blocklist.addonBlockChange#addonBlockChange | event | release | from 90 | An add-on is blocked, or an installed add-on is unblocked. When an add-on install/update is blocked, its installation is aborted and the add-on is no longer listed in the activeAddons field of TelemetryEnvironment. The value is the ID of the add-on. The object represents the reason for triggering the blocklistState check: "addon_install" is when an add-on is installed. "addon_update" is when an add-on is updated after an update check. "addon_update_check" is when an add-on is blocked during the update check. "addon_db_modified" is when an add-on's blocklistState was altered between application restarts. "blocklist_update" is when an add-on's blocklistState changed due to a blocklist update. This may be due to the blocklist being disabled by preferences or enterprise policies, but it is more commonly the result of updating entries in the blocklist.
|
blocklist.lastModified_rs_addons | scalar | release | 70 to 131 | Keep track of the last time the "addons" remotesetting blocklist has been successfully updated (as a datetime string in UTC format), set to "Missing Date" when the timestamp couldn't be retrieved.

|
blocklist.mlbf_softblocks_generation_time | scalar | release | from 133 | Keep track of the generation time of the addon blocklist's soft-blocks bloom filter. This marks the point in time until which signed add-ons are recognized by the selected bloom filter from the addons-bloomfilters collection. The value is a datetime string in UTC format, or "Missing Date" when unavailable.
|
blocklist.mlbf_softblocks_source | scalar | release | from 133 | The source of the RemoteSettings attachment that holds the soft-blocks bloom filter. Possible values are "dump_match", "cache_match", "remote_match", "dump_fallback", "cache_fallback", "unknown". "dump_match", "cache_match" and "remote_match" are expected known-good values, and means that the loaded bloomfilter matches the blocklist record in the RemoteSettings collection. The prefix denotes the immediate source of the loaded data: "dump" means packaged with the application, "remote" means a freshly downloaded bloomfilter, "cache" means a previously downloaded bloomfilter. "dump_fallback" and "cache_fallback" means that the last known bloomfilter was used, despite it not matching the latest record in the RemoteSettings collection. In this case the outdated bloomfilter is used as a fallback (e.g. because the latest version cannot be downloaded). "unknown" means that the bloomfilter cannot be loaded at all. This can happen if the blocklist is disabled via preferences or enterprise policies.
|
blocklist.mlbf_source | scalar | release | from 90 | The source of the RemoteSettings attachment that holds the hard-blocks bloom filter. Possible values are "dump_match", "cache_match", "remote_match", "dump_fallback", "cache_fallback", "unknown". "dump_match", "cache_match" and "remote_match" are expected known-good values, and means that the loaded bloomfilter matches the blocklist record in the RemoteSettings collection. The prefix denotes the immediate source of the loaded data: "dump" means packaged with the application, "remote" means a freshly downloaded bloomfilter, "cache" means a previously downloaded bloomfilter. "dump_fallback" and "cache_fallback" means that the last known bloomfilter was used, despite it not matching the latest record in the RemoteSettings collection. In this case the outdated bloomfilter is used as a fallback (e.g. because the latest version cannot be downloaded). "unknown" means that the bloomfilter cannot be loaded at all. This can happen if the blocklist is disabled via preferences or enterprise policies.

|
blocklist.mlbf_stashes | scalar | release | 78 to 91 | Keep track of whether the bloomfilter-based blocklist engine uses stashes from the addons-bloomfilters collection, together with an infrequently updated base bloomfilter. If false, the latest (full) bloom filter is downloaded on every update of the addon blocklist. This metric is only meaningful if mlbf_enabled is true.
|
blocklist.useXML | scalar | release | 70 to 75 | Keep track of the currently enabled blocklist engine (set to false if the remote settings blocklist is the one enabled).

A true value is also recorded here, and a false value is recorded to BROWSER_SET_DEFAULT_ERROR, if a user clicked 'Use Firefox as my default browser' on an in-product prompt. (Note that on Windows 8+ the latter action opens the right settings dialog but does not actually change the default browser without further user action.) On Windows, 'system default browser' is operationalized as whether Firefox is the default HTTP protocol handler. |
