Comparing SeaMonkey to just another web browser is unfair to the other web browser. SeaMonkey isn't just a web browser. Netscape used to offer a full suite of tools, I never found another web browser which offered as much. SeaMonkey took over where Netscape left off, and they have kept the project active. Nothing on the alternative list is really an alternative at all.

If the cosmetics aren't what you like try some skins. Or make one to suit you.

Seamonkey(SM) is almost identical to firefox in the underlying technology, the only difference is the UI, which has not changed like Firefox which is trying to play catchup with Chromium. Some firefox features are missing from SM.

SM is suited for people who want a consistent interface which they are familiar with. Also SM requires less resources compared to firefox.

Might be a winner if you are into IRC .. they have shortcuts to it.. though I hear IRC is not very secure. From the start, I am finding it awkward to use.. it's the little things, like not having the + icon to click to make a new tab, difficulty in finding Settings. There is a Beta version out. I'm new with 2.53.14 September 29, 2022, and I will give it more time. There are some setting options I like better than chrome.. the cookie handling seems easier.

I like Seamonkey because they are a lot of good functionalities (like composer) that we not found in the actual Firefox or Chrome.

(Sorry for my bad English)

Sadly, it's fallen badly behind the times; the Internet moves fast, and SeaMonkey doesn't. My family has been using SeaMonkey for many years on Windows, up through and including Windows 10. It was a solid product, and offers the integrated suite of browser, email, etc. for those who want that. Unfortunately at this point it seems to have a very limited community supporting it, having gone for over a year without updates (late July 2018 to early September 2019).

The current version is based on Firefox ESR 52 and more and more websites are considering it an obsolete browser, making it hard to recommend. For example, one of our banking sites will no longer permit logging in using SM. We also find various minor glitches, such as the inability to look through all of the product photos in pop-ups on some shopping websites. These aggravations are individually small but getting ever more numerous.

The home page reports plans to update to the ESR 60 code base, but the current FF ESR is 68, so SM will still be lagging considerably. This has pushed us to migrate to Firefox + Thunderbird, in place of SM, in order to have "modern" Internet applications.

I give it 4.5 stars, historically, but only 3 stars for use today.

In my opinion this is one of the best web browsers out there. There are a couple of minor issues.

  1. It segfaults (crashes) on OpenBSD but not on Linux.
  2. Some modern javascript does not work (e.g. camera)
