No
GNU GPL v2.0 or later is strong copyleft; combining it into a Mozilla Public License 2.0 project would force the combined work to be GNU GPL v2.0 or later (not Mozilla Public License 2.0). If your project must remain Mozilla Public License 2.0, avoid GNU GPL v2.0 or later code.
| License | Family | Patent grant |
|---|---|---|
| GNU GPL v2.0 or later (GPL-2.0-or-later) | strong-copyleft | No (implicit at most) |
| Mozilla Public License 2.0 (MPL-2.0) | weak-copyleft | Yes |
GNU GPL v2.0 or later: GPL-2.0 with explicit upgrade path; users may pick GPL-2.0 or any later GPL.
Mozilla Public License 2.0: File-level copyleft: modifications to MPL files must be MPL, but linking with non-MPL code is fine.
If you found this page because you're trying to figure out whether shipping a particular dependency is safe, the answer above is a starting point — not a substitute for reading the actual licenses or talking to a lawyer when stakes are high.
LicenseHound walks every transitive dependency in your repo, maps each to its SPDX license, and flags pairs like this one in PR comments. The CLI is free; the team dashboard is paid.
