LocalStorage is not cleared by add-on #246

Closed ontheair81 closed 4 years ago

ontheair81 commented 6 years ago

Hello,

I am using the add-on "Self-Destructing Cookies" for privacy reasons. This add-on deletes cookies and LocalStorage except of a whitelist.

The add-on is working fine in Firefox ESR, but not in Waterfox. LocalStorage is never cleared.

Waterfox 55.2.2 on Windows7 Pro Self-Destructing Cookies version 0.4.12

Thank you for any help!

criztovyl commented 6 years ago

I guess this could be related to e10s, but SDC shouln't allow e10s to be enabled. Could you screenshot about:support?

ontheair81 commented 6 years ago

Im not so sure what might be interesting in this case from about:support, so I am posting the whole content as text instead of a screenshot. Its in german, but should be no problem, I guess.

SDC can't handle Local Storage with e10s and you seem to have enabled it. But I thought that SDC, marked as e10s-incompatible by it's author, wouldn't let you enable e10s.

(A screenshot of about:support would have shown if you have e10s enabled without the rest you pasted here, the rest is uninteresting in this case.)

ontheair81 commented 6 years ago

Thank you for your help!

(Was not sure which part is interesting in this case, so I just posted all to be sure ;-) )

grahamperrin commented 6 years ago

@ontheair81 does Self-Destructing Cookies 0.4.12 have the required effect in Waterfox 56.0.3?

For extensions such as that, please disallow multi-process Waterfox before testing with 56.0.3. Thanks.

ontheair81 commented 6 years ago

I had some strange effects with that:

This was 3 months ago. As I needed a quick solution for this problem, I changed to FirefoxESR and later to Firefox Quantum (where the API now is active and some AddOns are able to clear LocalStorage now).

Unfortunately it was a busy time and I was not able to check it again with Waterfox - as I want to move from Quantum to Waterfox again.

But if other people have more current informations about this issue, would be nice to hear about!

grahamperrin commented 6 years ago

Self Destructing Cookies

After disabling e10s, SDC should work again with clearing LocalStorage. But it did not.

OK, I might take a look at that issue this weekend.

Other extensions that might be of interest

@WagnerGMD recently drew attention to Shim Storage.

I occasionally use legacy version 0.2.6 of Privacy Settings, which can affect dom.storage.enabled although I have no experience of using the extension in that way.

grahamperrin commented 6 years ago

https://addons.mozilla.org/addon/self-destructing-cookies/ states:

… incompatible with Firefox 55+ …

– and Waterfox 56.0 was based on Firefox 56.0.2, so I should not expect the extension to work reliably with any 56.x release of Waterfox.

GitCurious commented 5 years ago

Will Waterfox ever get the API that allows extensions to clear localstorage ?

… API that allows extensions to clear localstorage ?

Mozilla bug 1355576 - Implement clearing of LocalStorage in browsingData API (VERIFIED FIXED in Firefox -esr52)

For 1355576 three commits are found, but I don't know whether their changes are in master:

https://bugzilla.mozilla.org/show_bug.cgi?id=1355576#c47 (2017-11-07) refers to:

Still, I don't know whether that would help. Bear in mind, the explicit incompatibility with Firefox 55+.

@ontheair81 would you like to change the title of this issue? To include the phrase Self-Destructing Cookies

ilu33 commented 5 years ago

The present title is fitting. This is not only about self-destructing-cookies but a general problem. @grahamperrin Since you investigated this issue: Did you find ANY addon that clears local storage in waterfox 56? I can't find any.

grahamperrin commented 5 years ago

Maybe this?

Foundstone HTML5 Local Storage Explorer

Site Bleacher

I used Foundstone HTML5 Local Storage Explorer to capture information including a few lines that began "https://helpx.adobe.com:443/"(probably from Flash Player Help) then Site Bleacher to clean at Adobe's page. Then again Foundstone HTML5 Local Storage Explorer, which no longer found the lines.

Others

https://addons.mozilla.org/search/?q=local%20storage&type=extension&appver=56.2.6 finds 86 at the time of writing. Not all suitable for clearance of local storage with Waterfox 56.x, but there is (for example) Site Bleacher, first and foremost, which does seem to successfully clean local storage on a site-specific basis.

I wondered whether https://addons.mozilla.org/search/?q=local%20storage&type=extension&appver=56.0 or (no application version) https://addons.mozilla.org/search/?q=local%20storage&type=extension would yield a broader set of results but no, for both searches there are 86 results.

