Worx way better than the 'nightly' tweak Rated 5 out of 5 stars

There R other addons 2 disable compatibility but they R flakey. This 1 actually worx =) Can use it 2 help things like 'extension list dumper' work, etc. This should B a default button in FF, not some addon we have 2 load. Just like 'about config' they can put a warning balloon on it or something. B real.

Great in SeaMonkey Rated 5 out of 5 stars

Works perfectly with no hassles or config needed — good thing, because I doubt I would've lasted more than a month in SeaMonkey if I'd had to manually edit every outdated extension I wanted to try out.

Working great Rated 5 out of 5 stars

Just need to be careful it's not enabling an extension that will give problems

I can´t install it???!!!! Rated 1 out of 5 stars

I think that could be a very good add-on, but i can´t say anything about this, because my FF (FF 28) says that it´s not compartible with my FF-version, but on the add-on site there´s no warning about this and the FF-help was not usefull, too! Please help me!!!!

It works on Firefox28. One of the best add-on ever. I can use my old favorite add-ons again. Thanks!!

Thanks, it works as described. I found a manual way to disable it on Google, but this is much better than that.

excellent add-on Rated 5 out of 5 stars

when all the other add-ons failed, this was the only one that worked to revive privacy suite on my computer...now am able to backup all my passwords before saying goodbye to the awesome extension...

Thank you! Rated 5 out of 5 stars

This extension helped me reinstall Tidy Read on Firefox 25.0. As yet, I have no problems.

not working in daily etc Rated 4 out of 5 stars

still a good idea but TB seems to have changed the names of the compatibility check keys in about:config - I managed to switch off by going in a toggling also the keys with "saved" in them...this could be a drag to do for every daily update though!

Please update - broken in TB24 Rated 5 out of 5 stars

The five star rating is for how this add-on used to work. I consider this one ESSENTIAL, given the rapid-fire updates these days. Please update for TB24 and above!! I miss the extensions I had working until TB updated itself...

Thanks for this! It made me able to install discontinued add-ons.

Useful and workable add-on in palemoon 20.2.1

Works perfectly with all but very old add-ons Rated 4 out of 5 stars

This add-on works precisely as advertized. Has allowed me to use several add-ons which this website claims are incompatible with FF v22, and which FF will otherwise refuse to install. Requires no setup and has no options, but simply disables this check.

I would have given a full five stars without hesitation, if not for a few minor issues:

* In the add-on list, it is titled "checkCompatibility," which is badly formatted and confusing because it's the opposite of what the add-on actually does. Something more like the title on this page ("Disable Add-on Compatibility Checks") would be much more appropriate.

* Description is confusing, mentioning the variable name many times while only indirectly stating the primary function of disabling the check, and what this will allow in practice.

* If disabled or removed, the add-ons it facilitated will also be disabled at the next restart. This should be mentioned somewhere in the description or upon disabling, since one might reasonably assume this add-on is no longer needed after the compatibility is confirmed during installation.


I consider this add-on to provide critical functionality which should be included in FF itself, especially considering the frequency of its revision releases and the fact that most newer addons will still function perfectly. Until mozilla allows us to perform "experimental" installations again, this add-on works beautifully. Thanks so much!
