If I highlight text on any page in Firefox 136.0, and then ask Gemini to "Explain this", Gemini opens in the Sidebar (I have selected the RHS of the screen for the sidebar), but my selected text is not entered into Gemini, and nothing happens. If I try this again while the sidebar is open, I get the message "Something went wrong, try reloading this page" Reloading the page doesn't help.
