A must for me... Betygsatt 5 utav 5 stjärnor

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 Betygsatt 5 utav 5 stjärnor

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

Many tried who promised ... Betygsatt 5 utav 5 stjärnor

... 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.

This extension help me to activate theme for new version of firefox 42 Betygsatt 5 utav 5 stjärnor

A good ectension

Still works fine in FF40 Betygsatt 5 utav 5 stjärnor

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.

Great for Pale Moon Betygsatt 5 utav 5 stjärnor

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.

Extreme helpful for the world-beating and not australis-contaminated PALE MOON Browser Betygsatt 5 utav 5 stjärnor

Thanks, due to this add-on I could install several add-ons in Pale Moon which were wrongly rejected before. :-D
And it DOES SHOW up in the add-on window but under the name "checkCompatibilty 1.3" :-p

got green cats back Betygsatt 5 utav 5 stjärnor

excellent add on. but does not show up in add on window. got my red cats green flavor back after an eternity of constant updates coupled with incompatibility notices. thanks i have my kitties back :). much easier on the eyes.

Worx way better than the 'nightly' tweak Betygsatt 5 utav 5 stjärnor

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 Betygsatt 5 utav 5 stjärnor

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 Betygsatt 5 utav 5 stjärnor

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

I can´t install it???!!!! Betygsatt 1 utav 5 stjärnor

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!!!!

Betygsatt 5 utav 5 stjärnor

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