Xul.dll is a file used by Windows computers to help them run the "FireFox" program. This is a leading web browser which is currently one of the most popular in the World. Although FireFox is famed for its smooth operations and features, the fact is that it's continually causing a large number of errors because the xul.dll file it relies on can either become corrupted, missing or damaged. To ensure that you can fix the errors caused by xul.dll, you need to be able to repair the various issues that can cause them to show.
The errors which xul.dll normally shows include the likes of:
XUL.DLL is not valid without reinstall
This application has failed to start because xul.dll was not found. Re-installing the application may fix the problem
This error is normally caused by the xul.dll file either being outdated (incompatible with your current version of FireFox), or it is corrupt & unreadable. The first thing you should do to repair this issue is to reinstall the Firefox web browser in its entirety. This can be done by totally uninstalling the browser from your computer and then reinstalling it. This should place a fresh version of xul.dll on your PC, allowing Firefox to read the files it needs to run, fixing the error.
You should also clean out the "registry" of your system to make sure that all the parts of it are not causing any problems. The registry is a central database that Windows uses to help store all the files and settings for your PC, and is what every Windows computer uses to help it recall numerous important settings that it requires to run. Unfortunately, the registry is also a big problem for many Windows PCs because of the way it's continually being saved in the wrong way. The big issue for programs like FireFox is the way in which the registry stores a large list of "DLL Files" for your computer. This list allows various software programs to read the files they need to run, making it essential that it's intact and reliable. Unfortunately, this list is continually being damaged, making it vital that you're able to repair it by using a "registry cleaner" program.
