Closed as can't reproduce? This is unfortunate! Whenever I open epic with a substantial amount of child issues (like 20+), it is the page is so painfully slow in Firefox, that it even sometimes puts up this banner proposing me to stop JS execution on it or wait. This is a shame ticket got closed.

A commenter - Jans Harder - pointed out that blocking https://\{yourcompany}.atlassian.net/gateway/api/gasv3/api/v1/batch helps. Based on other comments in the same chain, I added the following URLs to uBlock Origin's rules and it helped:

* https://yourcompany.atlassian.net/gateway/api/gasv3/api/v1/batch * block
* https://yourcompany.atlassian.net/rest/internal/2/log/safe/warn * block
* https://yourcompany.atlassian.net/gateway/api/gasv3/api/v1/p * block

Which analytics URLs did you block, and how?

Thank you!

I can still reproduce this bug with Firefox v133. Steps to reproduce - just load a page/ticket in Jira and start typing in the description field. There's a tremendous lag before any characters show up. Additionally, Firefox's memory consumption goes on increasing only if a Jira cloud page is loaded.

Opening a page in Edge doesn't show this behaviour.

Blocking the various analytics URLs at least stops the lag while typing.

Hi 7fb29b58b3e4 ,

I'm an engineer from the Confluence Integrations team, and I wanted to share that I tested it across Firefox versions 131.0, 132 (latest), and 114.0.2 (the oldest version I could get). In all these versions, Project Pages loads consistently without any lag.

Additionally, I ran a quick browser performance profile and compared it with Google Chrome, and I’m seeing similar load times (~28s) for typical interactions on the Project pages, as shown in this attached video: Screen Recording 2024-10-30 at 1.58.47 PM.mov

To help us better assist you with this issue, could you please share the following info from your latest run?

1. A screen recording highlighting the user experience while loading Project pages.
2. HAR file capturing network calls when initially loading Project pages, and
3. Any errors visible in the Browser Console tab when loading Project pages

These details could help us identify if there are any specific delays and pinpoint the components that may be slowing it down.

Thanks for your patience, and please let me know if there’s anything else!

Best,
Shrutha
