on mac i see l120n.min.js blocked; the safebrowsing page shows up but not the text. it works if i reload the safebrowsing page.

^ that was on latest master. on 15.304 i get the same thing as @luixxiul

[alexwykoff]

This appears to have regressed in 308

STR:

1. With a clean profile go to http://alexwykoff.com/tests/testlinks.html
2. Use cmd + click to open the http://downloadme.org/ link in another tab

Expected result : about:safebrowsing is displayed appropriately

Actual result : a blank page is displayed

Works fine on Windows on a clean profile when opening with Ctrl+Click from http://alexwykoff.com/tests/testlinks.html

@alexwykoff i think it's actually a separate issue, not a regression. the original issue was for links entered directly, not via cmd-click

[alexwykoff]

Since other cmd-click pages are working, is it reasonable to believe it is related?

Clicks and cmd-clicks should be part of the test for this issue as well as simply entering downloadme.org into the urlbar.

i agree the functionality should be tested; however @luixxiul's original issue showed that about:safebrowsing loaded but without text (due to the l10n library being blocked). the cmd+click issue shows nothing loaded at all
