Why the fuck is this happening?

why the fuck is this happening?

yes

Because Firefox is a shit browser.

set privacy.resistFingerprinting (false) in about:config

legend thank you

Why don't you want to resist fingerprinting in your browser? Don't you like privacy?

I'm not necessarily saying you don't want it, or vice versa for that matter, just that if you enable it, firefox will try to conceal the actual version you are using from someone who may try to fingerprint you. Which is why his version showed 52.0 when he wasn't using 52

i bet you are gonna blame your suicide on bystanders error too, good luck

Firefox has long been shit and bloated. They've been making retarded decisions and adding useless features for years, just check their fucking support forums.

Reminder that getting rid of this man purely on the basis of muh feewings was simply the first of these many errors.

just use youtube-dl instead of that extension

Pretty much this.

>privacy settings hides fucking browser version
wow i truly feel more secure now

Did you enable resist fingerprinting? If so that's why.

nobody gives a shit to update addons

Why wouldn't you use Quantum?

This happens becauseyou spoofed your user agent. You don't need to change it, though. Right click on the Add to Firefox button and select Copy Link Location. Paste the link in the location bar, load it in the same tab and it will install the addon. If you open it in another tab, it usually tells you the addon isn't trusted.

>can't use youtube-dl

>implying chromium-based has a privacy setting for that
ITT

In the future, this question belongs in /sqt/

You can download the addon anyway, shitposter.
