Good afternoon or evening. Where can I see what vulnerabilities this or that browser version has? Do I need to update the browser to the latest version for protection, if I already use the Ublock, NoScript, https everywhere extensions, WebRTC + is disabled, I change the user agent.

The newer the browser, the less vulnerabilities. I will explain. The fact is that in old browsers

  1. Many bugs
  2. It does not contain all modern HTML, JavaScript, CSS and so forth.
  3. There are vulnerabilities

Of course, in the new version of the vulnerability, new ones may appear, but they are most likely unknown until the hackers, or few people know how the browser creators find out about the vulnerability, they fix it.

But in older browsers, vulnerabilities are well known and can be used against you.

PS: Using the old browser you create a headache for developers, as they have to maintain the old functionality in the site code. Personally, in my code I don’t do support of old browsers at all, I know that it’s not only me who does it. So using the old browser, some sites may not work for you at all.

    What may need the old version of the browser?

    • To check the compatibility of your site with all versions of browsers . To do this, it is easier to have several virtual loaders, as testers do, rather than endangering their main system. In addition, most users browsers are still updated.
    • If there is an addition that will not work with the new version . In my opinion, it's still not worth it, it's easier to find a similar addition. For example, my favorite QuickDrag I successfully replaced with FireDrag.
    • Favorite casual toy does not come in a new browser . Yes, many flash games just stopped running in new versions of Firefox and Seamonkey. But for the sake of toys to endanger your computer? I have a separate computer for children's games, they torture him. Once every few months, I stupidly restore the system from the mirror being turned off.
    • Some really necessary application does not work with the new browser . I know that our accountants have some modules for auctions that refuse to work with new versions until the support updates the modules. Well, here, perhaps, the only time when you can not update the browser, but you need to carefully monitor what is happening and be sure to upgrade as soon as the opportunity.

    Therefore, it is better to upgrade - you will reduce the likelihood of picking up some nastiness and the fact that some resource will be displayed incorrectly.
