I'm settling in to get some things done and notice a blurb.
There's going to be a rollout of the next Firefox over the next few weeks. I pay close attention to that because I use Firefox extensively. I'd be lost without it.
I'm so tightly trained to use Firefox that I have to step back and actually "think" how to use any other browser. Since I use Windows 8.1, Windows 7, Mac OSX Mavericks, and Debian Linux on a daily basis as well as Android and an occasional toe dipped into Apple's iOS, I have to remain as flexible as possible and Firefox is on all of those computers.
Except the iPhone but I hardly ever use them.
I will eventually install Firefox on the Windows machines when it tells me that it is available. I'm not in a rush. The last time they changed the way it looks, the User Interface or UI, it borked it for me. I ended up installing things to make it look the way it did before I updated the browser while growling at Firefox in general. Keystrokes and mouse clicks and all that moved. They removed the status bar. The bookmark strip got lost, or rather hid, and that stores some of your bookmarks. They removed the title bar.
Why? Never heard a reason, but I installed Classic Theme Restorer and it brought it all back. Immediately after that I installed Adblock Edge to get rid of the blasted adverts and other nasties that hitch a ride onto your computer as a result. More Privacy means for a faster experience as well as fewer viruses and spyware pushed onto your local computer. Nobody actually "Likes" ads anyway, we accept their presence and usually are annoyed or distracted by them, but "Like"? I doubt it.
Rule Number One of Software User Experience (UX) is if you change the way something looks, you will break the way people work. I learned that back in the days of the Mainframe and College.
Rule Number Two of Software User Experience is that if you do change it there will be unintended consequences.
In My Case:
I have a computer that has what they call a "Clickpad". It's also running Debian Linux. I know Linux in general fairly well, but Debian Linux doesn't manage Clickpads well. Clickpads are those weird trackpads that are flush with the case. You click on the pad instead of having normal buttons like every other Synaptic trackpad.
I do know that is fixed in the next version of Debian, and I do know how to fix it now, but it is an annoyance that I have to deal with. It basically forgets that it has a physical button in Debian Stable/Wheezy, and you're stuck with whatever you touch on the trackpad. I only get a Right Click when I tap. I have since configured a two fingered tap to be a Left Click.
What that all did change did is to break the way Firefox works. You see, on that particular computer, I can't Right Click. I can't get the pop up context menu. They changed the UI right away from it.
Since that machine is Debian Linux, I have to wait for the next version anyway. It isn't even using Firefox, but something rebranded as "IceWeasel". To put it short, and sarcastic, Debian had a spat with Firefox over the branding. Since Firefox/Mozilla doesn't want anything proprietary at all on their default install, someone in the Debian Project grabbed the source code, recompiled it, created the graphics, and renamed everything to IceWeasel. It works like Firefox but is Older. About a version back.
If you're running Stable, or Wheezy, you could be quite a few versions back. Jessie has a more current Firefox, but it also has a lot more annoying bugs in it because it is "Testing".
But Windows? Yeah, you'll get it soon. Just remember Classic Theme Restorer and Adblock Edge, and you'll be fine.
As for the Mac? When it is available, you'll get a blip on the bottom of the screen telling you you're ready for an upgrade. You can also go back to the old theme if you want, but I do recommend Adblock Edge as well.
Why the harping on the ads? It's a much faster browsing experience when you surf a page without the ads. No blinky pictures, crawling things, or text ads. If you don't download them, you use less data. Things pop faster.
Trust me on that one. You can always turn it off later.
