Ubuntu Firefox sucks?

Firefox on Ubuntu seems to have slower performance than on other OSes.

Symptoms:
- slow on page with flash, or hang when scroll fast, or unbearable slow (invoking CD-ROM) when type in address bar, especially on "backspace" key, ...

AFAIK, there are 3 major causes:
- FF's database SQLite becomes big and defragmented
- weak graphic card (usually on laptop)
- IPv6 is higher priority than IPv4 in FF by default.

Recommended work-arounds:
- change Visual Effects to "None"
- disable IPv6 in "about:config"
- clean up SQLite unused entries: first, install sqlite3 client
sudo apt-get install sqlite3
then enter these commands
find ~/.mozilla -type f -name "*.sqlite" -exec sqlite3 ‘{}’ VACUUM \;
find ~/.mozilla -type f -name "*.sqlite" -exec sqlite3 ‘{}’ REINDEX \;
or use these commands instead
for i in ~/.mozilla/firefox*/*/*.sqlite; do sqlite3 $i vacuum; done;

Alternative browsers:

+ Google Chrome for Linux
( http://www.google.com/chrome?platform=linux )

+ Konqueror
( sudo apt-get install konqueror )

+ Chromium (Ubuntu)

Pidgin Y!M connection

Sometimes the Y!M pager server is down for maintenance. Therefore Pidgin clients encounter connection problem.

You may fix it simply by changing the pager server settings:
(Account -> Manage -> -> [Y!M account] -> Modify -> Advance)

default: scs.msg.yahoo.com

change to: cn.scs.msg.yahoo.com (66.163.181.166)

(
or: cs101.msg.cnb.yahoo.com (202.165.100.160)
)

P.S: Kopete or Empathy clients issue can be fixed in a similar way, too.
