Update *TorBrowser* to [14.5.2](https://blog.torproject.org/new-release-tor-browser-1452), which fixes [Mozilla Foundation Security Advisory 2025-37](https://www.mozilla.org/en-US/security/advisories/mfsa2025-37/).These vulnerabilities allow an attacker to perform an out-of-bounds read or write on a JavaScript object, but [don't allow breaking out of the Firefox sandbox](https://blog.mozilla.org/security/2025/05/17/firefox-security-response-to-pwn2own-2025/).
Remove the *TorBrowser* and *TorBrowser (persistent)* folders: they are not necessary anymore, thanks to the more flexible confinement of *TorBrowser* we introduced in [[Tails 6.14.1|news/version_6.14.1]]. ([[!tails_ticket 15028]])
