Live Doc pages hang in Firefox since ~Apr 18

Hübner_ Andreas

Since approximately April 18, Live Doc pages on our Confluence Cloud instance hang in Firefox (Firefox 149.0.2, macOS). The spinner runs indefinitely and Firefox eventually warns "this page is slowing down your browser." Legacy pages load fine.
Safari loads the same Live Doc pages without issue.

Ruled out on the client side:
- Extensions — disabled individually and together
- Firefox Private Window
- Cleared service workers and all site data for atlassian.net
- Fresh Firefox profile
- Disabled Enhanced Tracking Protection
- Atlassian status page showed no incidents Apr 16–21

Questions:
1. Did a backend deployment to Confluence Cloud around Apr 17–18?
2. Has anyone else seen this on their Cloud instance since that date?
3. Is there a known fix or ETA?

Workaround right now: use Safari for Live Doc pages.

UPDATE 2026-05-07

The issue went away as sneaky as it appeared. Roughly a week after I reported this, all was good again. Indeed might have been an unreported / undocumented problem with the Confluence Cloud web app per se.

Hello @Hübner_ Andreas

Are you on Free or Higher Tier Subscription?

Hübner_ Andreas

I believe Cloud Confluence Standard. Not sure the exact tier.

You should Open a Ticket for further investigation.

Hi @Hübner_ Andreas and welcome to the Community.

Here's what I would try:

Firefox is now on version 150 (at the time of writing) so if you can, try updating the browser on one computer and see if it might rectify the issue.
I would also try converting one Live Doc to a page, then converting it back to see if the issue persist.

If things work in Safari just fine, I'd say it's a browser issue.

As a Confluence veteran, I went through several stages of browser grief and compatibility issues. For example, with Server, my team had to switch to Firefox because Chrome was causing issues.

With Cloud, we had to switch to Chrome for the exact same reason. My team member prefered Firefox but had to do specific operations in Chrome.

For a couple of months, Chrome kept disabling a modal from a marketplace app... so I had to use Firefox. The issue fixed eventuallly fixed itself.

Same issue here,
Confluence slows down FF 149.0.2 and 150. Site unusable. FF stops the page from loading.

No issues with MS Edge but prefer Firefox.

Issue is not persistent. After logging in on this forum I could stop the confluence page, refresh and FF worked. Could it be some kind of authorization issue?

@Kris Klima _K15t_ been there. From time to time switched Browsers because something not worked.

Hübner_ Andreas

Same, update to FF 150 did not change anything. Also noticing performance issues not only on Live docs (just had the same thing on a Space Home page, that is still a legacy page), but essentially any Cfl page (but especially on Live docs)

Hübner_ Andreas

Thanks for the recommendations! Not keen on switching browsers per web app But yes, that's what I'm doing currently.

I've raised this also with our IT dept, let's see what they come around with.

Even after checking the recent Firefox changelog, my IT intuition tells me the problem is likely on Atlassian's side, not with the browser.

Our company is also affected by this But we have issues with regular confluence pages as well. At least since last week, but maybe this started about two weeks ago. It's not always reproducible, it only happens sometimes. But often enough that most of us have switched browsers... Sometimes the Confluence tabs even crash completely.

Clearing the cache, switching to private mode, disabling ad blockers etc did not help

Hübner_ Andreas

I have the impression it got a little better yesterday and today. Live Docs still load fairly slowly, but I did not encounter the full freeze anymore. Will keep the post updated.

Did not update Firefox, so must have been something on Confluence/Atlassian backend side.
