Please explain what you're doing in more detail.

I get like in the screenshot 1 instead receive as screenshot 2

What are you trying to achieve in the first place?

Extensions should update automatically, without user intervention. If you want to see your installed extensions you're looking at the wrong place.

At the top right of the Thunderbird window, click the menu button > Add-ons > Extensions.

OK . Leave it this way. Thank you very much.

What language is that?

Hebrew

I am wondering if we might have an issue with Hebrew, I saw someone else in the forum today were Thunderbird wax messing up Hebrew folder names (in the file system).

Did Thunderbird just update?

Yes, I have Thunderbird recently updated to version 45.2.0, but this problem was also in version 45.1.1

I suggest you try V38, just to be sure it is not some sort of regression that has occurred in the 45 line.
