简介
This extension only monitors other add-ons of type 'extension' (not theme, etc...) and installType 'normal'.
The 'Access your data for all websites' permission allows this extension to fetch the updateUrl of extensions that are self-hosted (they are not on addons.mozilla.org) to get their current versions. This permission may be granted in the Options page. Alternatively, permissions may be individually granted for each self-hosted extension to avoid using the 'Access your data for all websites' permission. A user will then need to manually grant permission in the Options page each time a new self-hosted extension is installed. If this extension has not been granted permission to fetch the updateUrl of a self-hosted extension, then that extension will be ignored.
A button badge will appear on this extensions toolbar button if there are available updates. The toolbar buttons popup will show which extensions have available updates. Also, notifications may be turned on to notify a user.
By default, clicking on the toolbar button will open the popup. Right clicking the toolbar button will open a menu that allows a user to check for updates, open the Options page, or view a log of recent updates. Update check frequency, toolbar button actions and colors, notifications, etc... are configurable in this extensions Options page.
If the option 'Save a log of recently updated, installed, and uninstalled extensions' is selected, the file dexie.js ( https://unpkg.com/dexie@4.0.8/dist/dexie.js ) will be used. It is also used if opening this extensions page to view a log of recent updates. Dexie.js is a wrapper library for indexedDB - the standard database in the browser. Here is its GitHub link: ( https://github.com/dexie/Dexie.js ). Here is its homepage link: ( https://dexie.org/ ).
Issues/Limitations
* The option 'Save a log of recently updated...extensions' may not work if 'Never remember history' is selected (Settings - Privacy & Security - History).
* This extension can't force the browser to check for updated add-ons or update add-ons that have available updates. A user may need to manually select 'Check for Updates' in the 'about:addons' page to show all the available updates.
* Some extensions delay installing an update until the browser restarts. They will continue showing an update is available until the browser restarts or until a user selects the 'Update now' button on the extension in the 'about:addons' page.
* If an extension is removed in the 'about:addons' page, an 'Undo' button will appear. If the extension has an available update, it will continue showing an update is available. The extension may be uninstalled by reloading or closing the 'about:addons' page.
