- All options are disabled by default, so if you don't edit the files, nothing will happen.
- Items that appear in different contexts with the same ID will disappear in all those contexts when activated only once. This is because many menus internally share the same very big context menu and are separated here for more convenience.
For specific problems please open an issue, there may be workarounds.
Hide Pocket / Sync / Screenshots
If you don't use either of those "internal addons" at all, you can just disable them, which will also remove their context menu entries everywhere.
How to do it: Set the respective value in

Using simpleMenuWizard together with other custom modifications
Easiest thing to do is renaming the
userChrome.css that came with the zip package of simpleMenuWizard.
Rename it to
simpleMenuWizard.css and put it into
chrome directory next to the already existing
Open the old
userChrome.css which is filled with foreign code and add
@import url("./simpleMenuWizard.css"); to the very top. That's it!
You can now edit
simpleMenuWizard.css for a general overview and some options or continue with step 5.
Delete all the files and folders that came with this project.
So if you don't use other modifications, you can simply delete the whole [...]\profile.folder\chrome\ directory.
Restart your browser.
