Firefox started to restrict which ports it can connect to. A Firefox user trying to connect to the Conky by HTTP on the default port would get this message:

This address is restricted
This address uses a network port which is normally used for purposes other than Web browsing. Firefox has cancelled the request for your protection.

With the only option to "Try Again" which wouldn't work.

Enumerating all the proxies in a doc would be nice! There are so many. Even if it happens in the doc str of the method, that is fine. Else, we may need contracts.md userguide (in docs/userguides). If you go that route, you don't have to thoroughly create it, just initialize it, add the enumeration, and we will fill it in later with non-relevant details to this PR.

There are multiple places in the code where we use an account address as the key of an object/mapping.

If a same address can be valid on multiple networks at the same time, we should make sure to also index the network name in the key.

The relationship between these 3 types isn't very clear from the documentation, and conversion traits between them don't seem to exist as one might expect (plus iterator conversions may also be useful?). The LogLevelFlags docs even mention log_set_handler and log_set_fatal_mask, which confusingly both take a `LogLevels

We should probably catch this error in TestCollector and handle nicely
Replicate:

struct VoterInfo:
    # 1 yes / 0 no
    member voted : felt
    member allowed : felt
end

@storage_var
func voter_info(user_address: felt) -> (res : VoterInfo):
end

func:
    let (voter) = voter_info.read(111)
    assert voter.voter_id = 3 # it crashes HERE

The influx DB line protocol is described here: https://v2.docs.influxdata.com/v2.0/reference/syntax/line-protocol/

It would be great to have a python adapter which can handle this line protocol and forward the data to the lognplot gui.
