Created attachment 8898648 [details] Screen Shot 2017-08-18 at 12.27.51 PM.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0 Build ID: 20170814073321 Steps to reproduce: my firefox had auto updated to version 55.0.2. i even downloaded latest version(55.0.2) again and installed.(note: i didn't uninstall the existing installation in the fear of loosing my tab data) Actual results: tab bar is half hidden Expected results: tab bar shouldn't be half hidden
I was able to fix the bug by disabling tab group plugin(https://addons.mozilla.org/en-US/firefox/addon/tab-groups-panorama/?src=search).
Summary: tab bar half hidden after update 55 → tab bar half hidden after update 55 with Tab Groups
this looks related https://github.com/Quicksaver/Tab-Groups/issues/541
The regression can be avoided via the preferences for Tab Groups. Specifically, disable the option to "Show the name of the active group". When this is turned off, the tab bar doesn't reduce its height. via: https://github.com/Quicksaver/Tab-Groups/issues/541#issuecomment-327040308 Seems like something the tab bar could prevent.
This add-on is not compatible with Firefox 57. Please contact the add-on author if you'd like support: https://github.com/Quicksaver/Tab-Groups/issues
