IFRAME is injected on blacklisted sites

[richardb64]

I'm opening this issue because:

• I'll report a bug
• I'll propose a new feature

Description

When Vim-Vixen is configured to "blacklist" a site or partial URL, it seems still to inject its console IFRAME. The existence of this frame is sufficient to break some web sites.

Desired Behaviour

When Vim-Vixen is configured to be disabled on a particular site or page, it should not modify the DOM at all.

Steps to Reproduce

1. Identify a site which breaks when Vim-Vixen is enabled, due to an IFRAME-related issue (eg. Addon breaks Website 'SecurityError: Permission denied to access property "document" on cross-origin object' #250, ServiceNow web application does not display when Vim-Vixen is enabled  #373).
2. Add the site to the V-V blacklist.
3. Visit the site and observe that it is still broken.
4. Using the Firefox debugger, observe that the V-V IFRAME is still present in the DOM.

System configuration

• Firefox version: 69.0
• Vim-Vixen version: 0.24

Console logs

The precise error will depend on what the web site is trying to do, but typically it will be a variation on SecurityError: Permission denied to access property "document" on cross-origin object

Still present on v0.26 and FF73. I need to disable the plugin in order to be able to read the mails. :(

Hi. Until this issue is resolved, I've found a workaround/hack for this. I created a simple Greasemonkey user script, that just removes the iframe from the site.

Bumping this issue, as it's still present in the latest version of VimVixen. The userscript posted by @mwuttke97 does the trick, but it would be better not to have to use it!
