Ardia 0.2.45: Closing the last window now leaves it waiting by the Dock.

Watch

New

• Ardia runs on Chromium 157. The engine moves up from 156 to 157.0.8103.38, with Helium 0.21.1’s privacy patches on top, and brings Chrome 157’s security fixes. Your profiles, tabs, passwords, cookies, extensions and uBlock Origin filters carry over as they are.
• Profiles load when you open them. At launch Ardia starts only the profiles its windows show; the rest, and their extensions, start the first time you switch to them. With eight profiles, launch memory drops from about 1.5 GB to 390 MB, and the first switch to a profile that hasn’t started yet takes about two seconds. Turn it off in Settings › Advanced › Performance › “Load profiles when opened”. Thanks, @Neved4.
• Web apps show their unread count on their tab. Pinned tabs, Top Apps and ordinary tabs pick it up from the page title, the Badging API or a dot on the favicon.
• WebKit pages block ads and trackers. Pages opened in WebKit, streaming sites included, now use uBlock Origin Lite’s lists and follow the same switches as the rest of Ardia: blocking on or off, the lists you picked and the sites you trust. Site Controls shows how many requests it blocked.
• Links from pinned tabs and Top Apps open in a Peek. A link to another site opens over the app instead of in a new tab, with Gmail, Slack and Outlook redirect wrappers unwrapped, as in Arc. Settings › Tabs › “Open new-tab links in” picks New tab, Peek or Little Ardia, and inside Little Ardia new-tab links now stay in Little Ardia by default.
• Report a Problem, one sheet for everything. Help › Report a Problem… (⌥⇧⌘I) takes bugs, slowness and ideas, with an optional recording of Ardia’s window that never shows page contents, a short engine trace for slowness, and a preview of exactly what is sent.
• Settings › Privacy shows how you appear to us. An anonymous name and avatar stand in for your install’s random ID, with Reset My Anonymous ID to start fresh. Under “Kept on this Mac”, View My Data saves the last 7 days of what Ardia logged to your Downloads folder; it leaves your Mac only while sharing is on or when you attach it to a report.
• Live folder tabs go back to their item. A tab opened from a live folder keeps the item’s page as its home, like a tab in a pinned group, so Back to Pinned URL takes you back to it. Thanks, @TechSupportz.
• The page frame goes down to edge to edge. A slider in Settings › Appearance › Page Frame and in onboarding.
• Drop things where you are. Files, links and text dropped on the New Tab page open in that tab, from the Downloads popover too, and a .crx dropped anywhere in a window asks to install it.
• Bookmarks can hide. Turning off “Show bookmarks” in Settings › General hides the bookmark button, the bar, the Bookmarks menu and its commands, and puts Copy URL where the star was. Your bookmarks stay.
• Organize tabs and groups from the command line. ardia tabs and ardia groups list every window, space, group and tab as JSON, and open, move, group, nest, rename, recolour, pin, mute, sleep or close them, by name or ID, without changing the tab you’re on. ardia apply runs a batch in one go, so you or an agent can rebuild a whole workspace.
• Agents do more with ardia browse, in fewer steps. read reads every matching link on a page through your logins, script loops across pages, HTML5 drag and drop works, and a background tab it drives keeps drawing without switching your view. ardia computer sets up Cua Driver so agents can use your Mac’s other apps in background windows, and ardia feedback lets an agent tell us what got in its way.

Faster

With 20 tabs open, Ardia uses about a quarter less memory: every part of Chromium 157 is smaller.

