[Bug 2033988] Re: Firefox Snap update breaks dark themes

[Little Girl]

** Description changed:

  * Operating System: Kubuntu 22.04
  * KDE Plasma Version: 5.24.7
  * KDE Frameworks Version: 5.92.0
  * Qt Version: 5.15.3
  
  I would expect to be able to have full access to my bookmarks and the
  contents of the application menu regardless of the theme I am using.
  
  That was the case until I allowed the Firefox Snap to update. I closed
  Firefox to allow it to update itself when I got the Snap notification in
  the bottom right corner. I then ended up with this version:
  
  Firefox 117.0 (64-bit)
  Mozilla Firefox Snap for Ubuntu
  canonical-002 - 1.0
  
  The current version breaks my dark theme so that I cannot see my
  bookmarks or settings. The bookmark icons are visible, but the text is
  invisible on the dark background. Hovering over the bookmarks displays
  their tooltips and the bookmarks can be successfully clicked to open
  their pages. The application menu (that you get to by clicking the
  hamburger icon in the top right corner of Firefox) has no tooltips. You
  can still click on its entries, but you'd have to know which one you're
  clicking somehow or you're taking your chances.
  
  This appears to be a theme issue. I was using a dark (magenta) theme
  when the update occurred. When I switch to a light (pastel) theme, the
  entries in the application menu are visible and the text inside of
  toolbar bookmark folders is visible. However, text is still *not*
  visible in the bookmark manager. Interestingly, the bookmark manager is
  not honoring my current light (pastel) theme even after a restart of
  Firefox. Instead, the bookmark manager is still displaying with my dark
  (magenta) theme. This means that thorough searches of the bookmarks and
  manipulation of the bookmark contents is not currently possible.
  
  Some additional notes:
  
  * I tried replicating the issue in a virtual machine and wasn't able to,
  so I suspect something went wrong with the update on this machine.
  
  * I tried several dark and light themes and all of them exhibited the
  behavior described above.
  
  * Closing Firefox,  deleting everything in the
  ~/snap/firefox/common/.cache/ directory, and reopening Firefox has no
  effect on the issue.
  
  * Revision 3068 is the currently-broken revision I'm using and revision
  3026 was my last-known-good revision, so something broke in or during
  the update to revision 3026.
  
  * Reverting to the previous revision with the sudo snap revert
  --revision=3026 firefox command does not affect the issue.
  
+ * The issue does not exist If I log in to Kubuntu as a different user,
+ even when switching between light and dark Firefox themes.
+ 
  I've attached the output of the snap list --all command and also these
  five screenshots to show that toolbar bookmark text is only visible when
  using a light theme, that bookmark manager text is never visible, that
  the current theme is not honored in the bookmark manager, and that the
  application menu text is only visible when using a light theme.
