I used to love this Add-on and found it indispensable. I used it for many months to categorize a lot of temporary research I do, quickly and easily. I like the user friendliness of the UI and simple to use features.

But I had to stop using it when I discovered that it was solely responsible in slowing down my browser. Every time I would open a new blank browser page (not a new tab) it would take up to 14 seconds to open. OUCH! This is on a 24" iMac 2.8GHz Dual Core;. no slouch of a machine. (I used a helpful add-on call XUL Profiler, found on this site).

I contacted the developer and I was told that TMT is not designed to handle a lot of bookmarks. (Yes I have a few hundred in TMT). I explained that FF 3.6.13 has no trouble opening a new page in a split second even with few thousand bookmarks I have.

This tells me that TMT coding is very poor from a speed perspective but the developer expressed no interested in fixing this issue. Too bad. I really like this add-on.

Nice simple way to get all those tabs under control. Essentially gives a user interface to some of the built in features of FF so it takes fewer steps to store those tabs, with a convenient way to access them.

There are a couple of issues:
1. does not play nice with MultirowBookmarksToolbar (MBT). Changing the # of rows affects the way that TMT re-sizes itself vertically where the two areas overlap, e.g., when size of TMT is set larger. Not sure if the problem is TMT's or MBT's.

2. Contextual menu does not show up if FoxTabs is installed. Again not sure if this is TMT's issue or FoxTabs.

3. Close Window when last Tab added to FF does not work.

I am using FF 3.5.3 on OS X 10.4.11

Otherwise, a very decent tool.

This review is for a previous version of the add-on (1.0.2).