Clear Browsing Data and Fire Clear Cache are examples of extensions that can be installed without warning since Waterfox 56.2.3 but might be not entirely compatible with Waterfox 56.2.6. For each extension of interest, check its versions page; if there's a requirement for Firefox 57.0, don't assume complete compatibility with Waterfox 56.2.6.

ilu33 commented 5 years ago

Thanks you for your recommendations. Sadly HTML5 Local Storage Explorer is not open source.
Most of those 86 addons found by your search use local storage in some way instead of cleaning it. Others are not available for our browser version in spite of your search criteria (I cross tested on a FF 56, same result), notably ClearPrivateData, Clear Browsing Data and StoragErazor. Clear Cookies and Storage Button, Cookiebro (permission to Store unlimited amount of client-side data ??!), Nuke Private Data (permission to read and modify bookmarks??!), Browser Cleaner Pro (no function on firefox) and Website Information are not open source. But I found several test candidates: Site Bleacher, Cookie Quick Manager, eCleaner. I'll report back.

ilu33 commented 5 years ago

Cookie Quick Manager, Cookie Auto Delete, Site Bleacher, Remove Cookies and Storages Button and Remove Cookies Button can delete local storage of the open tab - sometimes but sometimes not. You have to open the exact subdomain which is not even possible on some domains. http domains persist because you are redirected to the https site. None of them auto-delete. None of them remove addons.mozilla.org entry. None of them remove indexdb data. These addons are of no help.

Deleting individual entries with HTML5 Local Storage Explorer (not open source) works well.

Clear Cookies and Storage Button (not open source) and ecleaner (Forget Button) both work - all local storage shown by HTML5 Local Storage Explorer is gone - extension data included which should not have happened according to settings. So I have at least a radical solution.

But everything under /waterfox/storage (indexdb data?) is still there. ecleaner has an old issue about it [https://github.com/andy-portmen/ecleaner/issues/15] but development seems dead anyway.

grahamperrin commented 5 years ago

… indexdb data? …

If you use any file manager in that area, take care – simply browsing the file system might inadvertently cause failure of IndexedDB. You can use Firefox Storage Test to tell whether things are good, working, operational.

ilu33 commented 5 years ago

Course I did :-) Thanks for the link, and yes, indexeddb is broken. What other choice do I have but break it? I don't want to live with youtube and other tracking (youtube places an ID into indexedDB). This is a serious problem for a privacy oriented browser like waterfox. A self-operating privacy addon like Self-Destructing Cookies - operating for every kind of client-side storage - is sorely missing. If I understand correctly the API is missing for everything but cookies, so probably nothing much @mralex can do about it - short of setting dom.indexedDB.enabled to false (as the ghacks user.js does).

ilu33 commented 5 years ago

Just fyi the proposals for indexeddb from the wilderssecurity forum:

  1. There is the Disable IndexedDB add-on. Unfortunately, exceptions for specific sites are not possible (so you have to manually allow IndexedDB for them). Furthermore, we don't know if it will still be available for Firefox 57+ as it isn't a webextension.
  2. In your Firefox profile is a folder called storage which in turn contains the three subfolders default, permanent and temporary. The permanent folder is obviously used by some add-ons and should probably not be touched. Now the trick is to delete everything which is in the default and temporary folders (you'll find most probably entries from various websites) and make those two folders read-only. Needless to say, that dom.indexedDB.enabled should be left set to true. ... It seems that those sites still think that IndexedDB is available although they cannot write to those folders mentioned above.
grahamperrin commented 5 years ago

IndexedDB discussions (off-topic from LocalStorage) might become sprawling. FYI:

LocalStorage is not cleared by add-on

Does Cookiebro not work?

ilu33 commented 5 years ago

I did not test CookieBro due to the excessive (so I thought) permissions and due to it not being open source. I settled on ecleaner. But I will reconsider this. And sorry for the off-topic - I took the topic not by word but by supposed intent as in: looking for something that clears all kind of storage. I wanted to share my findings but of course I could have opened my own topic.

GitCurious commented 5 years ago

CookieBro still does not work with Waterfox in respect to clearing the webappstore.sqlite file, which I can see does get cleaned when using Firefox

I guess this is until WF gains some kind of parity with Fx v57 ?

All this technical stuff confuses me, so I have been using Firefox instead since last year as I do use CookieBro for it`s cookie handling capabilities.

[I do keep checking if Cookiebro works properly when Waterfox is occasionally updated]

MrAlex94 commented 4 years ago

LocalStorage may be quite a difficult update - so I'd say if you're focused on extensions that do such things, possibly considering using Current now that it's available (wasn't at the time?).
