Thunderbird’s Bug Bash: Tackling Security Flaws with a Digital Flyswatter! 🚫🔨
Thunderbird 140.1 just revamped its security with bug fixes that even Inspector Gadget would appreciate. From fixing nameless cookies to ensuring search terms don’t linger like unwanted guests, these updates promise to keep your emails safer than a squirrel with a nut in a locked vault.

Hot Take:
Thunderbird’s latest update is like finally getting that long-overdue oil change. Sure, you’re glad it’s done, but why do cars (and email clients) have to be so high maintenance? This time, Mozilla has patched Thunderbird 140.1 with fixes for vulnerabilities that sound like they were cooked up in a sci-fi lab. From JavaScript engine quirks to cookie shenanigans, this update is a rollercoaster of tech jargon. Grab your decoder ring, folks, because this ride is going to be as wild as trying to fold a fitted sheet!
Key Points:
- Thunderbird 140.1 patches multiple high-impact vulnerabilities, including JavaScript engine flaws and DNS rebinding.
- The security update addresses issues like nameless cookies overshadowing secure ones and potential code execution via “Copy as cURL”.
- Scripting is disabled in Thunderbird for reading emails, so these exploits are more of a risk in browser-like contexts.
- Moderate vulnerabilities include incorrect URL stripping in CSP reports and CSP bypass by XSLT documents.
- Low-impact issues range from search terms lingering in the URL bar to incorrect JavaScript state machine handling.
