Firefox Support Forum

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open.

This problem only occurs when using Firefox. If using Microsoft's browser there is no problem.

Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years.

I prefer the Firefox browser versus Microsoft. Please research and repair this issue.

Accidentally closed browser with many multiple tabs open. Tried to restore history but option was grayed out. Tried several times but was not able to get back to the original browsing window with the multiple open tabs.

Would really appreciate help on this, if possible, as the many multiple tabs contained family history research that will be difficult to impossible to duplicate.

Thank you.

Firefox decided to remove the total amount of homepage shortcuts. For months, it allowed for 4 rows and 8 columns, with blank "Add Shortcut" shortcuts. This allowed me to organize or split my shortcuts better. This morning, it decided to move all shortcuts together. As per the "Before" and "After" screenshots attached.

Usual disclaimers: Firefox 125.0.1 (64-bit) on Windows 10 No Config edits No extensions currently installed manipulate, affect or otherwise influence shortcuts

Please advise.

Windows 11 Firefox browser 125.0.1

In Proton Mail, when I receive an email with an picture attached inline, I get the following error message: "Your browser could not verify the remote server's identity. The image might be hosted using the http protocol." Is this issue with settings in Proton or Firefox? How do I fix this? See image below. Thank you.

Hi there, my name is Alvimutmex. Every time a webpage loads with the Mozilla browser, a "not supported" message appears. Upon examining the settings, I found that Mozilla has to be updated. Would you kindly assist me with updating Mozilla? For example, I receive an error notification when I try to open (https://pdfmedicalbooks.com/).

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

i am using firefox developer edition version 126.0b3 (64-bit) on linux mint with an x11 desktop and for some reason the drag and drop breaks frequently.

i think i have figured out how i can consistently recreate the bug as well as sort of fix it temporarily.

i start with a newly launched browser. everything works fine. but then if i attempt to drag and drop something shortly after i drag and dropped something else and it did the little animation where it returns to its original position, i find that i cant drag and drop anything FROM firefox to anywhere else. and i also cannot rearrage tabs.

it seems to fix itself whenever I drag something from another program TO firefox successfully such as text into a textbox, or a .html file into the window to view it.

The comment windows are present but do not function. The youtube hosts are accepting comments from other folks. I wonder if some Firefox settings need adjustment so I can participate. If you reply I hope it goes straight to my email address as I nmay not find this site easily/again.

Please see the attached screenshot. I get this popup EVERY TIME I open FireFox. I've tried a number of different suggested "fixes" from Google Searches with no success.

I want this popup GONE.

Starting Friday April 19, I have been experiencing constant very brief internet outages/reconnections while using Facebook on the desktop. The outages do not occur anywhere else on the internet...and do not occur on other browsers. I prefer to use Firefox. I am using Windows 11.

I keep getting this message every time I try to access a website I haven't accessed for a while : see attached graphic.

How can I get this to stop ?

Is it possible to import bookmarks for a different Mozilla account. Apparently I have 2 different Mozilla accounts. I had been using (I'll call it account #1) for quite a while, and recently subscribed to Mozilla VPN service. When I subscribed i gave it login info for "Account #2". How can I keep the logon info for the VPN, and get my bookmarks imported from the old (routinely used account #1) ? Or, can I change the VPN service to the old account (account #1)? I know how to add another device to the VPN account, but the "accounts" are on the same "device".

Thanks...

Almost every time that I open a new session of Firefox I get a message that there is a problem and it needs a refresh, which removes the extension I use all the time. Any ideas why this keeps happening over and over and what I might to resolve the problem?

this was asked before by myself

/questions/1284841

and again by another user

/questions/1402855

the code was

1. navigator-toolbox {

 max-height: 0;
 overflow: hidden;
 transition: ease all 3s;

}

1. main-window:hover #navigator-toolbox {

 max-height: 100vh;
 animation: 0s pop-in;
 animation-fill-mode: both;
 animation-delay: 2s;

}

@keyframes pop-in {

 from {overflow: hidden}
 to {overflow: unset}

}

the issue now i have with firefox 124.0.2 is that the transition is now instant when my mouse enters or leaves the window and one of my addon buttons (roboform) no longer works with this userchrome.css edit.

its been a few updates ago it broke maybe 15 or so and now im wondering if there is a better updated script that works like it used to.

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.
