How To Fix FireFox & Errors
Step 1 – Restart Your PC
The first step to resolve this problem is to restart your PC. FireFox has been designed very well, and as a result, it may just be a slight glitch or problem that could be causing the crash you’re seeing. If you’ve only experienced the issue once, a restart could be all your PC needs to refresh the settings, files & options it requires to run, fixing the problem for you. Restart your PC, and if you see the problem occur again, then you should proceed onto step 2:
Step 2 – Re-Install The Mozilla FireFox Application
If you restart your PC and still find your system is unable to run FireFox, you should then re-install the program. This will not only allow your computer to better read the files it needs for the software, but will reset any damaged or incoherent settings that may have been causing some problems. To do this, you should follow the steps here:
- Click “Start > Control Panel > Add / Remove Programs”
- Locate “FireFox”
- Click UNINSTALL next to it
- When the application loads, select “REMOVE” (not repair)
- Follow the uninstall process
- Restart your PC
After you’ve done this, reinstall FireFox from a fresh download, and then test out the application. If you find the problem still occuring, you should then proceed onto Step 3:
Step 3 – Remove Add-ons & Plugins In FireFox
Add-ons are a great addition to Mozilla FireFox, allowing people to customize their application in ways which have barely been known before in software development. Although these are good, they can often cause FireFox to crash, making it vital that you remove any add-on you have installed with FireFox in order to ensure it’s able to run smoothly. Here’s what you need to do:
- Open up Mozilla FireFox
- In the top menu, click Tools and then select Add-Ons
- Click Uninstall, or Click Disable if you think you may use the addon in the future.
- Restart your browser.
This will remove the add-ons which may be causing a problem for you. If you do this and find the problem still exists, you may wish to then proceed onto Step 4:
One of the most common problems that can lead to Mozilla FireFox crashes is down to the “registry” of your PC becoming damaged or corrupted. This is a central database of Windows which stores all the files, settings and options that all your software uses to run. FireFox stores a huge number of settings inside the registry database, and is continually trying to load them all up whenever you attempt to use the program. However, because so many registry files are required to run the software, it’s often the problem that Windows will either be unable to read the files that it needs or will just skip over many important settings. You can resolve this problem by downloading and scanning with a registry cleaner program. This should solve the problems you have for good.
The best way to fix this problem in the most effective & reliable way is to download a registry cleaner and then let it scan through your PC. Not many people know this, but the “registry” of your PC is one of the biggest causes of problems for Windows systems, as it’s continually being used by all your software to help your computer run. FireFox is so complicated & advanced that any corrupt setting inside the registry could cause it to crash, making it recommended you fix the problem by using a registry cleaner tool to scan through your PC. You can perform this process by using the tool below:
