I searched in previous answers and I did not find an answer. Maybe he does not search in the right way. The problem I have is that working with my PC, ACER 5620Z, is going well. But when I start Firefox, it freezes, and makes the other applications I have running, also freeze. I tried disconnecting the SWAP, but the problem continues and I do not know what else to do. If you give me any idea why it can happen. Maybe I should uninstall and reinstall? The problems I have had since I did something to put Firefox in Spanish, but I can not find the exact documentation to give them more information. The Firefox version is 61.0.1 Mozilla Firefox for Ubuntu. canonical - 1.0 Maybe I should install Google Chrome better?
EDIT: When I start Firefox and Visual Studio Code at the same time is when the pc freezes.
I'm taking my first steps in Ubuntu, and I still have to learn. Thank you
