I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.

Hi Barbara

How many tabs do you have open?

Do you have any add-ons installed in Firefox?

Hello

Task Manager - see whether tabs or extensions are slowing down. https://support.mozilla.org/en-US/kb/task-manager-tabs-or-extensions-are-slowing-firefox
