I had this same problem for about a month.
Today I had the idea to disable the image blocker extension that I had installed for Chrome. Drive started working again immediately. I wish I had realized this earlier!
I am afraid you need to switch (just for editing your docs) to Google Chrome.
As per the documentation found here :
"Offline access is only available in the Google Chrome browser."
Once on Chrome, under the corresponding settings, you can enable offline editing per file:
OR for all files:
You can bookmark more than just pages that are live on the World Wide Web.
I also expect offline access would be useful if you can reach the Web but can't reach Delicious.
Yes, it was a bug. As stated on the Google product forum,
The issue should now be fixed. Please clear your browser's cache and cookies. If the problem still persists, kindly confirm whether, in Chrome Extensions, you have Gmail Offline enabled or not.
YouTube's premium service, YouTube Red, allows this in the YouTube, YouTube Music, and YouTube Gaming apps.
Once you are subscribed to YouTube Red ($1.99/month), you will see an "Add to offline" button below videos, this will allow you to download the video at your selected quality so that it can be viewed offline.

I found it beneficial to investigate whether or not the computer's security software is a factor. For me, Kaspersky automatically updated in such a way that inhibited my ability to edit in Google Docs. It was the result of an 'encrypted connection scanning' issue.

As of July 2015, (question asked back in 2011) you still (!) can't do much offline beyond see lists of cards, but:
The Android app now (since 27th May 2015) has "Offline Support" in its "Working on" section (with a whopping 3122 votes - follow the link to vote and encourage them on). But don't get your hopes up, because here is what they say about it:
Turns out it's some kind of freaky timing thing.
Basically even though I have told google drive "sync: allow offline" and that doc says it's "ready for offline" google drive doesn't actually allow for the "fresh tab open of an offline doc" for it. For awhile.
After you first choose the setting sync checkbox, you have to wait......
Open local files and convert them to Google Docs editors format it's not supported.

If you aren't connected to a Wi-Fi or mobile network, you can still
view and edit files, including:
This is due to the user being logged in with multiple accounts (which can be checked by clicking on the user profile picture icon on the top right corner of Google Drive). By being signed in with multiple accounts, Google Drive would be clueless about which account to use when accessing https://docs.google.com/offline/optin?json=1.
One simple workaround is ...
Had the same problem, found the solution here :
It's this little switch that caused the whole "Offline" problem (in the parameters of Google Docs here but can be in any Google app) :
It was on, an the moment I switched it off, everything came back.
Google is releasing this feature slowly to individual channels currently. The larger more active channels will get it first. All Vevo and music based ones should be already offline, but they could miss a few non Vevo or Indie ones.
I had this problem with Firefox.
I did this: Tools → options → security
I had Warn me when sites try to install add ons checked.
I added an exception for 0.docs.google.com and now it seems to be working ok (for now).
As of January 27 2017, the Trello app for iOS and Android now works offline natively.
Different locales are seeing this roll out in a staggered manner but it should be available to you soon if it isn't already.
