TL;DR: Please recommend the “Reset Firefox<\/a>” feature to anyone who complains about odd, persistent performance problems and\/or high memory consumption.<\/strong><\/p>\n

In Ars Technica’s article about the Firefox 19 release<\/a>, carbon fibre made a comment complaining about Firefox’s performance.<\/p>\n

Firefox still doesn’t fix memory issues and smoothness, at least on my experience. It’s constant random jerks and extreme mem usage, until restarted. I use chrome but I have been wanting to switch FF for awhile, but I can’t, as long as they fix these issues, long standing issues since ver. 4.<\/p><\/blockquote>\n

There were four notable responses.<\/p>\n

They are losing market share by not fixing the memory issues. Even on my 8GB SSD i5 system I have to restart it when it reaches over 1 GB because it starts to slow down A LOT. And it get over 1 GB very fast for someone who constantly open\/close tabs like me (even in safe mode).<\/p>\n

I was an avid FF user until I saw myself installing an add-on to restart FF when it reaches X MB of memory usage.<\/strong> Today I use Opera for most of my browsing but I some sites does not work properly with Opera and some extensions only exist on FF.<\/p>\n

Shame.<\/p><\/blockquote>\n

Do you have extensions installed? Maybe one of them is causing it.<\/p><\/blockquote>\n

every benchmark I saw, firefox uses less memory than everybody else, I really don’t get why people complain about it?<\/p><\/blockquote>\n

You might have problems with your profile. Visit about:support, and click on the “Reset Firefox” button in the top right corner. It’ll generated a new profile that preserves much of your browsing history, though it will disable any add-ons you have. (It’ll give you details about exactly what it preserves and discards before doing so, so you can cancel it if you change your mind.) This step fixes a lot of performance problems like the ones you describe.<\/p><\/blockquote>\n
