firefox high disk usage windows 10

Reddit users reported that the new Windows 10 v1903 is causing a spike in the disk usage when switching between Firefox tabs.

I don’t know if this is a me problem but since I updated opening or switching between tabs in Firefox now spikes my disk use and is making my laptop unusable. I am uninstalling the update if that doesn’t work then I will try rolling back FF to see it that is the problem. Nothing worse then two major updates when trying to figure which is the cause. Finished uninstall of windows update and restarted, problem fixed. Disk usage back to normal.

As you can see from the message, the problem made the laptop unusable, as disk usage needs to be relatively low.

However, the user doesn’t specify if the issue appeared on other web browsers as well.

This might be a problem triggered by incompatibility issues between a new Windows 10 v1903 feature and Firefox.

If you don’t want to revert the changes and keep on using the latest Windows 10 version, you can temporarily switch to a different browser.

If the problem disappears, this means there was indeed an incompatibility issues there.

Users confirmed that rolling Windows 10 v1903 back solved the problem, but we still have no clear as to what initially caused this issue.
