Steps to reproduce:

Use a gaming mouse with a polling rate of the USB port equal to 1000 Hz.


Actual results:

Moving tabs on the tab bar occurs with strong performance issues.


Expected results:

Moving tabs should be as smooth as in Chrome. At 125 Hz the smoothness is dramatically improved!

Based on the fact that I don't have a mouse like this for testing, I can't test it. I will move it to widget: Win32 since it seems to be specific to windows hardware support.

Can you please try something: 

Please download the Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem.

If you still have the issue please create a new profile, you have the steps here:https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

Please test if the issue can be reproduced in the safe mode of Firefox: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

The problem exists in Safe Mode too.
The same problem occurs in a new tab when you try to move the thumbnails.
Just try ANY mouse with a Polling Rate of 1000 Hz in your browser. That's all. It's simple ;)
Really none of the Mozilla Corporation employees do not have a mouse with a Polling Rate of 1000 Hz?! O__O
Seriously???
 Hi 5silentrain,

When I said that I don't have that kind of mouse I was referring to myself. That is the reason way I move this issue to a component without testing it.

Except you no one else can verify this bug??? o_O
I am not the only one, let see what the developers from this component can tell about this issue. Thanks
OK :)
Someone from Mozilla employees confirm this bug which is not fixed for many years?
The bug is present in Firefox Nightly and all versions of Firefox!!!

Hi 5silentrain,

I have tested your issue with a mouse capable of 1000 Hz poll rate and I have found the following on the latest Nightly:
With 4 tabs opened and the mouse set at 125 Hz, while moving tabs CPU usage is at about 12-15%.
With 4 tabs opened and the mouse set at 1000 Hz, while moving tabs CPU usage is at about 20-25%.
With e10s enabled and disabled I haven't observed any performance issues while doing this.

However, I opened a lot of tabs in order to raise the CPU usage (around 30 with 10 YouTube videos). This brought the CPU usage to 70% after it stabilized. Moving Tabs and the New Tab page tiles does show some lag and CPU usage further increases to 90%. This is both with 1000Hz and 125Hz. 

Seems to me like this is a more general issue related to CPU and RAM load and not something strictly related to the mouse polling rate. Indeed 1000Hz rate does help to see this better but it does almost the same with 125Hz in the same conditions.

Ever confirmed: true
It would be great if the smooth of moving tabs on the tab bar was the same like in Chrome and Opera =(

After buying a new computer (Intel NUC Hades Canyon (HVK)), the smoothness of moving tabs has increased dramatically 👍 Now I have no complaints about the smoothness of moving tabs.

The bug is still present even in the most recent dev version (89.0b4) 😢 Please someone fix this behavior by making the tabs move smoothly 🙏

P. S. Everything is smooth in Chrome 👍
