Hi all;

I have an odd issue with Firefox & Windows 10, with accessing HTTPS websites.
The sites are very very slow to load and others do not complete the load cycle.
I've had this issue for months now.

Just tried the newly released Firefox v50 ... same issues.
Also use Portable-Firefox:
-On the Windows 10 pc = https sites load very slow.
-If I move to my other PC (using Vista), all sites load fine. Without any changes to my Portable-Firefox setup.

When I use Microsoft's Edge browser all sites load fine.

There seems to be a conflict between the Toshiba Laptop, Windows 10 & Firefox in loading HTTPS websites very slowly.

This is what I have tried so far in relation to Windows 10:

-Changed Proxy settings (within Firefox) to each setting
-Flushed DNS cache
-Checked HOSTS file for any entries to those websites
-Removed entries from Windows Firewall
-Disabled Firewall and Anti-Virus
-Checked for Malware,Spyware,etc,etc
-Booted into Windows 10 SafeMode-Network Enabled


My head is getting sore now. Any suggestions

As I mentioned my Portable-Firefox installation works fine on other pcs, including Windows 10 versions, but not on this system (Toshiba laptop & Windows 10). Though MS Edge browser works perfectly fine.


Some of the https sites:

https://au.yahoo.com/?p=us ((loads very slow, with some pics & videos not loading at all. even news articles not loading at all))
https://www.youtube.com/

[always waiting for i.ytimg.com & s.yimg.com]

Yahoo mail & Gmail are extremely slow
