It works great, and the design is minimally intrusive; thank you for making this.

Two suggestions: add a cancel button to cancel the deletion after it has begun, and show how many chats are yet to be deleted ("x of y deleted" or "x remaining").

And, as an added bonus, you could include the estimated time remaining. I just deleted 59 chats with this and every chat seemed to have a consistent amount of time required for deletion (about three seconds per chat). So a little "time remaining" bar shouldn't be difficult to implement.

And also a little chime (toggle-able on/off) would be nice to let the user know when the act is finished.

But simple and effective overall.

Não funciona na verão atual do Gemini, clico para deletar os chats, aguardo e não deleta.

Much much better than nothing. Worked on Firefox Portable on Win11.

Doesn't work - tried on Zen Browser on PC, Firefox browser on PC and Firefox on Android - no luck getting it working.

Works as promised.
