This page is completely unusable due to lag. From the other comments it seems this is FF specific. One would think FB would have the resources to test new pages at least on common browsers before publishing.

Edit: The fix came quickly though.



Thanks, we're looking into how to fix the perf in FF. Meanwhile, it works on my tiny mobile cell phone.


Disabling the box shadow on .content-root fixes the performance bug (FF46.0).


Thanks for finding that out. We (Firefox) fixed a box shadow performance bug [1] in Firefox 47, which will be released on June 7th. It looks like this site is hitting that perf bug.

We just discovered the same by disabling the media query which handles the shadow. Thank you very much for investigating.


Seems to work fine on FF (46) now, thanks.


I can confirm the same laggy behavior in FF 46. But, strangely, it works completely fine on FF 48 (dev edition) :S


Cheng Lou fixed the firefox issue. Refresh and it should be fixed. Thanks again for reporting.


Completed nuked FF for me and for what its worth it doesn't even load in Edge. Just throws up a "This page is having a problem loading" page. Works fine in IE 11...


Edit: the page now works in FF.


Fixed. Seems to be a box-shadow issue on FF. Sorry for the trouble...


yea, open page, lag, close page. kthxbye


yea, open page, lag, see that it is facebook's usual bloat, task manager, kill firefox.exe process.


While not cool, that's a pleasant surprise to see something made-first for FF! Glad to see people still fighting against browser mono-culture.

The bug is only in FF, not the page only works in FF.


The lag is firefox specific, he means.


nonetheless it's nice to see something made for FF-only
