You might not know about Firefox smart bookmarks. They let you type something into your URL bar like “twisted 2345” and have Firefox load the Twisted bug page for bug #2345. Lifehacker explains how to create them.
Here’s one to add for Launchpad branches:
Once you’ve added this, you can type ‘lp twisted’ or ‘lp python’ into your Firefox location bar and get redirected to the branch page for Firefox. Anything that works as part of an lp: URL will work here. Right now, this only works on edge.
Update:Firefox escapes any slashes you put into the URL bar, which makes this much less useful.
