Safari has many webkit crashes

Safari vs Firefox (Safari has many webkit crashes)

Running macOS 11.7.10 Big Sur

I found in: ~/Library/Logs/DiagnosticReports/ many (70) crash reports of Safari.

I removed them and the next day the folder was filled with fresh Safari crash reports.

pointing at: Process: com.apple.WebKit.WebContent [3921]

Crashed Thread: 4

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000

Exception Note: EXC_CORPSE_NOTIFY

Termination Signal: Segmentation fault: 11

Termination Reason: Namespace SIGNAL, Code 0xb

Terminating Process: exc handler [3921]

And much more information.

As I am unable to find the cause of the crashes, I started using Firefox and there was not a single crash.

Has any one experience with this phenomena? Could there be a solution for the issue?

I am using Safari for many years and I don't want to use another browser but because of the crashes, I have to.

MacBook Pro 15″, macOS 11.7

Any Safari extensions, add-on firewall apps, add-on VPN apps, add-on security apps, or similar, installed?

I was referring to trying the websites on a newer version of macOS, yes. Safari on macOS 11 is getting old.

so, there is not much I can do.

Is the issue manifesting somehow? Other than diagnostic logs, that is.

Alternatively, I could use Firefox permanently bc that browser doesn’t crash.

Waterfox, Vivaldi, and other choices, as well. Or if Safari isn’t doing anything noticeably wrong, keep using it.

Try the problem websites on a newer version of Safari?

Avoid the sites that cause Safari to crash? :)

Seriously... it might help if you posted the sites in question. That way others can test/verify if it's common to that site, or limited to your setup.

Well, I am using Firefox now and it works fine, it is just that after so many years of using Safari, it looks unfamiliar to me.

About the crash-sites, I will register a site when it crashes on Safari.

But as said, Firefox is stable and doesn't crash and therefore I will have to get used to the browser.

The bottom line is that Big Sur is outdated.
