In a little more detail...

I am a software developer and have been playing with Mozilla software since 2003. I absolutely love the way it can be extended to do just about anything and I make use of that. So I create extensions and occasionally fix issues in the Mozilla source code (mostly I just try to file good bug reports however). After working on several applications based on Mozilla's XULRunner my main job these days is developing Adblock Plus.

Add-ons I've created

My Reviews

Cycle Collector Analyzer, about:ccdump

Nice helper for memory leak hunting Rated 5 out of 5 stars

This extension got a lot better in the current version, getting an overview is easier and it can handle large amounts of data without hanging up the browser. Also, the JSON-based log is easier to read and also easier to process with scripts than the old format. There are some minor issues left which will hopefully be resolved in future releases:

* Pagination isn't the best way to display large amounts of data. Something like SlickGrid with its virtual rendering would have been nicer.
* The display of edges and owners is still suboptimal - when you expand the list you get no useful information at all. Typically, when you expand the individual item the additional information isn't useful either. Only after expanding the "to" property you get something useful. Giving a proper overview immediately after expanding edges shouldn't be impossible.
* A way to select a particular subtree would be nice - e.g. all direct and indirect owners of an entry and all direct and indirect edges.
* Seeing the memory use of the objects would be nice as well but that information unfortunately isn't exposed by Gecko (and probably cannot be exposed).
* Saving a large log (e.g. when "Trace all" is enabled) hangs up the browser. Fixing this is non-trivial however.

This review is for a previous version of the add-on (0.4.1).  This user has a previous review of this add-on.

Cycle Collector Analyzer, about:ccdump

Nice extension but weaknesses on the analysis side Rated 4 out of 5 stars

This extension has the potential to make memory leak hunting a lot simpler. It isn't quite there but the start is promising. Main problem is that you will typically get a very large set of data (thousands of objects) and are mostly left on your own exploring the structure of the graph. Issues:

* Displaying the roots is only possible when searching, not from the graph view however.
* The graph view cannot handle a large number of objects, expanding the graph with 30k objects takes a minute. What's even worse, expanding a single entry after that takes lots of time as well - it seems that the entire tree is being rebuilt.
* Generally, the tabular view as presented by the search seems to be superior to the default tree view - all the necessary information is presented at one glance without having to expand everything.
* The search is case-sensitive which is unexpected.
* The edges and owners display is suboptimal, it requires expanding two nodes to learn the name of an edge - it should be visible immediately when the edges are expanded.
* Flexible filtering options are required. In addition to the existing search and roots display it would be nice to see which objects are being held by a particular object (via direct or indirect references) as well as the actual chain between an object and its root.

HttpFox

Good LiveHttpHeaders replacement Rated 5 out of 5 stars

A really nice tool. I have been a LiveHttpHeaders user for a long time but this extension really organizes the information much better. It gives you a nice overview of all HTTP requests being made and you can select one for closer inspection - headers, cookies, POST data, response text, whatever you like. Some issues, nothing major:

* Logging should really start automatically when the HttpFox panel is opened first time (issue 38)
* The value in Received column makes very little sense (issue 21)
* There is no keyboard shortcut to open HttpFox panel (issue 29)
* Response text comes from browser cache, this isn't the most reliable way of getting it (issue 6)

I would also very much like it if it could somehow display headers in Page Info dialog, that's the only reason I keep LiveHttpHeaders installed (I realize that LiveHttpHeaders has to watch requests in background constantly for that). But I must say, this extension is very good already.

This review is for a previous version of the add-on (0.8.4). 

Covert Adblock Plus

Rated 1 out of 5 stars

First I thought that this extension was hiding ads instead of blocking them, something that is absolutely pointless as explained in https://www.mozdev.org/bugs/show_bug.cgi?id=18397#c1. I checked - and apparently that's not it. This extension is simply Adblock Plus 1.1 development build 2009050712, the only changes are extension ID/name/version/author name. So, what's the point?

"outtatime", I have no problem with you rolling your own - but please don't post it with a misleading description. Also, did you look at the license of the code you are using? You cannot simply apply GPL license to MPL-licensed code.

This review is for a previous version of the add-on (1.1). 

Correct Identity

Does just what it promises Rated 5 out of 5 stars

This is a great extension for people like me who dump all their incoming mail into one account but still want to reply from the correct address. When you reply to a mail Correct Identity will automatically select your identity the mail was addressed to. The options also provide you with a way to set the default identity for each account or override selected identity depending on sender addresses - but that is almost unnecessary. This extension will do its job reliably and without ever bothering you with configuration. Very recommendable.

This review is for a previous version of the add-on (1.3.1).
