Hi!

We had two Tor Browser releases this month, Tor Browser 7.5.4[1] and 8.0a7[2] picking up Firefox 52.8.0esr which contained a couple of security bug fixes. Apart from that we were able to fully concentrate on the Tor Browser transition to Firefox 60 ESR and on our Tor Browser for Android work.

Since May 30 we have Linux nightly builds available which are based on Firefox 60 ESR[3] and we meanwhile finished the transition for macOS as well[4]. That does not only include updating the toolchains to new Firefox requirements but getting our own extensions, Torbutton[5] and Tor Launcher[6], to work the new browser version, too.

We worked as well on the network code and new feature audit to make sure we don't miss criticial changes for Tor Browser and patch them if necessary.

On the mobile side we were fighting with an unexpected crash bug due to a Firefox patch closing a serious vulnerability.[7] We hope to have this problem resolved soon. Moreover, we made progress on having a first branch based on Firefox 61 ready[8], which will be the base for our first Tor Browser for Android alpha release.

The full list of tickets closed by the Tor Browser team in May is accessible using the `TorBrowserTeam201805` keyword in our bug tracker.[9]

For June we need to get outstanding build issues for the new Tor Browser for Windows resolved.[10] In parallel work to stabilize the code to be ready for the first alpha based on Firefox 60 ESR is under way, adapted to the new Firefox Photon user interface. If we get all the remaining pieces done in time the first ESR 60-based alpha will be out at the end of this month.

For mobile we should have first test builds ready this months and close remaining proxy bypass bugs, if there are any. Additionally, we are working together with the UX team to get the UI adapted to match what we'll ship for desktop.

All tickets on our radar for this month can be seen with the `TorBrowserTeam201806` keyword in our bug tracker.[11]
