Hello all.. I have two network cards in my pc, each one from a different network. One network needs proxy and the other is a direct connection. I have always used two browsers, and firefox for the network with proxy, because it allows independent configuration. But a few months ago it is not assuming this configuration and it goes through the configuration of the operating system

How do I update my notification email address?

I am asking for this because I continue to receive notifications at my OLD email address, despite updating my profile to my NEW email address.

I updated from a Macbook Pro to a Macbook Air. Since then, Firefox doesn't work. I get the message:

HTTPS-Only Mode Alert Secure Site Not Available You've enabled HTTPS-Only Mode for enhanced security, and a HTTPS version of cbc.ca is not available. Learn More... What could be causing this? • Most likely, the website simply does not support HTTPS. • It's also possible that an attacker is involved. If you decide to visit the website, you should not enter any sensitive information like passwords, emails, or credit card details. If you continue, HTTPS-Only Mode will be turned off temporarily for this site. Continue to HTTP Site Go Back.

If I click on the Continue to HTTP Site button, I get this:

Secure Connection Failed An error occurred during a connection to www.cbc.ca. Peer's certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE • 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."

I've looked on the Privacy and Security page but can't find anything relevant, and I've looked on the Mozilla Troubleshooting page, as well. I also deleted the app and redownloaded it. I'm not an advanced user, so it's probable I've missed something. Thank you for your help.

I have a MAC studio computer with a 28 inch ASUS monitor. When I open Firefox it doesn't open fully to cover the entire screen. What settings need to be changed in order to correct this, so that when I open Firefox it covers the entire screen? Thanks Len

How can I get them back? Do you ever respond? How? Phone contact available? My cell: [removed phone# from public forum]

I used Chrome for ages, and migrated to Firefox. The spell check on Chrome has an option to give use the internet to offer suggestions on spelling corrections.

The option is now called "Enhanced Spell Check" and it states that it uses the same spell checker that's used in Google Search.

Something similar would be helpful in Firefox as the built in Spell Checker is rather lacking and seems to fail often on newer or more rarely used words. Sometimes it just completely fails.

For example: I wrote: "hipocritical" Firefox's suggestion: "theocracy" Chromes "enhanced" suggestion: 'hypocritical"

We are experiencing an issue with our web application... we do form action and iframe src changes dynamically with Javascript to redirect the user to different pages within our app.

We do so using relative paths, however although the website is loaded in HTTPS, "sometimes" when we do these changes in src, or action and then submit... Firefox seems to be changing the scheme protocol, from https to http, thus we are getting mixed content blocking.

But we are not really using mixed content... our calls do not include absolute URLs, so there should not be any mixed content issue.

This is an example of the change within the source of an iframe:

document.getElementById('piframe'+id).innerHTML='<iframe src="../fondo.html" id="ttab'+id+'" name="ttab'+id+'" width="100%" scrolling="auto" height="' + espacio_iframe+'" '+ scroll + ' frameborder="0"></iframe>'

And this is an example of what we do changing the action:

document.form1.action = '../'+url; document.form1.submit();

Both actions use relative paths... and both actions throw mixed content block.

This happens only with Firefox... what might be the cause?

Thanks for your help?

Hello Firefox Community,

I am a web developer, and I am writing to you regarding an issue I have encountered with the website "https://www.socialboothlv.com/". The problem I am facing is related to website responsiveness.

Upon reviewing the website, I noticed that it is not responsive to different screen sizes, particularly on mobile devices. This means that users accessing the site from their mobile devices may find it difficult to navigate and interact with the content. Are there any best practices or tools that I can use to improve the website's responsiveness?

Thank you for your help and support.

Best regards, M. Abdullah Khan

I recently downloaded Windows 11 and while using Firefox on my main display there is a noticable white line above the TaskBar. This doesnt happen in any other application nor does it happen on external displays, only on my main monitor. When pressing F11 it disappears.

Firefox will not operate "check out" on various shopping sites; I have to switch to another browser to do so. I wrote a book review on Audible, clicked "preview" and landed on a mostly blank page. All I could do was submit the review I couldn't see and hope all the time I'd put in wasn't wasted. This kind of thing--blank pages, frozen pages--happens frequently and irregularly. There's no way of knowing in advance what will happen and where. I refresh, clear cookies and cache--nothing makes any difference. Am I supposed to stay permanently in Troubleshoot mode (and is that even possible?) to make Firefox work the way it used to? Using Windows 11, 64-bit system.

I loaded Firefox on a new laptop and then synced my account. When I went to my desktop, my homepage with all my shortcuts had been synced to the blank homepage of the new installation of Firefox on the laptop. How do I prevent this and how do I force Firefox to sync a certain home page on all installations? I have another notebook with my old home page and would like to force that home page across all installations.

Hi,

I always restore my previous tabs and windows when opening Mozilla, and until recently Mozilla always remembered my scroll location in those tabs, which is very handy because I read books online and otherwise have no idea where in the book I was. It recently stopped doing that though, and I haven't found a way to fix it after Googling a bit. Does anyone know how I can get back to how it was before?

Thanks very much in advance!!

When I open Firefox, it doesn't open in full screen mode, instead, I have to hit the minimize/maximize button twice before it will enter full screen mode. This has happened before, went away and came back again

I have https://account.firefox.com in my password manager with the appropriate username (my email address) and password. At attempted login I find I must always type (or paste) my username. Autofill by my password manager is not accepted as on all other websites. Upon having so entered the userid, the password manager may then autofill the password as if this were a first-time visit to the website. Further, the login process demands verification via code sent to my email address. This happens over and over. It occurs no matter which browser I use: Firefox or Safari. This is entirely inefficient and encourages me NOT to bother with the website whatsoever!

I use a website for school that utilizes two factor authentication through a base site that then logins you in on that browser for a set amount of time. The problem I have is that on my Macbook pro the log in will not log me out of some sites and then it will log me out of other sites but then no longer load the log in screen on the laptop. Even if I do log in and clear all my cookies. I have all my security turned off so it isn't cross site cookies or a firewall blocking the site from loading. Please help. The site does work completely fine on my windows PC so I do not know if it is a mac issue or a Firefox issue
