This happens since the update of skia to milestone 113, bug 1821512.
Building to the consecutive changesets in mozilla-unified:
changeset: 736747:1e648bd9608a - builds and runs ok, no crash
changeset: 736753:a2c51a4dd225 [Update Skia source files to milestone 113]
[parent: 736747:1e648bd9608a]
build fails, needs 3427275d765c
changeset: 736754:3427275d765c [Update Skia build scripts]
build fails, needs d8c58792b823
changeset: 736755:d8c58792b823 [Fix Skia usage for API changes]
The build fails with an error similar to bug 1827727. With a backport of changeset 737070:93321213539f [Fix building Skia on GCC ARM] the build is successful.
Then runs ok, but about:preferences crashes
A new tab will open when accessed from about:about, but will crash when the tab is selected.

Can you please submit any relevant crash reports, as otherwise we don't have a way to debug what is going on here? Our own test builds on ARMv7 work fine under Clang.
It's possible this is a manifestation of bug 1838323? Try making sure you do not have --enable-lto as a build option, as that bug indicates this may be a bug in GCC's LTO. Also, try building with Clang and see if that helps. If this is bug 1838323, those would be the only workarounds I know of.
