Question & Answer :
I person 5 addons/extensions for Firefox, Chrome, Net Explorer(I.e.), Opera, and Safari.

However tin I accurately acknowledge the person browser and redirect (erstwhile an instal fastener has been clicked) to obtain the corresponding addon?

Googling for browser dependable detection frequently outcomes successful checking the Person cause drawstring. This methodology is not dependable, due to the fact that it’s trivial to spoof this worth.
I’ve written a methodology to observe browsers by duck-typing.

Lone usage the browser detection methodology if it’s genuinely essential, specified arsenic displaying browser-circumstantial directions to instal an delay. Usage characteristic detection once imaginable.

Demo: https://jsfiddle.nett/6spj1059/

``` // Opera eight.zero+ var isOpera = (!!framework.opr && !!opr.addons) || !!framework.opera || navigator.userAgent.indexOf(' OPR/') >= zero; // Firefox 1.zero+ var isFirefox = typeof InstallTrigger !== 'undefined'; // Safari three.zero+ "[entity HTMLElementConstructor]" var isSafari = /constructor/i.trial(framework.HTMLElement) || (relation (p) { instrument p.toString() === "[entity SafariRemoteNotification]"; })(!framework['safari'] || (typeof safari !== 'undefined' && framework['safari'].pushNotification)); // Net Explorer 6-eleven var isIE = /*@cc_on!@*/mendacious || !!papers.documentMode; // Border 20+ var isEdge = !isIE && !!framework.StyleMedia; // Chrome 1 - seventy nine var isChrome = !!framework.chrome && (!!framework.chrome.webstore || !!framework.chrome.runtime); // Border (based mostly connected chromium) detection var isEdgeChromium = isChrome && (navigator.userAgent.indexOf("Edg") != -1); // Blink motor detection var isBlink = (isChrome || isOpera) && !!framework.CSS; var output = 'Detecting browsers by ducktyping:

'; output += 'isFirefox: ' + isFirefox + '

'; papers.assemblage.innerHTML = output; ```

Investigation of reliability ----------------------------

The former technique depended connected properties of the rendering motor (-moz-container-sizing and -webkit-change) to observe the browser. These prefixes volition yet beryllium dropped, truthful to brand detection equal much sturdy, I switched to browser-circumstantial traits:

Net Explorer: JScript’s Conditional compilation (ahead till IE9) and papers.documentMode.
Border: Successful Trident and Border browsers, Microsoft’s implementation exposes the StyleMedia constructor. Excluding Trident leaves america with Border.
Border (based mostly connected chromium): The person cause see the worth “Edg/[interpretation]” astatine the extremity (ex: “Mozilla/5.zero (Home windows NT 10.zero; Win64; x64) AppleWebKit/537.36 (KHTML, similar Gecko) Chrome/eighty.zero.3987.sixteen Safari/537.36 Edg/eighty.zero.361.9”).
Firefox: Firefox’s API to instal adhd-ons: InstallTrigger
Chrome: The planetary chrome entity, containing respective properties together with a documented chrome.webstore entity.
Replace three chrome.webstore is deprecated and undefined successful new variations
Safari: A alone naming form successful its naming of constructors. This is the slightest sturdy technique of each listed properties and conjecture what? Successful Safari 9.1.three it was mounted. Truthful we are checking in opposition to SafariRemoteNotification, which was launched last interpretation 7.1, to screen each Safaris from three.zero and upwards.
Opera: framework.opera has existed for years, however volition beryllium dropped once Opera replaces its motor with Blink + V8 (utilized by Chromium).
Replace 1: Opera 15 has been launched, its UA drawstring appears similar Chrome, however with the summation of “OPR”. Successful this interpretation the chrome entity is outlined (however chrome.webstore isn’t). Since Opera tries difficult to clone Chrome, I usage person cause sniffing for this intent.
Replace 2: !!framework.opr && opr.addons tin beryllium utilized to observe Opera 20+ (evergreen).
Blink: CSS.helps() was launched successful Blink erstwhile Google switched connected Chrome 28. It’s of class, the aforesaid Blink utilized successful Opera.

Efficiently examined successful:

Firefox zero.eight - sixty one
Chrome 1.zero - seventy one
Opera eight.zero - 34
Safari three.zero - 10
I.e. 6 - eleven
Border - 20-forty two
Border Dev - eighty.zero.361.9

Up to date successful November 2016 to see detection of Safari browsers from 9.1.three and upwards

Up to date successful August 2018 to replace the newest palmy assessments connected chrome, firefox I.e. and border.

Up to date successful January 2019 to hole chrome detection (due to the fact that of the framework.chrome.webstore deprecation) and see the newest palmy exams connected chrome.

Up to date successful December 2019 to adhd Border primarily based connected Chromium detection (based mostly connected the @Nimesh remark).
