Do you have smooth internet connection? The problem lies with your internet connection instead of our site.

Can you please forward the email in question to info@diigo.com so that we can
try our best to troubleshoot scenarios?

You can replace tag "Delicious" with "Diigo" on the following webpage.

1) I have managed to upload 2 pictures from an online article. I would have liked to upload all 4 of them. But after the second I got the message, that the upload function was restricted to the Diigo premium service. How does ths work?

It is an advanced function that require a lot more resources to support, so we do need to take that into consideration and set it as a premium feature.
Detailed information about subscriptions for different schemes is in the tablet.
FYI,http://www.diigo.com/premium

2) I would also like to know how to delete an uploaded picture.

Please go to your library->items->images,you can delete your images there.

Don't worry.I am looking into this issue.

Sorry for any inconvenience you met with.
We have resolved this issue. Please check it again.

Please go to the toolbar options and you can customize keyboard shortcuts in the miscellaneous menu.

Currently we do not support sharing via tags.
The workaround is to build up a list &look out for the permalink and share the link to the designated group.
What do you think of supporting the list interface of group? To put it in another way,show lists from members in
a new tab or a stand-alone section.

We have a set of projects for Firefox undergoing.Some similar extensions have been released.

As you know,we have tried hard to keep pushing ourselves forward. We are continuously optimizing our apps. Welcome to post any suggestions on how to improve FF add-ons/apps to "uservoice". Adjustments and improvements will be made to them based on votes and inputs from users.
We'd like to roll out products which can be adapted to platforms as much as possible.Meanwhile,we have limited bandwidth.We have to focus on some tasks scheduled with higher priority.
As for the IOS, we will get similar apps started immediately when we have handled issues on the top of our project list.Please stay tuned.

Having tested just now, the bookmark window is automatically closed after clicking on the save button.
Are things all well now?If the problem persists,can you please send us the problematic URL and some screenshots so that we can handle it ASAP?

It is a weird issue and no one has ever reported this kind of problem.How many add-ons do you have?
If you have a few add-ons, can you please disable some to test whether this issue was due to the incompatibility
caused by 3rd-party add-ons?
If you have too many add-ons,do you mind send your firefox profile to info@diigo.com so that we can handle it ASAP?
You can access the profile folder by the following address
C:\Users\your user name\AppData\Roaming\Mozilla\Firefox\Profiles.

We have fixed this bug.Please upgrade your diigo toolbar to the latest version.

>>>Our group setting does have "List this group in the search results" turned on.
The setting is not effective immediately.It may have some delay.

We have fixed this issue.Please check it.

Are things all well now?
What is the version of your toolbar? Please send some screenshots to info@diigo.com so that we can handle
it ASAP.

I am looking into this issue.

Having checked in database,I found that the file you uploaded is an empty file,which contains no bookmarks.
Can you please try to export from delicious again?

Thanks for Graham Perrin sharing the tip.
Annotations on webpages in based on the data transmission of mixed contents.
Please rest assured the process is safe and diigo is also a trustworthy site.
We are trying to help out with other solutions.
The alternative method is choosing "don't show annotations" from the drop down menu of diigo icon.
How do you think about it?

Currently we do not offer this kind of feature.
The workaround is to create a list and you can share bookmarks to the list while bookmarking.
BTW,you can also vote and contribute to this thread.

Sure.that would be nice and noted.
At this point, it should be part of the overall optimization of "my library".
It has been added to our to-do list but scheduled with lower priority.

We have removed you from your own followers.It is a design flaw and we will fix it to avoid this kind of issues.

Please look at the export file from delicious and check out whether it contains bookmarks.
The problem maybe was due to empty file.

We have solved this issue. Please check it again.

>>>>>1) Why would a tag I haven't used in 4 years show up under "Recent Tags"
Can you please give us the problematic tag so that we can figure it out ASAP?
>>>>>2) Why would the number of tags next to a recent tag be inaccurate? My Library under "Recent Tags" lists "usability" as having 21 items when I have 152 bookmarks tagged with usability.
The number of recent tags not means the total number of bookmarks associated with that tag. It means how many
times it has been used for your recent 100 bookmarks.

Please click the diigo icon on diigo toolbar, mouse over "see all annotations" and choose "see only private annotations" from the secondary menu. In this way,you can hide public annotations for all pages.
