Have no long time experience with this but it works with Firefox 149. Many Thanks.
Before I was using "Hide Google AI Overviews" from Zbarnz. It worked for a while but then of all sudden not.

Excellent extension! It will occasionally break/fail, but thats from Google making changes to Gemini stuff that the dev has to respond to those changes. Give the dev a moment to update the app, always, before getting angry. Thank you dev!

Needed something to block the AI summaries on YT, seems to be working well. Thank you!

Yes

No more "AI Mode" button as well in my Google results. AI mode is normally left from the All tab. Google is more crazy each day...

I do not know why I still use Google at this moment.

MUITO BOM!!!!!!!!1

Works fine in Google search, its so annoying I cant turn AI stuff off, F google. Nice job Paul

Does exactly what it says it does. Makes me much happier using google drive.
