Hi,

since some time I experience on both Linux and Windows XP some very annoying behaviour of Firefox.

I am regularly using plenty of tabs with different locations. I am changing between those windows often, just by clicking on the tabs. But since I installed the newer versions of Firefox (it seams to me), I regularly get a drag icon when I just want to click. It seams, that I just clicked a little bit to long and dragged a little tiny bit ... but that is enough that I get this anoying sticky thing on my mouse. I just don't want it! So I try to get rid of it -- but then Firefox reloads the actual window -- something I also don't want! It is very annoying for me.

Is it possible to deactivate this stuff or to make it less sensible? More functions is good -- but I am working with this stuff ... and in 99.99% of all cases, I just don't want to drag anything (I even don't exactly know what it's use is) and just ... click.

I thought, I report this stuff, because as big fan of Firefox I want it to be the best Firefox it could be!

Best Regards,

Reproducible: Sometimes

Steps to Reproduce:
1. Have multiple tabs (tabbed browsing)
2. Change tabs by clicking on a different one -- be inprecise (like in a hurry)
3. Watch drag icon and try to get rid of it (when I do it, I drop it on the same window and it just reloads (annoying!))

Actual Results:  
Drag icon will be activated (not wanted it)

Window reloads, when I release it on the same window/tab

Expected Results:  
When I click, I don't want the drag icon -- it should be less sensible!

Or: is there a way to deactivate this "feature" (I just don't need it)

It seams to me, that the drag icon also comes up when I click on some pictures with links or even links themselves. This is also annoying but happens less in my case.

I see only the drag indicator when I drag below the tabbox or when I pass the border between two tabs. The click lock in the mouse properties makes unwanted dragging easier BTW. Or maybe there's something wrong with mouse or driver?

Additional info:

You can easily reproduce the problem, by intentionaly clicking on a tab and then drag a little bit with pressed mousebutton. Then the drag icon appearse and you can for example change the order of your tabs by dragging the icon across the tab-strip.

My problem is that it happens even unintentionally very ease (approx. in one out of then clicks on the tab-strip).

... and No, my mouse-driver has no problem! It happens on two very different platforms (Linux (at home), Windows XP (at working place -- installed by the IT staff)).
