Why does my Safari browser keep crashing?

Safari keeps crashing

Safari will keep crashing when you are browsing the web if your device’s CPU (central processing unit) is overloaded with too many requests to process different instructions at the same time. This will occur if you have too many browser tabs open. If these web pages contain a large amount of data that needs to be downloaded, the CPU on your Mac or iPhone will crash.

If you only have one browser tab open, and Safari is still not performing, it could be due to one, or a few of the following reasons;

Reason 1. Safari extension

If you have multiple, or even just one extensions enabled, it can interfere with your web browser loading successfully.

This could be due to the extension trying to block an ad or one of its certain features being faulty.

Reason 2. RAM is too full

If the RAM (random access memory) on your device has reached maximum capacity, your Mac (or iPhone) will take longer to process requests, resulting in Safari crashing.

RAM is one of the most important components in the performance of your device. It keeps the information your device is currently using so it can be accessed quickly, hence why Safari will crash if the program cannot get to its saved data.

Reason 3. macOS outdated

Your macOS or iOS software may be due to be updated.

When macOS has an update available, this will normally automatically include an upgrade to the Safari browser.

If Safari keeps crashing, this will be because your current operating system contains corrupted files.

Reason 4. Faulty cache files

Every time you open your browser and load web pages, cache files are stored on your device to save the information to improve the pages loading times.

These files can become faulty over time, and cause Safari to crash when trying to launch a web page.

Reason 5. Suspicious web page

Safari could be crashing because you are loading a suspicious web page that contains corrupted software.

There may be a virus or unsupported data that your web browser cannot process, without failing.

How to stop Safari from crashing

You can stop Safari from crashing while you are browsing the web by relieving the CPU on your device from too many requests that need to be processed all at the same time. This is done by closing down several open tabs on your browser, so only a few instructions need to be processed, rather than an extravagant amount.

If Safari keeps crashing on the opening of the program, or during the time you are on a web page even though you only have a few tabs open, you can fix this by actioning one, or all of the solutions that will now  be explained;

Fix 1. Disable extensions

You could have an enabled extension that is corrupted or causing conflict with your Safari web browser. If you have multiple different extensions turned on, they could be incompatible.

Switch your extensions off and see if this stops Safari from crashing;

Step 1. Launch Safari

Step 2. From the Safari menu, select ‘Preferences’

Step 3. Access the ‘extensions’ tab

Step 4. From the list of extensions, turn all the enabled ones off

Exit out of Safari before reloading your desired web pages.

Fix 2. Clear RAM

If you have too many applications or programs opened on your device all at the same time, your RAM will reach maximum capacity and start to slow down.

Close any programs you are not actively using while launching Safari. Before opening Safari again, restart your device to make sure all data has been erased.
