have to say a much better-stable version than my previous installed.
Opens/supports a good choice of sites as linkedin, youtube, gmail, my company organization email, OS2 World Forum ad others.
2-3 browsing windows opened same time smoothly running, and when it reaches the maximum work limit (4-5 browsing windows same time) program just quit, no system traps as it did before.
Also when exit/close the program no system traps as it did before.
Good job, right direction.
this above was a successful test on a virtual machine (Virtualbox guest Warp 4.52) where I separately installed all QT5 environment and latest Python needed, with a standalone Dooble version learned on this forum in 2022 (not rpm). Swapped that executable version with this latest one , now well working as said.
Tried on another virtual machine with no previous QT5 environment installation wich now came by installing Dooble rpm package, and then swapped its executable with this latest, it normally opens/navigate any site after first run, but next time it does not resolve IP addresses anymore, like something prevents the translation. Do not understand which could be the cause.
