is there a particular danger to run alby browser extension on a computer linked by ssh to a raspberry pi running bitcoin core ?
This sounds like you have a hot wallet, I wouldn't recommend having more than a small amount of BTC on any computer connected to the internet.
If you only have a small amount then it would be fine to run alby (which I think it's a reputable extension anyway).
If you have more than a small amount, then transfer that to cold storage.
To put it even more simply there is always a danger of having ANY funds that are accessible by ANY device that is online.
Phone / desktop / whatever.
Yes, your installation of core might be safe. But is the PC that has this extension installed gets infected and someone gains access to that machine. Then they can do whatever they want on your network.
