My tech support tickets have always been responded to by the same person, so I don't think there's a lot of depth to Diigo's tech support, which is somewhat of a concern...

If you're trying to economise on browser real estate, there's also multi-purpose save/share tools such as Shareaholic, which supports Diigo/Diigolet:

Shareaholic - The best browser add-on extension to share, tweet, bookmark, save and e-mail web pages quickly

@fishead, agreed, I also prefer the "full" Diigo toolbar to other options.

I heartily agree! Tags should be case-insensitive, i.e. upper and lower-case should be treated as the same letter.

Good luck! It's a pity Diigo doesn't implement a proper help desk solution such as Get Satisfaction, Kampyle or UserVoice, instead of relying on this forum and/or a support e-mail address.

I'm not sure I follow. If you go to Tools, Add-ons, Extensions you can see the Diigo Toolbar version, as well as whether a later version is available (but see also my earlier post, link below).

OK, yes, I see what you mean. If there's an official representative from Diigo around, I think this should be included on the "wishlist" for the next release.

If anyone on the Diigo support team wants to see what this Topic refers to, please see the screen dumps here:

According to your Website at http://www.diigo.com/tools, the latest version of the Diigo Toolbar available for download is Version: 4.1.0.18.
When you click on Install Diigo Toolbar, however, it installs Version 4.1.0.14!
When you carry out a Find Updates from the Firefox Add-Ons window, it says that "Version 4.1.0.18 is available."
When you attempt to install the update, however, it generates the following error message:
Firefox could not install the file at
http://www.diigo.com/diigoresources/downloads/diigotoolbar-firefox-new.xpi
because: Invalid file hash (possible download corruption)
-261
This is a brand new installation of Windows XP/SP3, Firefox and Diigo.

Thanks Terry. I guess everything works better with a Mac! :-)

My explanation of the issue seems to have caused some confusion. I've summarised it in bullet point form below:

- This relates to a brand new, squeaky clean install of XP and Firefox, will all add-ons being loaded from scratch.
- On the Website at http://www.diigo.com/tools, it says that the latest version of the Diigo Toolbar available for download is Version 4.1.0.18.
- When you click on Install Diigo Toolbar, however, it installs Version 4.1.0.14!
- When you carry out a Find Updates from the Firefox Add-Ons window, it says that "Version 4.1.0.18 is available."
- When you attempt to install the update, however, it generates the following error message:

Firefox could not install the file at http://www.diigo.com/diigoresources/downloads/diigotoolbar-firefox-new.xpi because: Invalid file hash (possible download corruption) -261

So, is Version 4.1.0.18 the latest version and, given these issues, how do I go about upgrading from Version 4.1.0.14?
Also, why does the Website refer to x.18, but then install x.14?

I think this would be an expensive feature (in terms of storage) to implement as a default option. I'm quite happy to check the box if there's specific pages I'd like to snapshot.

Thanks for the feedback, yuppi c. I'll give it a try without the question mark, else use the _ as you suggested. I'm "backing up" my bookmarks from Diigo to Delicious.com, and I see the underscore being used there.
