[Desktop-packages] [Bug 1675496] Re: Scrollbars are tiny in Firefox 52

2018-02-27 Thread Jan Rathmann
The described issue with the scrollbar size still exists on Bionic (and
all newer Firefox versions).

** Changed in: firefox (Ubuntu)
   Status: Invalid => Confirmed

** Summary changed:

- Scrollbars are tiny in Firefox 52
+ Scrollbars are tiny in Firefox (since FF 52)

** Description changed:

+ == Update 2018-02-27: While this report was created for Firefox 52 under
+ Ubuntu 16.10, it is still valid for all newer Firefox version/Ubuntu
+ releases. ==
+ 
  In Firefox 52, the size of scrollbars has become smaller so that it is
  really tiny and hard to grab by the mouse. For me, this is a usability
  issue.
  
  The scrollbars were considerably bigger in Firefox 51 and previous
  releases. To illustrate this, I have attached two screeenshots for
  comparision between Firefox 51 and 52.
  
  While other GTK3-applications (e.g. Gedit) also have very slim
  scrollbars, they on the other hand have a mechanismn that makes their
  scrollbars broaden automatically when you move the mouse over them, so
  grabbing them isn't an issue. If the same would be possible in Firefox,
  this would of course be also an acceptable resolution.
  
  Kind regards,
  Jan

Yes, this would be an acceptable solution, but on my system (Yakkety) the 
scrollbars in Firefox always stay slim and never broaden, regardless if I move 
the mouse over the slider or some other place on the scrollbar. Is this 
different on your installation?

2017-03-24 Thread madbiologist
In Gedit the scrollbars broaden automatically when you move the mouse
over any part of them.  In Firefox they only broaden if you move the
mouse over the slider.  Inconsistency is not good, but this is probably
an acceptable solution.  What do you think?
