[QUOTE="CyberTech, post: 806602, member: 67474"] Firefox users who have the content blocker uBlock Origin installed receive a permission prompt currently when uBlock Origin is updating. The prompt requests permission to store unlimited amounts of data. Firefox displays the prompt during the upgrade of uBlock Origin. The two options that are provided are to allow the permission by selecting "update" or to disallow it by selecting cancel. [IMG alt="ublock origin permissions"]https://www.ghacks.net/wp-content/uploads/2019/03/ublock-origin-permissions.png[/IMG] The prompt reads: The update won't be installed if you select cancel. The [URL='https://github.com/gorhill/uBlock/releases']change[/URL] brings the uBlock Origin extension for Firefox in line with the Chrome extension. Chromium-based versions of uBlock Origin requested the permission since 2014 when the extension was first published. Mozilla notes that extensions should only request the unlimited storage permission of they use more than 5 Megabytes of storage; this is the case for uBlock Origin as it uses more than 5 Megabytes of local storage in its default configuration. The change has no impact on the functionality of the extension at this point. Firefox does not enforce local storage quotas which means that extensions may store more than 5 Megabytes of storage even if they don't request the permission currently. It is possible that the storage limit will be enforced eventually, however. The new permission request in uBlock Origin is a preemptive one to avoid issues in the future if the limit is enforced by Mozilla. While preemptive in nature, it is still justified as the extension uses more than 5 Megabytes of local storage in its base configuration.
