Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to scgi.ebay.co.uk because this website requires a secure connection.

What can you do about it?

scgi.ebay.co.uk 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. You can notify the website’s administrator about the problem.

I don't have any account icon in my tool bar and no option to sync. I try to login/sign up to sync through this page https://www.mozilla.org/en-US/firefox/sync/ and the loading icon just spins and spins and spins and spins and spins for.ev.er. Please help. I just want my browser to sync on different devices.

Hello, I'm running Firefox 78 on fresh Debian Stable installation and I cannot access certain websites. I followed step-by-step the instructions by Mozilla Support found here, with no result. Of course, I tried completely uninstalling and reinstalling Firefox, renaming .mozilla folder to create a new settings folder, deleting .cache/mozilla etc. I use no proxy, and I can visit all those certain websites form other browsers of this installation. And I'm looking for a solution for more than 2 weeks now. Any help is welcome!

In new version of Firefox (89) Default theme is installed but refuses to load properly it looks like the Light theme, when i am switching it to Light theme and after Default theme there is no difference it looks like Light theme anyway...Can you help me with it?

Greetings,

I just updated to Firefox 78.15.Oesr and now am unable to reorder my open windows. As a student, I may have several projects open at a given time, and like to have the project I am currently working on, next to the open Firefox window, for quick navigation between the browser and project. This option seems to have been disabled with the update. It is enough of a deal breaker that I may pursue reverting to the previous version of Firefox.

Also, the inability to delete bookmarks, and to close the bookmark window after selecting "show all bookmarks," remains a persistent frustration that I am surprised has not been addressed. With so many browser options available, these subtle annoyances are enough to prompt me to again shop around for alternatives, after being a Firefox devotee for over 10 years.

Thank you for your help, Josh Baker

Firefox has been my favourite browser for years but I am about to uninstall and kick it to the curb!!!

Every time I want to attach/insert an image (on many different sites/platforms/apps) it freezes ~ I have to shut down and start again, losing whatever I have been working on. I have uninstalled and reinstalled a few times and have checked ~ all is up to date.

Any advice would be greatly appreciated!

Thanks a mil!

hello.

I currently have a problem not being able to stream films on netflix, amazon prime, disney plus using firefox browser. This issue happened overnight. Depending on the site a certain error code message will pop up then the same yellow bar at the top says "the widevineCdm plugin has crashed..." i have reloaded the page, sent the report. uninstalled and installed firefox...but the issue continues. This happened roughtly 2 weeks ago and the problem hasnt resolved itself. Safari allows me to stream most sites barr disney plus. Can anyone help. I've tried many of the things google has suggested and it hasnt fixed the problem. I have tried chrome also, there seems to be the same issue. does anyone have suggestions

Hello,

I just read an article from CIRA (Canadian Internet Registration Authority), dated July 8, 2021: https://www.cira.ca/blog/canadian-shield/mozilla-firefox-cira-canadian-shield?utm_source=newsletter&utm_medium=organic-email&utm_campaign=FY21&utm_content=the-dot-11

In it, they write, "Mozilla is enabling CIRA Canadian Shield as the default trusted recursive resolver (TRR) for Canadian Firefox users." I'm such a user. I also know *just* enough about the vast electronic highway system called the "Internet" to know I need safety and security measures in place.

I'm using FF 78.12 on MacOS Sierra.

I thought I'd see if CIRA Canadian Shield was the default proxy by going to Preferences > General > Network Settings. "Enable DNS over HTTPS" is selected, and the default provider is "Cloudflare." I clicked the drop down menu to see if CIRA Canadian Shield was offered as a selection. Alas, it is not. So, I selected "Custom" and typed in "CIRA Canadian Shield" (without quotation marks) and pressed "OK."

My questions are:

1) Is Mozilla enabling CIRA Canadian Shield by default as suggested in the article? 2) If so, why is it not indicated in the drop down menu? 3) Have I enabled CIRA Canadian Shield by typing it in the name as a custom proxy server?

Thank you for your help in advance. Please note, I have a rudimentary understanding of how this all works, so your simplified and somewhat non-technical answers are appreciated.

By fixing the very first option you come across as soon as you go into General Under "Startup" The setting called "Restore previous Session"

Usually, a checkbox, is a boolean ON OFF.

Once more, this leaks data. For instance, logging into my webmail rebooting the machine, next time i launch firefox it spawns the same session again. This contradicts with the very first option under "General" -> Startup

If this was a public machine, some one would now have access to my email.

It seems that this is OS specific. But really, i don't care. My complaint stays the same. The option is broken, and firefox leaks data therefor. I no longer trust Firefox. This sort of stuff is not done deliberately.

Once more. perhaps bit logic is too complicated for you UI designers and a quantum gyro is more to your liking? Cause this is NOT normal.

Hello community, would anyone kindly help me with this issue I'm facing? How do I export Logins and Passwords on Firefox running 78.10.1esr (64-bit) on a Mac. The export funtion is not available here and I know the this option is only available on 79 and after, but I'm using a mid 2012 Mac Pro running 78.10.1esr. Is there any way I could still export the logins?

Thank you kindly.

Hello,

It is suspected that latest version of Firefox version 78.11.0esr (64-bit) is causing operathing systems to crash. I have not seen it on Windows platform as I am not using it. Platforms I am using are OSX and XUbuntu. The error occurs lingering on a site for a very long time. First it starts getting screen graphic errors like, some pixels are not being updated correctly. Then after a while screen starts to flicker, in a massive state, like the graphic processor is broken. In some cases with command key strokes one is able to kill Firefox, screen is back to normal and one can continue working. Facebook is the site that most commonly is causing error, but there are also other sites.

My wife works on her Firefox browser. She can't print (nor preview) to PDF. Yet she can do this on a Safari or Chrome browser. I share the same computer, but using a different account. I have no problem printing/previewing to PDF on my Firefox browser, when using my account. This problem is not recent.

We use a Mac mini (2018), macOs BigSur 11.5.2, Firefox 78.13.0esr (64-bit)

Thank you for helping with this problem.

DISCLAIMER: THIS HAS BEEN SOLVED! Dear Firefox Team, I have installed Firefox-ESR on my HP Chromebook 11, using linux. I saw it going slow so I searched up stuff. I went to "whatsmybrowser.org", saying Firefox 78. I saw that on an article there is 91 and 95. It is 11/3/21, and no update is showing up which a help article said "On 11/2/21, users can update to Firefox-ESR version 91." I couldn't update, so I am now asking for help. Its also going VERY SLOW which I can barely run scratch, google, and even the homepage. Please give me answers so I can fix the problem. Thanks, cogithedog.

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.
