Opera doesn't produce menu when I click right button or Menu button.
Started suddenly today.
Restarting Opera helps sometimes, not always.
I use latest stable version of Opera(88.0.4412.27) and Focal Fossa LTS.

@rockhen67 Its shame this isn't getting greater attention... First time during all these years I'm considering switching of browser.

I downloaded newest version from Ubuntu software application, enabled uMatrix... And it seems to have been fixed.

@cardcreed

Same here. Can't enable uMatrix extension without crash.

Yes.

Thank you for your help!

Latest stable Opera update broke Flash.
I thought it was supposed to go only in December?
I need it to play my online game.
(I use Ubuntu 18.04.5)

It seems to have gone on latest update, because I can't find it.
I have latest stable version and OS is Linux Ubuntu.

I wish we could have ability to report broken sites or at least, bring back old 'mask browser as Firefox'-ability.
(Sorry, English is not my first language.)

You find it from "settings". (second subpage from top, first being 'Browser'. I don't use English version of Opera, sorry.)
