I upgraded to Firefox 3.5.2 from Firefox 3.0 last week and it's been **** me off ever since!!

I've been using Firefox for a couple of years now and this has never happened!!

What is it doing, you ask?

1. Tab Browsing: I click on one of the many Tabs I have open on top to go from one website to another. LEFT CLICK, which is NORMAL.

Well sometime it works fine and sometime after I click on the tab and it's in the middle of switching from theTAB I am currently viewing to that TAB, what does it do?

It opens the TAB in a New Firefox Window!!

2. Scrolling within a website - I am looking at a webpage like Movie-List FORUM, reading a thread and scrolling down using the scroll wheel on my mouse. Well, I am scrolling down and BOOM, the page jumps and reopens into a New Firefox Window.

At first I thought maybe I push down on the scroll wheel by accident while Scrolling but I even tried scrolling real real slow with very little pressure on the scroll wheel but it still does it!!

3. Messing up while posting a thread, reply to a thread.

I have finished typing a reply to a thread, I click the SUBMIT button and BOOM, it takes that POSTING NEW THREAD or REPLY TO THREAD page and reopens it into a New Firefox Window;

well guess why is that Bad? Because the new page is blank!! Everything I typed is gone and the thread wasn't submitted to the Movie-List server!!

It also did the same thing while I was typing an email in my Yahoo Email and Google Mail;

I finished typing and click Send and BOOM AGAIN!! It reopens the whole thing into a New Firefox Window and I get a blank Yahoo or Google Mail E-Mail Entry Page!!

So I have to retype everything over!!

Why is this new Firefox doing that?

Reproducible: Sometimes

About the tabs opening in new windows,

If you accidentally click and drag on a tab, it will open in a new window, that's a feature. I find this especially happens if you have a lot of tabs open at once, depending on the content of each it will slow down your computer a bit (by using a lot of memory or CPU) and even the tiniest accidental dragging can cause the tab to go in a new window. I don't think this is a bug, it's just an annoyance. It happens on my sister's computer when she has 20 tabs open and uses 600mb of ram (her computer only has 512).
