Bug#860574: firefox-esr: At start Firefox opens up quite quickly but than it freezes for 15 seconds

[Carlo Marchiori]

Package: firefox-esr
Version: 52.0.2esr-1
Severity: normal

Dear Maintainer,

At start Firefox opens up quite quickly but than it freezes for 15 seconds.

During these 15 seconds the browser is totally unresponsive, trying to type in
the address bar or clicking on it doesn't move the focus or show the caret in
it. There is no sign of any ongoing work being done by the browser or any type
of visual feedback to the user about what's happening.
