Firefox Support Forum

Hello Firefox Support, I need help to upgrade the version of the security protocol that enables access to my NAS unit. Now the message;

"Secure Connection Failed An error occurred during a connection to 192.168.1.201. Peer using unsupported version of security protocol. Error code: SSL_ERROR_UNSUPPORTED_VERSION

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox."

indicates I no longer can access my page until I find the remedy to this issue. Thank you in advance for cooperation and help with is matter.

Hey, I just reset my computer, reinstall firefox and it sync correcty. But I had to delete the windows session to create another one to be in my domain. Now when I try to resync it just load and then stop over and over again. I didnt do anything to delete the sync option on firefox.

For awhile now whenever I visit Kickstarter, I never get the full page to load. I mainly notice it in the header where the info for the campaign information doesn't show on Firefox. I've tried playing around with my widgets and protection to see if that would allow the page to fully load, but nothing has worked.

On certain (very few) web sites, I get a symbols font showing instead of text. For example on www.xe.com I have tried a refresh already, disabled addons etc..

Weirdly, THIS support form suffers from it so I am attaching pictures to illustrate the issue.

I have googled the usual stuff to no avail, so really stuck now...

many thanks for any pointers, Lozzy

Hi, After the last update Firefox asks me what I want to do with the pdf files and to choose between Open in browser, Open with and Save file but even if I choose Open in Firefox it always downloads the file in the download folder of the PC and then opens it, This is really annoying because then I have to delete them manually. What can I do? Thank you

My Last Pass add-on was disabled after the last update of Firefox and when I removed it and tried to reinstall, the message was that the file was corrupted. What do I do?

I just upgraded to Monterey on my Mac running FF 101.0.1 (64-bit). I cannot add new search engines to my list of search engines. I'm trying to add DuckDuckGo without success. I have Google, Bing and Startpage. I click on Find More Search Engines, select and add DuckDuckGo but while it appears as an extension it does not appear in the list of search engines.

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!

The red Tilde on my spell check in Facebook does not go away when the new correct word is chosen using Firefox., also the correct word is not displayed in the sentence until your push enter, it will then be corrected however before you push enter to post it, it will show it as the misspelled word. This issue is not prevalent on other browsers such as Chrome, Edge, Brave.

I am suddenly getting a number of web sites, which I have visited in the past and I know to be valid and secure, giving the Secure Connection Failed errors. Have you changed the programming behind Firefox which iis causing these problems. How am I supposed to get to the web sites with no ability to over ride the failure?

The rendering issue is not seen with Chromium (Linux) or Safari (Mac). I have no alternative for Solaris :-(

I have read the tips etc, reset everything, but there is no difference.

This has been happening for a a couple of years, getting progressively worse, It has got so bad, I have stopped using FF on all but Solaris now. (and I have been using it for a long long time).

I need someone to direct me to what information/data is needed to be collected so someone can comment. Do you have any favourite page load test web sites that I can send out put to you from?

This website loads, but I'm unable to sign in to my account, nor can I see the details of the pages. It works fine when I open it in one of M'Soft's browsers, but I prefer Firefox!

Sometimes, if the computer is offline and Firefox is open, when the computer goes back online Firefox can't connect to any website, with the page "Hmm. We’re having trouble finding that site.". The only fix is to close Firefox and open it again. Going offline doesn't always do this, and while I'm not sure of what exactly causes this to happen, a way to easily reproduce it is:

• Turn off the Wi-Fi;
• Reboot the computer;
• Open Firefox;
• Turn on the Wi-Fi;

After the computer is connected, refreshing the page sends you to "Hmm. We’re having trouble finding that site.". You have to restart Firefox.

A way that doesn't 100% reproduce it, but works enough times, is to reboot the computer without turning off the Wi-Fi, and open Firefox as soon as possible (before the computer manages to connect to the router, which is the part that isn't always consistent). Rarely, it happens after suspending the computer, or after a disconnection due to an unstable connection. I can reproduce it in Firefox's safe mode. I have a hunch that maybe this is related to networking drivers.

I'm using a Lenovo IdeaPad 5 14ARE05 (Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)), Linux NixOS 22.11 (I don't know about Windows).

Ask me for any log you might need.

This is kinda a duplicate of https://support.mozilla.org/en-US/questions/1078253, except that their solution does nothing to me.

Hi! I have the Firefox browser on my MacBook Pro and I also use the Mozilla VPN. I’ve been trying to sign into my Firefox account for several weeks now and keep getting a ‘Cookies and local storage are required’ error message. The problem is that cookies are already enabled. I have tried restarting, updating the browser, doing it with the VPN on and off, listing firefox as an exception, and everything else I can think of. I’m currently entering this on my phone, because the browser also won’t let me sign into my account on my laptop without enabling cookies and local storage.

Any suggestions? I keep getting stuck in a loop.

I would like Firefox to remember exceptions and store specific cookies that I need for the Microsoft authenticator, and other two-stage logins. Whatever setting I choose (untick delete cookiex and sitedata, assign websites to manage exceptions etc) upon closing Firefox everything is deleted, always. This means I can't use any authenticator to remember me when I want it to do so.

I used a third party cookie extension (Cookie AutoDelete) to whitelist some sites and it worked perfectly fine until an apparent recent update by Firefox. I am on Firefox 101.0.1 on Mac.

Any ideas?

I wanted to know to how to fix this issue.

Please help me with this

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?
