Firefox Support Forum

Received this message thismorning while using my Ledger device:-

Something went wrong-U2F browser support is needed for Ledger. Please use Chrome, Opera or Firefox with a U2F extension. Also make sure you're on a HTTPS connection.

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

My Macbook Air is running iOS 10.12.6, so how am I meant to update Firefox, as the TSB bank says I must to use their online software? Firefox is apparently no longer supported below iOS 10.14. I can't upgrade my iOS. What do I do? I'm 75 years old and dont need all this!

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

Hi, I have been searching a way to change the Firefox new tab background image keeping its vanilla design. I found I could use a userContent.css file in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1271362] I have followed the instructions step by step but it doesn't currently work.

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

here's the video: https://youtu.be/qMY-38z_TC0

Since the latest version of firefox installed when I go to this site for my mail Firefox won't auto fill the email address. It won't display any of the users When you tab to the password field, the list appears but only populates the password field.

i need to know how to fix this The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (minecraft) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

so i can get this https://www.minecraft.net/en-us/marketplace/pdp?id=9a2fb0af-8f64-434a-8a37-3ba1a3664ed2#

I have A LOT of problems with FF since the last couples of updates. It started around two months ago and after one of the updates (and FF has constant updates which is pretty annoying) the browser immediately starting getting really slow and buggy. The browser keeps crashing constantly, is slow, loading websites end in "network cannot be found" notices and you need to reload pages all the time to get them to load, videos play in the background by themselves on saved tabs without being activated or started.... The redesign of the menu some time back, btw, have gone to worse as it's now more difficult to find the active tab than before.

I've followed all instructions to try and resolve it and nothing works. I have no virus or downloads on the system so this is not the cause. Plugins activated or not activated makes no difference. Changing settings in FF to whatever suggested makes no difference, using about: to change settings makes no difference.

The browser has really turned almost unusable.

Our organization recently upgraded everyone from standard Firefox to Firefox ESR 115

Several users continually get the following error:

XUL Runner

"This profile was last used with a newer version of this application. Please create a new profile.

Users are getting the error even after a new profile has been created.

We have tried uninstalling Firefox both through the Control Panel and using IO Bit uninstaller but the issue persists.

All users are running Windows 10 22H2 64 Bit

All YouTube videos get me the following page, none of them will load. If I open them in a private window, they load just fine. I've tried clearing cache, disabling hardware acceleration, resteing Firefox (only works for a day or two, then same issue) and nothing.

For the past few days the website 'dictionary.com' does not load on Firefox (I'm using a laptop with Windows 10). The screen reads "Unexpected Application Error! aN.findLast is not a function". I've deleted all cookies and caches, but the problem still is occurring. Help!

This is the same problem listed below. Recently upgraded to Ubuntu 22.04.3 LTS and Firefox 117.0 a few weeks ago and can't get the files to attach. In fact it won't open the file system. Tried removing all extensions as suggested and rebooting, but nothing changed.

Hi,

There is a feature my company has for biometric login that works on both chrome and safari (Mac m1 pro 14inch with Ventura 13.1). It says firefox doesn't support Fidoc2, but I believe it does. How would I debug this/get it to work.

Also how do I get biometrics to work for like passwords!

Not sure when it started but nearly every attempt to play Youtube videos results in the video freezing after about 1/2 second while audio continues, then the video jumps forward randomly before freezing again. Have reloaded, restarted, cleared history, cookies, etc, and nothing helps. Mean time Chrome plays the videos flawlessly. This is a recent problem with FF and needs fixing badly as it will just not go away.

I am using Firefox Nightly 119.0a1 (2023-09-04) on macOS 12.6.8 on an Intel 15' MBP.

When clicking on a link from an external app (eg. WhatsApp, Teams, etc.) with Firefox not running in the background, Firefox will open up but will not open the link. I have to go back to the app and click the link again for it to work.

This has been an issue for me for a while now and it only happens with Firefox as other browsers will work as expected.
