Dist Switch

Switched to CentOS 6 as my primary Linux OS. Fedora is getting the boot after many, many, years of use. Fedora 15 just has too many things that are wrong with it. In all fairness, some of the issues are with the path Gnome and Linux has taken in general. It was a good run.

Google Toolbar Disabled by Firefox 5
by dervish on Jun.27, 2011, under Linux, Windows
How to re-enable the Google Toolbar in Firefox 5.
Solution: Change maxVersion in the install.rdf file to 5.*. Do a search if your not sure where the file is located.
Linux:
– Edit ~user/.mozilla/firefox/mhznvz4j.default/extensions/\{3112ca9c-de6d-4884-a869-9855de68056c\}/install.rdf
– Change <em:maxVersion>4.*</em:maxVersion> to <em:maxVersion>5.*</em:maxVersion> and save.
– Start Firefox. Toolbar should start normally.
Windows:
The same ./extensions/\{3112ca9c-de6d-4884-a869-9855de68056c\}/install.rdf file can be edited in Windows to restore the Google Toolbar.
Or:
about:config
nightly.disableCheckCompatibility=false
extensions.checkCompatibility=false
