Mozilla Firefox Hangs on Windows 10

 Freezing or Hanging is a process where a program stops responding to a user’s input. A hang or a freeze is different from a crash. A Crash ends the program, and the windows automatically shut down. The reasons can be many. It could include the installation of incompatible themes, extensions, or programming errors in plugins. I am suggesting some troubleshooting steps which you could follow in case you find that your Firefox is giving you problems in Windows.

1. Bad Firefox Add-on

My next suggestion would be for you to open Firefox to Safe Mode and check out if you have any bad add-ons installed. If the Firefox browser freezes without any warning when you type something or click on a button link, close all the tabs and start Firefox in Safe mode.

To do this, open the Firefox browser, click on the Settings button in the top right corner. Next click on the small blue circular question mark sign. Next, select Restart with Add-ons disabled.

 Now, if Firefox runs without freezing, it suggests a bad add-on – either an extension or toolbar – some extensions are prone to memory leaks.

 2. Update Adobe Flash version

  • If you are facing freezing or experiencing a  delay while starting Firefox, you might want to check out if your Adobe Flash, Java plugins are up-to-date. Some versions did cause Firefox to freeze or crash. 

3. Check Windows shell extensions

Some Windows shell extensions can also cause problems with your Firefox Hangs, causing it to freeze or crash. You can use ShellExView to see all the explorer shell extensions and then try to selectively disable extensions which you suspect could be the cause of your problems.

4. Extensions of 3rd party software

Extensions of your antivirus, security suite, site advisors, password manager, download managers could also be a possible cause. Again, disable each one selectively and see if you can identify the offending issue.

5. Create a new Profile

The Firefox User Profile Manager allows you to create an additional profile. Create a new profile in Firefox and transfer all your settings and other data to the new profile, and see if it helps.

6. Reduce Firefox memory usage

You may also want to consider reducing memory usage of Firefox by changing the about:config preferences. You may especially want to tweak these settings:

  • browser.cache.memory.capacity,
  • browser.cache.memory.enable
  • browser.sessionhistory.max_total_viewers settings.

Do so only if you know what you are doing. Reducing memory usage by carrying out just tweaks, removing themes, Personas, and reducing add-ons or plugins can also help you resolve your problem.
