That has not worked for everyone. It did not work for me and I read in the other thread I made reference too that there were a couple other people that adding classic theme restorer did not work for. What I wrote in reply 4 was the only thing that did work. The strange thing was when I went into the customization settings the title bar box was checked. I unchecked it, restarted Firefox and rechecked the box and it was then my buttons returned and the title bar returned to normal. I do have classic theme restorer enabled now but at the time I made the changes that worked it was not enabled.
Well maybe you were in a particular setting in your Firefox settings
Before installing CTR, once have usually to verify/modify some appearrences settings in Firefox itself, and after CTR is correctly installed as add-on, you have to search a little in all the differrents settings of it to get Firefox the way you want.
here's how is mine with latest Firefox version :
i think bebi bulma should be in a differrent case as you, because it's an upgrade of Firefox 28 to Firefox 40 and appearrance is all changed because of "Australis theme" now used. CTR is mainly done do get Firefox with the "old default theme", but BTW it brings some settings which are allowing Firefox to be better skinned with WindowBlinds that it was without these settings
