Copying lines from My Filters to outside issue

[Wakagithub]

Copying multiple lines from My Filters to the outside so far doesn't work, like to an editor like Notepad. Already tried these below:

• Firefox' Edit, Select All, Copy.
• Firefox' Edit, Select All, right mouse button, Copy.
• Left mouse click to put the cursor in the My Filters area. CTRL+A. CTRL+C.
• Left mouse click to put the cursor in the My Filters area. CTRL+A. Right mouse button, Copy.
• Left mouse click to put the cursor in the My Filters area. Right mouse button, Select All, Copy.

Possible results to the outside after pasting:

• Only the last line is pasted.
• The previous clipboard content is pasted form whatever it originated from, not the multiple lines desired from My Filters.
• Nothing is pasted, or just a middle dot (a unicode middle dot?).

These related action(s) work:

• My Filters accepts and saves one or many lines from the outside. Like say after I sorted the lines alphabetically and auto-removed duplicates with an editor.

My versions:

• Firefox 78.0. I'm still waiting a bit more for possible versions higher than 78.0.1, to save internet data.
• Nano Adblocker 1.0.0.148
• Nano Defender 15.0.0.200
• Windows, 64 bit

Related:

• Such issue is nonexistent in uBO, in the same Firefox and OS. I never experienced such from my very first usage of its own My Filters.
• The very first time I tried to copy from Nano's My Filters, the issue was immediately there. I can't remember how many versions back when I first ever tried to copy. The issue was already there back, way below Firefox v78.0. I just ended up using my workaround below.

My workaround:

• From My Filters, Export. Then open the exported text file with for example Notepad to get its contents.

Thanks in advance, and more power.☺

I cannot reproduce. May you sure you are using default and fresh new Firefox profile?

If you still have the issue with new Firefox profile, either upgrade your version to test again, or report me then I will try it on 78.0 for you. Also, Do your Windows mean Windows 10?
