If you can not hear any sound when playing flash video in Firefox, It’s probably because that you hasn’t installed the package ‘libflashsupport’. To solve it, just install that package and restart Firefox.

For Fedora, you may use the command

# yum install libflashsupport

I am migrating to `Google bookmarks’, but the button on Google Toolbar always says `Downloading bookmarks …’. But in Windows, Google Toolbar in Firefox can import, download, add bookmarks normally. What’s different in Linux?

After googling for some time, I realize that it is due to lack of the library `libstdc++.so.5′. This is one of the old versions of C++ libraries, most of current Linux distributions do not install this library by default. The method to solve ‘Downloading bookmarks’ problem is:

1. Install the package that contains libstdc++.so.5. For Fedora 8:

# yum install compat-libstdc++-33

For Ubuntu:

# sudo apt-get install libstdc++5

For other distributions, you should install the corresponding packages.

2. Exit Firefox, restart Firefox, re-install Google Toolbar. This is very important, or else the problem will not be solved!

3. Restart Firefox. Now you can see all your bookmarks in your Google toolbar!
