Duplicate of #4

I have the same problem on Arch Linux, Firefox 31, but on Mac OS X it works well.

Oh, is this UI issue the same issue as #44? That issue doesn't have any screenshots, and I can't tell from the description. If this is the same, this could be an excellent clue for how to reproduce this, which I have been unable to do so far.

This does seem to be the same issue as #4 - I just ran into this myself, and my stack trace is identical to @denadai2's (I ran a diff, and literally the only differences were our usernames and randomly-generated bits in the profile directories). It's also very similar to @diracdeltas' stack trace in #4 - again, diffed them, and the only additional difference is that it references line 307 in popup.js instead of 335 - presumably due to some unrelated code changes above it between then and now.

There is some strange flashing of content, it looks like it attempts to resize the popup to the correct format, and then fails and falls back to just embedding the full page. I'm not sure if it is helpful at all, but just in case I made a quick (low-quality so it could handle the framerate) video/GIF of what it looks like:

It's unfortunately difficult to see, but it initially shows what was previously there, flashes a smaller window with a tiled background that seems to fit, then expands back out to the full page. I took a few screenshots (scaled down to fit here better) to demonstrate:

@evanj you can reproduce the error with this live cd: http://www.linuxmint.com/edition.php?id=158

Firefox 31.0 under windows 7 suffers the same issue too.

Update: same problem with Firefox 33 and Ubuntu 14.04. I can't use Mitro because it doesn't work.

Hard to recommend Mitro when it doesn't work with firefox.

Tested with v33.0 on Ubuntu 14.01 and experiencing this issue.

I have also tested with Windows 7, not sure what version of Firefox but probably the latest there as well.

I have this problem in Arch Linux, Firefox 33.1.1
I wanted to point out that I use hidpi scaling
Under about:config, I set this:
layout.css.devPixelsPerPx
to 1.3, which scales to ~130%

👍 Seems to be a fairly serious issue (though I imagine it works on non-linux systems)?

Chrome plugin works fine.

windows 7 has the same error in some enviroments

Can confirm this issue in FF 36.0.1 on Windows 8

The problem still occures on firefox 37.0.1 on Manjaro.

The problem still occurs on Firefox 38.0.5 on Windows 7 SP1.
