Hi everyone!
Firefox 67.0 has a breaking change that overrides any variable with name u2f
. This breaks many Vaadin and GWT applications because the minifier quite quickly starts using u2f
as a function or variable name. That’s why we’ve released the following maintenance versions of the platform:
- 6.2.10
- 6.3.8
- 6.4.7
- 6.5.10
- 6.6.8
- 6.7.15
- 6.8.18
- 6.9.10
- 6.10.10
- 7.0.7
All of them include fixes for Firefox 67.0+:
- Override reserved globals for Firefox 67 #2146.
In order to determine if your application is affected by the problem described above, you need to do the following:
- Open Developer Tools
- Go to the Sources tab
- Open
...WidgetSet-0.js
(it can have a different name) - Search for
u2f
(see the image below)
If u2f
is found then update your solutions as soon as possible!
Please note that U2f
and u2F
are correct names.
