In a little more detail...

I finally did it. I switched to Firefox when I switched computers. I just wish they could create all programs in the SeaMonkey Suite as separate programs, but make them optional in the SeaMonkey install, like the old Netscape. Support for Gecko is Gecko is greatly needed, including in the Mozilla Project. If you make the browsers different so that add-ons are incompatible, then Gecko isn't Gecko.

My Reviews


Rated 3 out of 5 stars

I really enjoyed this add-on with SeaMonkey. After the latest update to the Gecko engine, this no longer works with newer versions of Firefox, SeaMonkey, etc. Please do the best you can do update this. We all appreciate your work. -Thanks

Firefox Sync for Firefox 3.5/3.6

What support section? I can install it on Seamonkey, but it won't work.

This review is for a previous version of the add-on (1.7). 

Custom Buttons

Rated 1 out of 5 stars

How about premade buttons for common actions. What about a line for the URL of the action you want to perform. This could be as simple as the path to an executable or http or chrome path. This is a programmers addon. I simply wanted to add my address book to my email toolbar in Seamonkey. When I tried to log in to the forum, it asks for my username. I thought they had unified signin for all Mozilla sites. I can't read the captcha. Not all this is due to the addon, but it's just frustration upon frustration.

100 Search Engines for Firefox

Rated 1 out of 5 stars

The link to install for SeaMonkey says, "Sorry, you need a Mozilla-based browser (such as Firefox) to install a search plugin." It should say this is not compatible or needs the Firefox sidebar addon.

Where is the version for Seamonkey. It keeps directing me to this page and claims it intalls, but the version for seamonkey is missing. If I type in, it redirects to

I should have read the reviews. I'm running Thunderbird 3.1.9, so it won't install. Is this extension on hiatus, or has it been dropped?
I'm giving it one star because it won't work. You need updated Thunderbird versions for newer extensions like Lightning to halfway work.

This addon works so much better with Seamonkey. There is no integration between Thunderbird and Sunbird with this addon. It also ties up a tremendous amount of resources. I constantly get popups about calendar.js. I must disable the addon so I can use Thunderbird. Understand this is a beta version.

Once the excessive resource use is overcome, I suppose I could manually set Lightning and Sunbird to use the same calendar which should work if it is a local calendar and I do not attempt to open the same event with Lighting in Thunderbird and in Sunbird.

I wish they never split the development of the independent programs from the suite. Support for too many variations means someone gets left out.

I used this with Seamonkey and it worked great. I finally switched to Firefox; it worked, but the presets seemed unavailable. Now, please, we need an update for Firefox 4. I don't know why the Mozilla project never included real cookie control, but we appreciate this add-on. I would donate if I could. THANKS

This will not install for SeaMonkey/2.0.10. Support is nonexistent. The email address is no longer valid and a question posted at the forum site as of today [2010-11-4] is 322 days old and has yet to be answered.

Classic Default

Rated 2 out of 5 stars

The parts that work look great. I think the problem with the Home icon is that it is set too small. It shows correctly with icons and text, but is smaller than the other icons.

Any plan to update this theme? Is this project dead?
