Backporting

Timeline

• No Backport (preferred): patchset for the next major stable

(Optional) Justification

• Emergency security update: patchset fixes CVEs, 0-days, etc
• Censorship event: patchset enables censorship circumvention
• Critical bug-fix: patchset fixes a bug in core-functionality
• Consistency: patchset which would make development easier if it were in both the alpha and release branches; developer tools, build system changes, etc
• Sponsor required: patchset required for sponsor
• Other: please explain

Change Description

Data source for the json file: https://firefox.settings.services.mozilla.com/v1/buckets/main/collections/query-stripping/records

Additional parameters can be defined with privacy.query_stripping.strip_list.

This does not fetch remote data on 12.5 and updating the JSON dump updates the local database.

There is an additional preference on 115 to strip query parameters when copying/sharing links from content or urlbar: privacy.query_stripping.strip_on_share.enabled
