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

Hi Folks,

"Block pop-up windows" is enabled in Firefox, but I still get popups from www.smh.com.au Maybe you have time to investigate - a different type of popup needs blocking.

Thanks

I am using firefox 102.0(64 bit) on windows 10. Recently some videos i watch have Error Code: 232011. Also I can't drag and drop shortcuts of certain sites to desktop or folders. It installs an empty file folder.

Firefox was working fine yesterday. But all of a sudden while playing a youtube video it started being choppy. It drops frames, scrolling and video playback are choppy and laggy, there is lag on button inputs, the system is choppy and laggy too while firefox is open, especially when video is playing. I checked the CPU and GPU usage and I can't see any spikes. I have tried refreshing firefox but that did not fix the problem.

OS is manjaro linux (gnome version) latest. Firefox is also at the latest version.

I want to resize a window, without dragging the edges around. I've read the resizing instructions and am unable to find the "resize" icon next to the address bar. any help would be greatly appreciated.

How do I block autoplay vedio?

I know I can block Audio and Video, but I just want to block autoplay video. As if I use the block audio and video it will mute all videos I open, and I need to unmute it every time. I just want autoplay to not start, not mute the video too.

Hello,

When I try to open Outlook by using Firefox it does not. (Installed MS Office 365). When I use Microsoft Edge it does open so I can read the messages. I cleared the cache and it works the first time but when I try to access it again, it does not work. It just not upload the message.

Thank you, Dorina Grossu

I tried importing passwords from Chrome, but the Chrome browser on this machine doesn't actually contain any passwords. Do I need to sync the two on another machine, or is it possible to import from Google Password Manager instead of Chrome?

Hey there,

I use Adobe Acrobat Pro to open PDFs for work. It always worked fine, set up to automatically open PDFs in Adobe, and they save to Downloads folder. For some reason now, after an update, the PDF always pulls up a save box and asks me to name the file (significantly slows down workflow). This only happened after an update.

I've figured out that the issue is related to a way that the PDFs are generated. So if I click it via a link that ends in .html instead of .pdf, it assumes it's a webpage and opens the pdf link in browser, and from there I have to click save, and then I'm prompted to type in the file name.

If I open a PDF link that's an actual .pdf file URL, then it saves to Downloads automatically and names the file "contractfile-1111" or whatever, numbered consecutively. Any ideas on how to get around this?

Thanks

Lately when I attempt to download any pdf file I get the 'file name'.pdf with 'failed' as the result (when I check the Download icon on the FF status bar). I looked in my download directory and I found these 'failed' .pdf files with 0 KB and also some files (same name).pdf.part. I changed the file extension (deleted .part) to .pdf and the files would open in Acrobat. Nobody likes inconsistent problems, but occasionally a pdf will download normally!! But it fails more than it works. Using FF 102.0 (64-bit)

I no longer see a box that contains a variety of search engine choices. I have been using DuckDuckGo and am very dissatisfied with it now. I'd love to know which one(s) people recommend (not google, bing etc, please!) and what the steps are now to changing DDG as my default to this new one? Many thanks (I'm a senior and quite computer literate unless the reply contains tech language I might not understand...)

In the last couple of days I cannot log into Twitter in Firefox. I get a message that something is wrong "but don't fret, it is not your fault". When I hit Refresh, it works, but only once. What is wrong? I have the latest Firefox version. Thanks
