Long time Firefox user here. I use a metric shit-ton of addons, and customize everything drastically. "Refreshing" is a massive pain in the ass, as re-configuring everything while also maintaining the "clean settings" is just a difficult combination.
Despite this, I've completely wiped out both my settings and firefox install on several occasions in an attempt to keep things stable.
It doesn't help.
I'm aware that my addons are likely a big contributor to the memory-hogging and eventual crashes, but if I didn't want to use these addons, I'd just use fucking chrome. The ENTIRE point of Firefox is for the customizability. Dropping addons to improve stability just isn't an option for me.
I'm tired of all this "war on encryption" bullshit. Every week it's another attempt. How much longer must I cower in fear of these ignorant lawmakers trying to undermine the entire basis of security? Are they just going to keep trying until something makes it through?
I'll keep an eye on it to see if there's a specific addon triggering my issues, but it will likely stick around.
