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

I reset the laptop and lost the bookmarks. It originally reset to Edge but I downloaded Firefox. I have gone to the square of horizontal lines, clicked on Bookmarks, Manage Bookmarks, Import and Backup, Restore. The only date that shows is today's date. What else can I try?

volume and sound will not work since latest updates 102.00. you tube videos and others will not play sound. Only found solution to uninstall and reinstall but still after some week same error occur.

On a website I regularly visit Firefox does not know what to do with an mp3 link and will not prompt for an action.

How can I add MP3 to application list?

Copy of application list attached.

I try to log in into sync on fresh new laptop after downloading browser, so it has no extensions. It is stuck on login page with 'working' on login endlessly. It shows following error in the console:

refreshing and reinstalling did no good, and older pc on the same network logs in to sync perfectly.

all of my devices are on the latest update as of today.

My Iphone can send tabs to firefox on my Macbook. After hitting send, it takes 2-3 seconds for the mac to open the new tab.

However, when I send a tab from my macbook to iphone, it does not work.

all devices are connected on the same network.

I have When you open a link, image or media in a new tab, switch to it immediately" selected, but it doesn't go there when I do select a result from DuckDuckGo or Google. I need to right click my mouse and select "Open Link in new tab". How do I make this happen?

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.

Firefox V102(64) Win10 Hardware Acceleration off. Freezes sometimes after several hours, sometimes after 5 minutes even while one tab is working, no other tabs work. Task Manager to turn off Firefox. Main tabs https://www.kadaza.com, Fox News, YouTube, and business websites. Sometimes ESPN.

Lastest update did not fix.

When trying to save PDF's, firefox use to save each file as ex/ document, document(1), document(2) etc... now when trying to auto save it is making me input a name manually and won't automatically add the (#) to each file. How can i fix this? Thanks in advance.

Hello! Hoping someone can help with this new (to me) issue. I've searched and can't seem to find any articles/threads.

When I open the wifi menu on my laptop, I also see a media player featuring a video I watched three days ago (image attached). I've used my computer several times since then and didn't notice it. It also doesn't appear to be functional, as when I click play, nothing happens.

Is there a setting I'm missing to get this to go away and to prevent it from coming back again?

Thanks in advance!

I've been noticing this more and more recently. I'm using Firefox 102.0 on a Mac running Monterey (12.4) with 64GB RAM. Firefox will suddenly zoom up on a screen between 400% up to 800% (I'm guessing; no way to verify this): see screenshot. This happens on random pages without my hitting any keys or clicking on anything, and I cannot replicate it. Note that I do not have screen zoom engaged, nor do I have any sort of zoom mechanism turned on in the OS. Hitting "undo" does nothing, as the browser thinks I'm trying to undo an action on the page, not a zoom. Resetting Firefox or restarting makes no difference.

Note that the screenshot is at actual size, but I have no way to control the resolution at which it shows up for you.

This fonts.googleapis.com script freezes Firefox and it doesn't matter how long I wait it doesn't run again unless I restart my laptop. How can I fix it or block it? Thanks.

Whenever I try to full screen a video the first time I open the browser, the video will not completely fill the screen. It only happens on firefox and the first time I open the browser. I thought it was my extensions but it was not that. A thread was created on reddit describing the problem I have. I have linked it here. https://www.reddit.com/r/firefox/comments/rhwuvz/firefox_full_screen_on_win11_always_leaves_some/ I tried to change themes and that also did not work. Not sure what the problem is. Please help.

Hello,

I've recently encountered a curious issue with my Firefox browser (Firefox version 102.0, Windows 11 Insider Preview 10.0.25145.1011). At seemingly random times it will freeze for between two and five minutes (roughly). UI elements become completely unresponsive and the cursor does not update when moving over the browser window. The window will not minimize. Yet, Windows Task Manager does not report the application as being unresponsive. While never a common problem, any freezes in the past would eventually cause the Windows Task Manager to identify it as unresponsive.

I have disabled "recommended performance settings" and hardware acceleration to no avail. Everything seems perfectly normal immediately before and after the freezes, and I've yet to identify how I can trigger them. I do not recall having made any changes to my browser before the freezes started occurring, though multiple Windows updates have taken place since then. If I'm too impatient to wait I will end the Firefox processes via Windows Task Manager and restart it so I can return to my tabs without having cookies deleted. I have 13 plugins mainly covering privacy/security concerns. Is there some sort of debug tool I can engage to see what's occupying Firefox while it's frozen? I've just found the Firefox Task Manager, and will see if it can offer any additional information during/after the freezes.

Thanks, Logan

Hi All,

My outlook is suddenly not working properly on Firefox. It keeps lagging and freezing. I tried refreshing Firefox and clearing cache but with no use. Can anyone advise please?

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

I have no problems with chrome but when I pull up some of the websites that have no problem loading up in chrome on firefox I get those half-cut codeblocks, not sure how to fix this, any advice would be deeply appreciated!
