Mozilla Firefox Won’t Open – Nowadays people around the world seem inseparable from the presence of the internet.

Every day there are many people who spend hours just surfing the internet, either opening certain social media or completing work.

This, of course, is something that is reasonable because the internet has now become part of the needs of society. As long as it doesn’t interfere with other activities and become addicted.

How To Fix Mozilla Firefox Won’t Open

The presence of the internet has a tremendous positive impact on its users. One of them is that people can easily get various kinds of information that can increase their knowledge.

Now surfing the internet can be done very easily because there are various kinds of internet browsers available.

One internet browser software that is very popular and widely used by the public is Mozilla Firefox. This software can support your needs in finding certain information on the internet.

In use, Mozilla Firefox has many advantages because it provides add-ons that add functionality to the browser.

However, this browser also has a number of shortcomings, such as not found servers, not responding, and software that can’t be opened.

Causes of Mozilla Firefox Cannot be Opened

Before that, it’s good for you to know some common causes that can cause Mozilla Firefox can’t be opened in daily use.

The first is…

1. Firefox.exe Status is Still Active

I put it in point number one because this is what happens the most.

Sometimes we don’t know that Firefox that has been closed is actually still active in the background which results in “minor conflicts” in software between Firefox and Windows OS.

This “still active” state of firefox usually occurs due to an ongoing background update but is not finished due to a bad connection.

Now that’s why Firefox is usually still active continuously, then the user (you) re-click the Mozilla program which will cause the Windows OS to be confused.

This confused OS state is what ultimately makes the program process longer, OR doesn’t even respond/open at all. (especially with the amount of RAM only 2GB, it’s complete)

Something like that … Does it make sense?

2. Program Files are Damaged/Corrupted

The second possibility could be that the exe file program from Mozilla firefox installed on the PC / Laptop that you are using is experiencing file damage or what is usually referred to as corrupt.

The state of this corrupt file can be caused by a hard drive that is already getting tired and is no longer able to perform perfect read/write tasks.

OR, it could also be caused by a virus that has damaged the Windows OS system which makes some programs into errors and can no longer be used properly.

It is still better if only 1 or 2 corrupt programs are infected with a virus. But what if the infected is already in the scope of the Operating System?

Of course, the only best way is to reinstall the Windows OS.

Of course what must be fixed is the OS, aka Windows. (if it is damaged in the Operating System)

3. Too Many Add Ons

The possibility is small, but it could also be this small thing that causes Mozilla Firefox cannot be opened because of “objections” due to too many Add Ons installed on the browser.

Too Many Add Ons

Please remove/reduce some Add Ons / extensions that are not very important and are rarely used.

4. And Other Errors …

There are still many other possible errors that could potentially cause the inability to open the Mozilla Firefox browser on Windows 7, 8, and 10.

Starting from the error that Firefox cannot be opened, Firefox has stopped working, and other problems, of course, the restrictions and causes will also be slightly different. -different. (it depends)
