FWIW, there is a fixed/updated version of this extension v1.0.6.2 which resolves the search field focus issue when triggering the popup via the keyboard shortcut (which was introduced in a recent version of Firefox) and few other minor topics/issues mentioned in the review comments by @pwrsurge and @reid.

Thanks go out to this extensions author Kevin for his great port, and his tips and suggestions on extension development. His tips and past work made 1.0.6.2 easy work.

The v1.0.6.2 signed but unlisted XPI can be found on a thread on the original Chrome extension GitHub repo. It is against policy to submit URL's so do a web search for: babyman/quick-tabs-chrome-extension issue 189

and then search the page for 1.0.6.2, you should find the full details.

Very useful addon when you reguarly have lots of tabs opened. Only major issue is poor search peformance as one gets done on every keystroke. This means that a search gets done after entering every single character which is useless.

This can be fixed with the following simple change to popup.js in order to only search when the string is 3 characters or longer.

On line 665 of popup.js:

Change:
if (!this.shouldSearch(query)) {


to:
if (!this.shouldSearch(query) || query.trim().length < 3) {

Hopefully the above fix can be implemented in a future add-on version. A user configuration option could also be added to specify the minimum length instead of having it hardcoded to 3.

For anyone having an issue with the scrollbar covering the close button, add this to its css:

.item {
margin-right: 18px;
}

Unlike the original, the ported version is sometimes in the wrong order of recent opening.

Essential for people who use tabs!

The only issue I have is a bug where the "close tab" icon is obscured by the scrollbar. You can see this in the screenshots. This behavior was tested on Windows 10 and Windows 11.

Finally, I found it!

only a few words I LOVE IT PERIOD it lets me know exactly how many pages i have open at times it can be 30 lol or more and this works as said and cant speak enought about it thanks dev ~Dave IT security specialist

This is great! Really appreciate someone ported it. Can the author also share the source code so I may be able to help fix bugs? Right now, searching while no matches does not work well.
Not sure how to reply so I am editing my comment here. Thank you for the quick response. What I meant is actually the source repository like git repository so I can send the pull request and share the fix with people.

All day, I have been trying out many addons like tree style tab, all tabs helper, tab search, Tip tab, tab manager v2, etc, etc. Each of these have at least one issue, against my liking:

Tree style tab: No search option

All Tabs Helper: No keyboard navigation. Moreover needs the highest level permission to access all the info you browse.

Tab manager v2: overrides my ctrl+t option, and there is no way to change shortcut.

Tip Tab: Nice one with visuals. But requires highest level permission.

All of these are quite slow even on the fastest mac.

I came across this little addon, which has everything anyone would want in a tab listing and quick navigation. It's extremely fast. It searches the bookmarks as well, in case the page is not open.

Excellent add-on. This should be the best easily.

That's right. I switched from Chrome to Firefox too and this addon was the thing I missed the most about Chrome. Many thanks!

Absolutely brilliant.

Almost switched back to Chrome because of this extension (which at the time was only available in chrome). Essential is the best way to describe this.
