@leocg yes i did

so i had about 130 tabs within 3 windows opened, when i attempted to quit opera, it prompted a warning but said that it would restore all of them. however, only 2 windows closed and the last remaining window with 10 tabs remained opened. when i tried to close again and reopen, only the last window with 10 tabs restored, trying to restore the remaining 120 tabs were unsuccessful

seriously, if you said that you would restore it, then do it and don't lie

guess i will never use opera again

for those who ask why didn't i bookmark them, it's because why should i bookmark if i have a option to leave them open and restore them when i come back? if this feature is so unstable, why should this feature be here in the first place
