1 | # tab-deduper
2 | WebExtension to clean up duplicate tabs. Tested in Firefox.
3 |
4 | # Availability
5 | Available on AMO here: https://addons.mozilla.org/firefox/addon/tab-deduper/
6 |
7 | ## Operation
8 | When a tab's location changes, it checks against currently open tabs in the
9 | same window. On a match, one is made active and the other is removed.
10 |
11 | Great for tab hoarders that revisit pages that are already open in a different
12 | tab.
13 |
14 | ## Permissions
15 | Requires the following permissions:
16 |
17 | * `tabs`: To query tabs and check for matching URLs.
18 | * `cookies`: To check that two matching tabs are in the same cookie store
19 | (i.e., in the same contextual identity). Prevents closing tabs being used in
20 | other contexts, such as in different containers.
21 | * `notifications`: To notify a user that their current tab was replaced with
22 | an existing one.
23 | * `storage`: To store extension settings.

1 | ## NameAMO Description translated in Bulgarian
2 | Дедупликатор на раздели (Tab Deduper)
3 |
4 | ## Summary
5 | Автоматично разчиства дублиращите се раздели.
6 |
7 | ## Description
8 | Бивша минималистична алтернатива на Duplicate Tabs Closer, преди авторът ѝ да я пренапише като WebExtension.
9 |
10 | Идеална за хора с много отворени раздели, които често отварят в нов раздел страница, която вече имат отворена.
11 |
12 | При промяна на адреса на раздела, се извършва проверка дали такъв вече няма в отворените раздели на текущия прозорец. Ако има раздел с такъв адрес, то той се прави активен, а другия се затваря.
13 |
14 | Има няколко настройки, които управляват поведението на добавката.

1 | ## Name
2 | Tab Deduper
3 |
4 | ## Summary
5 | Cleans up duplicate tabs automatically.
6 |
7 | ## Description
8 | A minimal alternative for Duplicate Tabs Closer.
9 | It used to be a replacement, but the author of that plugin has also migrated it to WebExtensions.
10 |
11 | Good for tab hoarders that open new tabs to revisit sites they might already have tabs open for.
12 |
13 | Whenever a tab's URL changes, it is checked against the current window's existing tabs. On a match, one is made active and the other is removed.
14 |
15 | There are a few options to control the behavior.
16 |
--------------------------------------------------------------------------------
/background.js:

13 | };

16 | if (settings.moveOlder) {
17 | browser.tabs.move(replacementTab.id, { index: replacedTab.index, windowId: replacedTab.windowId });
18 | }
19 |
20 | /* don't focus backgrounded tabs */
21 | if (replacedTab.active) {
22 | browser.tabs.update(replacementTab.id, { active: replacedTab.active });
23 | }
24 |
25 | browser.notifications.create({
26 | "type": "basic",

71 | && newTab.url === tab.url && !blessedTabs.has(tab.id);

96 | }
97 | });
98 |

105 | let additions = {};

108 |

112 | */
