Is there a way to COMPLETELY REMOVE the Calendar junk from Thunderbird?

I'm a 15+ year TB user, but I promise I will drop it if you don't fix or remove that junk you call Calendar. Let us disable it totally and go back to old TB integration with other calendar applications. I've used it in Win and MacOSX with any issue for 10+ years.

In the last 6 months I'm spending my precious time to fix errors, sync and auth issues about Calendar. I do not need a calendar in TB, I do not want it as I already got all the solutions I need for scheduling calls and business activities.

I activated it only cause TB dropped support of calendar invites by email.

I'm tired of this fascist and blind approach to the community. If this tool will stay there and still cause trouble I will move from TB to another email client for the first time in 17 years.

So please, is there a way to completely remove it and connect TB to any other calendar applications directly?

My drafts folder on Thunderbird has gone blank. I cannot access them and the contents are not visible. When creating an email, its saying it cannot save the draft either, yet the number of drafts keeps increasing. Any assistance with this is most welcome!

Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly.

Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked.

I am attaching pictures of how the error shows.

Please Help.

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

Error: "Secure Connection Failed

An error occurred during a connection to accounts.firefox.com. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

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

When it happens: - Irregular frequence. The same websites once work once don't. They work with Chrom/Edge/From my mobile(same wifi/router). - Sometimes I have to refresh the page a few times - Happens for all sort of webistes. From local news, to GitHub/Youtube/Google/Any website

Steps I have taken: - Cleared cache/cookies - Reset PC/Firefox - Cleared all extensions - Deleted Firefox (And manually deleted all folders in AppData related to Firefox) and reinstalled afterwards

Nothing helped. Any idea what is going on? I checked Mozilla documentation for SSL issues, but it didn't help either

A month ago I started to have problem with twitch. After 5minutes or 2 hours- random times or random tabs, if I have opened more than 1, which is always the case. Some tabs or all, again it's random will give twitch 2000 error and refresh, closing tab,etc nothing will work, except closing WHOLE browser, not just tabs and this is not guaranteed that it will work.

I'm losing my mind with closing whole browser-windows-tabs on different monitors and then re-opening all of that again when I get 2000 error and I always do get it.

Did like 50 re-installs, it's always the same. I tried to go back to older version, but Firefox always want to create new profile saying I have old version installed and I DO NOT want that, I want everything as it is right customized,etc right now.

Hi, Having just upgraded to Thunderbird 114.0b6 (64-bit), I seem to have lost the vast majority of my email messages and no longer have a unified folder.

I had/have several email accounts. Most were POP, so before upgrading, I changed them all to IMAP.

I then installed the new version. This did not pick up my existing Thunderbird profile (which is on my D drive), so I imported my old profile from the D drive. This did not import the server settings, so I reconfigured them for each account.

For some reason, only a small minority of my old email messages seem to have been imported, the oldest going back as far as 2015. The vast majority are missing.

I received an email message a couple of days ago (via my new Thunderbirds installation), but it is no longer visible in the Inbox of the account that received it. If I search for the message, it shows up, but I cannot find or access the email itself.

Additional to these problems, I cannot view all my emails in a unified folder. I select the Unified Folders option from meatball menu, top left - Folder Modes, but nothing changes and when I re-enter the menu it is unchecked. Likewise, if I go - main menu/View/Folders/ and check Unified, it does nothing and does not remain checked.

I've read all the available documentation and watched the YouTube Folder Panes video, but found no solution.

I would be very grateful for any assistance you can offer.

Regards, David

Hi there,

we have a problem with our work email. It is operated on Microsoft Office platform. However half of the people in our company uses Thunderbird over MS Outlook. Few days ago our mail clients stopped to work on Thunderbird. I enslose the screenshot. On Outlook its still fine and working. Licence with Microsoft is therefore valid. Ohter mails(my private mail, or my second wokr email) work with the Thundrbird still fine.

Can you please help us, working in Outlook is terrible and making my life hell. We would like to stay on Thunderbird. Thanks a lot and have a nice day, Petr.

This morning, my wife's Thunderbird messages on version 102.11.2 were blank. They were IMAP messages on gmail, and a quick check showed the were not blank on the server. I tried deleting the entire gmail folder set from the IMAP mail directory, but that only made it worse. So I loaded my wife's profile from a backup. It solved the problem, but for how long? Another person with a similar issue previously noted that another symptom was a vast increase in storage requirements for the profile, and I saw that the profile was more than three times the size it used to be. There were a series of files named NSTMP in the gmail profile that aren't present on my profile. I deleted them from my wife's profile and recovered the storage, without changing the performance. I suspect the profile became corrupt and the corruption resulted in generation of multiple NSTMP files, and eventually started wiping out message content as well. Because I think the profile I restored was likely corrupt, I am guessing this problem will recur, unless someone can tell me how to fix it for good.

I'm running Windows 7 with all updates current as of the time MS stopped supporting it.

my wife is using T-bird for email and now is getting the 'UID fetch error message, no previous issues till today. She doesnt get a lot of emails so dont think thats issue, she goes through optimum server.

Just recently been experiencing the 400 Bad Request error on Kick.com (a live streaming platform) for about a couple hours now. Never had any issues prior.

Was informed that this same issue is happening on other browsers and the only solution is a "quick fix" (clear site cookies) which only works for literally a second. When the page is reloaded the error message pops back up.

Please help, thank you!

The last update 113.0.1 was when I really noticed it being slow. None of the current suggestions have any effect. I have restarted several times, cleared cookies and history, flushed dns and have gone through all settings. Privacy is set at "standard" and not using a VPN and have turned off add blockers with no effect either. I have to check, but I don't think I have any add-ons except for color on home page.

If I do a speed test, ping is kinda slow, download is half what it should be at times, and every test shows ZERO upload all using several sites to test from . The only thing not done is shutting down av which I won't do. Anyone else seeing this issue? Any other suggestions than the go-to stuff here? Windows 10

The entire INBOX disappeared. How can I get Thunderbird to show it again?

I have a Windows 10 PC. I just downloaded thousands of emails from my CenturyLink email server. The emails were apparently successfully downloaded, but I can't see any of them because the entire INBOX disappeared. When I open Thunderbird, all the other folders are there, but no INBOX.

How can I get the INBOX to show again?

Could this in any way be related to IMAP vs. POP. I used IMAP. I saw several people reporting problems with IMAP. Should I switch to POP?

I saw an other article about the same possible but they had a problem with an extension but I dont have that extension but still have the same problem. Whenever i watch twitch or youtube and i alt tab or switch tabs my audio and video stops playing.

I have five separate email accounts on xfinity: call them b, 3, 7, a, and p. All of them are set up in Thunderbird. Any attempt to send an email through Thunderbird on any of the accounts opens a window requesting the password for 7. The password for 7 is in Password Manager. If I copy and paste the password from the Password Manager or from KeyPassX I get the "Login to server smtp.comcast.net with username 7 failed" with an "Enter New Password" button in the pop-up. The password is correct and still current as verified by opening my xfinity account directly. This has been happening sporadically and randomly (correcting itself sporadically and randomly) for many months and for several updates. I have tried all the suggestions posted on this forum for other victims, but none of them have been successful for me.
