Here are a few quick tips to optimize Firefox and Thunderbird, based on questions we’ve been asked recently.

Firefox

Firefox is using Yahoo instead of Google to search.

Recent Firefox updates force a change of the default search engine from Google to Yahoo, which a lot of people find annoying. To switch the default back to Google (or your favorite):

1. Click on the magnifying glass in the search box on the upper right of your Firefox browser window.
2. Select “Change Search Settings” at the bottom of the list.
3. Select your Default Search Engine as desired.
4. Close the preferences page and you’re all set.

Firefox gets hung up when I use Web UI.

The most recent version of Firefox (41.x) is incompatible with Web UI. We suggest rolling back to a previous version of Firefox, version 38. We particularly like the Extended Support Release (ESR) version because it doesn’t get updated as frequently as the general release. Go to https://www.mozilla.org/en-US/firefox/organizations/all/ and download and install the appropriate version of it.

Firefox tells me there’s an update but it doesn’t successfully install it.
You can always update Firefox manually. Follow the instructions above for downloading the latest ESR version. (If you prefer to have the latest version, which may have incompatibilities with various web programs, you can get it at https://mozilla.org .)

When I try to drag Firefox into my Applications folder on my Mac it tells me I don’t have the right privileges.

1. Download the new version of Firefox.
2. Quit Firefox.
3. Open up your Applications folder, and drag Firefox to the trash. Don’t worry, it will still have your settings, history, and bookmarks.
4. Drag the new Firefox icon into your Applications folder.

Firefox doesn’t display PDF’s correctly.

Firefox has a built-in PDF viewer, and there are also add-on PDF viewers for Firefox. The add-ons tend to get out of date as Firefox is updated, which can cause problems. We recommend that you disable any add-ons, and then either use Firefox’s built-in viewer or choose to open PDF’s in a separate application, like Adobe Acrobat, Adobe Reader, or the Mac’s Preview.

To disable add-ons:

1. From the Menu button (three horizontal lines over on the top right side of the window), select “Add-ons.”
2. With “Extensions” selected on the left, scan for any “PDF” or “Adobe Acrobat” or “NPAPI” listings, and disable any you find.
3. Select “Plug-ins” on the left, and again look for anything labeled with “PDF” or “Adobe Acrobat,” and if you find any set them to “Never Activate.”
4. Close up the Add-on tab.

To choose whether Firefox uses its built-in PDF viewer or another application:

1. From the Menu button (three horizontal lines over on the top right side of the window), select “Preferences.”
2. Select “Applications” from the panel on the left.
3. Scroll down to find “Portable Document Format” or “PDF” in the “Content Type” column, and select it.
4. In the “Action” column choose “Preview in Firefox” or select another application to open PDF’s.
5. Look for any other instances of “Portable Document Format” or “PDF” in the “Content Type” column, and change as desired.
6. Once you’ve changed all instances close up the Preferences tab and you’re all set.

Thunderbird

Thunderbird tells me there’s an update but it doesn’t successfully install it.

You can always update Thunderbird manually by going to https://www.mozilla.org/en-US/thunderbird/ and downloading and installing the latest version.

When I try to drag Thunderbird into my Applications folder on my Mac it tells me I don’t have the right privileges.

1. Download the new version of Thunderbird.
2. Quit Thunderbird.
3. Open up your Applications folder, and drag Thunderbird to the trash. Don’t worry, it will still have your email and settings.
4. Drag the new Thunderbird icon into your Applications folder.

While I’m typing, every once in a while Thunderbird pauses and doesn’t keep up with my typing.

A recent update to Thunderbird includes the Lightning Calendar add-on. If you set this up to sync with an online calendar you may notice these symptoms. In that case we recommend turning off the Lightning calendar functionality (or you could just disable the online calendar). To turn off Lightning:

1. From the Menu button (three horizontal lines over on the top right side of the window), select “Add-ons.”
2. Find “Lightning” and click “Disable” or “Remove.”
3. Close the Add-ons Manager tab. You may have to quit Thunderbird and start it again to actually get rid of Lightning.

To remove a synced calendar without removing or disabling Lightning:

Lightning requires at least one calendar, so if you only currently have one calendar you must add another before you can sync it. To do this:

1. Select “Calendar” from the “Events & Tasks” menu.
2. Right-click (or Control-click on a Mac) on the calendar pane and select “New Calendar.”
3. Choose “On my Computer” and click “Next.”
4. Give the calendar a name and create it.
5. Now that you’ve got at least one calendar besides the one you’re deleting, you can right-click click (or Control-click on a Mac) on the calendar you want to delete and choose “Delete.”

The DC is located on the third floor of the Library, turn right as you step out of the elevator, then a quick left & it’s on your left. The direct telephone number is 413-559-6602. Before you bring in your computer, please know a few things:

• We are normally open from 9 a.m. to 5:00 p.m., Monday – Friday (we’re just getting up to speed for the semester, so the hours might be a little quirky). If the door is closed during working hours try knocking anyway, and a staff member might be able to help. You cannot pick up or drop off your computer any time other than within these hours, so you probably shouldn’t bring in your computer at 4:30 p.m. on a Friday evening unless you don’t mind it sitting in our office all weekend.
• If you have a laptop computer, please bring the power supply for your laptop.
• If you have a desktop computer, we do not need you to bring any cables at all. Just bring in your tower. We have a hand cart that you can borrow as long as you leave us ID.
• Make sure you have all the disks that came with your computer and software. If we need to reinstall your operating system, we need to have the install disks to reinstall software.
• Check your warranty information. Remember, we cannot fix some computer problems when the computer is still under warranty.

You can contact the SDC at dc@hampshire.edu, or give them a call at 413-559-6602.
