Beta 105 big problems with FF 35

[GoogleCodeExporter]

I updated to Beta 105 on FF 35.  Problems include that the group tabs have all 
lost their background colors (all now gray).  And it takes several minutes to a 
group to load its tabs, when the group tab is clicked on.  Previously, the tabs 
loaded much faster.

What version of TabGroups Manager are you using?  beta 105
What Operative System are you using? 32 or 64 bits?  Windows home premiium 64 
bit
What version of Firefox are you using?  35

Never seen this. Disable all other addons and check result. 
Enable the addons step by step to find the culprit.
