Reasons for removing one or another from a personal computer software there may be several. Changing the owner of a PC or updating the operating system, a radical way to reinstall the browser, even completely abandoning the use of a popular Internet browser. In this article we will try to explain several ways how to remove Mozila completely from your computer.

If we are talking about reinstalling, then first, the user should try a less radical solution to uninstall, and then. If the computer restarts, cleaning search engine from temporary cache files, cookies and history of visiting sites, as well as removing outdated additional extensions did not help, you can try to restart Firefox in safe mode without any additions. The next try, you can try to clear your browser.

First, you should try to restart your web browser in safe mode with disabled additional extensions, if there is no result, then the second option is to clean Firefox.

How to completely uninstall Firefox

Consider two ways to uninstall the browser - standard means operating system and auxiliary software.

Removing the program through the "Control Panel"

In the control panel, in the programs and components category, you need to find two objects that we are going to completely get rid of, namely the following:

  • Mozilla Firefox
  • Mozilla Maintenance Service

These two programs are deleted in the same standard way and similarity as most software. Right-click, select "Delete".

In some cases, the Uninstall Wizard may fail, then you can uninstall Mozila yourself by going to the following directory and using the "helper" utility.

"C: \ Program Files \ Mozilla Firefox \ uninstall"

Then check and delete, in case of detection, all folders named "Mozilla" or "Firefox". This is especially necessary if you want to delete all user data and settings from a personal computer.

C: \ Users \ user \ AppData \ Roaming \ Mozilla

Removing Mozila Firefox through special software

One of the most efficient and multifunctional specialized software is the CCleaner utility. With the help of this program, you can not only remove the Internet browser Mozilla Firefox with all its components, but also significantly clean the computer itself.

cclnr.ru - all the details about the advantages and capabilities of this tool can be found by clicking on this link.

You can also get rid of any mentions of Mozilla Firefox on your computer through CCleaner or by manually cleaning your PC in the registry editor ([Start] icon "=> in the search, type keyword=> button) => through search, deleting objects).

Mozilla Firefox is one of the main browsers. Why? Yes, if only because it is convenient for me to use it, in contrast to the same Opera, to which I simply could not get used to it after several years. I also like Google Chrome, but habits, you know, take their toll ... In the last couple of weeks, Firefox began to open too long on the first launch, and this despite the fact that I have far from the weakest "system". In principle, this is not news to me, since I faced a similar problem on my previous PC. Various methods, including deleting cache and cookies, did not help, so I decided to delete the browser and reinstall it again. Since I have very few bookmarks, I decided to save them to a text document and delete my profile along with the browser. By the way, if you leave your profile and export it again after reinstalling the program, then loading Mozilla will probably take the same long seconds as before uninstalling it, so it is undesirable to do so.

Now I will tell you how to properly carry out this procedure.

Browser removal instructions

If you decide to save some information, that is, bookmarks, logins, passwords and other data, then first use the MozBackup program, which allows you to save them and then transfer them to new profile... You can download it on the Russian-language version of the official forum. The utility is very easy and simple to use, so we will not describe how it works. By the way, never store logins and passwords in the browser, as they are easily stolen from there using the simplest Trojans.

If you decide to create a new profile, completely getting rid of the old one (recommended method), then just use our further instructions.

And yet - removing a shortcut from the desktop does not remove the browser, as some individuals think. Don't forget this!

Well, now let's proceed directly to the procedure.

As mentioned above, you do not need to remove the shortcut of the Internet browser from the desktop - this will not give you anything. It is necessary to delete the program using the built-in operating system Windows utility "Programs and Features", accessible through the "Control Panel" section. Click on "Start", then - "Control Panel" and "Programs and Features".

Find Mozilla Firefox, right-click on it and you will see “Uninstall”. Click on it.

Uninstall your browser by clicking the "Next" button.

Go to the Program Files section on your computer and find the Program Files \ Mozilla Firefox folder (usually located on the C drive). We delete it manually (either delete it to the trash, or use the SHIFT + DELETE keyboard shortcut).

