Was having a similiar issue, and this fixed it. Seems the easy file feature has a conflict with windows explorer. Anytime I tried to upload a file to any website, facebook, email, dropbox, youtube, etc. When I got to the step where windows explorer would normally open and allow me to select a file Opera and Opera GX both would freeze, unable to switch tabs or close the Opera windows/tabs. Also would occur when trying to save/download any files that required the windows explorer to open to select a file location.

Turning off easy files fixed this issue for me.

@sharkyca If the update happens without issues, only a couple of old versions are kept.

@rolnik u mnie jest nawet ponoć wyczyszczeniu przeglądarki usunięciu foldera z profil z dysku dalej to samo jest. Kiedy klikam daną stronę widzę zanim się wczyta pusta stronę i czekam z 3 Dec może dłużej jak wczyta na karcie widać że wczytuje Facebook wczytywał się dość szybko i inne strony a tu czekać muszę..

When you're on the site, hit ctrl + shift + i to load the developer tools. In the developer tools, click the kebab menu (3 vertical dots) near the top-right of the developer tools. In the Menu, goto "more tools" and then "Network conditions". The network condition settings will appear at the bottom. For the network condition settings, check "disable cache". Then, uncheck "select automatically" for the user agent. Then, in the user-agent drop-down, set Chrome for Windows. Then, hit ctrl + r to reload the webpage.

If things load correctly when you do that, it means the site is serving Opera broken code/HTML.

En el menú de Opera hay un apartado que dice Desarrollo, dentro de él otro que se llama Administrador de Tareas, hay podrás ver la memoria y la CPU que consume cada pestaña y cada extensión. También puedes poner la url de esa página en virustotal y que la escanee a ver si está limpia.

@leocg once try the Jiofi Local html to access the router
