I'm happy to keep my software up-to-date, but FireFox has never fixed the bug which requires it to restart every time an add-on is installed. That behavior is preposterous and unnecessary, as demonstrated by Chrome, which does not exhibit that bug: in Chrome, you can update an add-on without restarting the browser.
Furthermore, Firefox has a second bug where if I click a link from somewhere outside the browser, and my OS opens Firefox to display the link, and Firefox wants to install an add-on, if I agree to install the add-on, Firefox forgets about the link I was trying to open. This all adds up to an unsatisfactory user experience.
Luckily, and not surprisingly, this is easy to fix:
- type about:config in the location bar
- look for "app.update.interval"; the default is probably 86400, which is the number of seconds in one day
- change the value to something reasonable, such as 2678400, which is the number of seconds in a month
- look for "extensions.update.interval" and do the same
