I can't move desktop files recently sent via gmail unless I close firefox. This is new. What is causing this?
Although this a new issue for me, apparently it has happened before. I found just exactly this question, with no solutions and the thread marked closed, here: https://support.mozilla.org/en-US/questions/743177
Why was the thread closed with no answers?

The Question posted on 2010, so its closed.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
To Enable SafeMode
- You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
- Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
- Once you get the pop-up, just select "'Start in Safe Mode"
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")
It is also possible that security software is locking the files, so check there as well if Safe Mode doesn't have effect.
