Meaning

Tab — a browser tab; one of multiple open pages in a web browser.

Borrowed from English 'tab,' this term is universal among internet users. The common experience of having too many tabs open (タブ開きすぎ) is a widely shared modern complaint. Having dozens of open tabs has become a personality trait joke — people who keep many tabs open are said to be either organised multitaskers or digital hoarders.

Examples

1. タブ開きすぎてブラウザが重い。 I have too many tabs open and my browser is lagging.
2. さっき開いてたタブどこいった？ Where did that tab I had open earlier go?
3. タブ100個開いてる人の気持ちがわからない。 I can't understand people who have 100 tabs open.

Do Say

Don't Say

• タブとウィンドウを混同しない — タブは一つのウィンドウ内の個別ページ (Don't confuse tab with window — a tab is an individual page within one window)

Common Mistakes

• Confusing タブ (browser tab) with タブ (keyboard tab key) — context determines the meaning
