Hi Alex,

Assuming that you are using the latest Firefox version (58.01) and that you're talking about this add-on :

https://addons.mozilla.org/en-US/firefox/addon/hidetab/

That add-on is not compatible with Firefox versions 57+ and hasn't even been updated in 6 years .....

You might find this article interesting :

Hi Happy,

yes, this is the Add-On and I installed it when I had a much older version of Firefox, but no matter whether or not I update Firefox I can't find the location of this add-on, but in both cases (old and new FF) I can see it in my add-on list (though obviously it's deactivated in the new version).

I was thinking about maybe opening HideTab's code and updating it so it'd be compatible again, because Diego (the author) told me it wasn't too hard, but if the FF team plans on integrating that feature into the core software, then I shall patiently and happily wait for it to become available. Just please add keyboard shortcuts for quick and smooth hiding and unhiding. HideTab may be simple, but it's very nice to use, so maybe you can just copy the code and adjust it as needed?

Cheers

Alex

Hi again Alex,

If you can do that - what you and HideTab's developer talked about and update the code, I'd be in awe - my knowledge of coding is 'below zero' ...

I thought what's mentioned in that ghacks article sounds promissing,
though ..... (?)

But (if you want to) you could always submit a suggestion here  :

https://qsurvey.mozilla.com/s3/FirefoxInput/

Quoting you :

"Just please add keyboard shortcuts for quick and smooth hiding and unhiding. "

You could submit that suggestion  !

What I always do is copy the URL of the tab and paste it somewhere
where I can easly find it - but that will probably sound like too much of a
hassle, eh  ? I'm sorry I can't be anymore helpful - maybe somebody else will come to your rescue here ......

Well, I can only maybe do that if I find out where the code is. :-)

But I followed your advice and posted the suggestion, so hopefully it will be included.

You can right-click the Add to Firefox button on the page Happy112 posted above and use "Save Link As" to save the XPI (ZIP) file to your hard drive.

Note that the extension has minVersion:5 and maxVersion:7 in its install.rdf file (2011).

You said (and I quote) :

"Diego (the author) told me it wasn't too hard "

Maybe he could prove it and show you ..... the least he can do for a
loyal fan  !

Hahaha, how I wish that a trick like this worked. :-)

Firefox doesn't unpack extensions automatically, so for most extensions (all WebExtensions) you only see the XPI file. An XPI file is a ZIP archive, so you should be able to open such a file in an archive manager application if you want to inspect its content.

I just sent an email to Diego (the developer) and gave him a link to this thread ......

(Fingers crossed ..... )

If the extension is installed and shows in about:addons then you can check the extensions.json file in the profile folder for more detail of this extension.

You can find the install location of a specific extension in the extensions.json file in the profile folder. You can open the extensions.json file in the Scratchpad and search for this extension. The descriptor field should list its install location.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

@cor-el: Thank you for the explanations! Now I was able to find the code.

@Happy: Thanks for sending the E-Mail, I shall keep my fingers crossed as well.
