Re: [tor-talk] Tor Browser crash


I attached a screen recording showing Tor Browser crash.

Strangely enough, I couldn't reproduce the crash in a virtual machine with Ubuntu 16.04 64-bit installed. I doubt the crash has something to do with screen resolution and the "Scale for menu and title bars" feature of Unity. (?)

My display settings: Ubuntu 16.04 64-bit with Unity desktop environment. On a computer with HiDPI screen. Change the screen resolution to 3840x2160 (4k) resolution. Change "Scale for menu and title bars" to 2.5x

0:02 I selected a new circuit for that site.
0:05 I clicked on the NoScript (S) icon and wait for page to reload. I did not click on any NoScript menu item at that moment.
0:07 - 0:11 Still waiting for page to reload and waiting for the "Blocked object" menu item to appear. I did not click on any NoScript menu item at that moment.
0:17 My cursor was on the "Blocked object" menu item. I started repeatedly clicking on this menu item.
0:19 I clicked on the NoScript icon (S) to make the drop down menu disappear. I clicked on it again immediately to make the menu reappear.
0:20 I moved my cursor onto the "Blocked object" menu item. This time, Tor browser window was gone after I clicked on the "Blocked object" menu item only once.

> TBB version
6.5.1 (based on Mozilla Firefox 45.8.0)

> OS / version
Ubuntu 16.04 LTS (64-bit), default Unity desktop environment

> addons / plugins
The default ones.
Extensions: HTTPS Everywhere, NoScript, TorButton, TorLauncher.
Plugins: None
Services: None

> What was blocked
Downloadable fonts were blocked in "High" security level mode.

> Why do you repeatedly click on them
When I had to temporarily allow scripts for that page, I clicked on the NoScript (S) icon and immediately selected the first menu item, but that page contains downloadable fonts, so the first menu item does not say "Temporarily allow all this page" but says "Blocked objects." So by mistake I clicked on the "Block objects" menu item. Tor Browser then crashed.

Later when I wanted to reproduce the crash, I had to click on the menu item said "Blocked objects" many times in order to make Tor Browser crash.
