It’s that time of the Firefox release cycle again: we’re at the verge of the 3.1 release, code named Shiretoko. The betas are getting pretty stable and usable for everyday use.

This usually means also that many of our tried and trusted add-ons stop working, because they have not been marked compatible with the latest Firefox version yet.

So for your convenience links to add-ons with incremented maxVersion number in their install manifest.

• livehttpheaders 1.14 updated for Firefox 3.1
  
• openprofilefolder 1.1.7 updated v1.1.6 for Firefox 3.1, see Open Firefox Profile (add-on)

These are not changed in any other way than setting the maxVersion number – but you should’nt trust me and verify for yourself!

So you want to peek under the hood of all those mysterious Firefox 3.x databases? Easy does it: just install SQLite Manager in… Firefox itself (for easy installation visit SQLite Manager on the AMO site).

This add-on can be activated from the Tool menu and opens in a separate window. By default, a shortcut to your profile directory is provided, but there is nothing preventing you from opening other sqlite3 databases when you’re done staring at the places.sqlite database.

On Mac OSX there is lots to explore about your Mail.app settings in your ~/Library/Mail directory, e.g to optimize mail performance. Just be careful that you don’t make any changes on the live database (you work on a back-up copy, right?).

It is easy to get lost if you’re working with many development profiles in FIrefox: what profile is currently running? There is no easy way to find out from the browser.

So… a search on addons.mozilla.org brought up open-profilefolder which was almost what I wanted, except it has not been updated for Firefox 3.0.

So here my version with the following changes:

• installs in Firefox 2.0.x and 3.0.x
• shows the name of the current profile folder in the Tools menu

Update: LiveHTTPheaders 0.14 has been released.

Web browser Firefox is getting ready for a new version 3.0 – to be released soonish. Currently the second beta version has been released for testing.

One of the add-ons (AKA extensions) that I’m using frequently, is LiveHTTPHeaders. This extension has not (yet) been ported for Firefox 3.0.

I made a quick fix, which makes the extension working for me in Firefox 3.0.0b2. I just had to change the compatibility information and the size of the “about” tab in order to fit within its popup window.

As long as there is no official update, and you need livehttpheaders badly, you may want to download and install my patched version: livehttpheaders-0-13-1-patched.xpi. Of course, there is no warranty (you may post bugs in the comments if you like) and you’re using the add-on at your own risk.

Before installing, you should check the XPI’s contents so you are sure you can trust the extension.
Tip: uncompress the XPI and the embedded livehttpheaders.jar file and check a diff against the official 0.13.1 release version.

Update: if you need Firebug, you can install firebug 1.1 beta (Firebug 1.1 is Firebug 1.05 by Joe Hewitt with enhancements and bug fixes by John J. Barton (IBM Almaden) and Max Stepanov (aptana))
