opera.com é seguro?

De la grosse merde ce putain de navigateur, il plante sans arrêt, me pompe la mémoire machine, similaire à l'autre merde de Chrome, auquel il a tiré son code source. Ses extensions sont obsolètes, notamment pour Youtube, même WOT est vieux sur ce navigateur. Il me perds régulièrement tout ses onglets et sa session, sans historique ni récupération! Cette saloperie se mets à jour sans ma permission même en s'emmerdant à tout désactiver même dans les tâches planifiés de l'ordinateur, cette daube remets tout par défaut à mon insu pour se mettre à jour et planter, sa suffit, je suis passé à Firefox!

WORST browser ever, Youtube not working, I try to bypass my ISP throttling (thanks ISPs with no neutrality politics) with proxfree, not working again! Why, video players not updated. Lost all tabs with bugs, no session recovery! NO VISIBLE option to restore closed windows with tabs (need to go to a tabs menu to see a possibility to reopen closed windows but it's confused)! Other things, lot of addons not compatible with opera like Google search filter (personal blocklist).... Opera can freeze or crash with high risk to lost all tabs (opera less lag with it's newest versions at date of 03-09-2017 but ads bypass easly Adblock Plus, µBlock... on Opera and Chrome browsers, why?)! On mobile this browser is more worst, NO adblocker addon possibility, lots of ads not blocked, Youtube is an ads paradise on Opera mobile. I lost all my tabs when Opera crash! Avoid it.

I do enjoy and use opera on a practical basis. They seem to keep their browser properly updated and gives you various 'plug-in' options. If you are used to firefox and google chrome there are many aspects that will give you a similar type feel, yes it is different.
