Add "2/4 split view"

[ohlalayeah]

People have been requesting "split view" feature of firefox browser, to split into 2 views (horizontally). Currently Google Chrome supports this feature. However, it is not enough, please make firefox support up to 4 split views which can be spited horizontally and vertically. For 2-3 splits, users can choose horizontal and vertical split; for 4 splits, users can choose horizontal, vertical or quadrant.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

I would love to see this feature, was just thinking it could be great to have a 4 way split view and a 3 way split view. Also being able to split horizontally instead of vertically. I hope it will be implemented.

As always, thank you devs and mozzilla team.
