See enclosed images; when you resize the firefox window, you get some clipping of the webinterface but never the complete picture. Any suggestions? Thanks.

Have you tried the above?

How about using full screen (as a test) ?

Can you post a link to a public page?

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Open the Add-ons Manager <Control><Shift> A and disable All of them.

Hi, Yes I tried all of the above. A full screen apparently doesn't show anything, but I can see a 2 pixel line in top of the screen (see enclosed screenshot with ispector screen enabled). I ve disabled all add-ons and virusscan, same result.

Best regards

In the image you posted, I noticed that the corner is darkened. Have you tried moving it with the mouse?

I have called for help on your problem.

Yes, without any luck (the mouse pointer doesn't change).

Hi sander.terhorst, and thank you FredMcD for the tag! This is in response to the Helpdesk tag where we can get some Mozilla eyes on this. So far I understand that after the recent update, the Juniper J-web management page is not showing correctly when Firefox is in full screen as well as when all of the add ons are disabled, nothing shows. But if you try to resize the web page, some of the html will show like here

Some troubleshooting thoughts: Have you reported to the developer of this interface as well? Does this happen in other browsers?

Are the css rules for the site using the align webkit? Please note to the developer that the rule was removed: https://developer.mozilla.org/en-US/F.../31

Does the html page start with: []?

Does the css on that page use: vertical-align: top; ?

Does this site use flash? Please make sure that this is up to date to version 15.

Most of these questions are along the lines of site compatibility. It seems as if we have done all the troubleshooting we can for the current Firefox, however if it does not appear this way in other browsers, it is most likely a web compatibility issue. webcompat.com is a great place to help get issues like this solved.

However in the meantime, please update your plugins, and try a new profile to make sure its not a corrupt profile, this will help investigate this further.

Thank you!

I think all answers are 'no' (html/css/flash). Youre are right about reporting to the developer of the software: Juniper. They built great switches so they must be able to create a webinterfaces up to the standards :-) I created a case at Juniper.

I installed Opera which works fine (lot's of other issues with IE). Thanks for your post and I will keep you advised.

Response from Juniper Support:

"According to the case notes, I understand that the J-web is not working on the latest Firefox version.31. This is a know issue with the latest firefox code and we have an internal PR for this issue.

PR number: 1019929

PR description: issue after migration to Firefox V.31 and V.32Beta According to the PR notes, currently supported versions are only IE7 and FF 3.x. However the latest browsers are getting supported up to FF30, IE9&10 in the upcoming EX Junos releases."

Apparently we have to wait for the new Juniper firmware.

HI sander.terhorst, Thank you very much for reporting back to the thread! Keeping it open and helping other users :-)
