Yesterday, Thunderbird was automatically updated to 91.4.1 on my Windows 10 laptop. Now my gmail accounts fail to authorize. When I start Thunderbird, a splash screen appears "Secure connection failed". The title bar on the splash screen says "Enter credentials for xxxxx@gmail.com on imap.gmail.com" (xxxxx represents my username). There is nowhere to enter credentials as far as I can see. I know for sure that the password I used was correct as I just signed in to gmail using a browser. Please help!

Before this latest update i could go to the list of messages in my inbox, rigth click on a message and selecte print preview, i was using this feature to avoid opening emails that i was not sure if it was spam or something that i would be interested on. The option is no longer available with Thunderbird 91.1.1 (64-bit), what happen, why this feature was removed? Programming team running amok again? or QA team sleeping at the wheel? Please put back that option thanks

on GitHub the commands are all based on Java https://github.com/mozilla/policy-templates#preferences

Is there a list of all available registry settings? Or where do these Java options come from, where can I read them out?

Yesterday morning, I started receiving a "secure connection failed" message when trying to retrieve email from imap.gmail.com. I searched Mozilla Support and tried the following, which apparently worked for others:

"First, delete all entries in Tools/Options/Security/Passwords/Saved Passwords. Press Alt if the Menu Bar with Tools is hidden, or click the 3-bar icon, Options/Options/Security/Passwords/Saved Passwords.

Next, use these settings for IMAP accounts: imap.gmail.com on port 993, SSL/TLS, OAuth2 authentication, User Name = email address. For POP accounts: pop.gmail.com on port 995, SSL/TLS, OAuth2 authentication, User Name = email address. For SMTP: smtp.gmail.com on port 465, SSL/TLS, OAuth2 authentication, User Name = email address.

After you've deleted the passwords, restart TB and enter the regular account password, not an app password, in the OAuth browser window when prompted."

It doesn't work for me...I keep getting error messages. Suggestions? Thanks!!

I am a senior user and need assistance. I am unable to clear history. I followed directions sent by Fred McD, and inadvertently removed my profile. I have saved the profile, but cannot open Firefox replace the profile information. Can someone help?

Also, if someone should ask a question, how do I reply?

Thank you, Blair Ryan [removed email from public]

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?

I tried to log in to thunderbird, but my password is no longer accepted. My name ([edited] @gmail.com) seems OK.

I need two-step authentication, but thunderbird does not offer this.

I reinstalled thunderbird, and it remains unusable.

I'm getting old, so I guess I'll have to start writing down passwords.

Can anyone from firefox send me the instructions to get rid of this message. Secure connection failed and Firefox did not connect

Please avoid sending links with tons of info to read because I don't have time to follow.

Many thanks Jorge

Today Firefox stopped altogether and dimmed the entire window and popped up a "Try the Firefox VPN" message. I use Firefox specifically to get away from disruptive, intrusive violations like that. This needs to be removed immediately and never ever happen again. It's completely antithetical to the core values of Firefox.

Furthermore, several users have reported it breaking their browsing. See this Reddit thread:

https://www.reddit.com/r/firefox/comments/13rnt88/why_is_firefox_windows_11_version_showing_me/

This affected me on Windows 10 running Firefox 113.0.2 64 bit.

I browsed a clothing website for less than 5 minutes by typing in the address and not using any links. Shortly after I receive an email asking if I was still interested in what I was looking at. Does Firefox share my email address with websites I'm visiting? I believe the email is coming from SafeOpt, not the website I visited. I do have "do not track" options selected in Firefox.

At the top of the about:preferences page, in a gray box, it says, "Your browser is being managed by your organization". Why? This is my home computer! How can I manage my own browser?

Version: 91.0.1 Settings--> Privacy and Security -->View Certificates-->Your certificates--> pick target cert to delete-->click ok on confirmation window --> click ok on Certificate manager window.

Restart FF, Settings--> Privacy and Security -->View Certificates-->Your certificates, the deleted cert is on the list again.

The same happens on that under Authorities.

Using Windows 10 OS Firefox 95.0.2 (64bit) - default browser. Since update to 95.0.2, everytime I want to use the Firefox or Thunderbird Support forum, I'm asked to login before I can respond to any questions. I am a regular helper on the Thunderbird Support Forum. So this is driving me potty :) This can occur if I exit Firefox or awake from sleep mode or at random times whilst I'm using Firefox with Thunderbird Support in a Tab and I may be using Bugzilla.

Note: I'm not using two step.

Menu app icon > select email address > Firefox Account When I select it auto uses the 'Synchronise now' It continually shows 'Logout' - I never need to Login.

I noticed my settings had been altered when Firefox updated. I have reset the about:preferences#privacy Selecting 'Use Custom Settings' 'private browsing mode' is NOT selected. 'remember browsing and download history' is selected. 'remember search and form history' is selected 'clear history when firefox closes' is NOT selected.

My history is looking ok.

I would appreciate some pointers to discover why I'm being logged out of this Support Forum. I want to stay logged on to account.

I want to use discord in firefox instead of using the pc-program. It appears that my firefox.cfg has some preferences that block discord from gaining microphone access. I never used multiple firefox profiles but that changed now, i created a firefox profile for discord purpose only. However my firefox.cfg is active in both the default and the discord profile, again blocking microphone access.

As i said currently i use firefox.cfg and autoconfig.js to customize firefox preferences, but since this makes it impossible for me to use discord i will have to find another way to modify firefox, so the question is how can i use multiple firefox profiles with different preferences? Can this be done with a user.js file? After all what is the difference between using firefox.cfg and user.js?

I forgot my primary password in TB 102... None of the directions have helped me to remove the present primary password. warning, I am 70 and need hand holding directions. The directions I have found so far have to do with an earlier version. Specifically, this does not exist in my version of Thunderbird: "Starting from the app menu button ≡ or the main menu, choose Tools -> Developer Tools -> Error Console."

Hi, i have a problem. My gmail account passwords are gone I've checked in Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords" but there is nothing. Neither to the "account.google" nor "google.com". I have always had the pre-filled username/passwords fields for years. Only the gmail password are missing. Someone can help me, please?

Last night my Firefox 94.0.2 was hacked. When running Firefox, it would lock up my desktop. It disabled Norton Security, it disable other installed security software, and it disabled Windows System Restore. The hacker put up a message claiming to be Microsoft Support, with a phone number to call for help. This was a scam. I ran Firefox refresh, and that removed the hacker's program from Firefox, but then I had to do a full repair of my Window's installation. To protect my system, and prevent this from happening again, I added "xpinstall.enabled = false" into about.config. Please let me know if this will prevent a web site from installing a dangerous hack into Firefox, or if there is something else that I need to do. I have used Firefox for years, and have never encountered this problem before. Firefox is my favorite browser, but I am now afraid to use it. Please advise me what to do. Thanks, Jim

After today's update of TB to the latest version (91.8.0), the system still requires a login to a Google account. When I enter the data, nothing happens. I can't download or send any mails.

So far everything worked without problems, the authentication method is specified OAuth2, mail client as POP (not IMAP).

Don't you have any recommendations? thanks, Jan
