It works pretty good for my use case. Just read the longer 5 star review in this thread and follow their direction, and it should work for you too.

Is mSession Keeper Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
mSession Keeper requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
