Same here. 99.9% of the time on Linux, using both Chromium and Firefox. No issue. On the corporate notebook I am forced to use IE, which is giving me a message that it will not be supported anymore soon...
Okay, so you aren't asking that Garmin update Garmin Connect to work with various browsers on the Linux platform. You are asking for them to develop application software to allow you to download your activities to a Linux system (using a plugin).
Garmin appears to be deprecating support for the browser plugins (see here). I don't understand the rationale since I don't see any browsers disabling support for plugins and extensions, but I'm sure they have their reasons. Regardless, if they are dropping support for browser plugins on Windows and on MacOS, I'd guess that they aren't going to be developing a plugin for Linux anytime soon. Chances are probably greater that they'd do a port of Garmin Express for Linux.
Ok guys, There is a fedora pacakge https://admin.fedoraproject.org/pkgdb/acls/name/garmin-sync which allows you to download information from your Garmin Edge and Forerunner devices. Then you can upload it the files manually to garmin connect web app.
You need special software for that? Doesn't the Edge just mount as a disk like it does on OS X when you plug it into a USB port? From there, you simply manually upload right from the Edge. That's the way I always used to do it on OS X until Garmin Express came along, since the plugin was always way too slow. Forerunners are another story, since they don't all use USB upload.
bumping this thread due to the new Garmin Express being launched. I can not find a way to manually upload a file anymore. I was using the garmin communicator linux plugin and it worked great. It still works great when you switch to the 'classic' version.
