Tab Counter

Nice extension! Would it be possible to add a "deduplicate tabs" feature? For example, if there are multiple tabs with the same URL, the extension could help identify and optionally close duplicates. This would be really helpful for people with large numbers of tabs open. Thanks!

I have around 2600 tabs. This extension seemed promising at first; it didn't cause a massive CPU spike every time I opened/closed a tab, as opposed to the last tab counting extension I tried, which would instead freeze my browser for a few seconds. HOWEVER: found out later that it was causing the startup time for my browser to go from about 30 seconds to 52 minutes.

Hi there! Genuinely, thank you for this feedback! I myself usually hover between 300-500 tabs so I hadn't seen this performance issue to such an extreme degree. 100%, there's no reason for it to be that slow, I'll put some focus into this. Thanks for trying the extension! Edit: A new update has been released - 3.0.2, which should resolve this issue.

Works great. Open source. Doesn't steal my data or nag me about payment.

Pretty amazing, i wish it had a dark mode though

Just works, does what is says. 5/5

Feels snappy and has great features like closing duplicate tabs, finding tabs with playing audio, searching for tabs in current window, moving tabs between windows via extension menu. Must have improved quite a bit in the past year since the last reviewer.

bloated with broken features, slows down browser start time by considerable amount, not recommend
