pubmatic ad running on my computer without permission! Other extensions are doing this like LanguageTool and Metamask even. Disable them or get this useless junk off of your browser.

I sure can't figure out how to use this. Not very intuitive.

After 5.1.2, I can't see any highlighted results in editable fields (test boxes), but the found number is only shown on an icon of menu bar. I hope to check and correct it immediately. Or could you tell me how to install older version ? Because I need this addon for work.

Thank you for your quick revised action! But some type of text boxes are not highlighted yet. In older versions, those boxes were highlighted.

Working great on PC, does not seem to be working on Android. The add-on does not save settings and thus I am unable to create and save the word list to higlight text.
