It's very annoying when I try to ctrl+v for paste something, or ctrl+c to copy something. Ctrl in Firefox deloper tool (Ubuntu 16.04) will always work like "escape" key. Even I switch to default English IME, cursor will not focus on that input selection.

It happened not only on developer tool, but also on right top plugin window. The problem can't not replicate at windows 10.

I found the problem. It's from Ubuntu / Gnome system. Problem solved by just turn off “show mouse when press Ctrl” in Ubuntu settings. Askubuntu have tutorial for how to turn off this option: https://askubuntu.com/questions/230102/how-do-i-turn-off-show-mouse-when-i-press-ctrl

I switch to use safe mode, but the issue still exists. Needs video or gif?

All the checkboxes under "Firefox Data Collection and Use" is checked.

Can you at least open the right-click context menu and use that to copy and paste?


Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.
