Not Responding error Firefox Quantum

We have been testing out Firefox Quantum browser in these days. According to Firefox, it is 2x faster and consumes thirty percent less memory than Chrome. Yes, it is true, and in that case, it can beat Google Chrome easily.

How Does It Work?

In brief, Firefox uses RUST programming language, a new CSS engine. They also added some tricks to loads all the essential elements first and prioritizing the foreground tabs for proper memory management.

You can see the comparison between Google Chrome and Firefox Quantum speeds in Top 10 sites.

 

As Nick Nguyen, vice president of Firefox products said, Quantum will work great in the 32-bit processor with less than 4 gigabytes of ram.
Therefore, we tested in our 32-bit machine with 3 GB of ram running on Windows 10. It feels light and fast. Unfortunately, sometimes it causes lags as Firefox older versions and also asks to disable some popular extensions.
