Sqlite cache needs updating
This page content has been ripped out of my Firefox Customizations (Notes) page to make it smaller, and so that problems are basically on a different page than notes about extensions.
Some problem solving material remains on the main page that provide solutions for problems that would not likely be viewed as problems but as alternatives such as how to make Ctrl U Open into Notepad, additional notes on blocking ads besides extensions.
If Firefox will not start, first check to see if FIREFOX.
EXE is already running by checking your running tasks — ctrl alt del, Task Manager, Processes.
If it is already running then terminate that task and try again, this usually gets you back.
Don't know where this came from, but when I hover over an image this shows up, and it is annoying, covers up text, and even worse often gets stuck and won't go away.
Seems to match description of various “floating image toolbar” extensions -- but I have no such extension installed that I know of.
