What is Chrome


My system slows down and eventually I get an unresponsive script with a name that starts with Chrome. When I do a search I find I have 7 chrome.manifest files, 8 chrome folders (1 is a shortcut), one chrome.rdf file and two userchrome-example.css files. What is chrome? Why do I have so many? What causes the slowdowns?

Additional System Details

This happened

Every time Firefox opened

This started when...

Around the first of August

We'll need the full error message to provide specific help.

Creating a new profile may cause the error to go away. You can find directions on creating a new profile https://support.mozilla.com/en-US/kb/Managing+profiles#Creating_a_profile

If that helps then use http://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile to get back your bookmarks and other personal settings.

The word chrome is a generic term "The basic structural elements used in a graphical user interface, such as window frames and scroll bars, as opposed to the content." dfn 2 of http://en.wiktionary.org/wiki/chrome

The chrome files you have found are needed for Firefox to function correctly. Please do not remove them.

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
