I have been using Small Tabs on Firefox for a long time and love it. But since either Firefox 39 or 40 I have noticed that scrolling has become very Jerky. I have spent quite a lot of time determining that Small Tabs is causing it. For the last few days I have been switching Small Tabs on and off so I am sure it is the problem. I am using a MBP running up to date Yosemite. I am seeing the jerky scrolling in all tabs … these include Twitter, Facebook and general web site scrolling…
Is anyone else seeing this please…
