At work, we use a bug-tracking system to keep track of what work needs to be done. I can set the new tab page to be a list of all of my bugs, however this page loads slowly, as the site queries a database to get the list.
I would like Firefox to open a cached version of this page every time I open a new tab, so that it loads faster. If I wanted an up-to-date version of the page, ideally I would just be able to click refresh. Does this functionality exist, either in Firefox itself or in an add-on?
I tried changing the
browser.newtab.preload value in about:config to true, but this does something very different from what I want. It simply opens a blank page first then swaps in the home page once it's done loading. I want to see the webpage instantly.
