Comment 3 robberphex 2017-05-31 07:44:27 UTC 
When Firefox UI is is freezed, Firefox used 100% of CPU.
Comment 4 Martin Stransky 2017-05-31 10:40:41 UTC 
That's a freeze in mozilla::storage::Connection::prepareStatement(), Firefox may access your profile and something went wrong. Can you please try to create a new fresh profile (by $firefox -ProfileManager) and check if it also hangs?
Comment 5 robberphex 2017-06-01 02:18:08 UTC 
After I created a new profile(and deleted old one),

Firefox still hangs occasionally.(it hangs during I edit this comment :( )
Comment 6 Martin Stransky 2017-06-01 08:58:26 UTC 
Thanks. Can you please test a binary downloaded directly from Mozilla.com? And/or please test flatpak nightly package from https://firefox-flatpak.mojefedora.cz/. The problem may be caused by system sqlite which is enabled on Fedora 26.
Comment 7 Paul DeStefano 2017-06-03 03:26:44 UTC 
I've been having this problem a lot since F26 upgrade, too.  I am now using FF53.0.3 binary from Mozilla I just downloaded.  Seems better already, but can't be sure yet.
Comment 8 robberphex 2017-06-04 05:31:50 UTC 
While using Firefox binary from mozilla.com, I haven't meet this bug again.
Comment 9 Martin Stransky 2017-06-09 09:42:49 UTC 
Let's switch to in-tree sqlite in next update - Firefox 54.
Comment 10 Paul DeStefano 2017-07-01 08:33:11 UTC 
So, I just had a hang using mozilla binary FF54.0.1.  So, that's concerning.
Comment 11 Paul DeStefano 2017-07-01 08:34:30 UTC 
Hmm, I can drag my window, though.
Comment 12 Martin Stransky 2017-07-12 07:27:44 UTC 
Okay, please reopen if you see such issue again.
Comment 13 robberphex 2017-09-13 02:16:25 UTC 
this bug appears again at firefox-55.0.3-1.fc26.x86_64,

so I open a new bug https://bugzilla.redhat.com/show_bug.cgi?id=1491084
