and yes, almost worthless. In fact, it sux.
Badly.
Back when it started, it was "edgy", in-the-face of IE and other come-uppers.
Did their own thing, and those of us not so much main-stream loved it.
Not any more.
Now for add-ons they have to be submitted and approved by Mozilla.
Tabs are Chrome...have to add on to get square tabs back.
Always trying to update itself (and those of us that czech out updates first don't want that).
I have twelve extensions and two plug-ins currently.
Then there is Thundertird.....errr...Thunderbird. What a crock.
On my desktop I have the .exe for FF 12.0....as far as I am concerned, "last known good".
I can load it back in when FF gets wonky.
And they don't get "in-your-face", MicroSlime, and say "we're going to support old OS in defiance of MS desires for world domination"....oh, no. Roll over and play dead.
