Tabs missing + solution Rated 4 out of 5 stars

I use Tree Style Tabs in Ubuntu 9.10(also a problem in 9.04). When I close down firefox and load it up again, loads of my tabs are missing, although they are still loading in the background. I have around 90 tabs open.

sorry for the caps, thought it was best as this solution is better than ScienceBrain's.
My tab bar is vertical.
1. click on the "open a new tab" button and drag it. Drag the bar to the bottom middle of the browser and then the bar becomes horizontal.
2. When it is horizontal, you click and hold down on the left scroll button to let it take you all the way back to the first tab.
3. When you are at the first tab, drag the bar to the middle right/left of the browser. Then you can see all your tabs again.

This fixes the problem for that session. Restarting Firefox might mess up your tabs again. I hope to see a solid solution soon.
