Tonight a twitter cookie of mine expired and I was shunted again into #newtwitter.
Twitter offers a link to switch back to #oldtwitter, but it’s been broken for months now.
I did some digging and found the expired cookie entry in ~/Library/Cookies/Cookies.plist:
<dict>
<key>Created</key>
<real>322609921.51493198</real>
<key>Domain</key>
<string>.twitter.com</string>
<key>Expires</key>
<date>2012-03-30T21:52:01Z</date>
<key>Name</key>
<string>k</string>
<key>Path</key>
<string>/</string>
<key>Value</key>
<string>[REDACTED]</string>
</dict>
I quit Safari, moved its expiration date forward a year and was able to login into #oldtwitter again.
Update: Or not, I’ve been bounced into #newtwitter again the next day. I’ll now try enabling Feather.
