I love Firefox, I use it everyday, I can't imagine using a browser without Tree Style Tab, or all the things that I can do in about:config.
At the same time, I can't shake off the dreadful feeling that it will eventually die one day. The market share keeps falling year by year.
What is the most realistic future for Firefox?
I'm in the same boat and have the same worries. I give them a monthly donation to support the company, in hopes of showing that there are paying customers they may be able to fall back on in the future. I can't think of anything else I can do to turn back the tide of the advertiser-developed browser. (Yes, I already know the money doesn't go directly to Firefox development today, thanks.)
Thank you for this inspiration, I've created my monthly payment now. I cannot imagine being forced to use anything else than Firefox... (Even though the Android version is barely usable after the rework...)
It's compatible with many add-ons missing from FF on Android and has some additional features that were "lost" in the Fenix release.
