Comment on attachment 8651323 [details] pull request Hi Zibi Patch looks good and has my r+ . Its verified for gallery and video changes. A nit noted in github on comment. I observed in video app similar as noted in gallery group headers missing support for 'run time mirrored' pseudo locale (https://bugzilla.mozilla.org/show_bug.cgi?id=1170973#c7) Also, did you happen to check video app launch performance with the patch. For some reason I can't see raptor results on tree herder. Thanks for the patch!
