-Update *Thunderbird* to [128.10.1](https://www.thunderbird.net/en-US/thunderbird/128.10.1esr/releasenotes/).
Remove the *Tor Browser* and *Tor Browser (persistent)* folders: they are not necessary anymore, thanks to the more flexible confinement of *Tor Browser* we introduced in [[Tails 6.14.1|news/version_6.14.1]]. ([[!tails_ticket 15028]])
