Google toolbar v5 issue on Ubuntu 7.10

I installed the Google toolbar v5 for firefox on ubuntu 7.10. It doesn't function well, firefox easily freezes and the bookmark doesn't function, hanging with a message of loading bookmarks. After some search online, this problem is solved by the following steps:
1. Uninstall the Google toolbar v5 first, and restart firefox to make it take effective.
2. Install libstd++5 and its dependent packages.
3. Install the Google toolbar v5 again.

After this, everything works fine.

Adobe flash player not working for Ubuntu 7.10

Ubuntu question #19584: “Adobe flash player not working”

Below is a quote from the link:

"This is not your fault. This is a very recent bug, caused by Adobe's update of Flash 9.0 update 3 (9.0.115.0) codename 'Moviestar' on December 4th.

http://www.adobe.com/aboutadobe/pressroom/pressreleases/200712/120407adobemoviestar.html

This caused Ubuntu to not install the flash plugin, detecting a change in the flash plugin installer file (via MD5 checksums). See bug 173890. This bug has been fixed in the next release of Ubuntu (Hardy 8.04) and it should soon come as an update to Ubuntu 7.10.

If you want an immediate fix, do the following.

Using Synaptic Package Manager, remove the package flashplugin-nonfree. For more information on how to do this, see the Ubuntu documentation here: https://help.ubuntu.com/7.10/add-applications/C/advanced.html#synaptic

Alternatively, you can run this command in the Terminal (Applications -> Accessories -> Terminal): sudo apt-get remove flashplugin-nonfree

Then just download this package (32-bit only) and install it (it is identical to the current package in the next release of Ubuntu, Hardy 8.04): http://launchpadlibrarian.net/10761023/flashplugin-nonfree_9.0.115.0ubuntu2_i386.deb

If you have 64-bit Ubuntu (not likely or recommended for a person new to Ubuntu), you currently need to build a binary package from this source package: http://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/9.0.11"