Now you need to get rid of the temporary folders belonging to this program. For Windows XP, the directories are as follows:

  • \ Documents and Settings \ Username \ Application Data \ Mozilla
  • \ Documents and Settings \ Username \ Local Settings \ Application Data \ Mozilla

For Windows 7 or Vista:

  • \ Users \ Username \ AppData \ Local \ Mozilla
  • \ Users \ Username \ AppData \ Roaming \ Mozilla \

Everything? Alas, this is not the end. Now you need to remove all the tails left after uninstalling the browser. We go into the registry editor ("Start" - "Find all programs and files" - Regedit) and delete the following elements in the directories:

  • HKEY_CLASSES_ROOT \ FirefoxHTML
  • HKEY_CURRENT_USER \ Software \ Mozilla
  • HKEY_CURRENT_USER \ Software \ MozillaPlugins
  • HKEY_LOCAL_MACHINE \ SOFTWARE \ Mozilla
  • HKEY_LOCAL_MACHINE \ SOFTWARE \ MozillaPlugins

True, some keys may be missing. This is completely normal.

If you do not want to use the registry editor, then you can use any third party utility, which will remove all unnecessary "tails" in the system. For example, . I recommend using it if the terms like you don't mean anything. Plus CCleaner is completely free to download.

Download CCleaner, install it on your computer and run. Select the "Registry" section, click on the "Search for problems" button.

The utility will find the necessary data, including the "tails" left after removing the browser. On the right side of the window, click "Fix".

Only now, after completely removing the browser, you can reinstall it and export all saved files (or do absolutely nothing).

Sooner or later, the efficiency of the browser decreases and something new comes to replace it. It is because of this that everyone should be able to pull out the unnecessary from memory and add the necessary. The possibility of elimination will be considered using the example of the Mozilla Firefox application.

Eliminating unnecessary content from a multimedia device is a long time ago. But not everyone has figured out how to get rid of uncomfortable software. Mozilla Firefox on a personal computer or a modern gadget can be eliminated equally easily, but the algorithm for each individual working mechanism will be different. Now it is these values ​​that should be understood.

Neutralization process on the computer

Experienced programmers are well aware of how to completely remove smear from a computer, but since you don't want to run somewhere with such a question, you should learn how to make the process of such a sample yourself. To accomplish the task of the presented nature, the adjustment adjustment algorithm will be as follows:

  • enable the start-up system on the Windows device;
  • open the Control Panel;
  • find the right software component and select it;

Functional adjustments of this nature will be confirmed by restarting the computer device. If the removal was unsuccessful, you need to seek professional support, where everything will be done competently and quickly. All processes of this type will be irreversible. After the browser has been completely disposed of, it will need to be reinstalled using the application store for this purpose.

If for some reason you decide to uninstall Mozilla Firefox, then we will help you do it. The reasons, in fact, may be different, but one of the most common is. Then it takes complete removal and installation from scratch. But it may also be that the person just decided to change the browser to another.

It is very important to remove the browser correctly so that there are no "schemas" left of it. Otherwise, in the future, when reinstalling, they can lead to various kinds of errors and program bugs. And they can simply slow down the operation of a computer, especially if the computer does not have outstanding technical characteristics.

Then, in the window that opens, enter into the line “ Regedit”. This will open the registry editor, which we will use to delete the remaining files.

In the registry editor, we need to find the following folders and delete them. These folders can be found in the specified paths (column on the left):

  • HKEY_CLASSES_ROOT \ FirefoxHTML
  • HKEY_CURRENT_USER \ Software \ MozillaPlugins
  • HKEY_LOCAL_MACHINE \ SOFTWARE \ MozillaPlugins
  • HKEY_CURRENT_USER \ Software \ Mozilla
  • HKEY_LOCAL_MACHINE \ SOFTWARE \ Mozilla

All these folders must be deleted, if they are not there, then nothing needs to be deleted. If you don't want to search manually, then just write the paths in the search. Go to the tab “ Edit"And open the link" Search”, Where enter the directory address.
