freeze while browsing

If the whole computer froze and even the cursor stopped responding, I wouldn’t assume Firefox itself caused it. Next time, give it a minute first. If nothing responds, try''' Ctrl + Alt + Delete. '''If that doesn’t work, a long press of the power button is about all you can do. To prevent it, I’d start with Firefox’s Troubleshoot Mode and see if the freezing happens again. If it stops, an extension or hardware acceleration is a likely culprit. If it still freezes, I’d check the''' graphics driver, RAM usage, '''and '''Windows Event Viewer''' for errors around the time of the crash. If this starts happening regularly, it’s worth troubleshooting the computer itself rather than just reinstalling Firefox.
