I was unable to reproduce this issue. 

Could you please try with a clean profile: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles ?

Also, you can try this by running in Safe mode: http://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .

Unable to reproduce it, WFM without any lines on any sites. Check out the options (like scaling) and compare different sites.

After some testing and disabling each add-on, I figured out that this issue is being caused by the add-on "Hide Tab Bar With One Tab 1.3".

It works fine in safe mode. But without safe mode, the issue still exists in the second tab after disabling all add-ons too. May be I need to create a new profile now.
