v1.6.689.34 (Stable channel) (32bit) Crash due to HTML5 popup message window
Since Vivaldi update 1.6 i'm reliably able to reproduce a crash with HTML5 popup window from Facebook or Slack (didn't test any other).
This crash only happens if there is other fullscreen app (even second Vivaldi instance) in-focus (so the popup is not visible). It also crashes all existing Vivaldi instances along with the one spawning the popup window.
Installed extensions are: Adblock, Stylish
I've also disabled these and did re-test with same results.
If anybody can try this (i'm not able to find any info about similar crash anywhere on this forum). I can re-test this on different machines if necessary tomorrow, all running Win7/Win10.
I'm experiencing the same problem.
Installed extension: Ghostery/adblock/toolbox/RES
I also encounter this.
