Mozilla Firefox has a very nice feature built inside that can tell you if your installed copy of Firefox browser is taking too much time to start. This unwanted delay in browser startup could be due to some of the plugins or extensions that you have installed in the Firefox. When Firefox determines that it is taking too long to startup, it will show a notification near the bottom of the window telling you that – “Mozilla Firefox seems… slow… to start”. And you have two options – you can either choose to learn about why the browser might be slow and how you can speed it up, or you can disable the notification from being shown up in the future.
If you choose to disable this notification then it will never show again. This could prevent you from taking the benefit of the helpful suggestions shown by Firefox and make your browser perform better if you decide to follow these helpful tips.
So if you want to re-enable the slow-startup notifications in Firefox, then you can do this:
- Type about:config in the Firefox web browser and press Enter. You will see a warning about voiding your warranty, but you can just click on the I’ll be careful, I promise button and continue.
- In the search field of the advanced settings manager, type slow to narrow down the settings that we are looking for.
- Locate a setting named browser.slowStartup.notificationDisabled, right-click on it and choose Toggle from the the menu that shows up. This should change the setting value to true.
- Restart Firefox browser and see if your browser is still taking too much time to startup.
Some things, like the Slow Startup Notification, in Firefox might look annoying at first, but they are actually very helpful in improving the performance of the browser.
