My reading of these licenses is that they are both so-called
"weak copyleft" licenses. "Copyleft" meaning that derivatives of LGPL
code must be published under LGPL or MPL, respectively, and no
relicensing is allowed. Therefore, it is not OK to
cut-and-paste LGPL code into an MPL file, or vice versa. "Weak,"
in that their copylefts stop at file boundaries, so it is OK to link an
with an MPL file.
By the way, if the MPL code you are referring to is perhaps Mozilla
Firefox, then it is already triple-licensed MPL/GPL/LGPL, and you may
use it with LGPL-only code with no restrictions by electing to
the result as LGPL.
IANAL, TINLA, etc.
