The new LP 4.9.2.0 version is working again with Firefox ESR.. good..
but I noticed that with LP active when browsing protected https urls, the browser becomes too slow (almost freezing) and the CPU goes high..

As soon as I disabled LP the logging in and browsing over https urls websites became fast again as it should be..

This time I voted 2 stars,... in the past this was for me a 4-5 stars extension
