You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

After the above;

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Will you keep us posted  ? Cause if Coinhive doesn't turn out to be the "culprit", we'll have to keep looking ....

I think it was surely coin hive..when i load all the page that blank white i try view the source and all is the same..and also i think the script file is loaded from the profile file..cause my thunderbird also detected by WDS infected with coin hive..

I try to run WDS offline scanning.. and after the restart and scanning..the problem seems to be gone for now.. without need to install any addon or malware scanner ..
