Can you post a screenshot? http://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem

Thank you for speedy response. Hope this annoying problem is solvable. How do I post the screenshot which I have saved on the desktop?

The same popup problem exists with Firefox, too, though it does not bother as much.

To post the image: In this question in the forum, type some text in a Reply box - eg: this is the image Below the Reply box is 'Add images' : click on the 'Browse' button and a window opens so that you can select the screenshot file you saved on desktop. Click on Open. The image should get attached. Then click on 'Post Reply' button.

This is the screenshot. Sorry, cannot find the "add image" button.

See image below on 'how to add image'.

This is the form page I am on. It does not look like yours at all. https://support.mozilla.org/fi/questions/1040012#reply-form-main. How to get the right form for me to post the screenshot?

I've had a look and it is only a different language. It says Lisää kuvia: with 'Browse' button below. I'm here: https://support.mozilla.org/en-US/questions/1040012

or if I click on the 'Post a Reply' button that was in the email. it opens here: https://support.mozilla.org/en-US/questions/1040012?utm_campaign=questions-reply&utm_medium=email&utm_source=notification

Here is the screenshot (or would be if I only could find the box for attachments such as screenshot). I am now on this page you are using https://support.mozilla.org/en-US/que.../1040012#reply-form-main and it looks exactly same like the ones I have used before for questions and replies.

Clearly we are not seeing what you are seeing. I see no difference in anything except for language version. Please send me an email with image as attachment. I do not generally respond to anything sent personally, as I keep all communication in this forum. But to get over this hurdle send to: mail at anje dot co dot uk

PS you could send me both images - the one regarding the drop down popup windows open in mini size and also the image of what you see when replying in the forum.

Hi christ1 Image showing pop up issue.

That pop up box is at least half the size it should be.

Please test to check this is not being caused by an addon. 'Help' > 'Restart with addons disabled.'

When restarted in Safe mode, check the menu icon pop up box size. report back on results.

Toad-Hall suggested to disable addons. Now this is where my popup problem makes life difficult: to access settings or any other functions (tools etc) is practically impossible as the popup window is unreadable or elusive. Addons could well be behind the problem and I would surely wish to test that.

I see in the image you have Ohje in the tab.

Is this 'Help' in finnish ? Does it have the option 'Restart with addons disabled' ?

Otherwise: Close Thunderbird. Hold down 'Shift' key and restart Thunderbird. It should restart in safe mode - there might be a small window asking for you to continue in Safe mode.

What version of Thunderbird are you using ? The up to date version is 31.3.0

What version of Firefox are you using? The up to date version is using 34.0.5

What is your OS ? eg: Windows Vista, Windows 7 etc.

Toad-Hall. Both Thunderbird (31.3.0) and Firefox (ver no ?) are uptodate as far as I know. OS is Windows 7 SP1 (latest update 19 Dec 2014). Thunderbird popups appear normal when in Safe mode. Now, what next?

Do you have any themes installed?

Zenos. No themes in use. (Note: popup problem over when in safe mode.)

Firefox is ver. 34.0.5 (updated Dec 9).

This means maybe one of your addons is causing the issue.

restart in normal mode then disable one addon at a time and retest the drop down until the issue disappears. This will then tell you which addon is causing the problem. Maybe an addon needs updating.
