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.
it's an must-have addon for PaleMoon users to install some addons which says they'r not working (f.e.behind the asterisks).
Nice! Just what I need for Pale Moon!! Thanks a lot!
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.
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
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.
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.
Just need to be careful it's not enabling an extension that will give problems
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!!
Works as advertised. Simply amazing!
doesn't work 27.0.1
Doesn't work in 29.0a2
Thanks, it works as described. I found a manual way to disable it on Google, but this is much better than that.
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...
This extension helped me reinstall Tidy Read on Firefox 25.0. As yet, I have no problems.
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!
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.
Excellent work, the add-on works perfectly as desired and saves effort.
Works like it should.
Useful and workable add-on in palemoon 20.2.1
