Users who use uBlock Origin and try to log in to RefWorks are unable to do so. (Tested in Firefox and Chrome.) The devtools console reports a TypeError regarding some tracking structures found unexpectedly undefined at login time. There are very simple ways to handle such cases gracefully in the code, and should be a simple fix for any modern website.

Right now, there is a help document at https://knowledge.exlibrisgroup.com/RefWorks/Knowledge_Articles/RefWorks_Browser_Best_Practices, to which a support representative will send users, upon request. This document explains that RefWorks does not play well with the likes of uBlock Origin, and requests that users disable these while using ProQuest and Ex Libris products.

On principle, to fix a broken product is better than to maintain a supporting document and support staff for the sole purpose of explaining away the product's brokenness. The site ought at least to present an error message, rather than silently break until the user checks the debug logs themselves. If monetization is the reason that RefWorks depends so heavily on the offending tracker code, I would much prefer the option to pay a fee, rather than disable my anti-tracking plugins.

As a web developer myself, I understand the benefit of some analytics. But a good product does not depend so fully on these analytics that the product breaks entirely when these analytics are disabled. Considering that I proactively contacted RefWorks Support regarding this issue, analytics would not have been more useful than that real communication. Anti-tracking plugins give users control over who follows their online browsing.

RefWorks is so far the only website I've found that breaks at the presence of uBlock Origin and the like since several months ago when I began using ad blockers. RefWorks may not be unique with this issue, but this behavior certainly is not the norm.

When selecting APA 6 for the RefWorks bibliography, you see a standard option and other variations.
• APA 6th - American Psychological Association, 6th Edition
• APA 6th - Annotated with Abstracts - American Psychological Association, 6th Edition
• APA 6th - Annotated with Abstracts - No Title Casing Applied - American Psychological Association, 6th Edition
• APA 6th - No Title Casing Applied - American Psychological Association, 6th Edition
• APA 6th - No Title Casing Applied, New DOI - American Psychological Association, 6th Edition

When selecting APA 7, no standard/basic option is indicated.
According to section 9.34 of the APA 7 manual, DOIs should be included with references when available. According to section 9.35 of the APA 7 manual, DOIs should presented in the following format: https://doi.org/xxxxx. There are exceptions (e.g.,when no doi is available), but these sections outline the basic standard. Thus,the default for APA 7 should be the following: APA 7th - Sentence Casing, DOI:https://.

I think it is valuable to have variations available, but most students (and many faculty and other professionals) are not going to have enough experience to identify which RefWorks APA 7 option is best. Users need to be able to determine the standard option quickly.

I propose a display of APA 7 bibliography options like the following: 
• APA 7th – APA 7th Edition Standard Formatting (SentenceCasing, DOI: https://)
• APA 7th - No Case Changes (No Title Casing), DOI: empty
• APA 7th - No Case Changes (No Title Casing), DOI: https://
• and so forth...

Thank you for considering my request.

In the Advanced search form, if a user types in a term then decides to change the search field, the text they type is erased. This leads to user frustration. I reported it to the Support Portal and go the reply that is by design not a bug. This would be a suggested improvement, if you would like to make suggestions for improving the product please add them to our forum at https://ideas.exlibrisgroup.com/forums/909445-refworks . The suggestions made here are used by the management and development team to chart future product development.
So here it is and thank you for considering it!
