I recognized a slowdown of Firefox during surfing. After a programme restart all was fine again but slowdown occurred again.
This is what I did to resolve the problem.
- Inactivation of all addons not in much use
- Inactivation of all greasmonkey scripts not in much use
- Changing preferences of "Link Alert": inactive status for links and images
- Changing Firefox settings in "about:config":
-
extensions.s3downbar.function.useAnimation;false (this can also be changed through the preference page of Download Manager (S3))
- browser.tabs.animate;false
- browser.fullscreen.animate;false
- browser.download.animateNotifications;false
- toolkit.scrollbox.smoothScroll;false
- extensions.treestyletab.tabbar.scroll.smooth;false
