Error when trying to login to YouTube with FF

[jnelsoninjax]

I get this wonderfully helpful message:

I am able to login to YouTube with other browsers, just not FF, any idea what exactly this error is and/or what I can do to correct it? I am logged into Google, I just confirmed this by going to Gmail, so it appears that the issue is YouTube and FF not playing nice?

IDK what the problem is, but I have decided to not use FF to watch youTube, I have tried it in a private tab with the same results.

try opening a run box and typing firefox /p 

 

this will let you create a new firefox profile. Try it on the new profile.

It was turned off, but I went ahead and changed the value to 5 so it will never turn on unless I tell it to.

What AV do you use? Would it be Kaspersky by chance? I saw reports on a forum that Kaspersky was causing issues in Firefox causing with error 405 on YouTube.

Yes it would happen to be Kaspersky. Did the forum offer any workaround?

This issue is odd because when it wants to login, it is already been logged in, and if I just refresh the page, then it suddenly reverts back to showing me logged in, etc.

Also channels that I specifically say do not show, keep showing up in my list, and then about half the time, when I click on the 3 dots menu, the option to not show is not there, the only option is add to queue.

"This is a known issue with Kaspersky 21.1.15.500 that will be fixed in the next release. You can avoid it by turning off Inject scripts into web traffic to interact with web pages in network settings."

This tend to happen from time to time. Have you tried using private browser mode or incognito? If it works, then try cleaning the cookies and site data.

 

Cookies tend to corrupt themselves and wreak havoc across the entire Google family of suites.

I cleared the cache and cookies last night with CCleaner, private mode yields the same problems.

I can login to the youtube site in Firefox 78.3 ESR without any problems on Win10 which I just did moments ago 😁

i'm not using any 3rd party AV - just WD (windows defender)

 

what Firefox version is OP using?

 

edit - I'll try using another w10 PC that has Firefox 81.0 and post back later if the youtube site works

[erpster3]

weird.

 

I actually got that 405 error message when logging in to the youtube site running Firefox 81 w/ the ublock origin, noscript & youtube no buffer addons enabled on that other PC
I then cleared the cache & cookies from Firefox using the "clear recent history" menu option (rather than using a 3rd party app like ccleaner) - closed & reloaded Firefox and logged onto the youtube site and the login was successful & the 405 error message never came back

 

I guess for me, that 405 error message was a "one time" thing on my end

[jnelsoninjax]

Using FF 81.0, but since I disabled the inject scripts option in my AV, it is working fine.
