LibreOffice Version: 6.4.6.2 (x64) paste is greyed out

I’m trying to paste from webpages in Firefox to LO writer. OS is Windows 10 Pro. The first paste works, subsequent paste attempts, and the paste is greyed out and cannot paste, sometime ctl-v does not work. I have to close the document and reopen the document to paste each subsequent item. I would appreciate some help.

do you have any clipboard manager?

I do not have a clipboard manager, would that help or hurt?
