PR_CONNECT_RESET_ERROR since newest version of Firefox 91.0

Since I updated to Firefox v.91.0 I get this error: Secure Connection Failed An error occurred during a connection to support.mozilla.org. PR_CONNECT_RESET_ERROR … (read more)

Since I updated to Firefox v.91.0 I get this error:

Secure Connection Failed

  • The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

when ever I try to connect to websites via Firefox only. I've tried many things like reinstalling Firefox and I know its an issue between Firefox and my Antivirus (Kaspersky,) but this didn't happen before Firefox updated to v.19.0 though. I've tried https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and many other things but nothing works to fix it. I've switched certificate stores and other 'fixes' I've read on this website and others to no avail. It does this with or without any extensions in Firefox.

This only started when I updated Firefox to version 91.0. It doesn't give an errors/issues on any other browser I've tried so far (MS Edge and Chrome) so must be something with the version 91.0 update?

Any ideas to fix this would be great. Thanks!

Thunderbird 78.6 (32x) Windows 10 Pro 20H2 Today I stumbled with a problem, this was not the case before. File extensions for Documents attached to an incoming letter are truncated. So for the Excel file, the extension is .xls_ instead of .xlsx As a result, the document does not tear off. You need to save the file, change the extension in the explorer, only then you can open it. Can someone help solve this problem?

When I hit paywalls, I "trust" site with ghostery. Still hit paywall. Can't find anything in Kaspersky that will let me turn off anything. Meanwhile there is no red stop sign ad block in the upper right corner of FF. This is 2 hours of my life i will never get back and I still cannot get past paywall. Is the little red stop sign (which I cannot find in firefox - using most recent version) hidden somewhere other than in the drop down menu on the upper left hand side?? It's not in the drop down menu.

I am ready to kill everything and start fresh with Tor. That's drastic but I have been directed in circles for too much time. Life is short and I am no longer entertained with this mess.

If I go onto the Aljazerra site, to a page where there is a video, all I see is a white space. For example https://www.aljazeera.com/programmes/witness/ has a Survivivors Ebola epidemic video at the top of the page but in Firefox it shows nothing but a blank space. I have supplied a screenshot. Although the screenshots show videos further in the page they are in fact links ,which when clicked also result in only white space. However if I use the Flashpeak Slimjet browser it displays all the videos with no problem. Can anyone help, as I'd rather stick with Firefox

Hello! I'm using Windows 10 (1809) with Mozilla Firefox 66.0.1 on my PC. Since many Firefox versions I have the issue, that Firefox crashed immediately at the first start. The second start and all other subsequent starts works fine, as long I will not log off and log on again. Then Firefox crashes again on the first start (same behavior as mentioned). Here a list what I have done/checked so far: - Firefox Crash Report is not available, no crash information windows appears - Firefox is installed in the current latest version - All Windows 10 Updates are installed - Newest Nvidia Graphics driver is installed - New Firefox-Profile created (same behaviour as with my current profile mentioned above) - New Windows User created (same behaviour as with my current user mentioned above) - Firefox reinstalled, with deletion of the installation directories and profiles - Firefox hardware acceleration disabled - I switched off my Kaspersky Internet Security before the first start

Nothing helped. When I click on the Firefox Icon, a Window opens for a few milliseconds and closes immediately. (No more Firefox processes running in Task Manager). Then I click again on the Firefox icon, and the browser opens perfect and runs stable. After the session I log off/shutdown the PC. When I start the PC again the next day and log in, I have the same issue again.

Does someone has an idea how to solve this issue?

Any recommendations are very welcome! Thanks in advance, Simon

I have Kaspersky Total Security which is great for on line banking because it uses Safe Money, but since the latest updates from Firefox I am unable to use it. I keep getting an error message in some sites and others won't even open at all it goes straight to the normal window without protection. As kaspersky is a add on, do I have to grant permission in private browsing to allow this site to be accessed. kaspersky do not know what is causing the problem and believe it is Firefox that is causing the issue. To be honest Kaspersky has talked me through several procedures and still it will not work.

So, do I need to grant permission in private browsing and if so how do I do this please as I have looked at several forums and I would be grateful for some clarification?

Many thanks

Julie

Kaspersky Internet Security 2108 using Safe Money. Mozilla Firefox Browser version 64.0 (64-bit) in Private Window. Windows 7, Password Manager is not used.

I inadvertently saved a password in Safe Money, I don't know how this happened.

When I opened a URL in Safe Money, a small Firefox window popped up. It would say "Would you like Firefox to save this password for URL?" Save? or Don't Save? are to be selected. If I did not select either, the small Firefox window kept popping up every time I opened the URL. Because of my error, I do not have the pop-up anymore but I have a saved password appearing as masked characters. If I delete the saved password from the box and refresh, I can force the small Firefox window to pop up. The small Firefox window will show a blank user-ID and a password in masked characters.

I tried to remove the URL from Safe Money, then disable Safe Money, then enable Safe Money and add the URL back. Saved password is still there. I think I know how to change the settings in Firefox and delete passwords, cookies, etc. but none are being saved. I don't see any other options I can play with.

I uninstalled Firefox and deleted the folder for it in the C: drive to remove any trace of old browser settings. I installed Firefox version 64.0 but was not able to launch a protected browser. Safe Money has options to play with but none of them worked. I undid version 64.0 and installed version 49.0 that I had the EXE file for. I was now able to launch a protected browser in Safe Money. I upgraded Firefox though the Help menu and so it upgraded to version 56.0. I then upgraded to version 64.0 and I was again able to launch a protected browser in Safe Money. I added the URL to Safe Money, opened the website and the saved password is STILL there.

Using FF 64 on a Win10/64bit.

All other browsers work fine (IE/Chrome/edge) i think (!) after windows10 update (the 'october update') i just installed since PC just came out of box... it stopped working. PC has been on and used with FF for few days already, had no problems, synced bookmarks fine etc.

Now: - no url loaded if entered manually - no url loaded if selected from bookmarks - no settings page loaded most of times. - sometimes (!) i can load "options/preferences" - i can never load about: functions

Checked and done so far without luck: - re-install (removed, restarted, checked for removal of Mozilla directory, installed) - created new profile - checked proxy settings in settings : manual / no proxy - checked windows firewall settings and even defaulted them etc - started in 'safe modus' (no extensions loaded) - not using 'offline' modus

anybody? i've spent a few hours now and near close to leaving it and using Chrome...

Problem appeared 5-6 days ago.Runing windows 8.01,Kaspersky internet security(for several years had no problem with it). In Google Chrome and on i Phone,that issue does not exist (yet). Other web pages still have no souch problem(to be precise I'm not having that kind of problem :ONLY WITH gmail.com  ! )

What might be the cause , and how to solve it. Did Google change something,so that earlier versions of firefox do not work with gmail anymore (keeping the 56.0.2 because of Ant video downloader)

THANK YOU FOR THE ANSWER AND HELP IN ADVANCE !!!

Only in FIREFOX, my TITTER safety settings are changed & locked automatically. If I try to change the settings as I desire, I may not be able to do it as it can NOT be changed. I am using FIREFOX for years. I am only encountering this problem recently after I installed a fresh version of FIREFOX.

I have just been forced to use Google Chrome instead of FIREFOX just for this problem. I can NOT change * uncheck either: -Hide sensitive content -Remove blocked and muted accounts Please see the photo & inform me if I could correct this problem so I can use FIREFOX back again. In previous version or via CHROME, I can change these 2 setting as I want, but not the most current version of FIREFOX
