Add Safari support (done)

[fregante]

Safari has its own permission system which would replace this module

However this module should be updated to avoid adding a non-working context menu item

[fregante]

I found out why: tab.url is an empty string for some reason. activeTab should fill that in.

https://github.com/fregante/webext-domain-permission-toggle/blob/2aacb195e7fbaaf04e23c32b074b5bbd10651732/index.ts#L88-L92

If this can be fixed, I think this module is still the easiest way to build cross-browser extensions since we don't have to customize the Safari build.

tab.url is empty because apparently context menu clicks don't "activate" the tab (activeTab permission). Left-clicking the browserAction first and then clicking the context menu item works, but that's awkward.

This bug might be solved by Safari in the near future or it might not.

I have 2 "solutions" for this:

• Detect Safari and just hide the context menu item. The developer would have to document this manually.
• If tab.url is missing from the event handler, instruct the user to click the icon first. This frees the developer from having to document this behavior.

Perhaps I use both:

• By default, keep the menu item and inform the user
• Offer an option to detect and exclude Safari, like addDomainPermissionToggle({safari: false})

I think I found a workable solution!!

Step 1: Ask the user to try again.

if (!tab.url) {
    chrome.tabs.executeScript({
        code: `alert("Try again pretty please?")` // Alert doesn't work from background in Safari
    });
    return;
}

Step 2: Bind the request/remove functions to chrome.permissions because that's how Safari likes them.

Step 3: Make sure that the menuitem checkmark is updated correctly when it fails

However webext-dynamic-content-scripts also needs to be fixed.
