Portable Firefox 1.0 (USB Drive-Friendly)

Portable Firefox is a fully functional package of Firefox optimized for use on a USB key drive. It has some specially-selected optimizations to make it perform faster and extend the life of your USB key as well as a specialized launcher that will allow most of your favorite extensions to work as you switch computers.

Nice look of the Mozilla knowledge base (some things are still beta: the plugin FAQ is still terse, better stick to PluginDoc).
Note to self: After installing Real 8.0, install the Help file by clicking on this link.

Installed Firefox 1.0 today. Only intended to clean my profile, but got carried away. Here are the main lines:

• backup & delete profile folder
• download & install Firefox latest (what is the difference between a trunk and a branch?)
• download extensions (from extensionmirror, Clav’s extensions, Mozilla update , Gorgias’ extensions, Texturizer or Extension Room.) I recommend downloading xpi’s one by one and install them offline, so you can check your profile between each install.
• If your favorite extensions does’nt install on FF 1.0 because the xpi says « 0.10 & no more », try bumping extensions (but extensions featured at extensionmirror are already bumped before mirroring).
• More at extensionsmirror: Usefull Links, mini-guide on how to get things working again WITHOUT creating a whole new profile (originally on Mozillazine forum), (closely) related extensions, The Most Requested Extensions & Tab-related Extensions.
• Before despair, invoque Firefox Help.

• MakeLink (Thru | v2.0 MozillaZine thread) downloaded, installed, tested, happy !
• Need to keep this explaination by rbf (in the TBP thread) in store, could be useful one day…
  

  I’ve solved some problems the « not necessarily best method » way. Normally, when you uninstall an extension, only the .rdf’s pointing to the directory are removed, but the extension still exists. Sometimes items don’t uninstall or disable at all. When that happens, the only way to clean up a profile is:

  1. make a zip backup of your entire profile in case the next steps really hose it up. I zip up my program directory too. You have to do this while the browser is shut down or you will get zip errors on files in use.
  2. use file-explorer to go to the top of the profile tree, and search for « extension name » in the text search entryfield. This should display any .rdf files pointing to the extension.
  3. edit those files and remove the instances of the extension name CLEANLY… get the .... or so you dont make xml errors.
  4. remove the jar directory.
  5. restart FF.

  This doesn’t work for the Tinderbox status icon. I have to leave the directory, else FF never displays. It would be nicer if the extension directories were not the classId, so it is easier to find particular extension dirs. Clav names his with a simply « cards », or « goup » and they are easy to locate.

  This is not a tutorial on writing Firefox extensions because there are already good ones out there on the web (see below). Here I give references to full tutorials, and then provide my own tips about tools and publishing that are not covered in the tutorials.
