Thunderbird Community Forum

Good morning,

I am requesting assistance for a recent problem I have encountered sending attachments with email messages I am sending. There is no problem with sending the message itself. And have noticed no problems with receiving messages. When I attempt to send an attachment with a message I am sending, a click on the "attach" icon in the upper right-hand corner of the email screen, provides no response. I didn't notice a problem with this function in past weeks.

I appreciate your assistance. Thank you.

When writing an email and i try to press attach button, nothing happens and i cant attach file that way. Drag and drop works. This came after updating thunderbird to latest versio 157, earlier attach button worked fine. Any solutions to this problem?

In Thunderbird, the “attach” button stopped working when sending a message, although the “drag and drop” feature still works. Could you suggest what the problem might be?

I use Thunderbird for email. Suddenly I can neither attach nor insert files/photos into an outgoing email. Also, keyboard shortcut ctrl+shift+A doesn't work and is greyed out. I have no extensions and troubleshooting mode doesn't work either. What's wrong?

Suddenly I can't attach images (or anything) to outgoing emails. I do this a lot and it worked fine all day yesterday, then stopped in the evening. When I click the Attach button, nothing happens. I've deleted 1000s of emails and compacted the folders, nada. My Thunderbird is up to date v153.4 on Win 10. Any ideas? Thanks, Andy.

You Know!!! This is not uncommon. This is the first time for me. I've removed the Open as Admin... Off & On. Total BS that this isn't a top issue when I come here. Lousy support. I need to go elsewhere.

The attach button is not working on new emails. I've been dragging files into new emails as attachments. Thunderbird version 157.0.1. When will this bug be fixed? Thank you Norm

I can't get an attachment to an email message. When I select the 'attach' button, nothing happens. I recently cloned my C: drive and am concerned that something didn't get cloned properly

I received an email and when I responded to that I need to attach a document. I was unable to attach it. I went to another email and it also would not attach any document???

Just recently, the "Attach" button in the top right corner of emails in Thunderbird has stopped working. You can click it but it will not open a window to select a file to attach. Similarly, the yellow reminder bar will not allow attachments to be selected.

However, it is still possible to attach a file by dragging and dropping from an open older in Windows Explorer.

The version of Thunderbird I am running is Thunderbird 153.4.0esr (64-bit) [showing as up to date] running on OS Windows 11 Home Version 25H2.

I tried removing the button and then reinstating it (a fix suggested online) but this had no affect. I also checked in properties that the Run as Administrator box was not ticked.

Another fix suggested on line was to rename the file xulstore.json as xulstore.json.old, but this did not solve the problem either.

Any help in solving this problem would be appreciated. Thanks.
