就是修正弄得全世界大爆炸的那个bug。
我就贴尚未解决的问题:
A small number of add-ons may be listed as unsupported or may not appear
in about:addons. Their data is not lost; users should be able to re-install
the add-ons and recover the data (Bug 1549129).
If add-ons that use Containers functionality (such as Multi-Account
Containers and Facebook Container) were disabled as part of this problem, any
lost site data or custom configurations for those add-ons will not be
recovered by this release. Users may need to set them up and login again in
about:addons (Bug 1549204).
Themes may not be re-enabled. Users may need to re-enable them in
about:addons (Bug 1549022).
Home page or search settings customized by an add-on may be reset to
defaults. Users may need to customize them again in about:preferences or
about:addons (Bug 1549192).
