Thank you for this wonderful tool. I love it. It made several supposedly incompatible add-ons work again, including Charamel and Silvermel themes.

... they disable the annoying and everytime frustating Compatibility Checks. And do exactly what? Right! Nothing!
But this works fine and was a relief for me. I had give up my hope an was on the way to be frustrated, but your Addon saved me and my mood.
Yet I can use many of the (for me) important addons.

Thank you.

I was concerned by the previous review saying the addon no longer works in latest version. In making a limited test of a very old addon, checkCompatability seems to do exactly what it aims to (prevent FF from disabling plugins due only to the version number).

In v40.0.3 I tested it with an arbitrary older plugin: Custom Google Search v1.1.2. I was able to install the plugin, and on restarting, the plugin's custom setup screen appeared and allowed me normal interaction (it is 6 years old, so I couldn't do a "live" test with the current google API). Upon disabling checkCompatibility, the old plugin changed from the yellow "could not be verified" message to the red "has been disabled" one. On re-starting cC, the google plugin was instantly functional again.

The nature of "incompatible" plugins makes it probably impossible to perform a conclusive test, but there is certainly not a complete loss of function due to the recent major upgrade. Sadly, it's probable that any major FF revision will alter enough code that some older plugins will become genuinely incompatible. But if that's the case, we shouldn't give checkCompatibility 1-star reviews, if it still does its job of preventing the strict disabling of plugins marked as deprecated.

It does not work in Firefox v40 now :( Is there any workaround solution? Thanks.

Had to downgrade to v39.0.3 in order to get it to work.

Excellent tool to get extensions and themes up and running in Pale Moon. I tried manually adding the entries in Pale Moon but it did not help. This extension is wonderful.

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.

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.

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!!!!

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