Status: New idea

Please fix the skinny scroll bars in Thunderbird.  I have tried everything in the about:config to no avail.  I can't go on with them having a thin width.  And keep them visible.

@dwmusic: There is a way to fix the scrollbar width, which works in TBird and most (all?) other apps in Windows 11 (I just tried it, don't forget to log out or restart to make your change take effect):

https://www.groovypost.com/howto/make-scroll-bars-wider-in-windows-11/

I set mine to -700 just to make sure it works, and it does.  I prefer a number around -165 or -180, but ymmv.  

Another way to adjust this is to use Winaero Tweaker (freeware program).  'Under Advanced Appearance Settings'/Scrollbar are two adjustments, one to set the scrollbar width, the other the size of the scrollbar "buttons" size.  I'm not totally clear what adjusting the button size does, but the Scrollbar Width sounds like what you're asking for.  I forget what setting I had before I tweaked it with Regedit, but I think the number was like 30.  (There's no clear mapping between the number in Winaero Tweaker and in Regedit, afaict.)

@dwmusic  I tried to post a fix to this, but it's not showing up.  Not sure if that's an intentional delay.  The easy fix is to use Winaereo Tweaker.  Let me know if this doesn't show up, and I'll try re-posting.

Windows 11 Settings always ON, & then Regedit works for me, as published in

Is there a solution for macOS? I am running Sonoma 14.3.

I don't know about the macOS setting, but @cnckeith in Windows 11 the fix is in Windows itself, not in TBird, which just defaults to the Windows setting.  See Weqas' ‎04-10-2023 11:16 PM post for the fix to the disappearing scrollbars, and my ‎01-29-2024 06:19 PM post for the fix to the skinny bars.

Thanks,  Agentvirtuel

I carried out the steps as per screenshots attached, and restarted Thunderbird to make sure the edits were recorded but the scrollbars look the same skinny width, as per screenshot.

What do you suppose these edits were actually changing? I could not see any difference in the GUI at all after making them.
