Bitbucket and Jira not working on Firefox/Linux

Hello! I'm not sure if this question has been asked before, but since about 5 days, Bitbucket and Jira webpages don't load on my browser. I'm using Mozilla Firefox under Linux Mint Tessa. Every time I try to load one of these pages, they stay blank, but if I load them on Firefox/Windows10, they load normally.

Since my working environment is on a Linux Virtual Machine, I want to know if there's something to help me solve this issue, because I need to keep track of the repo I'm working on besides the Git CLI and it's not efficient for me to switch between OS to just check these pages (Only 8GB of RAM, my ram suffers every time I open Firefox on either system). I've tried refreshing cache, logging out and in and nothing happens.


Thanks in advance for your help!!

-- oops, not an answer but need to open a bug

I also get this problem in Firefox but on Windows 10. Bitbucket just spins forever. I get

Uncaught TypeError: parcelRequire.registerBundle is not a function

errors in the console. Yet it loads straight away in Edge and Chrome.


It's not working for me on Firefox on Mac


Same for me. I found a temporary workaround, described here <>. In a nutshell, from a Tools/Web Developer/Web Console:


Then reload the page. Works for a short while before the problem occurs again. Jira is basically broken on Firefox.

same problem login fierfox under linux

in console see

request block (no header CORS «Access-Control-Allow-Origin»)

Hi Raquel, welcome!

If my understanding is correct you're using Linux in the same machine you're using Windows, via a VM, is this right? I'm assuming that before that, Bitbucket and Jira were loading with no issues. To help you troubleshoot this issue, can you let us know the following?:

  1. Do you get any error or do the pages keep loading forever?
  2. Do other websites load?
  3. Which version of Mozilla Firefox are you using?
  4. Have you tried different browsers in the Linux part, like Google Chrome for example?
  5. Have you checked the developer tools in Mozilla Firefox? Do they show any additional information?

Looking forward to your response, Raquel. 

Best regards,


Hi Ana! Thanks for replying! Yes, you're right about the setup, and both pages were loading for at least two weeks in both systems when I created my accounts. Now, to answer your troubleshooting questions:

1.- No, the pages stop loading, but I get only a blank screen

2.- Other websites load, I can even get the Atlassian home screen to load, but when I try to see my projects on Jira or Bitbucket, blank screen appears

3.- I'm using the latest version for Linux Mint, which is 64.0

4.- Yes, I'm currently using Google Chrome since I made this post, and the pages work in that browser. It's just that Chrome is very resource-demanding for my VM and I try to avoid using it in there.

5.- I've checked the Firefox Dev tools, and the console gives me 2 messages from Bitbucket:

  • TypeError: " is undefined"
  • Unhandled promise rejection

And from Jira, it shows some JS libraries deprecated, errors about file corruption and the same Unhandled promise rejection.

I'll try to update my Firefox browser to see if something changes :)
