Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

The horizontal scroll bars had been missing for certain URL in firefox since mid last year 2023. I just downloaded the latest version for windows 11 and it is still missing.

I have checked the settings > General > browsing > related to scrollbars and they are all checked, namely: - use autoscrolling - use smooth scrolling

But it is still missing! I generally use firefox for my work and Google chrome for my personal use - to compartmentalize my browsing content/history. Now I will have to ditch firefox and use chrome only for both work and personal if this is not fixed.

Code sent to my email about firefox pw change didn't work? tried 5 times!!! legally blind pls help me thx!!!

Thanks Deborah/Debbie Davis

1. I use a startpage called IGHome. That address is set as my default to open to. When it opens I notice that the address is not secure. When I add https:// in front of it, it does in-fact open, which is good. Even though I added that prefix to the address on the Internet Options page in my system, it still continues to open the old 'unsecured' way. I also cleaned IGHome out of my system before resaving it. Is there anyway to get my system to recognize the secure version? And, if I open any sites with passwords on the unsecured version, they DO open as secured so in reality I am still safe (even though my system is not opening the https site).

2. Also, on my IGHome page, there are 'Show Your History' and 'Show your Bookmarks' tabs at the top right in the toolbar. When I used to open them they would open almost flush right. Now they open almost in the center. Is there a way to make them open in their previous flush right location again?

Thank you in-advance for any time and assistance!

I want to sequester Address Bar Function in the main address area for web address or native locations, from search function contained inside of the window, the search should be only a web search, but I think that part is covered in standard settings, so address. Thanks Much

Similar to this https://support.mozilla.org/en-US/questions/1440015. However, I installed Firefox this way https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions

Issue happens in both MX Linux and Linux Mint (Firefox 129.0, 64 bit)

trying to log in to Barclays Bank and keep getting a pop up message loginappcontainer.do 0 bytes I have never seen it before and it is suspicious, please help. can not screen shot it either.?

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

Hello one and all,

For the longest while, FF has been wasting a lot of my time by being non-responsive a lot. Is there anything I can do to eliminate the non-responsiveness?

The other problem that I have experience also on a regular basis when searching is waiting for Google to transfer info to FF.

Years ago, this wasn't the case. I am also hoping that a fix exists to speed up FF.

Thanks for any help I can get to put these two issues behind me.

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

I get this sometimes when moving/backing up profile contents, even when the the eventual path of the moved contents will be shorter than the original.

I have a problematic profile, so I copied it's contents to another folder with a shorter title in the same directory, but I prevented from including the file in question.

In this particular situation, the file in question is an .html file opened in a session tab. I assume It's omission not going to be detrimental.

Has anyone seen this sort of thing occurring with files that directly affect profile operations? I'm wondering if that sort of thing might be contributing to my current recurring profile issues.
