Clearly your signature is a table. Those red lines are the borders of cells in a compose situation.

I guess the pasted objects have the border of cells drawn in and not left to be blank as it the case with your signature. I am also guessing you have no space line between the signature and the table, so they are running into a dingle table when pasted.

Obviously the solution is to have a blank line in the first thing in your signature, or until you fix it ensure there is a blank line in the body of the email between your signature and the point where you paste in your table, before you paste obviously.

Perhaps create your signature using the instructions on this web site and not copy a table from one of the word processing programs (or some website) which is probably how you got your signature in the first place.

Thank you for your response! Unfortunately the problem isn't spacing, there's lots of spaces and lines of text between the cells I'm putting in the email and my signature.

Also unfortunately, I didn't create the signature - I was given html code by my employer to use for it, so there is consistency company-wide. It works fine in Outlook and Gmail, but I was going to give Thunderbird a shot.

I'll keep looking for solutions!

Thanks again.

re : It works great when I just compose and send a message. The signature looks kind of weird on my side before it sends - It outlines the boxes separating the individual HTML components in red - but looks perfect to the recipient.

That is normal. It means the code you used for the signature was designed in a table and the composing 'Write' window is designed to edit / create emails and therefore you would see signature as if in edit mode. This does have the added bonus of being able tro edit on the fly if ever necessary.

When you paste in copied cells then you are also including a load of MS formatting which is also effecting the signature. Sounds like both tables were created using MS product and therefore you are inserting code in top table which overrides whatever is in signature.

Is there a signature delimiter -- above the signature separating it from content?

re: I didn't create the signature - I was given html code by my employer to use for it,

Have you considered using Thunderbird Write to create identical signature ?

• Open Write
• Completely clear all contents.
• press enter a couple of times to create two lines of space.
• Insert > Table
• Set up rows and columns you require to match original singature.
• Enter data into various cells and format as required to match original signature.
• Then save as html file and set to use attached file in Account Settings

If you want - you could send an email to me which contains the current signature. I could then use it to create a html signature file using Thunderbird Write and you could see what it looks like as I would reply to you using it. My email is: mail at anje dot co dot uk That is phonetic to avoid spam bots, so 'at' means @ and 'dot' is a full stop/period Enter 'Test signature' in the subject so I know it is you.
