I made a simple firefox/chrome extension for people like you and me that horde tabs. You might find it useful to find tabs and quickly navigate to them by clicking on the link in the list. It's free and open source. The github page has a gif showing usage.
It sure it is... any idea what it should be? Firefox has a problem with re-assigning keys but in chrome you can change them inside the extension manager area. There's a bug filed for firefox to fix this.
can't bind to Ctrl-` because of some limitation of the browser and Ctrl-Space didn't work for some reason as well. I ended up using (ctrl/comamnd)+Shift+E as it didn't seem to have a shortcut assigned to it and it is very easy to use with one hand. Hopefully that works well for most people. I'll update the extensions today but it takes a few days to get code approval on firefox. Chrome update should be available within a few hours of submitting.
My next feature request would be to show the domain (e.g. "news.ycombinator.com") next to each link, like HN does. That'd let ctrl-F find by domain.
Additionally, being able to sort by domain would be good. Not per-window, but globally. Just a big list of tabs. I'm almost never looking for a particular window, but rather a particular tab of a specific site.
Another minor feature request is to put the total number of tabs as a badge number on the icon itself. I.e. instead of just showing tabist's icon, show the icon with "53" on it if I have 53 tabs open.
Or, y'know, it's pretty good how it is now, so feel free to just ignore this. :)
Those are all good ideas and I am likely to implement them. I published the new version so it should be available within a few days for firefox and within a few hours for chrome.
