# Making Tab mix plus and other firefox addons work with Firefox 3 beta

By Roy Osherove May 31, 2008 In [Tips & Tricks](https://osherove.com/blog/category/tips-tricks)

**Historical article** · Originally published May 31, 2008; technical details may be outdated.

I installed Firefox 3 beta and the addon I missed the most was [Tab Mix Plus](https://addons.mozilla.org/en-US/firefox/addon/1122) (along with [IETab](https://addons.mozilla.org/en-US/firefox/addon/1419), but that works on the beta). Here's how I was able to have Tab Mix Plus working on Firefox 3:

1) Try downloading the latest dev build of the addon [from this link](http://saber.kawaii-shoujo.net/Various/tab_mix_plus-0.3.6.0.071228.xpi).

2) If it won't install for security reasons, you can disable the security check and also disable the comparability check [as outlines here](http://lifehacker.com/355973/make-your-extensions-work-with-the-firefox-3-beta).

3) If all else fails, you can install the firefox [nightly tester tools](https://addons.mozilla.org/en-US/firefox/addon/6543) addon, which will allow you to force compatibility of all non compatible extensions. if Firefox won't startup and crash , start it up in safe mode (in the start menu you'll have a firefox safe mode shortcut) and disable all addons. then enable only those who don't cause the the crash.
