How to use SiteDelta
- Let's start
You found an interesting page you want to watch...
Just click the black triangle (SiteDelta icon) in the Firefox status bar.What's next?
When you visit this page for the next time, the SiteDelta icon won't be black - it will be red (telling you that something changed) or green (if everything is just as it was at your last visit). If the icon is read, just click it to highlight all changes on the page. Clicking again allows you to cycle through the changes.But SiteDelta tells me that the time or a banner has changed each time
You can ignore such regions - see below.But I don't want to visit the page every day just to look whether the icon is green
That's what "auto-watch" is for. Enable it in the preferences dialog (Tools -> Add-Ons, SiteDelta, Preferences). If it is enabled, SiteDelta will periodically check all known pages for changes. If a page changed, a red documents icon will appear next to the SiteDelta icon that provides access to all changed pages.I don't want to check for changes periodically, but I want to check all pages now instead
Use the "Check all pages" entry in the SiteDelta context menu. In SiteDelta Manager you can also view and edit your list of watched pages (delete or rename entries, check for changes etc.). You'll find many functions in the page list context menu. - Defining regions
You can set regions to scan or ignore for each page.
In the SiteDelta icon's context menu you will find the entry "Regions -> Scan region" and "Regions -> Ignore region". When clicking it, you can select the desired page region by clicking it. When moving the mouse, the currently hovered element is outlined. To select a greater region containing this element, move your mouse towards the border if the element. When you click, the selected area is added to the scanned or ignored regions. If you don't click, but drag the mouse onto some text on the page, this text is used as reference to find the region in the page. This might be useful when you want to ignore a certain cell row that contains a certain word but can appear somewhere in the table or move when another row is inserted above.
The scanned and ignored regions are shown in the "Regions"-menu. When you hover their name, the regions are outlined in the document; click them to remove. - Presets
If there are multiple pages with similar structure (e.g. they are managed in a CMS or show structured data), you can create a preset for them. After setting the regions for one of the pages (using reference text to define the regions if possible), they can be saved as a preference in the page properties dialog. You can give them a name and enter the addresses this preset should be used for (you can use * and ? as wildcards). This preset will automatially be used if you visit another new page matching the given address.
