Firefox Support Forum

When I type my website in the bar, firefox puts www in front of it, which causes the warning page: firefox detected a potential security threat and did not continue to www.karinchappell.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

If I remove the www by backspacing it, the page loads correctly.

I've checked the website: "SSL is enabled on your site, and an SSL certificate was detected on your site."

When I've asked around the techies I know, I've been told this is an antiquated way of dealing with it. Please advise.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

When clicking advanced button there is no way to proceed:

Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.google.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

Hello! Short story: I recently discovered that adding a new GIF image to a page resets the animations of existing GIF images on the page with the same src.

Expected behavior: Adding a new GIF image to the page should not reset the animation of existing images with same src.

Actual result: Adding a new GIF image to the page resets the animation of all existing GIF images on the page with same src.

Code with example: https://codesandbox.io/s/heuristic-platform-jsguir Video demo: https://www.youtube.com/watch?v=k-ZMrrqq_KI

Simplified version of the code showing unexpected behavior: https://codesandbox.io/s/elastic-shtern-vwrcx1

Does anyone know why this is happening? Is this a bug?

Browser: Firefox Developer Edition 102.0b4 (64-bit) OS: Windows 11

It seems that since the last update none of the available screen schemes / contrast schemes allow for me to see the input mask boxes. (Of course today with this support page there is an exception but....) I have wasted hours trying to read and adjust and end with only an attitude. HELP

I am unable to browse to onedrive.live.com or onedrive.com in Firefox. Works in all other browsers on my machine (Windows 10 - works in Chrome, Edge, Vivaldi, Opera) but just shows a blank page in Firefox.

I've tried in various locations, so it's not my connection. I am running the latest version of Firefox (102.0 64 bit)

Hello,

I lost my bookmarks when I changed my password. Can Firefox recover them on its servers? I've seen many similar complaints arising from similar problems. One would think that Firefox would address this issue to improve the user experience.

Hi,

I am unable to use the screenshot feature since the update to 102.0 and I don't know why. So far it always worked. I have updated the screenshot item via customizing the toolbar, still it does not respond.

Have you got a solution that works?

Thank you.

Sincerely,

If I downloaded a picture. from Save a link as. And no. Save image as.

But the image goes down in my file.  png.  To the personal computer.  

In a standard photo gallery.

This means that the image was saved on my computer without a link from the Internet. 
And she will be with me permanently.

Or she's still on the link from online.  And when as it is link be deleted from the Internet.
this images will be deleted by my gallery.  Just opened for see in photo gallery pc.

 an important question.  Because I kept a lot of pictures like that.

i get 'server not found' and 'try again' window when trying to access sites and even within sites if i manage to get on - after several 'try again' clicks

could this be related to recently installed fibre optics or do i have a virus - my anti-virus protection is bitdefenders

When I open a new tab, I'd like Firefox to show pages that I've saved to Pocket.

I have selected Settings >> Home >> Firefox Home Content >> Recent Activity >> "Pages Saved to Pocket".

This worked pretty well! So well that I upgraded to Pocket premium! Unfortunately, I no longer see any of the pages I've saved to pocket.

How can I get my saved pages back? Thanks!

Hi there,

I would like the option "Delete cookies and site data when Firefox is closed" to be enabled, but it appears that Firefox is actively undoing this change. If I go into settings and check this box, it will appear to be successful and remain checked until that session is over, but if I close & restart, the box is always unchecked after restarting. Is this a bug in the build of Firefox I'm running (102), or is this behavior intended?

Thank you!

I turned on my computer like any other normal day this morning, except when I launched firefox it was like it was freshly installed, all my passwords, usernames, cookies, saved bookmarks, work related history material is all GONE it's like I just installed firefox for the first time. A lot of these passwords I dont know off the top of my head so I'm going to have to ask my business partners for ALL the passwords... Why did firefox do this? What is the problem??

Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

Why I can't get on webpage Doddrv.com.

403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. Thank you for your time

Why do I get " 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied." when I try an access doddrv.com?

My desktop icon gave me a bad link error message, what happened to my forefox account? I upgraded, checked the save settings, and EVERYTHING is gone. All of my saved logins for several hundred sites. How can I restore them?