Fixed

• Closing your last window keeps it, as in Arc. Closing the only window with the red button or ⇧⌘W no longer asks “Close N tabs?” and throws your unpinned tabs away. Click Ardia in the Dock and the same window comes back with its tabs, groups, pinned tabs and the tab you were on; quitting with no window open and opening Ardia again does the same.
• Several crashes are gone: at launch with thousands of tabs, at launch on early builds of macOS 26, while loading certain images, when closing a window or moving a tab into or out of one, on an extension’s popup with no tab, when an extension changed its badge count in a window with no tab, and on Cast remoting.
• Video upscaling no longer crashes the video on macOS 27.0. When macOS refused to upscale a frame, the video flashed and restarted, about every half hour; Ardia now upscales it its own way instead.
• Thousands of bookmarks no longer freeze Ardia. With a big bookmarks bar set to Always, importing hung for minutes, every tab switch stalled and the » menu could crash the app; a folder of a few thousand on the bookmarks page crashed it too, on every relaunch. Importing 2,500 bookmarks now takes half a second, and on the bookmarks page ⌘A selects the whole folder, ⌫ deletes it and Undo brings it back.
• Top Apps stay in their own profile. In 0.2.44, profiles that share browsing data got every profile’s Top Apps merged into each one. Sharing Top Apps is now off unless a profile turns it on in Settings › Profiles; delete the merged tiles you don’t want and they stay deleted.
• YNAB, Apple Store checkout and other picky sites work. YNAB and sites with similar fraud checks showed “Something went wrong” on every load, and Apple’s and the Education Store’s guest checkout ended on “Page Not Found”. No page can open the screen-sharing picker without a click now either, which stops the screen-recording prompts some pages set off in the background.
• Picture in Picture goes where you put it. It floats over full-screen apps, sits on any display, opens on YouTube TV, and AeroSpace and other tiling window managers no longer drag it back to Ardia’s workspace.
• Full screen works like Arc’s. The window buttons hide until you point at the top, then macOS’s own title bar slides down with them, with no flicker and no empty gap in the sidebar.
• Auto-hide tabs remembers your choice. Hiding your tabs lasted only for that window, so a new window or an update brought them back. It’s now Settings › Tabs › “Auto-hide tabs”, ⌘S changes it from any window, and with tabs across the top the toolbar’s first button hides and shows the strip.
• Arrowing through the command bar shows the suggestion in the field, as in Chrome and Dia. Only the highlight used to move; now a search row shows its query and a page row its address, and Esc brings back what you typed. Thanks, @narasaka.
• “Extend website color into tab bar” picks the site’s real colour. Perplexity’s tab bar turned black and Linear’s dark red, though both sites are light. Thanks, @jrdnbwmn.
• A second Mac joining sync lists the first Mac’s profiles, even when some of the first Mac’s files were still downloading from iCloud as it joined.
• A window dragged to another display stays where you drop it, and snaps to its edges. On macOS 27 it slid down or shrank after the drop.
• Closing a window asks about the right tabs. Two windows that share tabs both close when you close them, and the warning counts only the tabs that will close.
• Video upscaling no longer stripes AV1 video on M1 and M2 Macs.
• Signing in from an extension opens its own window. Stylus’s cloud sync and other extensions that sign in this way put the sign-in page among your tabs and closed your window when it finished.
• Clicking a tab you can see no longer scrolls the sidebar after you’ve switched to another profile’s page. Thanks, @maciekzygmunt.
• The profile switcher’s icons have room. With “Show profile icons instead of dots” on, they sat so close that a click often switched to the wrong profile.
• The hidden sidebar behaves at the edges. It no longer flickers at the window’s corner or opens while you hold a button near the edge, its Peek stays joined to the window as it springs open, and the back and forward history menu opens beside it instead of underneath.
• A click that drifts a few points still counts, on a tab and on a split pane.
• An agent never acts on your tab without being handed it. Its own reads and inspections open tabs of its own, and close leaves your tabs alone.

Smaller

• Top Apps tiles look as they did in 0.2.43 again, after drawing whiter in 0.2.44.
• Hover cards sit under the top strip, keep off the page’s edge and other Top Apps tiles, leave when you move onto a group’s header, and the Bookmark tile no longer wraps.
• Dropping a tab on another in the top strip groups them only with Settings › Tabs › “Drag a tab onto another to group them” on.
• Site panels close when you click elsewhere or press Esc, and the ⌃Tab switcher lists only open tabs.
• A pinned tab away from its address shows “/ title”, and “Back to Pinned URL” no longer sticks after you leave the pinned page again.
• A tab with a Peek open shows the Peek’s icon, as in Arc.
• The command bar pulses in the site’s colour when you Tab into a site search.
• The audio indicator holds for 2 seconds after the sound stops.
• A same-site page swap keeps the old page up instead of flashing white.
• Shared Top Apps hold still and don’t flash when you switch spaces.
• On a custom profile colour, the selected tab is drawn as Arc draws it, a white highlight on dark and light colours alike, with its title in black or white, whichever reads better. A selected Top Apps tile with a black icon shows its ring.
• The camera dot goes away on a slept or unloaded tab.
• A live folder’s Completed list folds open on hover instead of popping in. Thanks, @TechSupportz.
• Re-saving a password works, and a Mac still waiting for its sync recovery phrase no longer offers a recovery kit it can’t make.
• An extension’s side panel takes keyboard focus when you open it.
• The Dock icon stays right under macOS’s Tinted and Clear icon styles.
• Gemini in Chrome is off entirely.
• With sharing on, crash reports now cover page, GPU and helper crashes and crashes noticed after an update, with a little context from just before (tab and window counts, memory, free disk), never page contents; turning sharing off erases anything not yet sent.
• Help › Copy Diagnostics says which window has keyboard focus.
• ardia exec is gone in favour of ardia browse, and ardia pinned and ardia history take its place for reading pinned tabs and history.
