Issues with opening multiple sites at a time in Pale Moon

I have issues with opening multiple sites at a time in the latest Pale Moon. They are as follows:

1. It has trouble opening multiple sites at a time by using "Open All in Tabs" in the context menu of a bookmark folder (they all get stuck loading).

2. Some of the opened tabs report that the server the page is hosted on cannot be found (a refresh gets the page to load).

A debug log made under revision 72996 is attached.
