”, which correspond to my Firefox instance before and after the crash.

I cannot understand the community help articles about session recovery, and I’m unable to locate or restore my old local Firefox profiles and lost tab sessions by myself. Please give me assistance.

Firefox is showing me an older version of a website. When I'm opening the same site in other browser it is changes, but mozilla is still showing me previous version. what should I do to fix it?

I've been a user of Firefox for many, many years but I think I'm ready to switch to another browser. Every time Firefox updates, it deposits a shortcut on my desktop that I have to delete. I already have it installed in my start toolbar so I do not need it on my desktop. People will say "no big deal, just delete it" That is my point, I shouldn't have to, give me the option in Settings to install it or not.

I'm finding more and more sites no longer work using Firefox. I've confirmed all software is up to date, and tried different settings such as turning off ad , tracker and fingerprinting protections, but nothing works. Even sites at which I have an account have stopped working. Sometimes I can still log in to the account, on others I can't even do that. If I can log in, using the account for what it's intended such as searching for and saving lists of things or following links to saved items doesn't work. I value Firefox for it's security and privacy features, and being able to sync saved information in the account and across devices, but if a site won't all that benefit disappears.
