I have a number of opened tabs and I want to search for a word in all of them (just as you would do in any decent editor on you desktop).

I found an extension Find In Tabs, but its outdated and doesn't work for recent versions..

if you don't find an alternative to this extension, you may still be able to use it in your version of firefox by bumping the max version. it's something I do quite a lot as I use the latest nightly builds from the trunk (3.7*) and branch (3.6.6) If an extension is relatively recent it should work in the 3.6* builds. Here's how:

  1. Open the 'find in tabs.xpi' file with a zip like utility, I use 7zip but winzip/peazip/winrar etc will work.

  2. Open the 'install.rdf' file in the archive with a text editor and find the line


  1. Replace the value of 3.5.* with the version of firefox you are using; This can be found if you open the help menu and click the about link.

  2. Save the file back into the xpi archive and close the archive.

This should now allow the extension to work in firefox.

There are other ways of doing this, for example the extension MR Tech Toolkit has an option for overriding compatibility checking. it can also be disabled in about:config Extensions . checkCompatibility - MozillaZine Knowledge Base

That worked, thanks for the tip. I'm just wondering why one would choose to restrict the max version compatible if there was no breaking changes.. – merv Jun 14 '10 at 16:31
Unfortunately, not all extensions can have their max version changed without breaking or loosing some functionality. To some extent it depends how the extension has been coded. Usually, if an extension works with, say 3.6.3, and you have updated to 3.6.4, there's a pretty good chance everything will work as expected. – Pulse Jun 14 '10 at 23:53

Just put a % yoursearchtext in the adress bar of firefox. For example: % firefox You will get a dropdown box with all results.

The Fastest Search addon allows you to do simple text (whole-word supported) or regular expression search in all tabs or only the selected/filtered tabs. It has many other useful features as well that'll save a lot of time for everyday browsing/searching.

How about a disclosure that it's your product? – dnbrv Mar 16 '12 at 3:25

There is new addons for that:

  • Hugo

    Search all loaded tabs- similar to Find in Tabs, etc. except has much more functionality. This is a comprehensive tool designed for doing research. Please see screen shots and description.

  • FindBar Tweak

    Anything between simple tweaks such as placing the findbar in the top corner, to the powerful "Find in All Tabs" tool, FindBar Tweak will make your find toolbar "just right"!

FindBar Tweak addon with last update (1.1b2 - beta now) included Find In Tabs code. (Apart this feature this can also show markers in scrollbar like Chrome and move findbar)
