FF 29 broke MANY addons. Most of the addon authors with time will fix them, and make them 29 compatable, but there will be addons the can't be fixed due to the new UI, and will simply be left behind.

Your best bet is to downgrade your firefox and disable updates until all your addons are compatible with the new release.

Removed link to 28

• Awesome Screenshot Plus and Undo Closed Tab buttons are compatible with 29.

If you are having problems with add-ons you would have to contact the developer of that since it's up to the developer to provide support for their add-ons.

Awesome Screenshot Plus's dev can be contacted by e-mail or through his site

Undo Closed Tab buttons's dev can be contacted the same ways:

Tip: The Undo Closed Tabs Button add-on is actually a built in feature of Firefox. If you accidentaly close a tab, you can reopen it by pressing CTRL + SHIFT + T

It's not recommended to downgrade simply due to add-on problems. Most add-ons are updated quickly when a new version of Firefox is released. If you do want to downgrade to 28 feel free to use old unsupported and insecure versions of Firefox. Please however remember that puts your System and personal data at an increased risk. You may then wish to mitigate that by having well rehearsed bare metal restore strategies or using a virtual machine.

I've removed your link as it's not recommended to downgrade simply due to add-ons as they'll be missing security patches and also becuase users can find the link on their own if they truly wish to downgrade.

Now seeing the "Top 10 Contributor" and "Moderator" after your name Mr.Moses I can think that you are expert at FF. My question is how much time it is gonna take to fix these firefox issue?

In addition I wanna say that most of the user reviews of Awesome Screenshot Plus says that it is not compatible with FF 29

Removed ESR link. -m
