Latest version
Version 1.12.0
Released Sep 10, 2026 - 93.63 KBWorks with firefox 58.0 and later1.12.0 - 10.09.2026
- Link Opener now runs across every selected/highlighted tab in the window (not just the one you right-clicked), merging matched links from all of them into a single queued batch, same "selected tabs" scope as Video grid/Collect Filters
- Link Opener: added "Skip hidden links" setting (on by default) - links that aren't actually visible on the page (e.g. hidden by an ad/tracker blocker like uBlock Origin) are no longer opened
- Added "Sort tabs by title" and "Sort tabs by url" context menu items, reordering every tab in the window (pinned and unpinned tabs sorted separately); internal browser pages (about:, moz-extension:, etc.) always sort to the end of their group instead of alphabetically among regular pages
- Added new "Replacer" tool: rules (url---find---replace, or ---find---replace for all pages) that find-and-replace plain substrings across a page once it finishes loading - both in visible text and in the href/src of links, images, video and source elements. Off by default.
- Added "Block forced image downloads" setting: some hotlink-protected image hosts send a Content-Disposition: attachment header on the image response itself, forcing a save-to-disk even on a plain click/navigation - when enabled, that header is rewritten to inline for image/* responses so the image displays normally. Off by default.Source code released under GNU General Public License v3.0 only
Older versions
Version 1.11.0
Released Sep 8, 2026 - 87.55 KBWorks with firefox 58.0 and later1.11.0 - 08.09.2026
- Added new "Link Opener" tool: configure rules (url---text, same format as Closer/AutoOpener) picking which links on a page should be opened in new background tabs, plus optional per-site timing overrides (url===delay===waitForLoad) for sites that need to be opened slower/faster than the global default. Run it from the "Link Opener" context menu item; a toast reports how many tabs were opened (and how many were skipped)
- Link Opener: "Collect clicked items" and "Filter opened elements" toggles (both on by default) keep a running list of already-opened links and skip them on future runs, so re-running Link Opener on the same page doesn't reopen everything again
- Added "Close tabs" context menu item, doing the same thing as the Closer tab's "Close Tabs" button (using the same saved rules) without needing to open the popup first
- Removed "Video grid all tabs", "Video grid all tabs (more frames)" and "Collect Filters All Tabs" context menu items - they were rarely used and easy to click by mistake instead of their single-tab equivalents
- Video grid: if a video has no resolved source yet (common with custom/lazy players), it now automatically tries to start it (muted) before giving up - clicking the video itself and then common play-button overlays if needed - instead of only showing a "start playing it first" toast. Opt-out via the new "auto-play nudge" settingSource code released under GNU General Public License v3.0 only
Version 1.10.1
Released Aug 27, 2026 - 77.42 KBWorks with firefox 58.0 and later- Video grid: lowered default per-video capture concurrency and made it back off automatically when a video's CDN is slow to respond, instead of always hammering it with several simultaneous requests and timing out
- Video grid: capture work for videos on the same domain (across tabs/frames) is now fully serialized - one video finishes before the next one on that domain starts - instead of sharing a pool of simultaneous requests that could still interleave and time each other out
- Video grid: no longer takes over the whole screen while still loading - shows a small top-right widget with progress and a cancel button instead, only switching to the full-screen thumbnail view once every video on the page is done; closing that view keeps the result available behind a toggle button instead of discarding it
- Video grid: the tab title is now tagged with [L]/[L done/total] while loading, [W] once done, or [F] if a video failed (e.g. a CDN timeout), so you can tell what's happening in background tabs without switching to them

Version 1.10.0
Released Aug 27, 2026 - 72.26 KBWorks with firefox 58.0 and later- Added a new "Video grid" mode: builds an NxM contact-sheet image from a page's <video> elements, including ones living inside cross-origin iframes. Each frame is labeled with its timestamp (e.g. 2:25:25), a list of URL substrings can be excluded, an on-page progress indicator shows status while it's being built, results are cached per page so reopening the same video doesn't rebuild it, and capture work is coordinated across every tab/frame so it doesn't flood the same video source with too many simultaneous requests
- Added "Video grid all tabs" menu item, to build video grids for every tab in the window in one action
- Added a "more frames" video grid option in Settings: enabling it adds two extra context menu items with their own configurable column/row count, for switching grid density without editing settings every time
- Renamed "Collect Filters Opened Tabs" to "Collect Filters All Tabs", and added a new "Collect Filters Selected Tabs" item that collects only from the currently highlighted tabs instead of the whole window
- Tab Closer: closing tabs now also removes duplicate tabs (same URL), always keeping one of each
- Added "Reverse Close" button to Tab Closer, that closes all tabs except the ones matching the rules
- Auto Opener rules can now specify a number of retry attempts (e.g. url---text---3), and a new url>>>N rule format to open the largest image on a page whose width and height both exceed N pixels
- Fixed "Wait for full page load" tab opener getting stuck forever (blocking every remaining tab in the queue) if a tab was closed while it was still loading

Version 1.9.2
Released Jun 21, 2026 - 47.27 KBWorks with firefox 58.0 and later- Added new Auto Opener tool, that automatically clicks an element matching configured text once a page finishes loading, with per-domain rules
- Removed standalone Options page, all options are now managed from the popup Settings tab
- Improved performance of "Collect Filters Opened Tabs" by collecting from all tabs in parallel and batching the save into a single storage operation
- Cached normalized filter/exclusion lists to speed up repeated image filtering
- Allowed fractional delay values when opening tabs in Opener mode
- Fixed splitting of links containing multiple #, & or spaces in Links mode
