TL;DR – Blocks distracting websites to help you get stuff done.
It’s more often than not we kick-start the browser hopefully to get some serious stuff done, but end up wasting more than a couple of hours at Facebook, Twitter, etc. This is not acceptable and definitely something to cured. We, developers, need a workflow; a tool that armors us against this disease (calling it ‘disease’, jokingly!). Talking about blocking distracting websites, there are a lot of tools available. Both for PCs and Apple Mac. But guess what there is good new for Firefox users. Because we have Idderall; the tool we need. Sadly it’s not available for Chrome.

- In activated state, it cannot be deactivated or uninstalled
- It has three ways to stop you from accessing settings and unblocking the websites
- First it will make you lose money somehow if you unblock sites
- Second is an intervention from friends
- Lastly and my favorite is that it will embarrass on Facebook

Downloads – 1,088,230
TL;DR – Lets you get rid of those annoying unwanted popups
Nobody likes to get an unwanted popup, it is irritating and kills user experience! Still lots of websites display them, even authentic ones. That’s where Adblock Plus Pop-up add-on comes it, it lets you block these popups. But.. there’s a bad news! It doesn’t block popups by default that are opened upon mouse clicks or other user events.
Two ways to make this add-on work:
- Add the popup URL to Adblock Plus Pop-up filters. It will block that popup, but will display popups with different URLs.

TooManyTabs is an incredibly useful Firefox add-on for managing plenty of tabs, which a typical developer has open. If you’re anything like me, you will usually have more than 20 tabs open at a time. Each longing for attention. And they are distracting sometimes. Another difficulty is that too many tabs contract each other so much that their page title eclipses and we’re left with favicon. This results in bouncing around from tab to tab to finally find that one.
