I usually have to type Ctrl+F, type the search string, and then Alt+A to toggle "Highlight all", because only one match is highlighted by default. I want the "Highlight all" button to be always on, and I don't think I'll ever need to turn it off.


  • "Highlight all" has to be re-enabled by the user for every page.

  • "Match case" stays toggled when you switch between pages.

Which is the wrong way around from a usability perspective.

Searching for some time did not yield any good results. This thread addresses the problem, but the solution there (Find Toolbar Tweaks plugin) doesn't work with newer versions of Firefox. The plug-in's page doesn't list any recent updates.

Is there a plug-in or a setting to get this standard behaviour in Firefox? (Chrome, Opera, and even IE all behave sensibly in this regard.)

Sadly, Mozilla intentionally does not do this. See – inanutshellus Jun 23 '14 at 18:12
@Gabriel The argument being that if "Highlight All" is on and a single letter like 'e' is typed, the contract of the functionality is that every letter 'e' on the page will be highlighted as you type, which will cause a major slow-down for large web pages. (This behaviour is highly annoying in Chrome.) The obvious solution there is to make the search-and-highlighting process asynchronous and low-priority, so that it won't block further user actions and will progressively highlight more and more matches, given time. Appropriate feedback that it's not finished yet can be given in the findbar. – Evgeni Sergeev Jun 24 '14 at 2:37
Yes, that insight is also in the Bugzilla ticket and was apparently ignored. – inanutshellus Jun 24 '14 at 12:33
@Gabriel It seems to be ignored because nobody wants to work on it. Probably a tricky thing to implement for what may be seen as a small gain. However, thinking about the number of users of Firefox who all use this feature every day, and remembering all those multi-million dollar scrapped projects with much more impressive functionality, except that they are sort of impressive in a vacuum, having zero users now, I think the utility/effort ratio for this feature is actually quite high. – Evgeni Sergeev Jun 26 '14 at 23:18
And the "just always highlight all" feature request in addition to Gabriel's (better) remember highlight all button state request. Let's upvote them! – Ciro Santilli 六四事件 法轮功 包卓轩 Mar 4 '15 at 14:10

You could try the latest version 1.3.4 of FindBar Tweak.

The "Highlight All" checkbox can be found in the extension's "Highlight" preferences panel.

It works. I was already wondering if it's possible to write a Firefox add-on to do this, in a few minutes. But I can't see it taking less than an entire evening, in which case it wouldn't be worth it. It's surprising that Google didn't show any up-to-date solutions on the first page of results — I assumed it means there isn't one. – Evgeni Sergeev Sep 9 '13 at 13:23
How do you get Findbar Tweak to maintain the highlight on page reloads? – Matthew Lock Aug 12 '15 at 8:07
Ah it's just buggy! It seems to frequently forget to highlight the word even though it highlights the occurrence in the scrollbar – Matthew Lock Aug 12 '15 at 8:14

The extension Highlight all will highlight all occurrences of a work by double clicking on a word. I don't know if that will help you with what you want.

I couldn't find a way of toggling the highlight all button in about:config, but the case-senstive toggle is listed there, so it's probably not directly configurable.

Yes, I've seen "HighlightAll" too, but I think that means I'll need to double-click a word every time, which is not better than having to click "Highlight all" or typing Alt+A. – Evgeni Sergeev Sep 9 '13 at 4:01
