Nice for those needing eye candy.

Once the nature of things get more important than the packaging, the attentions turns to what is under the hood and its real function and objectives.

we start at the homepage of arc. where i first landed when i first heard of it. i snatched a download and started analysing, the first thing i realised was that arc requires an account to use, why do they require an account?

That is a biggie nono right there, as your privacy is immediately compromised.

so it looks like arc stores some preferences in firestore, along with a basic user object, referrals and boosts

Bigger nono.

*arc boosts can contain arbitrary javascript
*arc boosts are stored in firestore
*the arc browser gets which boosts to use via the creatorID field
*we can arbitrarily chage the creatorID field to any user id

Very, very bad.

Although it may have been and may be plugged, the main concerns remains the same.

If you want to use an app, use a mobile device. If you are privacy and anonymity oriented, stay away from it.

OP, glad you found something you like, but imo your recommendation is not fit to meet my security needs.
