Works like a charm. Specially when you're a developer and want to highlight the same instance of a variable and find where they are.

Martin Chamberlin 2025-08-01

Perfect. Does exactly what it says.

Perfect extension

Feature request, when there is a really long string, gmail adds <wbr>, within the long string <p style="font-size:18px"> <wbr>really_long_string<wbr>_really_long_string<wbr>really_long_string_<wbr>_etc </p> It would be great if Selection Highlighter could deal with this, thank you.

Awesome extension. It makes my work more efficient. Just one minor suggestion: the extension may block the page for long time when the page is huge and there are tons of selected text. It would be great to limit max number of instances to speed up, because most of time we don't really need to see thousands of instances highlighted.

Very good! 💪🏼

It kind of works, but the annoying thing is that it doesn't function for symbols. So searching something like * or + alone won't work...and guess what I needed this for. :')

Jim Sneeringer 2024-11-10

Maybe I'm dense, but I can't make it work at all. Instructions might help, or maybe it's just broken.

Quite helpful!

Works perfect (without searching, without button click, just double clicking one word is enough)

Will Chang 2024-07-11

Good stuff! Really easy to use and helpful for people who are hard to find same words in a webpage.

Why does the highlighted word , the highlight disappear with one click? How to make the highlight stay fixed until the next word is highlighted?

Łukasz Kurzyniec 2024-01-15

I love this extension! Super easy to use, Real time saver for me.

Dodgy Woodcock 2023-11-25

Works great! Could you tell me how I can leave the word that I originally marked highlighted? I need the original word to remain highlighted as a marker after I deselect it with the cursor. How to get this behavior?

Jake Z 2023-04-27

Exactly what I wanted. Double click a word and it highlights all occurrences on the page. I like how transparent the developer tries to be.

Love this extension, simple and efficient. Wondering if there's way to toggle multiple highlighting, i.e when selecting new words, add the new highlight (maybe in a different color) and also keep the previous highlight. There are some cases that I want to grep for multiple keyword. Thanks in advance.

Muito prático. Todos os desenvolvedores deveriam disponibilizar o código fonte da extensão como esse cara. Parabéns

Love it but in the last week or two it seems to have stopped working for me.

Works but not on Google Docs which I'm trying to use it for so I can mass edit docs.

Selection Highlighter is the fastest Highlighter Addon :) Suggestion: make multi highlighting per STRG. Every text selected with Strg key gets also marked :)

I was getting irritated trying to follow some things and about to go write one of these. Yours works perfectly, thanks for saving me the time and keeping open source.

Five stars! It's so simple, and yet I can change everything in the Options page. Color, regexp...this is an amazing extension. Love it, can't live without it! Doing code review without this extension is much much harder. Once again, amazing work! Love this one

It's very useful extension, but there's a problem with the extension in code snippets in Microsoft Docs site, for example: https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-5.0&tabs=visual-studio#authorization-for-specific-endpoints try highlighting text in the code snippets area
