Sumthing tells me you aren't the avg nix ... or VL user though nightflier. First distro I used as an actual hard disk install was Linux Mint. They make installing .deb packages from outside sources a bit easier if I remember correctly. Did it a few times from the actual source ( people who make/release the software.) Got rid of LM. Cause it didn't make sense to spend 4hrs tweaking an install to lighten it up. When someone can just install something like VL light, antix ... etc and be good to go with the default. Plus they are closely based on ubuntu. Personally cannot stand ubuntu and think they're the most overrated, hyped and undeserving nix distro in history. Not to mention vast majority of buntu is just rebranded Debian testing code apparently.
In LM did it both by installing via .deb package and just adding the mozilla repo/ppa etc.
Not sure how to manually install a program in VL light atm. Still too nix newbish ... Would be a nice thing to learn though. Until then am stuck with FF 3.6.xxx, shrugs. Trying to devote more time to learning linux. Though it does take a considerable amount of time and we all have other things pressing on our time. I'm trying to start an online services business. Which it's ridiculous how many t's there is to cross and i's to dot with things like that ... sighs.
Guess just have to go with live and learn ( a lil bit at a time.) Might eventually be a 1/2 proficient linux user someday.
Doesn't help having quite a few different distro's installed either. Some debian, some slackware ... one independent. Not everything works consistently the same across all of them. Makes it tougher than just having one to focus on. Though have nobody to blame except myself there. For going overboard with the distro hop. There's just too much great linux in the world to just have one imo, lol.
Chose to stop at 3 installs, but there's another 20 distro's I'd like to try. On top of the dozen I've already gone through. Back to the only so many hrs in a day thing. As for google ... Mentioned I personally keep hoping something will come along that works mucho better for web search and knock them on their butts. They've been dominating the web too long already, far as I'm concerned. They can take their browser and shove it. M$, Google, facebook should all eat **** and die in my opinion, lol.
Calling an OS someone is using obsolete is just craptastic, insulting and disrespectful in my view. Like they are so full of themselves they couldn't even be bothered to phrase it better. That's insulting to the OS user and the creators of the OS ... imo anyway. Google's momma is obsolete.
