Why does Firefox freeze and stop my computer?

  • 772

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

    Try this - close firefox, open shell and write:

    cd ~/.mozilla/firefox/YOUR_FIREFOX_PROFILE

    mv places.sqlite places.sqlite.bak && mv webappsstore.sqlite webappsstore.sqlite.bak && mv favicons.sqlite favicons.sqlite.bak

    This will delete/backup all your profile's history and web storage including cookies and web icons.

    Remove any unwanted or new addons that have been added just before the the problems occur.

    Restart firefox

    EDIT: if it's still freezes ,sluggish or hangs I recommend to removing your current firefox installation: sudo apt remove firefox (it keeps the profile intact)

    update to the latest build directly from mozilla's official PPA:

    sudo add-apt-repository ppa:mozillateam/firefox-next
sudo apt upgrade

    Install latest firefox build: sudo apt install firefox then run it firefox (without sudo) When the Icon appears on menu-bar right click and select Add to Favorites then you can run it directly using the UI.

    Good luck

  2. I had similar problem with Firefox. Using a Dell e6420. I rebooted computer, uninstall Firefox, opened another browser (windows browser), went to Firefox site and installed a fresh Firefox. Has worked for 3 weeks now.
