CTRL+O Not working on firefox 77.0.1(64-bit) Debian 10
I don't know why, but when I try to open a file in firefox 77.0.1(64-bit) It's not opening even though I navigate to file -> Open File, it's also not working, even though I press ctrl+o it's also not working. Am using Debian 10.
Some background, Debian default is Firefox ESR which works flawlessly, but it's missing my favorite Firefox feature Screenshot, i take a lot of screenshot in a typical day, of the web stuff am doing. So what I did is to install another Firefox using snap, and it has it(screenshot), but this snap Firefox's CTRL+0 does not work. Even the File -> Open File does not work.
