Версия 0.18.1
Выпущено 28 июня 2024 г. - 441,59 КБРаботает с firefox 79.0 и выше, android 120.0 и вышеFix the scope where updateCount used by FPD is created (Pagure issue 141. Although the function was not visible to page scripts, page script could have define their own function with several consequences as JShelter would call the page script function:
FPD would not learn about the calls and consequently would not detect fingeprinting attempts by the page,
pop up would not show calls to the wrapped APIs,
the page would be able to detect that JShelter is being installed,
if the page would not expect that someone is calling its function it can have any undesired consequences.
The bug was present in JShelter since the introduction of FPD in 0.6 and all versions up to 0.18 are affected.Исходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0

Версия 0.17
Выпущено 3 нояб. 2023 г. - 447,3 КБРаботает с firefox 78.0a1 и выше, android 120.0 и выше* Added support for built-in tweaks for specific domains. The goal is to list several domains that
break unnecessarily. Typically, an addition to the list should be well explained and must not
lower protection. A nice candidate is WebWorker and the protection of Strict (break) and Remove.
* Updated translations
* Improved FPD report based on user feedback:
* Do not refresh report automatically when tracking callers but introduce an update button so that
users refresh when convenient (prevent glitches in the interfaces)
* Add buttons to hide/show details and fold/unfold groups
* Do not show traces in bold to better differentiate between API names and traces.
* Add possibility to forget current traces. Useful when there is a fingerprinting script that activates after some action. The button allows the user to hide the traces triggered in the past and later load only new traces.
* Add support for signing for Android on AMO: https://blog.mozilla.org/addons/2023/10/05/changes-to-android-extension-signing/, so we needed to increase minimal supported versionИсходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0
Версия 0.16
Выпущено 27 сент. 2023 г. - 427,93 КБРаботает с firefox 68.0 и выше* Remove Workers in Recommended JSS level to make JShelter compatible with some pages. This change might be reverted when [Pagure issue 80](https://pagure.io/JShelter/webextension/issue/80#comment-852202) is solved.
* FPD: Add possibility to learn the calling stack of functions that lead to the tracked APIs ([Pagure issue 52](https://pagure.io/JShelter/webextension/issue/52)). This information can be used to create block list or to study the calling code and its effects.
* FPD: Fix browser overloading by FPD messages by HTMLElement.prototype.offsetHeight and offsetWidth wrappers that might have crashed browsers.
* FPD: code cleanupИсходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0
Версия 0.15.2
Выпущено 21 сент. 2023 г. - 425,35 КБРаботает с firefox 68.0 и выше* Fix window.name protection, do not clear the property in the first visited page see https://pagure.io/JShelter/webextension/issue/116#comment-875070 for more details. The fix affects all Chromium-based browsers and Firefox installs with the protection active (by default it is off in Firefox as Firefox contains the protection since Firefox 88). This fixes, for example, reCaptcha.

Версия 0.12.2
Выпущено 7 июня 2023 г. - 367,6 КБРаботает с firefox 68.0 и выше* Reimplement AudioBuffer.prototype.copyFromChannel to prevent multiple farbling of the same data
* Optimize performance of Canvas and Audio wrappers
* NSCL updated: JShelter benefits from the mechanism to prevent inconsistencies / breakages when the extension gets updated and therefore the old wrappers are invalidated by Firefox which nukes their sandbox and new ones are installed on extension's automatic restartИсходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0
Версия 0.12.1
Выпущено 19 апр. 2023 г. - 367,32 КБРаботает с firefox 68.0 и выше* bugfix: Return the correctly created Worker object from the `Strict` wrapper.Исходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0
Версия 0.12
Выпущено 19 апр. 2023 г. - 367,32 КБРаботает с firefox 68.0 и выше* Cope with the changes of reported plugins and supported MIME types in the HTML standard and
browsers: The purpose of the wrappers is solely to prevent fingerprinting. As browsers return the
same 5 plugins, browsers modyfing the array stand out, which makes them more fingerprintable.
Hence, JShelter does not modify the empty list or the list of five standard plugins.
Reconsider and rewrite Web Worker wrappers (pagure issue 80)
* `Strict` WebWorker policy intentionally breakes Web Workers
* New policy to `Remove` Web Workers used for `Turn fingerprinting protection off` and `Strict` level.
* `Medium` WebWorker policy renamed to `Low` as it only tackles a single issue with Workers.
See FAQ for more information on current Worker wrappers.
Note that the `Low` policy does not work as intended in Firefox and will be fixed in future.
However, it was broken in the same way before 0.12 and the other changes are worth distributing
among our users.Исходный код выпущен на условиях Только Стандартная общественная лицензия GNU v3.0

Версия 0.11.3
Выпущено 28 мар. 2023 г. - 369,15 КБРаботает с firefox 68.0 и выше* bugfix: Remove race condition that reset default level to Recommended from custom levels. Unfortunately, affected users need to manually restore the default level as JShelter cannot distinguish affected users automatically.
* bugfix: Deactivate NBS in the presence of HTTP proxy in Firefox, see pagure issues #41 and #85 for more details.

* Do not change values depending on activated tweaks
* Remove obvious reversibility of the canvas farbling
* Unify wrapping between H-C and WEBGL
* Unify the wrappers in Strict and Farbling wrapping of WebGL parameters (some were farbled but not disabled on Strict)

number (that might have been revealed after several visits)

randomString()
* Strict: Return empty UNMASKED VENDOR and RENDERER - Previosuly, these values depended
on the domainHash, that meant that the unique value could be used to uniquely fingerprint the device.
* Harden WEBA farbling
* Scramble the output of PRNG with domainHash to prevent guessing the
future PRNs
* Try to improve speed as possible but the wrapping is likely slower
than 0.7.x

* Fix Pagure #18 Optional permissions for AFPD - it is not necessary to give browsingData
* Allowlist options in NBS and FPD changed breaking backwards compatibility
