Firefox very slow [closed]

I am running Firefox 23.0 on Ubuntu 13.04 (64-bit) and it is a real pain at the best of times.

It takes around 45 seconds to have a usable window after I click on Firefox in the launcher: 15-20 seconds for a window to show, and then 25-30 seconds of a blank window before it is usable.

Many web-pages that I use regularly cause Firefox to freeze up for around 10-20 seconds before it is usable again.

I first thought there was just a bug in Firefox 21/22, so I waited a few versions before speaking up. I installed a clean Ubuntu 13.04 a month or two ago.

In comparison, LibreOffice and Gimp are both usable within 10 seconds after I click on them. The problem does not, therefore, seem to be hardware-related.

I would appreciate any help! Just please don't tell me to switch to Chrome/ium. Firefox worked perfectly on Ubuntu 12.10 before I clean-installed Ubuntu 13.04.

Solution 1:

Bitten by the same problem. To make a long story short, open tools->add-ons manager, and disable Ubuntu Firefox Modifications. Back to fast browsing.

Solution 2:

try this, type "about:config" on address bar> enter search and change/toggle by right clicking on item as-

• network.http.pipelining > Make it True

• network.http.pipelining.maxrequests > Make it higher (i set 34)

• network.http.proxy.pipelining > Make it True

• network.dns.disableIPv6 > Make it True

my firefox on netook system got really normal as on windows

Solution 3:

Ok, it appears the PrivacyChoice.org TrackerBlock plugin seems to be the culprit.

The first thing I did when installing was to protect myself from the NSA and advertisers. But, now when I started Firefox in Safe Mode, it was super-fast, as one would expect from a 64-bit system, even if my hardware can be slow sometimes.

I use other blocking plugins now instead. Be warned!
