Manifest v3 notes

[lukaw3d]

Updated timeline:

• Jan 2023: may turn off MV2 extensions in Chrome Beta
• Jun 2023: MV2 extensions unlisted, may turn off MV2 extensions
• Jan 2024: no more updates to MV2 extensions

TODO

• can redux + saga even continue to work despite terminations
• fork webext-redux New extension webext-redux issues #1052
• keep wallet unlocked between terminations by storing encryption key in browser.storage.session
• check how badly ledger breaks if user waits a minute before confirming a transaction (service worker terminates after 30 seconds?)
• https://chromestatus.com/feature/5200265459269632 webusb doesn't even work in MV3 service worker yet
• Opening extension as a new tab and storing state in it would solve some of these

key point from bitwarden's article:

https://developer.chrome.com/docs/extensions/reference/api/storage#property-session

new "session" storage area is where to put "in memory" keys. in their case, a key that encrypts a locally-encrypted copy of the vault persisted in localStorage

If we don't plan to have dapp support (#1901) then we could:

• move redux from background page into popup
• store derived keyWithSalt in chrome.storage.session
• remove background page / service worker
• remove webext-redux

(So ext will behave more like webapp tabs. At some point we aspired the opposite: webapp tabs to use a shared worker to behave more like extension)

not aware of anyone using dapp support

https://www.npmjs.com/package/@oasisprotocol/client-ext-utils

apparently this package has 3 downloads weekly though
