thank you for the reply, I didn't do a clean install/reset settings, but I tried to disable extension one by one and it seem the uBlock Origin extension is the cause of the error and not compatible with version 67.0.3575.115, well I should temporarily turn it off until there is the next update
@jmc5221 - I also want the previous menu position at top brought back. it is the obvious location for the most commonly picked option in this list (at least for me) and the biggest reason why I use Opera instead of Chrome. This is one step farther away from older Operas' super easy image saving key combo of "Shift-click" on the image.
@burnout426 thank you for the reply but it looks like it's very complex and seems to be for expert users.
I have never had this problem before, I think the old version of Opera (I forgot what version) is better when there is an option to delete the autofill history individually but the developer seems to delete that feature now
