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?

No way to ASK a question in the Monitor section, there is no GET HELP button.

Application error: a client-side exception has occurred (see the browser console for more information).

In general, getting to the "ask a question" button in the support website is like finding hens teeth.

Didn't there used to be a Discussions forum, where you could see all of the questions being asked?

I can't receive emails at any address from those in Thunderbird. I have several addresses, some in Gmail but not all. And in each of them I get this message: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials. I am using version 115.5.2

Cox.net is transitioning from in-house e-mail to e-mail handled by Yahoo.com. Our cox.net addresses are supposed to (and apparently have) transitioned so that they still work, but are processed through pop.mail.yahoo.com.

It is my turn to be transitioned and I have been successful in doing so to the extent that I can send and receive using my address(es) ...@cox.net through Yahoo web mail and on my Samsung phone. I have not, however, been successful in either sending or receiving mail using Thunderbird on my desktop.

I have been successfully using Thunderbird with POP settings for years with four different cox.net addresses. [I'm currently just trying to get two of them working -- unsuccessfully.]

I am using Windows 10 on a Dell desktop. I am using Thunderbird 115.9.0 (32 bit). I have reset the POP and SMTP settings as directed by Yahoo. One of the errors I receive is: "Error with Account .... Sending of password for ...@cox.net did not succeed. Mail server pop.mail.yahoo.com responded (SYS/TEMP) Server Error - Please try again later." It then asks me to retry or enter a new password. I have checked the passwords saved by Thunderbird and they are correct.

I suspect, that with all the Cox accounts being newly routed through Yahoo servers that I am not the only Thunderbird user experiencing this problem. Does anyone have any suggestions? Is it likely to help if I uninstall and reinstall Thunderbird? Would I loose all my mail, etc. if I did that? [I did the delete and add account in my phone and that was successful, but I wasn't concerned about losing mail there as it is all on my desktop.]

Thanks in advance. billb1111

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

Somehow my Thunderbird email password was changed and I didn't do it. How do I reset my password? Email [edited] @sbcglobal.net when or if you have an answer. Thanks.

I've provided all of the other data, no problem. But the <Your login> field has only "YOURDOMAIN\yourusername" in it as a format hint. The field carries an Info symbol, but it's greyed out.

There are many possible domains, e.g. microsoft.com, office365.com, outlook.com, each with possible 3LDs, and the domain-name of the organisation that provides my account.

The most obvious (MYORGDOMAIN\Roger.Clarke) gets the error-message: > Authentication failed. Please check the username and password. (I checked, and they're the same as I use for a webmail login there).

Leaving it empty gets this error-message: > Unable to log in at server. Probably wrong configuration, username or password. (That about covers the possibilities then ...).

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.

The last couple of weeks I have this pop up interrupt my screen quite often several times in a row.

I have searched every article online that is remotely similar to this problem and none of the solutions have  worked. 

Any ideas on what I can do to stop this annoyance?

I've been plagued with incoming messages that use a foreground/background color combination too dark to read without forwarding the message and then applying white to the swept text. The uploaded image shows the progression of reading the message, sweeping the text in the message (still uncomfortably dark with low contrast), forwarding the message (still unreadable), then select the text and apply white as the text color. I've googled this problem to no avail as most hits are for color contrast in the inbox format for color.

One solution is to switch themes from "dark" or "system theme - auto" to "light" then Thunderbird switches to black text on a white background and the incoming message is readable.

Is there a setting I'm missing to automatically solve this without having to swap theme's to read a message then swap back to preferred dark mode?

I have a hotmail.com address. Until recently, it worked well as webmail, plus also from TB on laptop, via IMAP and SMTP.

A few days ago, the sending function via SMTP stopped working (not IMAP); and webmail is still fine. I've tried a lot to solve it, but to no avail.

My guess is that MS is to blame, but don't know how to reach someone better-than-hotline there.

Details see annex; OS is Win10, TB is 115.9

Would someone be familiar with this kind of problem? According to my traditional european quality idea, best should be to get in touch with an MS technician with access to the syslog, to hear what the system's response to connection attempts is - but this seems to be precluded? I wonder what alternatives there might be?

I have an add-on ad blocker for youtube and have never gotten ads. This afternoon that stopped. I get ads with every video I click and there is no 'skip ad' on the screen. I added another top rated youtube add blocker, quit firefox and then opened it again. Before, if I clicked a video it started an ad and I could go back and then hit the video again, but now that doesn't work, but if I select to show the video in a new tab, there are no ads in that tab. What can I do to make the ads stop like they used to and never appear? Yes and my OS is Ubuntu 22.04

Hi all

After upgrading to 115 (Linux amd64), messages are no longer marked as read when I delete them before they are marked as read (either automatically or manually). I have (and have had for many years) set "When I delete a message" to "Move it to this folder" -> Trash on (Name of my IMAP account). Before the upgrade, messages were moved to the Trash AND automatically marked as read when I deleted them. Now, they are moved to the selected Trash folder, but left unread, and the Trash folder gets displayed in bold, together with a number counting unread messages in it.

Is there a way to get the old behaviour back?

Thanks and best regards /m

When composing a new message (in other words, not replying to a message) I want them to always show the default email address, the one corresponding to the top account. The field "Outgoing Server (SMTP)" shows (Default), and ordinarily it works fine, but occasionally it will use one of the other email addresses. In reading your responses to other questions I've seen that the default address is only used when TB can't figure out which address to use. Is there some way I can tell TB to ALWAYS use the default address when composing a new message?

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

I accidentally deleted a fairly large email, namely 3GB in the Thunderbird application, but when I checked in junk/trash the deleted email didn't appear. When I checked locally there was a file called Trash (no file format) with a size of around 3GB and in it there was an email which I deleted previously. How do I return the email back to the inbox?

Hi! the last version of thunderbird (115.4.1 on Windows 10) don't remember the last mail selected when I change the folder. I try to explain better, for example if I go to the inbox and select one mail (for example the last mail received), if I go to another folder and then go back to the inbox folder the view is another one and I have to scroll down to find again the last mail received. I 've the same problem on my office computer so I think it's a problem common... This issue is come since I installed the Supernova versions.... Thanks!

ps this problem seems to be present only in the inbox folder if the last message received is in the bottom (mail from the oldest to the newest) If I change the sort with the colum date to have the last message in the top (mail from the newest to the oldest), the problem disappear

I received the latest update to v. 115.4.1 and after admiring the new look, I discovered that I could not open any type of hyperlink within an email. Right-clicking and selecting 'open in browser' fails to open the link as well. This was never an issue until this update. I am on a Win 11 desktop with Chrome set as my default browser. Please advise - I love this tool!
