Waterfox: Storage Standard: browser.storageManager.enabled and dom.storageManager.enabled

[grahamperrin]

Consider changing the defaults from false to true for these two preferences:

• browser.storageManager.enabled
• dom.storageManager.enabled

Background

Storage API - Web APIs | MDN in particular Browser compatibility note 3:

The Storage API is implemented and enabled by default in Firefox 57.

Storage Standard

A series of four results in the _web-platform-tests dashboard_ for WPT / storage:

1. https://wpt.fyi/storage/?sha=b0c75cd885 including Firefox 56.0
2. https://wpt.fyi/storage/?sha=0860fcb11e including Firefox 56.0
3. https://wpt.fyi/storage/?sha=b467fe0c0b including Firefox 57.0
4. https://wpt.fyi/storage/?sha=e511e5e8af including Firefox 57.0

The great difference, for Firefox, between (2) and (3) was probably due to browser.storageManager.enabled and dom.storageManager.enabled being false in Firefox 56.0.

The most recent result:

• https://wpt.fyi/storage/

Some Mozilla bugs:

• 1147820 - [meta] Improve Storage
• 1254428 - Implement Storage spec
• 1286717 - Expose persist/persisted method to StorageManager RESOLVED FIXED in Firefox 55
• 1354500 - Remove the proprietary persistent indexedDB permission
• 1421690 - (storage-v2) [meta] Storage (Site Data and Cookies) Management V2
• 1428306 - Investigate removing browser.storageManager.enabled pref

Storage Standard is mentioned in (not the focus of) two W3C documents:

• Clear Site Data
• Permissions

Indexed Database (IndexedDB)

Indexed Database API 2.0

https://wpt.fyi/IndexedDB

Plus today I stumbled across a post in mozilla.dev.platform, Intent to unship: "storage" attribute in options for indexedDB.open() - Google Groups (2018-03-06), which described Storage Standard as a web standard that

specifies a better persistent storage mechanism and has broader vendor support

From another point of view (specially security or privacy), I won't recommand this change.

C:\Users\WagnerGMD\AppData\Roaming\Mozilla\Firefox\Profiles\6x9jwr02.dev-edition-default\storage\default\https+++www.youtube.com^firstPartyDomain=youtube.com\.metadata
C:\Users\WagnerGMD\AppData\Roaming\Mozilla\Firefox\Profiles\6x9jwr02.dev-edition-default\storage\default\https+++www.youtube.com^firstPartyDomain=youtube.com\.metadata-v2
C:\Users\WagnerGMD\AppData\Roaming\Mozilla\Firefox\Profiles\6x9jwr02.dev-edition-default\storage\default\https+++www.youtube.com^firstPartyDomain=youtube.com\idb\3211250388sbwdpsunsohintoatciif.sqlite

Because I'm wonder how Youtube was able to create these cookies ? It can't be ?

lockPref("network.cookie.cookieBehavior",2);
lockPref("network.cookie.lifetimePolicy",2);
## Because I had decide to block the cookies (I rather to define my own list of exceptions).
## At the contrary, it's a trouble since Firefox_v57 (the damn idiot at Mozilla sic... Because they forgot to provide one API (allow Cookies Exceptions) for WebExtension)

Well the answer seem's to be related to :

pref("dom.indexedDB.enabled",false);
pref("dom.storage.enabled",false);
## Open the Web Console (from the developer tools), you will see one message such as : "A mutation operation was attempted on a database that did not allow mutations" (etc)

But there is a bad point because (as you can see on this picture) sometimes it will break a website (protonmail.com, mega.co.nz, etc)

PS : Another reason : no it doesn't seem to exist. No we don't have any good addons to control the both (switch on/off).
According to my memories, the last one was Shim Storage and it will need to be replace and improve (Cookie Keeper seem's to be also abandon (no news features)).

HS : Which post it was ? Nevermind because by the past (with Cyberfox under Windows), it has never help me.
pref("memory.free_dirty_pages",true);
Perhaps there is a difference related to the OS (FreeBSD, etc) ? I ignore but I had try several times and the result was always the same (none improvements).
In fact, the memory was improve a little when Firefox_v56 was published. And It was even better after with Firefox_v57 (aka Firefox Quantum) but I imagine it's might need again a fews improvements.

Thanks, I'll continue testing (I set both preferences to true a few days ago).

If I understand correctly, one of the apps that I use might switch to Storage Standard because of problems with IndexedDB.

[grahamperrin]

pref("memory.free_dirty_pages",true);

@WagnerGMD there's a separate issue, 423:

• memory.free_dirty_pages in Waterfox 56.x

… how Youtube was able to create these cookies ? …

This issue is primarily about browser.storageManager.enabled and dom.storageManager.enabled

[WagnerGMD]

I had try a few times but on the moment, I don't why I wasn't able to find it.
Thank you @grahamperrin, I will keep it (add to my bookmarks).

@MrAlex94 Any update to this? Seems that's uBO webext uses this also, if it's enabled, then it shows how many storage is used.

[MrAlex94]

Apologies, must have missed this! https://github.com/MrAlex94/Waterfox/commit/6f3f83685bdd12ff1d356c31d23eba08a8be4ae8

[grahamperrin]

I had forgotten this, too! I've been working without the features for the past eleven months. Now re-enabled.
