Mixed content over https on Joomla. Have a plugin?

Question

Joomla

Connected an ssl certificate to two sites on Joomla - I came across the problem of "mixed content" (mixed content), when some of the links on the page still contain addresses with http.
Moreover, such links do not come from articles, but from all sorts of plug-ins and modules.
You can, of course, comb modules one by one, but what if there is a plugin that automatically changes links on the fly??
I tried to search in JED, but there the search is surprisingly horribly implemented.
