Hi all,  
I just uploaded my first add-on for approval. It went through, but when I try to install it from its page error will show up that this addon is not compatible with Firefox 57.0.2 . When I load it locally through about:debugging it loads without problem.

In manifest.json in “applications” I only have parameter “strict\_min\_version”: “42.0” , no max version.

Add-on: [https://addons.mozilla.org/en-US/firefox/addon/crypto-prices-binance/](https://addons.mozilla.org/en-US/firefox/addon/crypto-prices-binance/)

Thanks for help

UPDATE: Fixed, max version line wasnt removed in manifest.json
