Firefox Support Forum

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.

Sample page https://www.smh.com.au/politics/federal/inflation-tipped-to-fall-while-rent-costs-to-buck-trend-with-15-year-high-20230721-p5dqbj.html

Thanks

When I click a link on a website, a new Firefox tab opens with this message: 400 Bad Request Request Header Or Cookie Too Large nginx/1.18.0 (Ubuntu). This is new behavior; it was working fine until yesterday. Can you tell me how to fix it?

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 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.

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?

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.

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.

Starting about 2 weeks ago everytime I access Facebook, it starts reloading pages and I can't stop it. This is the only site I've had the problem with and it always starts happening when I have paged down several pages. I've tried changing settings, and even uninstalled the system and re-installed to no avail. Something has changed so please fix it!

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,

I get Secure Connection Failed - SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT error code randomly while trying to open youtube.com. It works with other browser. Please help to solve this problem.

Hi,

I recently created a new profile in Firefox as I regularly do, as a consequence I found that the "Page Setup" menu option has been removed in a past release.

I can't fathom why this has been removed, I "print" plenty of PDF's and like to customise the Headers/Footers based on what I'm "printing".

Searching for a fix suggests either installing a 3rd Party Add-on or "hacking" the "about:config". This is not user friendly in the slightest for something that has been around for literal decades.

Forcing a user to install an Add-on or even go through "about:config" and set "print.show_page_setup_menu" to true is bonkers!

Yes, bonkers!

Please restore the "Page Setup" option as default, please don't remove it or stealth hide it.

Sincerely,

Jay

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

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

Is it possible to restore previously deleted pages in FF history? There are instructions for FF in Windows but I am using Ubuntu 16.04 esm and the FF version is 102.10.0esr.

The pages were deleted  several days ago and the computer has been shut down and rebooted many times since then.

If it is possible doesn't that defeat the object of deleting history pages?

Hope someone has an idea! Derek
