When I open a browser in terminal (I've tried Firefox and Google Chrome) I get error messages.

When I open Firefox it spits out this:

Performance warning: Async animation disabled because frame size (2280, 97) is bigger than the viewport (2160, 1188) or the visual rectangle (2280, 97) is larger than the max allowable value (17895698) [div]

(process:2659): GLib-CRITICAL **: g_path_get_basename: assertion 'file_name != NULL' failed
Vector smash protection is enabled.

(process:3433): GLib-CRITICAL **: g_path_get_basename: assertion 'file_name != NULL' failed

(process:3509): GLib-CRITICAL **: g_path_get_basename: assertion 'file_name != NULL' failed

###!!! [Child][MessageChannel] Error: (msgtype=0x80000F,name=PHttpChannel::Msg___delete__) Channel closing: too late to send/recv, messages will be lost

And when I open chrome it spits out this one:

[WARNING:flash/platform/pepper/pep_module.cpp(63)] SANDBOXED
Vector smash protection is enabled.

After looking into both of these (and doing some experimentation) I couldn't find a solution, but it seems that this is a problem with flash and not html5. Also, this happens when I open firefox in safemode.

This hasn't caused me any (noticeable) problems yet, but it irks me that it is happening and I have no clue what's going on. To the best of my knowledge this problem wasn't happening last night when I last got online.

Lastly I am running 64 bit Ubuntu 16.04 if that helps.

If your browsers run as expected then the messages can safely be ignored. Generally they are intended for developers, not for end users, and provide information for debugging.

Sandboxing is a security feature. Chrome is restricting the actions of code from the site, for example not allowing it permission to read files on your computer.
