Should not block internal pages

[naoliv]

For example, if I have reached the maximum number of tabs it just won't let me open about:addons

about:* should all be part of a whitelist, and always be opened (no matter the amount of tabs that I already have)

Came here to say this.

Workaround: open about:addons in an already open tab to change max-tabs setting to more tabs than you currently have.

I see why this can be inconvenient but I sometimes found I have too many about: tabs open 😄

I'm not sure if the API allows me to query about:* tabs, the pattern matching only accepts <schema>://<host><path>. I'll need to add "tabs" permission and filter by url. I'm not sure if I want to add that.

I'd like to add another request for this: I installed the add-on having more than 10 tabs open meaning I couldn't get in to change the preferences (I found myself unable to click on the icon to set them).

@kanru, this needs to be fixed 🙂

All internal Firefox tabs should always open: in the same way that these same tabs/sites don't allow add-ons to work on them (you can't close an internal Firefox tab with a mouse gesture), Max Tabs shouldn't be able to prevent them from opening.

It's fundamental that about:preferences should always open, when requested. It's really scary for a normal user to not be able to reach the browser preferences.

This bug should have a high priority!
