mozilla firefox not responding every few seconds

Ideally, from a stability and security point of view, you'd separate each tab, plugin and the browser UI individually. This is probably one of the main reasons why Mozilla launched the multi-process architecture with one content process initially and increased it to (just) four in recent stable versions of the web browser. Mozilla ran some memory benchmarks recently and found out that multi-process Firefox will use between 10% to 20% more memory initially with one content process enabled, and about double the memory with 8 content processes. Please note that it will use more memory when you increase the number of content processes in multi-process Firefox, and less memory if you reduce the number. Easiest way to do that is Shift-F2, type restart, hit enter.įirefox will use the selected number of content process after the restart. The default value is 1, indicating that one content process is used. Double-click on it and change its value.Confirm you will be careful if a warning appears.

Type about:config in Firefox's address bar and hit enter.It is rather easy to change the number of content processes.
