SeaMonkey overview

SeaMonkey is a Web browser that shares much of the same base code as the popular Firefox Web browser. It also contains an advanced e-mail and newsgroup client, IRC chat client, and HTML editor.

The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as "Mozilla Application Suite". Whereas the main focus of the Mozilla Foundation is on Mozilla Firefox and Mozilla Thunderbird, our group of dedicated volunteers works to ensure that you can have "everything but the kitchen sink" and have it stable enough for corporate use.

Keeps crashing within 20 seconds. Had to uninstall. Shame as I was willing to give it another go after reading good reviews. Will look out for updates to solve this in the near future.

Under Mac OS Catalina on my iMac the app refuses to load due to security issues. I'll have to check in from time to time to see if the developer has updated it. The good news is there are so many other browsers out there.

Just uninstalled Seamonkey because it has become unresponsive. Will try to download a fresh copy and hope it works because I have depended on Seamonkey for years.

Less space, other tools doing similar job & more used to them. No reflection on SeaMonkey capabilities or ease-of-use.

SeaMonkey is the best browser I've used. It lets me organize my browsing, sort bookmarks and track data while I investigate issues on the net. I don't need separate applications to work with my email and browsing, SeaMonkey does it all. My only issue is that it can sometimes be slowed down by the spinning wheel, requiring me to press the <Esc> key multiple times to exit from the blockage.

The first thing this software did, was alerting that the 2.49.2 did not work on my machine, so I tried the 2.49.1 instead. When I tried myself at the add-ons, there was no ad blocker available, so I had to throw this thing out of my system.

This version of SeaMonkey killed my previous Mac to the point I had to buy a new machine. Even now the Mac can browse using his version but as soon as I try to access email it crashes. Its a terrible shame as S/M is my preferred browser.

Is the current version 2.48 or is it 2.46? The developer website says the current release is 2.46.

Despite lagging news on the developer site and blog, this appears to be the Final version of 2.4.8, versus it being another beta release.

tangled mess of many unfinished versions of the suite on Mozilla's servers - no evidence of safety critical outdated versions on Seamonkeys website . Is because seamonkey still legitimate?
