No, I don't find any electrum wallet that supports Chromebook OS as of now only 4 OS are supported. Linux, Windows, OSX, and APK or android OS.
What i want to know is, there are no issues downloading electrum or electroncash on a chromebook if you download linux on it correct?
If your OS is linux yes you can download the electrum and install, but if you download the electrum as chromebook os it's not a compatible OS.
Another thing i thought about. But since nano ledger s uses google chrome, does that mean i could actually use the nano ledger s with it?
I don't think ledger nano could be detected in the chromebook OS because I think it needs a driver first to able to detect the device.
The thing thought is im using it with my windows laptop. The thing is this chromebook will be used to stream sites such as tv shows and cable tv and thus if any virus i get on this computer, i don't mind as i would just wash it as i believe thats the term for chromebook. Thus its possible to get a virus from a windows computer if you are not sure of that site when streaming. However since its a chromebook, there should be no issues with it right? And even if somehow the chromebook get a virus which i read is hard, then its still safe to connect the nano ledger s into it right to move your btc or access it with the nano ledger s?
Everything could be possible we can't guarantee that the google chrome book OS is 100% safe. Look at the MacOS they said before that this OS is safe, but right now they release an antivirus due to some people experience malware and viruses.
You can try to test it first if you had your ledger nano you can test it now then if your nano is detected might be the ledger wallet in chrome browser will work, but the electrum will not work.
