When I have about 8 tabs open and I close one, the other tabs take a few seconds before changing size.

Reproducible: Sometimes

Steps to Reproduce:
1. Open about 8/9 tabs,
2. Close 1 tab,

The other tabs change size after only a few seconds.

The change in size of the tabs should be fluid.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

Hi,
The problem persists with Firefox in Safe-Mode and with a new profile.

Correct me if I am wrong - the other tabs start to change size only after you take the mouse out of the tab-strip area? (Tab closed using mouse)

@George Carstoiu : Yes, it's right. Is it purpose ?

Yes, that is the intended behavior of the browser that can explained thusly: if there are more tabs opened and a user wants to close several using the mouse and the X close button on each tab, if the tabs grow in size then the position of the X also changes, so the user has to continue changing the position of the mouse. If the tabs remain with the same size, X stays in the same place and thusly the user can close several at the same time without even changing the position of the mouse.

Basically, it is an ergonomics thing :)

Hope that I managed to get myself understood. Can you please change the status of the bug considering that this is the intended behavior of the browser? Thanks!
