Changes
- Added a separate toggle in settings to enable/disable JIT for extensions when JIT is otherwise disabled globally *(Disabled by default)*, located at
Settings->IronFox->IronFox settings->Security->Enable JavaScript Just-in-time Compilation (JIT) for extensions.
- Added support for natively enabling/disabling WebGL per-site via FPP overrides. It is now recommended to disable the uBlock Origin
Block WebGLlists (TheBlock WebGLlists will be removed from the uBlock Origin config entirely in the near future, but we're keeping them for now to ex. give users time to update). See Notes below for details, such as how you can manually allow desired websites to use WebGL.
- Added a toggle in settings to enable or disable our default WebGL overrides *(Enabled by default)*, located at
Settings->IronFox->IronFox settings->Privacy->Enable WebGL overrides from IronFox. When WebGL is enabled, this setting enables WebGL by default for certain websites, to reduce breakage/unexpected behavior. Note that this list is NOT fetched/updated remotely.
- Added a toggle in settings to enable or disable spoofing the timezone to
UTC-0*(Disabled by default)*, located atSettings->IronFox->IronFox settings->Privacy->Spoof timezone to UTC-0.
- Added a toggle in settings to enable or disable our default timezone overrides *(Enabled by default)*, located at
Settings->IronFox->IronFox settings->Privacy->Enable timezone spoofing overrides from IronFox. When timezone spoofing is enabled, this setting disables timezone spoofing by default for certain websites, to reduce breakage/unexpected behavior. Note that this list is NOT fetched/updated remotely.
- Added a toggle in settings to enable or disable Mozilla's default fingerprinting protection overrides to reduce website breakage *(Enabled by default)*, located at
Settings->IronFox->IronFox settings->Privacy->Enable fingerprinting protection overrides from Mozilla. Note that this list IS fetched/updated remotely.
- Added a toggle in settings to enable or disable our default fingerprinting protection overrides to reduce website breakage *(Enabled by default)*, located at
Settings->IronFox->IronFox settings->Privacy->Enable fingerprinting protection overrides from IronFox. This toggle does not disable fingerprinting protection overrides that we set to harden protection for certain websites. Note that this list is NOT fetched/updated remotely.
- Implemented Phoenix's extension blocklist to block malicious/phishing/sketchy extensions.
- Locked Gecko preferences controlled by UI settings (See details).
- Prevented the JIT toggle from controlling
javascript.options.main_process_disable_jit, as this pref is not required for JIT to function, and is preferable to leave on - even when JIT is enabled, to improve security.
- Updated to Firefox
144.0.
- Updated microG to
v0.3.10.250932.
- Updated Phoenix to
2025.10.12.1.
- Other minor tweaks, adjustments, and enhancements.
Notes
You can manually allow websites to use WebGL with the privacy.fingerprintingProtection.granularOverrides preference at about:config. For instance, if I want to allow example.com to use WebGL, I would set the value of privacy.fingerprintingProtection.granularOverrides to:
[{"firstPartyDomain":"example.com","overrides":"-DisableWebGL"}]
If I also wanted to allow example2.com, I'd set the value to:
[{"firstPartyDomain":"example.com","overrides":"-DisableWebGL"},{"firstPartyDomain":"example2.com","overrides":"-DisableWebGL"}]
Please report websites that require WebGL to us if possible, so that we can investigate and potentially add them to the default WebGL overrides list.
