I use Firefox sync on different PCs, and have an addon that should only be synced/enabled on one of them. How can this be realized?
Background: Zoom
One of my PCs is connected to my TV. It's used to surf on the web, watch videos, play games and so on. 100% zoom can be hard to read on some websites. Since Firefox can't zoom globally, I recently installed NoSquint Plus for this. It works well, but now I'm sitting on my main PC and I have 120% zoom here, too. This is caused by the sync and doesn't make sense for a regular computer on the table.
I don't want disable the sync for all addons because it's useful for other ones, that I use on all PCs. The perfect solution would be the ability to disable Firefox sync only on NoSquint Plus. Sadly I can't find any setting to choose which addons should synchronize.
Possible workaround
Set services.sync.addons.ignoreUserEnabledChanges
to true
(source: Firefox wiki) and disable the addon on all other machines. However, this has the side effect that changes to other addons must be applied individually on all machines. And it could be hard to troubleshoot, if I'm wondering about this behavior in the future.
