Within 24 hours this weekend I was notified by my anti virus application (Avast) that they are no longer supporting Firefox browser (to concentrate on Outlook and Chrome), and a political news website that I frequent (Meidas) blocked me with a "captcha" type puzzle. The website said my browser was mimicking robot or bot use. I was presented with a puzzle requiring me to slide a tab rightward. It repeatedly told me I had slid the tab incorrectly. I believe all of this happened after an update of Firefox about the middle of last week.

Running under latest Windows 11 Firefox 126.0 will not start unless I click Run as Administrator. I changed permission for my User acct in Firefox to Full since I am the administrator but the problem persists

So within the past couple of days my twitter/x display setting suddenly switched to "Lights out" from "Default". I can reset it in t/x settings but if I close my browser it resets back to "Lights out" on reopen.

However, this same change happened with other browsers chrome and brave, but if I reset it on t/x it remains changed for those browsers if I close them and reopen.

When I say close I do not mean just that window/tab. I mean close the browser completely and restart it.

What do I need to do to get FF to retain this t/x setting?

I'm experiencing an issue, when I visit this website in Firefox, some images appear broken, but they display perfectly in other browsers. Has anyone else encountered this problem or have any suggestions on how to fix it?

I have two monitors; I keep my taskbar on the right monitor and run Firefox on the left monitor. For some reason, whenever Firefox gets minimized, the window moves to whichever monitor the taskbar is on (I've done some testing to confirm it is specifically the monitor the task bar is on). Because I also run a program called max.to to separate my right monitor into different sections, this action of minimizing to, and restoring to, the wrong monitor is also resizing my Firefox window.

Is there any way, any option I've overlooked, that would get Firefox to minimize and restore to whichever monitor is is actually running on?

I've attached an image that shows, as best I can get it, the window moving over to the task bar monitor when minimizing.

Hello, Mozilla Community Hope you doing well, I'm contacting you to ask for help with a Mozilla Firefox problem I'm having with trying to visit the following website: Geometry Spot Games: https://geometryspot.com/ It won't load, and I'm not sure if that's because of a bug in the website, a browser issue, or something else entirely.

Does anyone else have knowledge of this problem or recommendations for a fix? I've attempted removing addons and cleaning the cache in my browser, but the issue still exists.

I would be grateful for any advice or ideas on improving the usability of the website. Thank you in advance for your assistance.

I have Firefox running on Screen #3. The website that I use with my radiology clients opens popups and I want these to open on Screen #3 as well. However, they are opening on Screening #1. How can I get them to open on Screen #3?

Thank you.

Is there any way to block media mini players from popping up on websites entirely?

This is what I've tried, I found this in another article here.

   media.autoplay.default = 5 [0:allow;1:blockAudible;5:blockAll]
   media.autoplay.blocking_policy = 2
   media.autoplay.allow-extension-background-pages = false
   media.autoplay.block-event.enabled = true
   media.block-autoplay-until-in-foreground 

It doesn't autoplay anymore, but it still pops up in the bottom right corner of the screen. I don't mean Firefox's picture in picture, I'm talking about the floating mini player most websites use. It's thoroughly annoying, especially when you have your pop-up settings set to off.

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

Why is the text in tab names, address bar and menu boxes so small? I did the changes to about:config and the other one that comes up when I googled this question but, while they enlarge the text in those places, they make the page content too big.

After I boot my computer, I can access any of the sites I usually use, but only once. If I then close the site and attempt to open it again (or to open any of the other affected sites), I get the following message: " Secure Connection Failed

An error occurred during a connection to phoenixcommons.cohousing.site. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

The site shown in the error message above is the one I most ofen use, but other very common sites (e.g. Google.com) exhibit the same problem:

" Secure Connection Failed

An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

Yeah, right. I'm supposed to contact Alphabet and inform of the problem?

In contrast, some sites (e.g. The New York Times, The Washington Post) are not affected.

I can paste affected URLs into another browser (I used Brave) and access them with no problems.

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

I have to configure a lot of networking equipment! One day I might be working on a brand new piece of equipment and the next day trying to log into some ancient piece of equipment because I need to change something and I can't replace it yet. I'm having a major issue with the redirect even if I explicitly type HTTP it forces it to HTTPS ( and no I don't have HTTPS everywhere installed I've actually never used it ). I've noticed recently a few updates back now that if the connection cannot succeed it redirects to HTTP but it can hang up in a weird limbo where it thinks the site doesn't exist. There needs to be a toggle for local addresses explicitly typed "HTTP" to try that first. There also needs a toggle to ignore the security issues when accessing the device with a self assigned certificate as every single networking device has a self assigned a certificate and every time I need to change the setting on a router I have to agree even though I have a greed for the last 10 times when I've access the device or I just reset the device and the self signed certificate changed. And I don't know how you're gonna handle this on mobile but it almost makes using a mobile browser useless because I might as well just get the computer out even if all I have to do is change a password, SSID or just check a setting.

So local addresses need an option to lower the warning level for self signed certificates and to obey the typed protocol!

And there's some sort of bug with the Logic that detects a certificate or non-secure site that breaks when the connection drops. The only way I've been able to get around this is to go to the address bar and hit enter as a reload will not work and a reload skipping cash will not work to bring the site back up.

I've had devices that I thought weren't working only to find out they were working fine after 3 or 4 attempts and restarts only to find it's just that firefox thought the site didn't exist anymore.

And I don't have any other options because chrome is even worse with HTTPS once it gets it's vampire fangs in you're stuck it will not let you go back. And safari you might as will be undead.

Finally getting annoyed enough to write some thing as every time you go change your setting reboot device check setting log back in change saying restart log back in and you have to hit except certificate every single time.

And while I'm here Bring back the checkbox to save/ not save the certificate as I might not want to save the certificate when I know I'm going to reset the device and it's going to be totally different in the next 10 minutes. Or I might not want to save it at all like I go to a website that's misconfigured and the certificates not valid for the domain name that it's using.

Hello,

My protonpass manager and email accounts were compromised by a hacked Discord user. I began setting up the password manager in mozilla to help me with my passwords, but somehow mistyped the Master Password I was trying to set up. Now I have no idea what it is and need to reset it.

Thank you,

I am trying to sync to computers to the same firefox, bookmarks, passwords etc.
