but the version i am using is 87.0 so higher than 80 and i am using Firefox Linux on a chrome os.
At the bottom of the Import article, it mentions a preference you need to switch to enable the Import item on the menu.
However, I’m not sure the Chrome file has the correct layout – unless you created it by hand. You could take a look at the more general import feature and see whether it works (uncheck the categories you don’t want):

It should support Chrome format. If there are any issues, please report a bug and post it here.
