Find a generic way to disable extensions on security critical websites (e.g. banks)

[karlicoss]

Since extension is sending urls to the backend, it's potentially not secure to do so on websites like banks. While extension supports blacklisting it's not really great to rely on user to do so.

Perhaps some of these lists https://github.com/cbuijs/shallalist would be a good start, unclear how often is it updated though.

Also need to add a UI explanation if the link is blacklisted; and an option to whitelist urls from the 'default' lists in case user really really wants it.

adblock lists could be helpful?

I've gone with couple of builtin shallalist filters https://github.com/karlicoss/promnesia/tree/master/extension/shallalist

But would be nice to

• download it dynamically
• autoupdate
• generally this is ought a library or something, so many extensions could benefit

I guess this is pretty much done here.. #156

Just need to add a disclaimer to readme about what data is send to the (user-running, ideally local, but still!) backend and when.
