We had this question come up before with Google Scholar but the thread was left dangling, so I don't know whether this was helpful:

Poster: Clearing cookies did not stop Google Scholar links from going to the previously affiliated institution's login page.

Me: In that case, it probably is saved in your Google account. Did you check the settings page to see if it's stored there? Maybe "Library Links" in the left column? https://scholar.google.com/scholar_settings

Old thread: google scholar is chosing a proxy library and I can't find and/or delete where is setting is kept in Firefox (unsolved)

Sorry, that is not the problem. I think I need to reconfigure the browser, not set up Google Scholar (it has not library or proxy settings).

Firefox has a proxy setting, but it's not site-specific. You can check that here:

• Windows: "3-bar" menu button (or Tools menu) > Options
• Mac: "3-bar" menu button (or Firefox menu) > Preferences
• Linux: "3-bar" menu button (or Edit menu) > Preferences

In the left column, click Advanced. Then on the right side, with the "Network" mini-tab active, click the "Settings" button. The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".

Are these links you're opening ordinary http/https links or do they use a special protocol at the beginning?
