Which one is for you
Pick Floorp if
- Fits if you like Firefox but want tabs grouped by task
- Works for anyone who wants up to four pages side by side in one window
Look elsewhere if
- Not for you if you want it on your phone: there's no stable mobile version and iOS is only in TestFlight
- Watch out: it's a Firefox derivative, so it follows Firefox's engine and release timing
- Watch out: downloading it means agreeing to the project's Terms of Service
Pick SeaMonkey if
- Fits if you want browser, mail and IRC in one desktop program
- Makes sense if you read newsgroups or edit HTML pages by hand
Look elsewhere if
- Skip it if you want a phone version, as the site offers no iOS or Android edition
- Not for you if you use an Apple silicon Mac, since only an x64 macOS build is listed
- Watch out: the current release listed is 2.53.24, built on the Gecko engine
- Too heavy if you only want to browse, since mail, chat and editor come along

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
