I use a few (trustworthy) extensions on my work laptop, including an ad blocker. I think that overall this is a good security (and quality-of-life) choice. However, I'd like to minimize the number of extensions that run while I'm on work-internal sites (no ads or security risks there).

Is it possible, in Firefox, to prevent extensions from running on a specific site?

I, like many others, am suddenly working remotely, along with the rest of my company. My employer has a VPN for remote workers, but it's swamped with all the newly remote employees. Therefore, I'd like to know what will (and won't) put unneeded strain on the VPN. Obviously, downloading a file or running an SSH session to a server within my company's private network will put traffic across the VPN. If I'm streaming music on Spotify as I work, from the same computer I'm sshed in on, will that put more traffic across the VPN? Will (public) web browsing do so?

Or does this all depend on how the VPN is configured?

I have a decent background in discrete math / CS, but am currently doing work which requires formal logic chops (esp. substructural logics), a subject I have no prior experience with. Does anyone have helpful resources (preferably textbooks) to learn the basics?

I'm studying / doing research in computational biology at university, and realized that I'd like to know more about how drugs and poisons work. Unfortunately, my school doesn't have any courses in pharmacology or toxicology (the closest I've gotten is some biochemistry). Can anyone recommend some resources for me?
