Re: [FireFox] FF 18 sluggish,.........
said by quatrix:Same here. Accessing the bookmarks menu causes the computer to lag. The only add-on installed was QuickJava and disabling it didn't matter.
There's definitely something wrong. The bookmark menus are very laggy after updating to 18. Task Manager shows Firefox using 10% of my i7-2600K when just moving around the bookmark folders.
I reverted back to v17.0.1 and things are working fine again--no lag. I have over 2,000 bookmarks.
edit: v18 was clean install, not upgrade. Favicons and site_icons always set to false in about:config
