Version 1.13.1
Released Sep 18, 2026 - 105.6 KBWorks with firefox 58.0 and later1.13.1 - 18.09.2026
- Video grid: the "▦ Video grid" and ✕ buttons are now solid dark instead of nearly see-through - the toggle sits on the page itself, with no dark overlay behind it to make the old translucent style readable
- Fixed "redeclaration of const ..." killing any second run on the same page: running Video grid, Gallery mode or Collect links again without reloading first (and, for Video grid, capturing a video that lives in an iframe, which loads the shared code into that frame twice) failed before executing a single line. Shared top-level values are no longer declared in a way that a repeat injection rejectsSource code released under GNU General Public License v3.0 only

Version 1.13.0
Released Sep 18, 2026 - 104.69 KBWorks with firefox 58.0 and later1.13.0 - 18.09.2026
- Video grid: the overlay's close button is now exactly the same size and sits in exactly the same spot as the "▦ Video grid" button that brings the grid back, so hiding and re-showing it is the same click in the same place instead of chasing a button that moves and resizes
- Video grid: fixed running it again on a page that already had a grid going (or a finished one still on screen) stacking a second copy of the whole overlay/widget on top of the first, with neither closing the other - there was no way out short of reloading the page. A new run now takes over: the previous one is cancelled (freeing the capture slots it was holding) and removed first, so the newest click always wins
- Video grid: a second click on a tab whose previous run is still scanning/capturing no longer gets overwritten by that older run finishing later and injecting its own stale results on top
- Video grid: the tab title now says what a tab is actually doing instead of just "busy": [L] queued (waiting for a free capture slot - nothing is being downloaded, closing that tab frees nothing), [O] holding a slot and loading the video's metadata, [M done/total] actively capturing frames, [W] finished, [F] failed, and [] for a tab where the grid was started but no video/source was found at all. The top-right progress widget uses the same wording, so a stalled run shows which tabs are the ones worth cancelling
- Video grid: fixed the tab title tag stacking up ("[L 2/42] [L 1/42] Real title") for videos captured inside an iframe, instead of replacing the previous tag
- Video grid: added a third "ultra frames" grid option (default 14x12) next to the existing "more frames" one - same opt-in toggle plus its own column/row count in Settings, so a normal, a denser and a very dense grid are all one context menu click away without editing settings in between
- Link Opener: links opened in a new tab now carry the source page's URL as Referer, like a real click would - fixes some hotlink/anti-bot-protected sites showing a "not found" page for links that work fine when clicked manually
- Video grid: the "auto-play nudge" for lazy players (tries to start a video automatically before giving up, see the "auto-play nudge" setting) is now off by default instead of on - it doesn't behave correctly on every site. Added a blacklist/whitelist mode plus a list of page URL substrings in Settings, to scope it to just the sites where it's known to work (or exclude the few where it isn't) once enabledSource code released under GNU General Public License v3.0 only
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
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

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
