This started with the last 2 or 3 releases of FF.  All I get is a blank page.  If I close that blank tab or hit the HOME button Speed Dial starts up with no problem.  I've checked and I do still have SD set up start up automatically.  I've also tried changing the setting to link to a SD bookmark I set up as the home page, but that didn't work either.  I switched to Quick Dial for a time and it did the same thing.  The developer of that add-on eventually found a bug that was keeping his program from starting up automatically and was able to correct it.  But I much prefer Speed Dial to Quick Dial.

Last week I started noticing my Firefox acting sluggish - taking 2x - 4x as long to load pages. I use EverSync in both Firefox and Chrome, and I don't see the slowdown in Chrome. I eliminated all my add-ons in FF, and narrowed down the poor behavior to EverSync. I use the browser a lot for intranet addresses, but I'm unsure if the slowdown is isolated to those addresses or if it is across any internet sites.

It's reported several times before, but still hasn't  fixed yet.
