The user who wrote the reviews as IMHO an idiot (almost!). The developer took his time and gave a considered reply Solving the reviewers problems. And why I am writing this is becasue he did not even have the manners to thank for the reponse. I hope most things get screwed up for him/her. We need better standards on the web. Feel free to repond to me offline. Dont know if poss from this site.

"Use comma between entries when copying the list of extensions (#195)"

You just screwed this up big time. Without the commas, I could add the list of extensions into an Excel spreadsheet. I used the spreadsheet to compare my various profiles across my computers.

Now, because you made this change after all the YEARS that NTT has been around, I now have to work around this if I am going to maintain my spreadsheet.

I’m guessing you never stopped to consider how this change was going to affect those of us who have been using NTT all these years before acting on it. Thanks a lot.

Reply: Incorrect! All I needed to do prior to this change was Ctrl+V to paste the list of extensions into Excel.

I do not import which is what you are talking about. I pasted. I can't do that now because the entire list goes in one (1) cell rendering things worthless.

Again, you failed to consider the unintended consequences of this change before making it.

Leider funktioniert dieses bisher sehr gute AddOn ab Firefox V. 48.x nicht mehr!
Ursache ist die Modifizierung von Firefox betreffend Richtlinien in Sachen AddOns.

Abhilfe gibt es keine, außer sich nach aktuellen oder ähnlichen AddOns umzusehen, welche man nicht mittels
"Nightly Tester Tools" freischalten muß.
Man kann somit getrost unter Firefox 48.x "Nightly Tester Tools" deaktivieren, oder gleich deinstallieren.

The option to disable addon compatibility checking does not work in Firefox 48.

Good way to force the installation of incompatible extensions.

Hi,
All the features seems awesome but I can't manage to find them anywhere. No menu under the main menu, neither under Tools menu and no options button in face of the add-on in the manager so I don't know how to configure it.
I'm using Pale Moon 25.2.1 (x86) under windows 7.
Thanks again.

Had no icon or features for ghostery until I used this addon
Thanks

I just use this extension to disable extension capability checking. I'm sure it's more powerful than that, but it does what I need and it light and simple. 5 star.

OK, thank you for answering.

Like I said, I have tested your add-on for a few weeks with different add-ons and browser crashes. After first install, I had some problems but I think it was my fault because I didn't know how to use your add-on properly. I had only two times Firefox crashes (Aurora). I HAD before installed your add-on very often crashes (especially when Firefox reached 700 MB to 1,5 GB memory usage). I think that your add-on helped to make Firefox more stable?

I will use Nightly Tester Tools. I'll report if I've issues. For now, it works great. 5 stars for your add-on.

Indispensavel

I was hoping that NTT's title-bar editor would do what I want, but it doesn't, so probably the only feature I'll really use (not actually being a nightly tester, just beta) is the "force compatibility" tool, in order not to keep losing add-ons every time I update to a new Beta release number. The other tools do look useful for people who really are living on the Firefox edge.

What I was *hoping* the title-bar editor might do was allow me to customize the title *individually* for each of my open windows. I've lately been trying to use separate windows to group related tabs (e.g. a "social" window for Facebook and LinkedIn tabs, a "work" window for things I'm currently researching for work, etc.). I often have several hundred tabs open (lots of "I'll get back to that"s that never happen...) but it's hard to keep track of what's where when each window just shows the title of the current web page. And no, Firefox's own "tab groups" feature won't do what I want, and I hate, hate, hate that interface. (Clustering *actual* tabs or expand/collapse *actual* tabs would be the way to go -- not a gazillion thumbnails.)

UPDATE -- 25 Feb 2013: Loss of 1 star, from 4 to 3.

I just had my first occasion to try using the "Force Addon Compatibility" feature, when FF updated itself from Version 19 to Version 20 Beta 1. (Does anyone else find it absurd that we're up to "FF 20" with essentially the same product as FF 7? Or is it FF 5?) As a result of the update, my "Tab Utillities" add-on was disabled as being "incompatible".

I saw a warning about the Tab Utilities add-on before I actually applied the update, so I turned on "Force Compatibility" before updating FF. No joy -- the add-on was still disabled after the update. So I turned off the Force Compatibility, then turned it back on and accepted a re-start. Still no joy, the add-on continues to show as disabled. So, as far as I can tell, the Force Addon Compatibility feature doesn't work. Since that's the only feature I was expecting to use, I've deducted one star.

What does work (sort of), in place of NTT, is the trick COKEDUDE posted below, updated. I added

extensions.checkCompatibility.20.0 FALSE

to about:config. Now I can fiddle with Tab Utilities options, but it doesn't seem like Tab Utilities actually WORKS even with that new Config line.

(As a feature request for more serious testers than me, I wonder if forced compatibility could be managed on a per-add-on basis. Someone doing serious testing might want to activate just one "incompatible" add-on at a time to see if they actually work.)

I found out why. About:config is missing this line. Set it to false
extensions.checkCompatibility.17.0

Then install whatever you want.

I love this addon! BUT.....I don't seem to be able to get it to work in Firefox 16.0.2 running on Ubuntu 11.10 :-(

Great for Titlebar text, 5 stars

Fantastic little addon!! .... Is there somewhere I can download it and save it to my PC in case Firefox outdates it lol

To force addon compatibility in Firefox 8 you must have to:

Type about:config in Firefox addressbar and press Enter. It'll confirm, click on "I'll be careful, I promise!" button. Now right-click and select "New", then "Boolean". Give it name:

extensions.checkCompatibility.8.0

And set it's value to false. That's all.

This is the same thing that NTT does with your browser, but it always changes the version number automatically to match the browser's version. That's why I gave it five stars.

What they said, not compatible with Firefox 8. Tried to find your e-mail, but to no avail.

Same here, not working anymore. Plsssss!

Force addon compatibility is not work with FF8.

Firefox 3.6.23 on Solaris 10 SPARC system

I agree with QueenOfStars writing on August 24, 2011

"the version numbering is off; you went from 3.1.7 back to 3.1.5.1 and it doesn't auto-update anymore."

The "make compatible" button no longer displays on the Add-ons menu and Force Addon Compatibility option from the Tools->Nightly Tester Tools menu does nothing.

Is there a plan to fix this and when will this be updated for Firefox 7?

Estaba buscando ésta funcionalidad desde hace rato porque detesto cuando mis extensiones se desactivan con cada cambio de versión de Firefox. Gracias por compartir ésta funcionalidad.

Now that mrtech tools add-on is dead, this is a must have.
Guys, the version numbering is off; you went from 3.1.7 back to 3.1.5.1 and it doesn't auto-update anymore.

Excellent add-on for Firefox. If it wasn't for this little program some of my other add-ons wouldn't work due to compatibility issues. Keep up the good work!

Forcing Add-on compatibility does not work on Aurora 8.0a2, so none of my Add-ons can be enabled.
