We have a wireless Logitech M305 mouse that we use with our laptops. When the mouse is plugged in and we are using Firefox, the status bar's features either don't work or are somehow disabled. The drop-down arrow won't drop-down and stay open - it's as if it's trying to pull down a list of the sites you've been to, but it "blinks" and doesn't stay open. Typing a frequently-used word will cause it to "blink", too. Of course, when I unplug the mouse and use the touchpad, the drop-down arrow works just fine. But I find it hard to type with the touchpad engaged. I'd much rather use a mouse. Also, this doesn't happen using IE (which I can't STAND using). A techie person had once directed me through how to fix this, but I can't remember what we did. I've done everything suggested already, and nothing has worked. That includes: - experimenting with restarting the computer (with mouse off, with the mouse plugged in, etc) - uninstalling and reinstalling Firefox - starting Firefox in "safe mode" - uninstalling and reinstalling the mouse (even though it's plug-and-play, I found a software download through the manufacturer)... oddly, I'm also having problems with my computer's and mouse's settings (the volume, for example, will change on its own, the pointer speed changes on its own, etc). - disabling the hardware settings in Firefox None of those things have fixed it, so please don't suggest them again.
