Our company email host uses Office 365 exchange. As of yesterday (26 May 2022) all emails were blocked to Thunderbird on our networked office PCs using Windows 10. We cannot send or receive email on Thunderbird (fortunately it still comes through to our iPhones). Our host hold us that Microsoft has "recently started blocking POP3 connections on software such as Thunderbird".

 How do we fix this problem so that we can continue using Thunderbird, which has our email records for some 10 years?  We do not want to use a Microsoft mail client unless we really have to!  I imagine we aren't the only ones with this problem, but I couldn't easily find it by searching help.
 Many thanks!

Why? This is terrible. Why does it delete all emails without asking?

A lot of times while coding I press Ctrl+S to save Visual Studio Code and update live server (while watching on firefox the result). The problem is that when I'm focused on Firefox Ctrl+S pops up the Save Page window and (if I held Ctrl+S for more than a split second) it crashes (probably due to multiple popups becoming unresponsive). The mouse can't click to cancel the pop ups for saving the page nor interact it. I have to kill the firefox process and restart it. I've been looking into disabling Ctrl+S shortcut in Firefox with no success (extensions are deprecated or require too many permissions I'm not comfortable with).

Would someone help me to disable Ctrl+S or enlighten me on how to not have firefox crash every time I accidentally press Ctrl+S?

Thanks!

Firefox eventually crashes every time I use it, usually when there is about 165 mbs of data. I can relaunch it by both using CCleaner to clear the browser in addition to going to Firefox preferences and deleting data and history. I don't have Flash or Silverlight. I have refreshed Firefox a number of times and completely uninstalled it using the MacCleaner Pro App Cleaner and Uninstaller and reinstalling it using Mozilla's online download link.

I have an HTML signature that seems to work nicely when I compose a new email, but when I reply back to somebody who has replied to said email, my signature sometimes falls back into plain text mode, looking like a complete jumble. I get around this problem by copying the original signature and just pasting it in my reply.

A few key notes; - Account setting is set to use HTML as default, and it does. - The reply I get back still retains and displays the original HTML signature. - When I hit reply, that first HTML signature is still there, but the new signature is in plain text.

So to summarise; It's not processing HTML above the reply line, only below it.

Is there a way to absolutely force the composer to use HTML all the time everytime?

I had to shut down with the power button. This is the first time it has done this way. I have the gz files EASE HELP DONT JUST TELL ME NOBODY ELSE HAS THIS ISSUE.

Hello,

The logo on this page I'm creating isn't showing in Firefox. It's working fine in other browsers.

When I inspect the logo url is there but not sure why it isnt showing.

When I try to access MediaFire it doesn't load and get errors etc. And other sites are slow etc. Is there anything I can do to fix it? Also how do I contact FireFox email official support? I don't like asking on the forums since I want a legit agent ;p

Logged into https://www.expedia.com/ the home page tries to open but a second or two later I see a blank, white screen. I "Turned Enhanced protect off" Expedia page still blank I open GOOGLE and Expedia works perfectly

with version 91.9.1 (32 bit) it takes 12 to 14 seconds to send an email - same on 4 computers 3 windows 10 and 1 windows 11 this started 5/22/2022 after Thunderbird update

I have a lot of issues with my mailbox. Constantly have to repair folders because the wrong subject shows on the wrong email. A big one I had was my inbox getting bogged down, but I learned it doesn't like to have more than a couple thousand emails in it. I kept getting a "exceeded maximum number of connections" error but read something about too many folders, got rid of a few folders and that error went away.

1) What other kinds of tips are there for keeping TB behaving well? 2) I see that my profile has a lot of old files for old folders that don't exist anymore. There's also nstmp files and foldercache.json files. Should I delete all these types of things to clean up? Or should I just start fresh with a new profile and re-download all my email messages? I can't imagine how long that will take because sometimes folders download quickly but other times take forever and I'm not sure the difference. I just downloaded a 4000 email folder in a 20th the time of another 2000 email folder.

Avast flashes the attached message [Avast has blocked access to https://incoming-telemetry.thunderbird.net/ because one of the issues of the server certificate has expired.] Avast suggests a work-around. Is this something you are planning to fix [updating a certificate perhaps] or should I implement the work-around suggested by Avast? THANK YOU SO MUCH!

Dear Support-Team, since a few weeks, I cannot start firefox anymore. I already deinstalled and installed a new downloaded version twice. But it keeps crashing, as soon as I click on the browser icon. Does not start at all. Those are the crash ID's: from 31.05.: bp-9b62d284-cfd8-4ec0-8df1-dae7e0220531 from 11.05.: bp-8612c900-a4c9-4334-93b5-f17890220511 from 09.05. bp-0b6e46a9-a0d0-4951-bd62-5f8fe0220509

Any idea what might cause the problem? Thanks for your help in advance, Kornelia

Every time I turn on my computer Firefox wont open until I open Chrome at leats once, after I open Chrone I have no problem I can close it and continue to work in Firefox, but it is still a weird problem, I have also uninstall and reinstall Firefox several times but it doesnt fix the problem.

I am unable to open firefox and am currently typing from edge (yuck). I believe it is crashing on startup, it does not open when I click on the icon either pinned to my taskbar or through the start menu. I have reinstalled the latest version to no avail. If it is crashing on startup then it is not generating a unique crash report each time; my last report is from last night when the problem started, Crash ID: bp-f8bfbf97-971a-464b-8930-aec7e0220530. Many thanks for any help.

I've tried everything, including setting it to filter an empty folder instead of my inbox. But it still defaults back to filtering the inbox every time it restarts. I'm trying to stop filtering to debug why my email keeps hanging. I have 800 filters so I don't want to uncheck 800 boxes. There should be an option to turn off filtering temporarily, or to uncheck all the boxes at once.

Firefox version 100 was working fine, but after I upgrade to the version 100.+ it only displayed a blank page no matter what website I visited. I downloaded the 101 Beta it worked perfectly. However, when I installed the official release V101 yesterday and it stopped working again. I reinstalled the Beta version 101 and 102, both worked perfectly. Why only the beta version is working, but not the official release version?

Regards,

Hi, since we have installed Version 100 (100.01 or 100.02) we cannot open the Settings or the AddOns / Themes page. Nothing happens. Also the "about:config" dosn`t work. On the other hand, it works fine, when we are in the trobleshoot mode.

We have no policies There is no policies.json Same Prolem in x86 or x64 Version

We have no idea, where the problem can be

Greetings Manfred
