Firefox Keeps Crashing Mac



Firefox keeps crashing, regardless of whether or not it is in safe mode. If I simply start trying to interact with a web page or visit another link, it will crash. However, this does not happen if I do nothing and leave it there. I have tried reseting FF, to no avail. Get all of Hollywood.com's best Movies lists, news, and more.

As a Dutch proverb has it: “Old foxes want no tutors.” Unfortunately, this is not the case with Firefox, which could benefit from some mentoring. A browser that is constantly crashing cannot be considered a mainstay of excellent browsing experience despite its other redeeming features such as security, pop-ups blocking or the fact that it is issued free of charge. Those who use Firefox on Macs or MacBooks all the time are well familiar with annoying crashes and regular freezing. So what are the reasons for the browser getting paralyzed?

Although the causes may vary, they fall into the following categories:

The user browses plugins-and animation-heavy websites, which have a lower than average loading speed, and put an additional burden on Firefox;

Poor browsing habits that are manifested in the excessively large number of opened tabs and windows;

Too many RAM intensive applications are running simultaneously, thereby slowing down the browser;

An old version of Firefox is used;

Unreasonably large size of the browser cache inhibits the optimal performance of Firefox;

A computer is slow in general.

What Can Be Done When Mozilla Firefox Not Responding on Mac?

After discovering why Firefox can be painfully slow, it is time to consider the avenues for improvement. Whenever the browser becomes totally unresponsive, it is a sure sign that one or several problems outlined in the previous section of the article have overwhelmed the once brawny and powerful fox.

The first recourse is to force quit the browser. To this end:

  1. In the Apple Menu, select the Force Quit option (you can also use the Command – Option – Esc combination);
  1. In the pop-up window, click on the Force Quit button to close Firefox.

If the entire system is frozen, it is necessary to make a hard reboot by holding the power button for a few seconds.

What needs to be done next is to open the browser and check its version. To do so:

  1. Click on the Firefox tab at the top of the browser’s window;
  2. In the window that opens, choose the About Firefox
  3. If you are using an outdated version of Firefox, it will automatically update itself.
  4. When the updates are downloaded, click on the Restart to Update Firefox button to initiate the installation of the latest version of the browser.

Ok, you have updated Firefox and try to use it to access your favorite website. However, after opening only a few tabs, it gets painfully slow and finally stops working altogether. Here’s a tested solution for this problem: try refreshing Firefox. The refreshing is used to restore the browser to its default settings, thereby improving its performance. To get rid of the drop in performance precipitated by misconfigured settings and the update, do the following:

  1. Click on the FirefoxMenu button and chose the Troubleshooting Information tab (alternatively, type about:support in the search bar);

After completing these steps, all add-ons and settings of the browser will be refreshed. It should also be mentioned that bookmarks, passwords, and browsing history will not be removed from Firefox.

If the browser can’t stand on its furry feet and crashes on startup, the problem might be rooted in outdated extensions. To check whether problematic add-ons are responsible for regular crashes, try launching it in the Safe Mode. To this end:

  1. Click on the Firefox Menu button;
  2. Select the Help tab;
  3. In the tab, choose the Restart with Add-ons Disabled option (another way to run the browser in the Safe Mode is to hold the Shift key during the launch).

If the browser runs normally in the Safe Mode, it is a sign that add-ons are responsible for the crashing. To disable or update the add-ons:

  1. Click on the Firefox Menu button;
  2. Select the Add-ons tab and proceed to the Extensions panel;
  3. Either disable or update each add-on;
  4. Restart Firefox.

To ensure that add-ons do not limit the functionality of the browser, keep them up to date by following the steps below:

  1. In the Firefox Menu, select the Add-ons tab and proceed to the Extensions;
  2. Click on the gear icon to change the update settings and select the Update Add-ons Automatically
