Sounds like a cache issue as already answered by @Matt Ball.As far as the RSS feed, the end user tells the browser (in preferences) how often to update his feed.
I upgraded my system and besides all Google Chrome was updated to version 53.
What I have noticed immediately after the upgrade was that there was no Google Chrome icon in gnome shell anymore.
I looked into launcher and found what it was trying to run: $ ls -ld /usr/bin/google-chrome /usr/bin/google-chrome-stable /usr/share/applications/google-chrome.desktop ls: cannot access '/usr/bin/google-chrome-stable': No such file or directory lrwxrwxrwx.
im having trouble developing using chrome as my preview browser, it doesnt seem to update changes regularly- im assuming its some sort of cookie issue because it seems to update properly when using incognito for previewing.
when i update content on the rss, it takes like half an hour for the application to realize the rss has been updated.
if you go to the path of the rss it shows the updated information, but the application refuses to load new data for a long [email protected]: The user has a browser preference that tells his RSS feed how often to update (every 30 minutes by default in Safari).
AFAIK, you cannot over-ride that but you can change it for your own browser, although 30 minutes is the smallest interval in Safari.
(Safari & Chrome are both Webkit) Can't be cookies...
