Anything that goes towards power reduction will be helpful - that includes notifying the user of background (and possibly even foreground) tabs that consume a lot of power (or CPU cycles) when on battery power. Automagically hibernating background tabs (maybe with a whitelist for tabs you expect notifications from) would also be an excellent start. Rounding this out with a way to throttle foreground tabs' timers etc. and disable animations until they're clicked on while on battery would pretty much complete my entire wish list...
It could be added as a battery saving feature that extends battery life by between 20~25% without sacrificing performance. When browsing on a laptop without being able to connect it to power, it is a great advantage to be able to save battery, especially when you need the device for work and study.
I agree with most here. I think a lite version of Firefox or some sort of mode toggle to be a bit more power efficient would be a great addition for us laptop users.
make a battery saver and memory saver feature for firefox to make it further efficient and to recommend to other people with laptops because it battery life is very much important to all laptop users who use their laptops unplugged
Asking some friends of mine about why they don't use Firefox and that's because other browsers has resources cap options that could limit memory and cpu usage. Firefox could add this and then simply enable a preconfigured option for battery safe mode.
This should be the key part for being in scene with other browsers. Having this + MV2 support will be overkill for the competece
