Opening The Preferences Dialog
You can open Thumbnail Zoom Plus’ Preferences dialog in three ways:
- In Firefox’s Add-ons Manager (“Add-ons” in the three-line menu pane), find Thumbnail Zoom Plus in the “Extensions” area and press its Preferences button.
- Click the Thumbnail Zoom Plus tool button and select “Preferences”.
- While the Thumbnail Zoom Plus pop-up is displayed, press the “p” key (without Control or Command).
The Preferences window has three tabs: General, Disabled Sites, and Site Checkboxes.
This tab has general preferences:
- Enable: Turn this off to disable Thumbnail Zoom Plus on all sites. You can also toggle this by clicking the Thumbnail Zoom Plus icon in the toolbar or by pressing ‘x’ when a pop-up is displayed. Even when Enable is off, you can see pop-ups if you hold down the configured “Key to maximize the image” (default: Shift).
- Delay before displaying (sec): Waits this long before starting to display the pop-up.
- Setting the larger prevents pop-ups when the mouse is moving to somewhere else, saving download bandwidth and power. Setting it smaller lets you see the pop-up sooner.
- Show partial image after (sec): If Firefox has loaded only part of the image after this time, displays the partial image (and the rest of the image as it loads).
- Default Zoom (%): Default zoom amount, as a percentage of the full-size image. Defaults to 144%, showing the image magnified somewhat.
- Reduce if image appears to have low quality when magnified; increase to see larger images.
- Hotkeys: Turn this off to disable Thumbnail Zoom Plus hotkeys.
- Key to [ not display / display ] the image: [ None / CTRL / SHIFT / ALT ]: When set to “[ not display ]” (the default), holding this key when moving the mouse prevents a pop-up. When set to “[ display ]”, the pop-up will not be displayed unless this key is held.
- Key to maximize the image: [ CTRL / SHIFT / ALT ]: The pop-up will be shown extra-large (200% and allowed to overlap the thumbnail) if this key is held down either when moving the mouse onto the thumbnail, or when the pop-up or “too small” indicator is shown.
- Save As Name: Selects how the “Save full-size Image As” right-click item and ‘s’ hotkey names images when saving. Choices are:
- Caption: the image’s caption text
- Web Location: the image’s filename
- Caption & Web: caption followed by filename
- Web & Caption: filename followed by caption.
- Show border: Shows a border around the pop-up. The border’s color indicate the type of pop-up:
- Green: image gallery (lighter green on the first image).
- Red: Youtube or other video.
- Blue: link’s page may have additional content besides the image.
- White: link is the same as the image with no additional content.
- Show pictures using all available space: Allows the pop-up to overlap the thumbnail or link you hovered over.
This lets the pop-up appear larger, but you won’t see the link it came from. The pop-up will disappear when you move the mouse outside the area of the original thumbnail or link, when you click the mouse, or when you press the “esc” (Escape) key. Examples — without and with “Show pictures using all available space”:
- Max size: allows the pop-up to fill the web page’s area, the entire Firefox window, or the entire screen. See the examples below.
- Show %: Shows the size of the pop-up as a percentage of the full-size image; this appears in the lower-right corner of the pop-up. It also appears in the “too small” indicator.
- Numbers less than 100% mean the pop-up is smaller than the full-size image, and you could view the image larger if your window were larger or if you pressed “t” or “w” to open it in a new tab or window.
- Numbers greater than 100% mean the image is being magnified larger than the original full-size image, so you may see compression artifacts (reduced quality).
- Show caption: Shows the thumbnail’s caption text below the pop-up. Thumbnail Zoom Plus has several rules to try to find the a good caption.
- Add to history: Adds pop-ups to the Firefox’s History.
- Useful with some sites like reddit.com because links to those images will then appear in a different color indicating they have been “visited”.
- Scrolling triggers pop-up: when on, scrolling the page under the mouse will trigger pop-ups to appear. Enabling is useful on sites which aren’t too dense with thumbnails (eg reddit.com); disabling is useful on sites with very many thumbs (eg Google Images). Defaults off.
- Pop-up takes keyboard focus: when on the pop-up takes keyboard focus from the web page so you’ll realize that typing is for the pop-up’s hotkeys, not the web page. The pop-up closes when it loses keyboard focus.
- Turn off if you’re having trouble with the pop-up closing immediately or if a web page’s pop-up menus close when the Thumbnail Zoom Plus pop-up appears (eg on certain Linux machines on in Firefox 3.6).
- Debug: turn this on to make Thumbnail Zoom Plus write messages into Firefox’s “Tools > Web Developer > Error Console”. If you have a problem with Thumbnail Zoom Plus, the developer may ask you to send a debug log as follows:
- turn on the Debug check-box;
- use Thumbnail Zoom Plus until the problem happens;
- press “Copy Log“;
- Turn off the “Debug” check-box;
- paste the result into an email to firstname.lastname@example.org .
Preferences: Disabled Sites
This tab lets you disable Thumbnail Zoom Plus when visiting particular web pages.
- The easiest way to add a page is to visit the page and press the second Add button (eg “Add http://www.reddit.com”).
- Any web page listed here will not show pop-ups.
- The entry must match the entire web address (except the http:// or https:// prefix) to disable a site.
- Use wildcards “*” to match any number of characters or “?” to match any single character.
- Note that you cannot block pop-ups based on the site the image comes from.
- To edit an entry double-click it.
Preferences: Site Checkboxes
Turning off a site’s check-box will prevent Thumbnail Zoom Plus from showing pop-ups for that site. For example, turning off the “Facebook” check-box prevents pop-ups from when viewing Facebook. This is a shortcut instead of adding a site to the Disabled Sites list.
This section includes three additional special site check-boxes:
- Others: Support for many sites other than the ones with their own check-boxes, including all sites which link directly to images (such as reddit.com).
- Others (Indirect): Additional sites other than ones with their own check-boxes. These may load a little slower since Thumbnail Zoom Plus must read and analyze the linked web page to find the images.
- Thumbnail (off by default): Shows pop-ups for the thumbnail images themselves even when there isn’t a higher-resolution image available.
- Especially useful with Shift (key to maximize image) or with Default Zoom % larger than 100%.
- Lets you see small thumbnails better without straining your eyes, but image quality may be poor.
- Disabled by default since it may cause pop-ups from buttons and other places you don’t want them.
