Just as the title explains. Firefox isn't updating any of my extensions. I hit detect updates, it says it didn't find any, but several blue icons on the extension page show up stating that the extension can be updated. When I select it I am able to click "update", but, as those quotation marks suggest, it does absolutely nothing. Restarting the browser also does not update the extensions. The only way I can get them to update is if I remove and read the extension.
