[FIX] web: adapt JS boot logs to new Firefox version
[FIX] web: adapt JS boot logs to new Firefox version

When logging multiple elements in one log call in the new Firefox
version, all the elements are kept on one line. So if the second
element starts with a line feed, it will not go under the first
element but still be at the right of the first element, on a new
line.
