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

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

Chrome:

Firefox (latest):

Firefox (114.0.2):

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

This is still a issue as of 10/28.  Can you guys please address this.  Thank you!!

Firefox version:  131.0 (aarch64)

I have started to notice improvements in regard to CPU and memory usage, not sure if this is due to a Firefox upgrade (I'm on 131 now) or due to some changes in Jira.

85453917d6ec - What firefox versions have you tested this on? I would recommend testing at least with a couple different versions to make sure people with slightly older browsers are also not affected. You can find older firefox releases in their archive: https://ftp.mozilla.org/pub/firefox/releases/

I would also like to hear from other people what their firefox versions are when they hit this issue. Sadly, I did not record what firefox version I was on when the issue was present and/or when the upgrade happened on my machine.

According to some online sources for browser stats, it might be worthwhile checking all the way back to Firefox 115: https://www.stetic.com/market-share/browser/

Yeah, how much effort was put into this "reproduction"? 

You tell us to contact support, so you can wipe all individual internal cases under carpet and no one knows. THis is what happened to me many times - always cannot reproduce, so you close it and happy days - happy stats. Worst support I've ever experienced - ever. Cannot imagine we pay for this. 

Hi everyone,

This is Howard from the Confluence Integration Team. Thank you for raising this bug and bringing it to our attention. This ticket specifically addresses Jira Project Pages, which is the Confluence <-> Jira Integration. After examining this issue, we were unable to reproduce the behavior within our instances. To set the right expectations, we are closing this bug because we cannot fix the issue if we cannot replicate it.

If you are experiencing performance issues with using Jira in Firefox, please contact support to create a new bug report. If this issue persists for you, please let us know by contacting support and referencing this bug.

Thank you again for providing valuable feedback to our team!

Best,
Howard
