I'm looking into it...

[muffinresearch]

It's a regression from https://github.com/mozilla/addons-frontend/commit/0a0e650b25deb74841802e387f93920eda02135d - reverting that commit restores expected functionality.

This won't revert cleanly on master but a revert on the tag will work if we need to just get things working as quickly as possible and take more time with the patch for master.

@kumar303 also let me know if you need any help with reproducing this locally.

[muffinresearch]

Actually I'm going to go ahead and revert in the tag to unblock QA sooner.

Reverted for the tag see https://github.com/mozilla/addons-frontend/compare/2017.06.01...2017.06.08-2

@ValentinaPC this will mean it should be fixed on stage (once deployed shortly) but won't be fixed on -dev. Leaving this bug open to track the fix that needs to land in master.

Shoot, sorry I didn't notice this myself.

Verified this on stage while using FF53(Android 7.1.2). The install button is enabled (verified also for Nightly) Video:

Depends on mozilla/addons#10459
