Gesicherte Verbindung fehlgeschlagen Die Website kann nicht angezeigt werden, da die Authentizität der erhaltenen Daten nicht verifiziert werden konnte Fehlercode: PR_END_OF_FILE_ERROR

you are blocking "entry.ostralia.cc" saying the ssl is expired....

BUT SSLCHECKER link text shows it's OK ! and all other browsers allow it...

you could at least allow me to access it under the 'advanced' option like in earlier days...

( the Host provider has mixed up billing for the 3 SSLs on my site , but all 3 are active and valid SSLs...)

I installed portable Version 156.0.1 (64-bit). Since then, the search bar is displayed in the middle of each page instead of the menu bar. Is this a known bug? see image thanks

For the pas 2 mouths i am getting random: "Server Not Found.Firefox can’t connect to the server at" It is happening on random sites that i know for sure they are not down... Waiting , closing fire fox and open it again, refresh but after waiting... helps.

firefox updated and only kept my tabs but didn't keep history or cookies, when i tried to revert the profile to the old data it cleared the old data and made a copy of the new profile with nothing saved, can i somehow get the old data back or is it lost forever

I would like to use the VPN feature with my Firefox account, but it is not available or enabled for me. Could you please check my account and enable it, or let me know what I need to do to get access?

Thank you for your help.

Best regards,

So I just updated to the newest version of Firefox today as of 10-5-26. Except that the purple new tab screen and header for private browsing windows that I really quite liked is not only gone, but the color that's replaced such is nearly black, making it not only much harder to see anything, but overall far worse to look at. Even worse, it doesn't change from such hardly at all regardless of theme, preventing me from correcting it.

I've attached a copy of the previous version of the new tab screen for private browsing that I managed to find for reference purposes, although such doesn't have the header included.

I would also like to take the time say that I've used Firefox for more than a decade, and I think because I haven't had an issue that's been remotely this bad to warrant creating an account to report such says something about how well Firefox has been working for me.

When I watch YouTube videos, Firefox behaves strangely. After a few minutes of watching, I try to scroll to the comments, and then Firefox starts to lag. Scrolling becomes very sluggish, and the entire image freezes while scrolling. The website stops responding, but the sound continues. The only way to fix this is to minimize and then maximize Firefox. Then I can scroll again and the problem starts again. This problem occurs regardless of whether I clear the cache, use an ad blocker, or which screen I'm using Firefox on. Sometimes, one of my screens even freezes and displays stripes. However, this only happens when I'm using Firefox and YouTube. I have no problems with any other applications for exampmple playing games on one screen and let music streaming app playing on the other screen. Even my Cubase 15 work like sweet on booth screens without errors. Why is firefox acting so strange? Firefox never completly stops or closed itself.

Firefox Version 157.0 (64-bit). AMD Software: Adrenalin Edition 26.8.1. Windows 11, version 26H2 installed October 1, 2026 (previous updates also had the same issue with firefox).

I also got some Firefox Updates when i opened it. I was hoping they catched the issue but it seems like the same.

Have a great day :)

I have a bookmark which I use regularly but, with the new version of Firefox, I get the error message NS_ERROR_NET_EMPTY_RESPONSE. I can access the webpage OK on my iPhone. The website is :- http://rasp.stratus.org.uk/app/viewer.php

HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

I have not been able to easily access my bookmarks easily like before. I have multiple bookmarks by category, but there does not seem to be a way to access the different categories currently. I have Windows 11. I have the most current firefox browser I think. I did find from searching support that I could type Ctrl Shift O and scroll down which gives a long list to try to access them, but that is very cumbersome and slow. Do I have to do that every time I want to go to specific bookmarks? The bookmarks that show on the overflow or near the top of the screen are not useful, but the ones I use every day cannot be accessed easily, but are way down a long list. Why is the current version hiding all the bookmark categories?

Every time there is an update, Firefox creates a new profile and hides all passwords etc. It is therefore impossible to work with it now. With 157 I now have a worthless Firefox, because all links, passwords, settings etc have been cleared and a new profile has been created.

When the new update arrived yesterday, I started getting multiple popups from McAfee & Mozilla. Three stay on the screen at once, and when I X one, another appears instantly. This appears to be a scam trojan, but 3 different excellent anti-virus programs have not found anything. This never happened until the latest update. What do you know about this? I don't want to uninstall & start over, but what other suggestion do you have? p.s Usually when I right click on one of them, it takes me to a McAfee ad. I just clicked on one that gave me the option to turn off notifications. That seemed to stop it, at least for now. Am I the only one with this problem? [redacted email from community support forum]

Previous to the recent update I was able to click on a hyperlink, it would load then automatically download the pdf and then automatically open in Adobe. Now it just opens in Firefox. I have changed the settings to open downloaded pdfs to Adobe but it still opens in Firefox and does not download. I have tried changing the PDF setting to save automatically and it still does not download or save it just opens in a new tab in Firefox.
