Was working fine till now. But sometime in last week/month gemini results are not being shown. Only microsoft copilot results are visible(I have the other extension named "optisearch" also)

It works pretty well provided you're logged into the right Google account.
However, I have a SERIOUS concern - this extension sends ALL searches to Bard. If I want some privacy and use, say, DuckDuckGo then bard still pops up which means that my private query has been sent to the Google team.
This is a big no for me, so I'm uninstalling it.

Does what it says it does, but has a button that links to pay the creator monthly, to just link to the bard site to continue the convo, i do not see how paying the creator of this said plugin does anything other than give you a link.

Very interesting idea, but does not seem to work properly inside a Firefox container. It constanly displays "Login to Google" while I am logged in within the container.
There is also a privacy risk: while in Private Browsing mode, clicking on "Login to Google" opens a new window in the non-Private Browsing mode, making you unexpectedly leave the Private Browsing mode.
