some suggestions on how to do it now here http://forums.mozillazine.org/viewtopic.php?f=28&t=2710625

I would recommend the userchrome route.

Thanks for the kind help, really appreciated. A few points here. 1) I used the <field name="_MAXRECENT">15</field> fix for years by editing the omni.ja file. But that does not work in version 68 as there is no folderWidgets.xml file. 2) I am not sure if the userChrome.xml will work as I also see 'Rod Whiteley's chrome.xpi extension is obsolete. Fix: viewtopic.php?p=12655643#p12655643' 3) I have no idea how to use these fixes with all the coding. Can anybody help. Best regards, Tony.

userChrome.xml/.css bindings do not work these days as far as I can tell. T-Bird just ignores it and the maxrecent folders value does not increase from 15.

I wish I knew where they moved that variable in TB 68.x to so I can continue to edit it, OR better yet, it needs to be added into the advanced config menu. this would be the best possible scenario so then only advanced users would be messing with it.

Any help with this from anyone would be appreciated.

thanks all

I found it. It's still inside the omni.ja file. Exit TB and go to:

\chrome\messenger\content\messenger\folder-menupopup.js

..and edit this file. You should see this:

// The maximum number of entries in the "Recent" menu.

       this._MAXRECENT = 15;

..you can change that value and then put the file back into the omni.ja file like you used to do with the folderWidgets.xml file and then re-run TB with the -purgecaches option and you should be good.

(TB folks, can you PLEASE expose this value within the advance config editor so we can change it easier in the future? - Thanks!)
