arkenfox/user.js 140.1

arkenfox user.js v140-1

on GitHub

The .1 refers to arkenfox, and has nothing to do with Firefox's versioning.

This is a point release for ESR users to match the upcoming change in arkenfox moving forward. It changes the arkenfox defaults for sanitizing history and downloads history on close to false. We enable sanitizeOnShutdown (2801) to help prevent 1st party website tracking across sessions. We consider history/downloads, which are not accessible to websites, as orthogonal and exempt these. This is a non-destructive change, i.e users won't lose anything. As always, those wishing differently can add overrides

The migration was to split history and downloads from formdata (caused by an earlier migration in FF128). The migration code was added for Firefox 136 and higher. ESR users would migrate when they updated to ESR140. In an abundance of caution, I changed them to match, but they should be obsolete - you should already be ESR140 or the latest Firefox, and a new ESR profile will migrate as you create the profile (i.e before you can add a user.js)
