Please Update for FF35+ !!! Rated 4 out of 5 stars

This is an essential add-on to my collection and needs updated asap please. A great add-on, but NO support since v1.06Pre9! Be nice to find add-ons that were either maintained regularly or Mozilla finds a way to automatically update add-ons for compatibility. I suppose that's easier said than done, but I hate chasing around replacement add-ons when a developer has one that's popular and doesn't support it. Please UPDATE ASAP!

This review is for a previous version of the add-on (1.6pre9.1-signed.1-signed). 

I'm sorry but I don't plan on supporting Australis. If you can, please try the Pale Moon browser instead.

Hi BigThunder1,

Thank you for your feedback and support! It is greatly appreciated! Unfortunately, due to my real life priorities I do not have the time to devote to keeping up with all the changes in Australis. For a long time now my browser of choice has been Pale Moon (a well-maintained and saner fork of Firefox) and the add-on still works on the latest version of that browser (PM 25.2.1). Pale Moon retained compatibility at FF 24 (for better or worse, no Australis!) but still imports bug fixes and core features from mainline firefox. Newer add-ons (those that started development after Australis was released) may give you problems but some developers try to fork (or freeze) popular add-ons. If you can, I recommend you give Pale Moon a try. If you do, be sure to install the tab groups add-on listed below. All of this information has been updated on this add-on's main page. I'm sorry I can't be of more help at this time and I hope you find an adequate solution!

OUTSTANDING !!! Rated 5 out of 5 stars

Thank you STUX for reviving this add-on. By far the best vertical tab add-on in existence! PLEASE maintain this add-on until Ff developers figure out vertical tabs should be a built-in Ff standard option. Outstanding !!!
