Con Cannot select tabs
Unlike in Chrome and Vivaldi, one cannot select multiple tabs to move to another/new window.
Con WebKit/Blink is not customisable or lightweight
Opera is built on WebKit/Blink, which means it shares cons of Chromium: high RAM usage (Not lightweight), lack of customizability.
Con Owned by a Chinese consortium
Who certainly need to conform with Chinese government requirements to let them infiltrate everything you do online.
While Opera is currently available gratis (without monetary charge), it is currently not libre (meaning that it does not allow users to view the source code used to create, to modify that code, or to redistribute modifications) and is therefor neither free nor open-source software.
Con Uneditable default search providers
It can not delete or replace already built-in search services such as Yahoo, Google, DuckDuckGo, and Wikipedia.
Con Same security-holes as Chrome
Opera uses the same browser engine as Chrome, meaning it has the same security-holes as Chrome. Chrome is a big target for hackers (being the most popular browser in the world), and a webpage that will hack Chrome will also hack Opera.
Con Unable to sync extensions
Imagine having 100 extensions and Opera link cannot sync them, which will be troublesome.
Some buggy or confusing behavior with the bookmarks bar and moving tabs, and entire windows turning black after a while.
Con Cannot stop auto update
Con Extension icons not directly moveable
Con Basically a Chrome clone
The latest versions of Opera are basically Chrome clones, so they really don't add anything new.
Con Needs user prompt to install from Chrome web store
Every time you install an extension, you need to say install first from Opera extension list to proceed.
Con No reader view
Con No address bar in fullscreen mode
Unlike in Vivaldi.

Con No menu bar

Sometimes, removing extensions won't work. Some websites downright refuse to load, no matter the settings.
Con Definitive unique browsing-fingerprint
Con Poor debian support
current versions miss support for debian-based distributions which is by far the most widely used group of linux distributions.
