Since the new update, when I start Firefox, there are long disk reads and writes daily that interfere with browsing & last 10-15 mins - what's with this?

While these disk reads and writes are going on, Norton displays "High disk usage - Firefox". Under "Details", it identifies the process ID's as 10536 or 11112. The reads run from 335 MB up to 29165 MB and the writes from 293 MB to 10881 MB. This is happening daily when I use Firefox for the first time. I do stock trading and start the day with some disk-intensive charting applications, so these Firefox processes really slow down my access to information I need in real time. At first, I thought these were additional updates connected with the new version, but they've been happening daily for about 2 weeks now.

Thank you for elaborating. Currently the Nightly version of Firefox update more often then the stable releases of Firefox. It is on a rapid release cycle.

Do you happen to have the version number of nightly when this started happening? This can help narrow down what edits to look through :-)

Also the Telementary data sent on the browsers can help improve the performance. There are also automated tests done to check performance of different platforms.

If you are interested in providing a website example this could help create a bug. With the websites, there are have these tools to test the performance of the profile as well: This will test the javascript engine on desktop: https://developer.mozilla.org/en-US/d.../Reporting_a_Performance_Problem and for android local host builds these test can be reproduced here: https://developer.mozilla.org/en-US/d.../Profiling_with_the_Built-in_Profiler#Profiling_Firefox_mobile

There is also DTrace that can help optimize development on javascript pages https://wiki.mozilla.org/Performance/Optimizing_JavaScript_with_DTrace#Ti...

We look forward to your reply
