Firefox autofill always fills my phone number as +!(xxx)xxx-xxxx, despite most forms not accepting the country code. I have tried to remove it in the saved autofill address, but it keeps putting it back in. This makes the autofill not work. Why can I not disable this!?!?!?!

All of a sudden, when I hover over a tab, a small window of the web site that tab is in, appears. Never happened before.

I did go into Performance Options - Visual Effects and unchecked "enable peek," but it didn't work.

How do I stop these windows from appearing?

Windows 10.

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

Firefox (129.0.2) displays "401 - Unauthorized: Access is denied due to invalid credentials" (see attached image)

I have tried various combinations of setting and not setting the following in Firefox:

• network.negotiate-auth.trusted-uris
• network.negotiate-auth.delegation-uris
• network.auth.use-sspi

For the URI settings I have tried both .domainname.domainextension and https://servicename.domainname.domainextension

In Windows 10 Control Panel -> Internet Options, the site is in "Trusted sites" using a domain wildcard, and also "Local intranet" and both "Automatic logon" and "Enable Integrated Windows Authentication" are enabled. I suspect those setting aren't relevant since other browsers are authenticating without error or prompt, but calling this out to show that I've covered that base.

The web service is served by IIS 10.0 on Windows Server 2022 and the authentication provider list only includes Negotiate, but I don't believe this issue has anything to do with IIS or its configuration as, again, other browsers are authenticating without error or prompt.

Anything else to check?

Thank you for any guidance you can offer.

I have been running into issues if Firefox affecting other programs. One example - closing a game from the big fish game manager. Normal termination of the game hangs up. Closing firefox, usually via the windows task manager, frees up the game manager and the game properly terminates. However, before having task manager close firefox, I see a number anywhere from 6 to 12 or more - firefox(10) for example - trying to re-launch firefox gets an endless round of messages about firefox not responding and a request to close firefox. So far I have only found one effective workaround to this issue. Booting into safe mode and clearing temp and prefetch. This usually holds but I have been seeing this every day for the last 4 days. What is going on and how do I fix it?

I am unable to login to Spectrum.net. I was able to login until a couple of days ago. I can login through Edge but I don't want to use Edge. I contacted Spectrum and since I can log in through edge they say it is a browser problem.

Hi, I try to visit my website ahsapsaksi.com. When I visit on firefox(Desktop and ios). I see the isimtescil template which is the old version of the website. However when I access from another browser like opera I see the updated website(welcome to acme page) only with VPN connection. I tried to delete cookies, visited in private tab etc., however I couldn't manage to see my updated website in firefox(in both desktop and ios).

Can you help me please?

Now a new update. When I visit the website on firefox with VPN connection, I saw the updated version, and from now on I cannot see the website without the VPN at all. I dont understand what is going on. But I tried to clear that cookie many times. Now it looks like the cookie is deleted not by deleting in the settings but using VPN. Now the problem is I cannot visit the website without VPN. Can you explain my experience? why did it happen?

I've been experiencing issues with my firefox browser (most updated version 129.0.2, running on Mac Sonoma 14.6.1). Seemingly at random times, it decides to start displaying weird symbols all over. The settings, the menu, the text on webpages, it all reverts to these weird symbols. Restarting the app and my laptop works sometimes, but only for a little bit of time then a day or two later this starts to happen again. I've tried to look at other help articles but it doesn't seem to be a font thing, it's becoming really frustrating and I hope there's an easy fix otherwise I won't be able to keep using this browser as I share my screen for work often.

This is what sows when i try to get newsmax.com I tired newsmax.com but get the same message as below.

I always been able to connect w/newsmax.com - until now. When it does not connect tells me to contact that site. Well... I tried and I can not get in to let them know. How do I fix this problem? Thank you in advance for your assistance and reply. Sandra

When using the Firefox browser I find that You Tube videos freeze up after a short while, and the whole website becomes unresponsive. I do not have this problem if I use the Chrome browser, so apparently the problem is specific to the Firefox browser.

I switched to Firefox from Chrome recently. When I attempted to login to Facebook using Firefox, I got a message that FB had deleted my account for violating community standards. However, my FB account is still active and accessible when I log in using Chrome. I deleted Firefox, then reinstalled it, but I still get the same message about FB on Firefox -- that my account has been deleted. Can anyone help?

Working on an iMac:

Yesterday, the Firefox browser started running insanely slow. So slow that we couldn't begin to use it anymore. We had to reinstall the Firefox browser a few times to get it working again.

Also, the Firefox Dev Edition browser, randomly crashed. Since then, it hasn't opened once for me. I've reinstalled the browser multiple times. Each time I attempt to open it, nothing happens, so we have to force close it.

Have a new 2024 macbook pro m3 max with 128GB internal memory, 8tb ssd, macos (meest recente update) , and glass fibre internet connection of 1gb up and 1gb down and have used the same router and same ISP.

i use firefox in combination with nordvpn and multicontainer add-on to open multiple tabs with on each tab/containter the same video stream of 720p/3mb. Used to work perfect until a few weeks ago. In the beginning there is no problem, but after a while stream start to stutter and freezes completely and i get a blackscreen;. Tried every quick fix on the internet, and even increased the cache. Also tried different machines and issue is the same on each macos device.

how can i fix this?

Many thanks for looking into this.
