Yes, that's what I learned. How can they disable things without providing replacements? And the one extension they upgraded (NoScripts), they didn't have it pick up the current settings. Everything just reverted to defaults. That's why I didn't have the scripts which run the chatbox and smileys. To me, this is all irresponsible, and not being sensitive to their users needs. I've had this complaint with them, ever since I switched from IE. Almost every single upgrade, I have to stop what I'm doing, and reset this and that. I had already disabled upgrades, so I wouldn't be bothered. But then yesterday, I got a message saying Ff was dangerously out of date. And that's what forced the upgrade on me.
So for me, it's either revert to the older version, or just find a new browser. Maybe I won't find a better one.... But my needs are pretty simple, for browsers. I don't need cutting edge features (except for security).
From what I've heard, Opera is the best at supporting SVG. And it brags some other nice features. I just downloaded, so I'll install and give it a test drive. And there also is a Linux version, so when I switch to Linux, at least I won't have to learn a new browser.
Also like how Sea Monkey sounds. Might give it a test drive too. Last option Pale Moon.
