Ubuntu: Howto drastically speed up Firefox
Make firefox store its cache in the /tmp directory — which when we have moved it to a tmpfs according to this wiki is *fast*.
- Firefox 3.x uses a sqlite db that creates many write accesses, so this can reduce it:
- In Firefox go to (type as url) “about:config”, right click, add new string „browser.cache.disk.parent_directory“ with value “/tmp/firefox”
- In Firefox change options/security/ and disable phishing if you dare. – Your firefox will run even faster then but won’t warn you about phishing any more so take care!
Alternatively, to speed up Firefox further, enter “about:config” (without the quotes) as an url in Firefox, then change the following settings:
// disable disk and offline cache
set browser.cache.disk.enabled: false
set browser.cache.disk.capacity: 0
set browser.cache.offline.enable: false
set browser.cache.offline.capacity: 0
// just as a precaution
add browser.cache.disk.parent_directory: /tmp
// apparently safebrowsing slows things down – disable at your own risk!
set browser.safebrowsing.malware.enabled: false
set browser.safebrowsing.enabled: false
set network.prefetch-next: false
// don’t show suggestions in the search bar
browser.search.suggest.enabled: false
// don’t spellcheck as I type
layout.spellcheckDefault: 0
