Retiring IE11 support for the Atlassian Marketplace website

After the release of Microsoft Edge, Internet Explorer (IE) has not received any major updates or added support for many modern web standards. Microsoft recently discouraged the use of Internet Explorer as a default browser, and we’ve also seen a decrease in IE11 usage across our cloud, server, and Data Center products over time. Atlassian products have already announced the end of support for IE11 in an older community post. This now extends to the Atlassian Marketplace website.

To allow us to continue to take advantage of modern web standards to deliver improved functionality and the best possible user experience across all of our products, we have decided to end support for IE11.

What does end of support for IE11 mean

End of support means we will no longer fix bugs that are specific to IE11 and will begin to introduce features that aren’t compatible with this browser.

When is this happening

We will officially end support for IE11 on March 1st, 2021.

What does this mean for you

In preparation for the end of support dates, we recommend switching to one of our supported browsers, such as Microsoft Edge, Google Chrome, or Mozilla Firefox to use the Atlassian Marketplace.

Please comment below with any additional questions and a member of the Atlassian team will be sure to assist you. If you have any technical or compatibility concerns with this move, please contact support.



We are having an issue with this URL opening correctly from Word and Excel. When we attempt to do this the URL opens in Edge but prompted with a page that Marketplace no longer supports IE11 even though it has been opened in Edge. Please note this behaviour only occurs when clicking on the link via Word/Excel. Using the URL direct in Edge works successfully.

Please advise.

Hi @StevenHassell, I’m an engineer on the marketplace team. Would you be able to help us with a few more details?

  • What versions of Edge and MS Office are you using?
  • Could you confirm if you see the prompt to upgrade browsers, but the site itself is still useable?


We’ve resolved the issue, we are using an older version of Office (2016) and it was passing through the Office Protocol which is in IE 11 format, there was a fix from Microsoft which resolved this.



Hi All, @StevenHassell

Could you please inform which fix from Microsoft resolve the issue?

I am getting the IE11 not supported error trying to use Firefox v90

@AllenChesley that shouldn’t happen. Could you more details about your OS and help us with a screenshot?
Do you have any extensions that might be altering your user agent?

Hi, i am facing issues with my site. Please check it & solve the browser. It is working fine in other browsers e.g: Opera, Chrome etc.

Why I am getting “Marketplace no longer supports IE11” and cannot get to go to with my Chrome and Safari? If I checked website , it recognized my chrome just fine.

Hi @RagnarVeerme, I’m an engineer on the marketplace team. Could you let us know what versions of Chrome and Safari you are currently using? A screenshot/video of the issue would also be helpful.

This issue just got resolved by itself I guess after two days. But thanks for the reply.
