Like a lot of people, I dumped Firefox when Mozilla dumped a guy whose sole crime was giving a little bit of money to the Prop. 8 campaign, back before that had been reclassified as among genocide, child molestation, and singing karaoke as Great Crimes Against Humanity™.
Well, that meant I ended up with Chrome.
And while Chrome offered spiffy features that Firefox didn't, it also didn't support the array of add-ons I had accumulated over the years of using Firefox.
I toughed my way through for quite a while, helped by the fact most of my web browsing was on one or another of my mobile devices (for which these add-ons are unavailable even for Firefox) -- but since I've resumed using my Windows PC their absence has been getting on my nerves once again.
So, I'm off the wagon.
Deal with it.
