106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

I am using TB 31.7.0 on a MacBook Pro running the latest version of Yosemite. I use BusyCal as my calendar software (although I think that is not relevant to the problem I am experiencing).

When people send me an email with an ICS meeting invitation attached, the attachment does not arrive. I get the email but there is no attachment. So I always have to send a reply and ask them to manually type the meeting details into an email, and then send it to me. It appears that this problem occurs when meeting invitations are generated with Outlook. (That's a guess on my part.)

I've read through the forums to try to find a solution to this problem, and I haven't been able to find it.

Any suggestions?

Thunderbird will not connect to my bt mail. I have tried Mailbird, Outlook and others and they will not connect. I have checked configuration with BT and they say all OK. Have changed password - no change. Manually configured with password - no change. My PC has had a new SSD since and still will not connect. I have Broadband with BT so I get the same privaligies as Premium. I have malwarebytes and that allows them to connect. Up until a couple of weeks ago it worked OK and then suddenly it stopped working. Had my local Techie shop look at it - no result. They said it must be BT, but spoke to them again today and they say it should work - certainly with outlook. They recognise connection, but says either config or password incorrect. Changed password again, but no change. Can you please tell me where the problems is. Thanks

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I have Thunderbird Version 45.8.0 where after composing a message when I click Send, the message disappears nicely from the screen and the message is off.

However on the latest version 52.1.1 (32-bit) when I do the same action, Click to Send.. the message stays on the screen for a while and I have to wait for it to disappear before I can do something else.

Is this a case of different versions or is there a tweak in the new version that I can set up in order for the Send function to behave the same way as the older version?

It is getting quite annoying sitting and looking at the screen for the message to disappear after clicking Send.

Thank you for your help.

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

Can receive but unable to send emails - SMTP - AUP#out-1500 Thunderbird version 115.4.1 Windows 11 Windows Defender Spectrum provider - Can send messages when I go to Spectrum site on internet Copies of account settings attached

After switching to Firefox version 123, I encountered an error on our website: '1,000,000.00 is not a valid number.' It seems to be a form validation error, but it worked fine with previous versions of Firefox. The application is built using GWT (Google Web Toolkit). Any help would be appreciated. Thanks.

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

My Thunderbird V115.3.3 locked up today and after 5 different tries, I used the safemode option. When I exited safemode, (1) my calendar is missing, (2) the hamburger menu does not work, (3) can't install any add-ons, (4) Settings does not work (but account settings does), (5) mail toolbar is missing, (6) profile manager does not work plus other things

How do I get things working again.

I need to mention I using the Portable version of TB V115.3.3.

Thanks

Something is going on with Firefox. Web pages will not load, and the error message is "we could not verify the certificate: reason = timeout".

My internet speed is 400Mbps. I don't have a delay here. I've rebooted the PC, restarted Firefox, and about 3 out of every 5 web pages comes up with this error.

I couldn't even get to the Mozilla support site with Firefox. I had to use a different browser.

What's going on?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Made a mistake and installed 157.7.0 on Linux

Now cannot backup/restore to another computer so cannot use that computer.

Old Profile used to be in .thunderbird folder - easy!

Now profile seems to be in /home/oem/snap/thunderbird/common/.thunderbird/26pphmrb.default

This does not contain all emails especially for pop3 and anything after Nov 23. It does not work

Q's

Best way to fix? Can I force it TBird to read the .thunderbird in home directory? Can I install an older version of TBird easily? Is there some other way to restore the profile and clone another computer?

I currently have Thunderbird(TB) using POP with a hosted email provider(HEP) with my own DNS. I am going to transfer to a different HEP where I am told I can keep my current mail address/name . Is it possible for me to continue using my current folders after I transfer? My searches have come up with various responses for an IMAP setup but I haven't been able to find anything for my POP setup. Could someone help me with this please?

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.
