Here are some steps follow it to resolve your issue:
1. Uninstall the latest buggy Skype plug-in:
are experiencing that Facebook, GMail or Google Reader are really
crawling and you’ve recently updated Skype to version 4.1 and installed
the Skype plug-in for Firefox, try uninstalling the Skype plug-in, but
leave the main Skype program installed. That should help. Hopefully,
Skype will update this plug-in soon because, reading the tweets on slow firefox,
it’s certainly responsible for driving a number of people away to other browsers, particularly Chrome.
2. Check how much memory Firefox is using:
Windows Task Manager with Ctrl-Alt-Del in Windows XP or Crtl-Alt-Esc in
Vista and go to the Processes tab. Look for the process called
firefox.exe and check the memory usage: for example, 230,000K is 230MB.
Try cutting back on the number of tabs you have open and uninstall any
plug-ins you really don’t need and see if this brings down memory
usage. If you’re anything like me, you’ll have installed plug-ins which
seemed a good idea at the time but which you now rarely, if ever use.
3. Do some maintenance:
Use a program like CCleaner
(for Windows) or BleachBit
(for Windows or Linux) to clear your browser temporary files, internet cache and browser history regularly.
4. Modify the Firefox config file:
tweaks which involve modifying the config file for Firefox. I’d heard
some of these a while ago on the Mike Tech Show podcast, also at Life Rocks 2.0
. It’s not difficult to edit the config file. Just type about:config
in the Firefox address bar and press enter. Then type network.http
in the filter field. This will filter the list down to only those with
network.http in the name. Now make the following changes:
- Double click on ‘network.http.pipelining’ and set the value to true (double clicking toggles the value between true and false).
- Double click on network.http.pipelining.maxrequests’ and in the dialog box enter a value higher than the default value 4. According to Mozillazine, the maximum you can use is 8.
- Double click on ‘network.http.proxy.pipelining’ and set the value to true.
- Again in the filter field enter ‘browser.sessionstore.interval‘
(without the quotes), double click on the entry and change the value
from 10000 (10 secs) to 120000 (2 minutes). This adjusts how frequently
Firefox creates session restore save points. Firefox will now take a
snapshot of your browsing session every 2 minutes instead of every 10
- Right click on the page and select New->Integer. Enter the name nglayout.initialpaint.delay and then click ok. Set the integer value of this to 0 and click ok.

5. Disable Firebug:
If you’re using Firebug, it can slow Firefox to a crawl
6. Optimize Firefox’s SQL database:
Firefox uses SQLite databases to store lots of its settings. With time, the databases grow and Firefox slows down. Use either Vacuum Places Improved
, a Firefox add-on, or SpeedyFox
a stand-alone app to compact these databases without losing any data. I
prefer SpeedyFox as I like to keep the number of Firefox add-ons to a
minimum. Only works in Windows at the moment though. Thanks again to Life Rocks 2.0
for this tip. I also use the portable version which doesn’t modify the Windows registry.
