Ok, so, right here and now, you can download the full offline installer for Firefox 51.0, go offline install it. do not install mozilla maintenance service and do not set it to auto update. turn off all updates. turn off checking for updates. in options. next duckduckgo search how to disable XPI signiature checking. go to about:config and search XPI disable any and all. next go download flash player, 32 has some bugs so I suggest something earlier atm. install. enjoy.

I also suggest to install noscript adblockerultimate, advanced cookie manager, and a user agent switcher. if you cannot get a working copy of these from mozilla's site, copy the URL and paste it in archive.org's waybackmachine and get an older version that will install.

for adblocker ultimate you'll need to install it several times from XPI file. most websites work perfectly with this browser. only a few do not. and in my opinion those websites are trash anyways. they are just trying to force the chrome standard.

also never turn on analytics.google.com or googleanalytics.com scripts. they just track you and make money off you and spy on your mouse pointer location, keylog everything you type, monitor what URLs are open in other tabs, and take screengrabs when you switch to other tabs or applications. in other words, your computer slow? yeah it's all those nonsense scripts. turn them off. javascript is dangerous.

but yeah I'm on firefox 51.0 right now and flash works fine. and it will stay that way so long as I don't upgrade. Downgrade your browser today!

just in case you can't find it.

Q: Facebook says they've ended support for this browser.
A: lol.. they actually haven't ended support; posting and chatting on facebook still works. But seriously turn off those facebook scripts before you leave the page, they'll track you if you don't even after you close facebook.

Q: I went to a website and it's a blank page or the pictures wont load, why is that?
A: javascript, the page is running everything through a javascript and some of that javascript is newer than this browser allows, and probably will bend your computer over and give it new holes if you turned on the script. Ignore that site or use a different browser for that site if you really must. Use CCleaner to clean cookies and cache after you are done, and a antivirus scan with malwarebytes.

Q: are there some scripts online that automatically force you to update your browser or disable your adblocker and break ti so it stops working all together?
A: Yes, yes there are. keep Adblocker Ultimate up to date. It will block any scripts which try to disable or destroy your adblocker. also there are scripts which will automatically check your browser version and if outdated will automatically connect the browser to the browser's developer to download the latest update in the background. Keep No-Script on at all times and be careful what you turn on out there.

Q: how do I know what scripts are necessary to run a page and which are not?
A: start with the rule, it's probably necessary to turn on any scripts from the URL of the site name and any subsequent cdn scripts with the same URL, .com and .org of the site URL probably need to be on. in other cases check in no script where it says "blocked objects" it will appear if something like typekit for text boxes or fonts are necessary to make buttons or stuff work. for videos you may have to activate scripts for the video host and the player, both of these will show what they are when you click the player. It may take several script activations and reloads to get them all. General trial and error. ads are almost never necessary unless the video player requires them loaded before it will play. And be careful of urls with things like "push" in their name. ajax.googleapis.com is usually a media player, don't be fooled by the "google" in the name.

then prominent hosts (like SWF chan and newgrounds) should keep repositories of a variety of flash browser plugins and standalone players so users can always get them here.

>buttons don't work in this browser
I really hate modern web designers. That's right, the designers, not the "modern design". Because it's the newage designers that adopt these things.

I especially hate when they can just use a normal hyperlink and when middle mouse button doesn't work to open URLs in a new tab. YouTube and many other sites have links that aren't actually real links and it drives me nuts.

Annoyed when they write "tap x" instead of "click x", then you know the web designer is one of the bad ones.

Those browsers are unfortunately too backwards (as in using old tech), I don't know what newage crap some sites use when playing movies online but they just won't play in Basilisk/Palemoon. If it's that bad now and web designers give that few fucks it'll just get worse in a few years. Mainstream browsers have just gotten so big that they don't care about the broken web they create for the less-than 1% still on old tech browsers.

or that content gets retracted from the site or stops playing
when I browse social media and the likes and you click on a vid or embed, you let it play in the background
but as soons as it gets out of screen, it just vanishes or stops autoplaying
fucking hell

I think he shouldn't, he should stay neutral on how to play the content, his job is only to preserve and host said content
how you play it yourself, is entirely up to you, it's not like you can watch flashes here without the flash plugin or anything related
there are ways to get flash to work on mobile (old versions of android firefox), so you just have to get that on your own

something like that would only contribute to even more people getting out of touch with the actual flash format which tends to bring in the worst kind of people

they didn't brick anything but the newest one.
