Update Discarded Tab On Select od kgersen

This extension is equivalent to pressing Reload (F5) on a loaded tab. Cached content may be used to display the page. This is not the same as pressing Ctrl+F5, which will bypass the cache and download all the web page content again.

This extension only works on discarded tabs with http(s) URLs.

Only the web page that is displayed when the tab is selected is updated, not web pages that are accessible through the forward or back buttons.

This extension can be toggled on or off by clicking its toolbar button. Options are available by right clicking the toolbar button.

Issues

If 'browser.sessionstore.restore_pinned_tabs_on_demand' is set to true in the about:config page, Firefox will not show pinned tabs as discarded tabs to an extension after a Firefox restart.

When last tested with Firefox 91alpha, after reloading a tab and then selecting a discarded tab with the same URL, I had to wait roughly 30 seconds after reloading before selecting the discarded tab to make it display new content.
