It takes a great deal of energy to create good content. It seems most people are willing to spend money to reduce that burden for their own games or at a minimum willing to spend money to create an elevated starting point for their own efforts.
I started using the AutoMute extension to automatically mute newly opened tabs and very rarely notice auto play videos. I guess I don't find the video as distracting as the audio.
Before I can choose to use it I have to install it and that's significantly less convenient than it is with Chrome.
If I go to Chrome's download page it offers up a 64 bit .deb file. Perfect and I happen to know it keeps it's self up to date.
If I go to Firefox's download page it offers up *.tar.bz2 file. I have no idea if that file is a source package that needs to be built or a binary blob for what architecture?
So, since I'm too lazy to dig deeper Firefox lost out before I even tried it.
I concur with the other commenters... I've been syncing with dropbox for years now and never had a conflict. I guess it helps I tend not to leave it open/running on multiple machines. Open it, use it, close it.
I also make mine available online but do it a bit different.
I have a public dotfiles project on Github. In addition to my dotfiles it includes a symmetrically encrypted tarfile of a secrets folder that contains keys and other sensitive info.
To recover my keys I only need access to github, gpg and the password for the encrypted tarfile.
