All the options are working as intended for me except the EXP multiplier. I tried to confirm this by gathering herbs with and without the EXP multiplier activated, and there appears to be no difference in EXP gain; either way, I only gain 7 EXP each time.
if you notice the XP multiplier does work but its for your stats column not your skill column it multiplie xp for strength valtility and all but not for lock-picking and alchemy
Can confirm, the multiplier only effects the primary stats (Strength, Agility, Vitality, Speech) and will not work for combat or skills.
Fixed my issue. Was able to install Chrome and download the trainer there. For some reason Firefox is flagging CH as a threat.

I'm running FF 58.0.2, have Deceptive Content and Dangerous Software Protection enabled completely in Privacy & Security -> Security and have no issues whatsoever with our site.
Maybe it's not FF but your interfering security software because either our website is not whitelisted/ excluded and/or your security software uses a script or browser add-on to hijack and crack the HTTPS traffic in the browser to monitor it for possible malware.
