Deeply needed... Noté 5 sur 5 étoiles

...and working well.Thanks.

For all the addons testers, a must have Noté 5 sur 5 étoiles

It allows to install incompatible addon. You can do it though the about:config, but this extension is genious. Why is it genious? Because Firefox keep changing the about:config parameter each time it updates, and ask to enter the current version, so no more headache with this.

loving it! Noté 5 sur 5 étoiles

works on ff version 53!

Excellent Noté 4 sur 5 étoiles

This add-on working awesome,Thanks for adding!

It worked fine in an old Firefox12 Noté 4 sur 5 étoiles

A very basic addon which is more user friendly than manually use about:config and set checkCompatibility to false

tnx Noté 5 sur 5 étoiles

Working flawlessly with v49

in last FF doesn't work Noté 1 sur 5 étoiles

in last FF doesn't work

Does not work in Firefox48 Noté 3 sur 5 étoiles

This Addon seems to be enable, but it isn't functioning actually.

Does Not Work In Firefox 48.0 Noté 1 sur 5 étoiles

Just... does not work in 48. At all. Sits there in the Add-ons Manager right next to compatibility-disabled extensions with no effect on them whatsoever.

Worked Flawlessly Noté 5 sur 5 étoiles

This was exactly what I needed to reactivate some old, yet still functional, addons.

Plug disappeared and won't reinstalled Noté 5 sur 5 étoiles

When I upgraded to Firefox 47, this plugin, which had been installed, disappeared from my add-ons. When I tried to reinstall it, it said it installed, but never shows up on my add-ons.

Changes within Firefox are afoot Noté 5 sur 5 étoiles

While this extension may do what it does just fine, Mozilla has changed their code to require plug-ins to be "signed" before they can work. They will be marked as something that means the original writer never got the xpi registered and approved by mozilla. Recommendation is to switch to Palemoon or another fork of Firefox.

Does not work Noté 1 sur 5 étoiles

I installed this to firefox to try & stop Fast Dial being disabled by the incompatibility check (even though Fast Dial works flawlessly). Unfortunately this AddOn does not work & Fast Dial is still being disabled every time I reload firefox no matter how many times I reinstall it.

Does what it says on the tin. Noté 4 sur 5 étoiles

Lets you install addons marked as incompatible. This is great if you have a non-standard browser (like Pale Moon).
I would like to see an option to disable the incompatibility warnings in the Add-on Manager and even allow you to automatically check and install updates in the Manager. Still, it works.

A must for me... Noté 5 sur 5 étoiles

Until I get KeySnail *possibly* ported (rewritten with same functionality, but not using the code from original straight, just as reference) to the coming "new add-on api" - hopefully this api will support reading keypresses before firefox does anything to them, so can override any regular hotkeys... And there's always bound to be new add-on vs. firefox version issues, so this will be needed... currently many add-ons are incompatible with my Linux Mint 17.1 USB stick, which I boot from some systems...

So this is really needed.

Perfect Noté 5 sur 5 étoiles

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