v3.0.4 — New Rule Defaults & Bug Fixes
Fixed the list acting like Ctrl was stuck held down after switching tabs with Ctrl+Tab. Rows couldn't be unchecked, and clicking a row no longer refreshed the editor panel to that row's settings. Switching tabs now clears the stuck state correctly.

New rules now remember your last-used settings (new). Type, Case, Cross-Element, Isolate, and Bold on a freshly added row start out matching your most recently saved rule instead of resetting to defaults.

Fixed a rule-order bug that could partially undo a chained replacement. Adding a new short rule after a longer chained one could tear the existing result apart — e.g. an already-correct 123456 reverting to 12cd56. Broader rules now reclaim their ground correctly no matter when the shorter rule ran.

Fixed WR3 breaking dynamic reader sites (e.g. WTR-Lab), sometimes leaving them stuck on "Loading." WR3 was force-tidying large chunks of the page's live text nodes on every check, which could invalidate node references the site's own script was still holding. WR3 no longer does this.

Fixed WR3 stalling dynamic reader sites with a large number of Cross-Element rules. WR3 was re-scanning the whole surrounding paragraph from scratch for every active Cross-Element rule instead of once per check, which could lock up the tab on a big list. It now scans each area once per check no matter how many Cross-Element rules are active.

Fixed WR3 still freezing large pages/lists over time (e.g. long WTR-Lab chapters), even with the two fixes above. A background safety check was re-scanning the entire page on a timer every 1.5 seconds, forever, whether or not anything had actually changed — on a long page with a big list, that adds up until the tab stops responding. It now only re-scans when the page has actually changed.

v3.0.3.1 — Cursor Fix Follow-up

Finishes the cursor-jumping fix from v3.0.3:

• Pressing Enter to start a new line in a chat box or text field no
  longer misplaces the next character you type.
• A replacement made elsewhere on the page while you keep typing no
  longer bumps your cursor back to the start of the line.

No new features, no changes to how rules match or replace text.

New:
- Delete all results while searching — clears every matching row in one click (undoable).
- Toast toggle — turn off the "X replacements made" notice for silent replacing.

Fixes:
- Rule changes now apply live to already-open pages, no refresh needed.
- Fixed overlapping rules producing duplicate or wrong-case replacements.
- Fixed "+ New" adding rules on top of search results instead of the real list.
- Fixed "+ New" rows inheriting settings from an unrelated existing rule.
- Fixed checkboxes sometimes unchecking themselves after Apply.
- Fixed matching against double spaces, tabs, and non-breaking spaces.
- Fixed Swap-type rules getting stuck with leftover placeholder text.
- Fixed \C and \L RegEx case tokens doing nothing.
- Fixed the Test box occasionally disagreeing with real page behavior.
- Fixed intermittent export/download failures in Firefox.

Performance:
- Faster typing in Find/search/Test boxes; saves are now batched.
- Much faster matching on large rule lists (25–30x at 13,000+ rules), with no change to which rules fire or in what order.

Firefox port of Word Replacer III (v3.0.2)

• Fixed manifest id mismatch — now matches this add-on's registered AMO ID
• Background script uses scripts instead of service_worker, since Firefox's MV3 implementation doesn't run service workers
• Added strict_min_version: 115.0 (Firefox's signing root cert requires 115+ to validate signed extensions)
• Added required data_collection_permissions disclosure:
• required: none — core find/replace and storage need no data collection
• optional: technicalAndInteraction — covers the Share Link feature, which sends encoded replacement rules through TinyURL's API when a user opts in

No code changes were needed beyond the manifest — all APIs used (chrome.storage, chrome.tabs, chrome.runtime, etc.) are standard WebExtensions APIs supported natively by Firefox.

v3.0.1 — Bug Fixes & UI Changes
Real-time replacement counter. The count in the search bar now updates live when you add or remove rules.

Checkbox no longer disappears on Apply. Selecting a row and clicking Apply to Selected no longer loses the tick.

Sort Replace fixed. Sorting by Replace word now correctly sorts by each row's replace value.

Replacement words no longer go missing. Unsaved rows are preserved correctly when the list re-renders.

Duplicate highlighting now works in real time. Duplicates are highlighted as you type, no refresh needed.

UI. Modified some UI elements.
