Why do my tabs keep crashing Firefox? 

If you’re using Firefox, and you’ve noticed that your tabs keep crashing, it could be due to one or more of the following reasons:

• Slow or faulty hardware – If there is not enough memory available on your computer system for Firefox to run smoothly without any hiccups, then it will lead to crashes. 
• A temporary network problem – If your Internet connection is slow or if the server that hosts your favorite sites is down temporarily, this can cause some websites to load slowly or not at all — which can make Firefox unstable.
• Malware infection – Malware such as viruses and spyware often affect the stability of web browsers like Firefox. Don’t hesitate to use an antivirus for safe browsing.
• Too many tabs open – The problem is likely caused by a memory leak that occurs when you have too many tabs open at once in Firefox. Not having enough memory available to handle the task can cause Firefox to crash.
