User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:105.0) Gecko/20100101 Firefox/105.0
Steps to reproduce:
Opened some pages, tried to reorganize tabs by moving a tab from one end to the other.
Actual results:
The tab moving animation, or the process is very jittery, it moves fine for a bit, then skips instantly to where my mouse is, resulting in an unpleasant jittery movement. The amount of tabs opened/addons do not seem to affect it. I have noticed this for a long time on firefox (probably over a year?) Until I tried doing it on linux, where this issue was not present at all.
Expected results:
It should have moved smoothly without any lag/jitter.

I have attached a recording of me producing the issue on a clean profile without any addons.

I tested the same on a completely different machine running Windows 10 pro and the same version of firefox and it seems to be present there aswell.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hello,
I wasn't able to reproduce this issue on my machine Win 10x64 using Fx 105.0.3, Fx 106.0 and Nightly 107.0a1 with a new profile(works as in Chrome). I noticed that you have another profile(with some addons) as default browser and after that you've created/opened a new profile.
Could you please check if the issue also occurs in troubleshoot mode?

The issue seems to be gone when I restarted it on troubleshoot mode. Both on the profile with addons (only ublock origin) and the fresh profile.

And it came back as soon as I disabled it.

I take back what I said, it still seems to be choppy even on troubleshoot mode, but just less so than normal.
On troubleshoot mode,
Heavy tabs with a lot of content (youtube video playback, frontpage of imgur), seems to still be noticeably choppy while moving it, while light tabs (google.com), seems to almost be completely smooth.
I have attached a recording of me trying troubleshoot mode and showing it (on a fresh profile with no addons or settings modified).

more info on this bug. it happens on all versions of windows 10. less severe on windows 10 22h2. and nonexistent on windows 11.
i was able to reproduce it on three machines running i5 7400, i5 2500k, pentium g2020.
might be something with older generation processors.
although it does not happen on windows 11, while running any version of firefox from a virtual machine inside windows 11 (vmware, virtualbox, etc), the bug happens without a fail.
it still happens on all recent versions of firefox.
