[OSpoon]

@cezaraugusto，Sorry, it seems that importing css does not work in development mode at the moment, We still need to make a few changes.

• invalid template：newtab

@OSpoon can't repro in the main branch. still happening?

Maybe due to caching, I will close this issue first.

Need to make sure again !!!

Steps

1. switch to the main branch；
2. create the newtab project: yarn extension create ../react-ext --template=react

Now ❓

1. Import file case error？
   

2. The development mode is missing？

Run yarn dev:

Run yarn start:
