Tor Browser 6.0.2 is a fixup release to address the most pressing issues we found after switching to Firefox 45.2.0esr.
In particular, we resolved a possible crash bug visible e.g. on Faceboook or mega.nz and we fixed the broken PDF download button in the PDF reader.
Note: In version 6.0 we started code signing the OS X bundle for Gatekeeper support. A side effect of this signature is that it makes it harder to compare the bundles we ship with the bundles produced using reproducible builds, therefore we plan to post instructions for removing the OS X code signing parts on our website soon. An other effect is that the incremental update will not be working for users who installed the previous version using the .dmg file, due to bug 19410. The internal updater should still work, though, doing a complete update.
Update (June 23, 12:38 UTC): We have still some users that report crashes on Facebook and mega.nz. We suspect this happens because those users are not using Tor Browser in its default configuration but have left the Private Browsing Mode. There are at least two workarounds for this: 1) Using a clean new Tor Browser 6.0.2 (including a new profile) solves the problem. 2) As files cached by those websites in the Tor Browser profile are causing the crashes, deleting them helps as well. See bug 19400 for more details in this regard.
Here is the full changelog since 6.0.1:
- All Platforms
- Bug 19348: Adapt to more than one build target on Windows (fixes updates)
- Bug 19276: Disable Xrender due to possible performance regressions
