As has been pointed out above, these problems are triggered in a variety of situations. But for me, the most common culprits have been unwanted scripts running in the background. I've found that running "NoScript Security Suite" helps immensely. "NoScript Security Suite" can be found here:
https://addons.mozilla.org/en-US/firefox/addon/noscript/ After activating NoScript, you'll need to allow certain scripts to run for some sites to function properly. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/990997 Title: Firefox interface is horribly laggy in a variety of situations, with delayed scrolling and typing Status in Mozilla Firefox: New Status in firefox package in Ubuntu: Triaged Bug description: Typing is extremely slow in typing in multiline fields. This happens with the text field on twitter, google+, blogger. Usually there's a big delay between typing and charachters to appear and cpu works a lot. Everything works fine with other browsers like chrome or opera. Disabling Javascript doesn't solve the issue even because withut js it's impossibile to load text fields that make a large use of it. My pc is equipped with a nvidia 8400gs m video chip. Let me know if more informations are needed.
