Opera 8 beta 3 introduced support for User JavaScript. On this page I'll link to compatible scripts that can be pasted in my example framework file user.js. Paste the new function at the end of the framework file, and call the function from one of the three handlers in the top of the file. I've also provided Greasemonkey installable versions (using anonymous functions) where possible for those who want to try them in that other browser. These scripts have all been tested at least a little bit.
See also the links to standalone User JavaScripts for Opera below, some interesting scripts I saw in the Forums or newsgroups or elsewhere.
A big and nicely organized collection of User JavaScripts is building up at UserJs.org. I'll move some of my scripts to that repository (some of these scripts or the ideas for them have already ended up there), and only keep some examples here and links to interesting scripts on other sites.
//Remember password
// Makes the browser ignore web site requests to not remember passwords.
/*
Script source:
Jesse's Bookmarklets collection
http://www.squarefree.com/bookmarklets/forms.html#remember_password
Changes:
Made the alert conditional, only shows when there is something to report,
and when variable 'showalert' is 1.
Removed the 'onsubmit' removal.
Simplified alert message.

Found in the Forums, Ukrainian Opera user vvsite offers two scripts to enhance Opera's functionality: a Flash Panel for Opera 8 and an autoFormFiller, both hosted externally, zipped. These scripts add little in-page toolbars to pages containing Flash or forms respectively, to quickly disable Flash but also to open Flash movies separately for easy download, or to save and automatically reuse form values on return visits to a page.
