Split the tab. Keep the proportions.
Start from a layout or split any pane in two. Drag the dividers until each site has the room it needs; the proportions are saved when you let go.
Flincth for Firefox
Flincth for Firefox splits a single tab into panes, puts a different site in each one, and saves the arrangement as a workspace. Switch workspaces with a click or a shortcut.

Illustrative preview, not a screenshot of the extension. Sites shown are placeholders.
Stop rebuilding the same four tabs side by side. Arrange them once, then switch.
Start from a layout or split any pane in two. Drag the dividers until each site has the room it needs; the proportions are saved when you let go.
Each pane shows its site in whichever way that site allows.
Inside the tab, for most sitesA real window lined up with the pane, signed in as usualA card that opens the site in a normal tabClick a workspace or press the shortcut you gave it. Layout and sites change together.
Recent workspaces stay loaded while you are away, so a half-typed reply or a paused video is still there when you switch back.
No access to any site when you install it. Firefox asks for one site at a time, only when you put that site in a pane, and you can revoke it from the settings page. No analytics, no account, no server.
YOUR WORKSPACES STAY IN YOUR BROWSER. Read the privacy policyThree steps, and the arrangement is yours to keep.
Open Flincth from the toolbar, name a workspace and pick a layout.
Type an address or pick one of your open tabs. Firefox asks permission for that one site.
Click a workspace, or press its shortcut. Everything you left open is where you left it.
Not yet. A Firefox version is planned. Its privacy and permission design carries over from the Chrome version unchanged, and it will need Firefox 128 or later. This page will link to Firefox Add-ons when it is ready.
No. The extension is a separate product that lives inside your browser. The Mac app arranges app windows across your displays; the extension arranges websites inside one tab. Each works without the other.
Some sites refuse to be shown inside another page, and some keep you signed in with storage an embedded view cannot reach. For those, a pane can become a real browser window lined up with the pane, so the site behaves exactly as it does in a normal tab. Because it is a real window, it also appears in your window switcher and in screenshots.
Flincth requests no site access when you install it. To show a site inside a pane it removes the one response header that blocks this, only for that site and only inside Flincth’s own tab. If you decline, the pane offers an attached window instead, which needs no permission at all.
No. It never reads cookies, never looks at page content and never adds code to a page. Your workspaces and the addresses in them are stored in Firefox on your own device, and the extension makes no network requests of its own.
Give each workspace its own shortcut when you create or edit it; those work while the Flincth tab is focused. Four more reach a workspace from anywhere in Firefox, even while you are typing in a pane. Choose which workspace each one opens in Flincth’s settings, and set their keys under Manage Extension Shortcuts in about:addons.
