This script is a hack that provides delayed loading for content buffers.
|
||
|
|
The initial url of a buffer will not be loaded until that buffer is
|
||
|
|
switched to. Precaution is taken that the buffer's display_uri_string
|
||
|
|
returns the delayed url, not about:blank, so things like tabs and sessions
|
||
|
|
will still work properly.
