Strange/odd behvious on Firefox Browser

Bug Reports
1

Today I’ve noticed that the calendar when logged in on a Firefox browser is not showing today’s date and any of the three activities that would have been synced.

the latest day it shows is Sunday 30th March

If I open the same account on Edge it shows correctly with today’s activities all showing

same machine, same account, same time.

Here is a shot of them side by side, Edge left, Friefox right

tried clearing Cache/Cookies on Firefox but it hasn’t had any impact, also restarted the machine (Win 10) in case that helped, but it didn’t …was all fine when I recorded Saturday’s activity.

Intervals.icu includes the week in the URL to facilitate deep linking. So maybe you have that in a bookmark? In retrospect doing that was probably not a good idea.

https://intervals.icu/?w=2025-04-07

intersting…but checked and not included in my bookmakr

also the same issue if I type in the URL direct and nothing is autocompleted

Interestingly, the URL in the working browser (edge) shows as

//intervals.icu/?w=2025-04-07

but if I copy that directly into Firefox address bar it instantly changes to

//intervals.icu/?w=2025-03-24

and no matter how often I try to retype it never shows the first week in April (including the last day of March)

also if I put the activities into list view, again you can see Edge (left) shows all activities including the three from Monday 31st March, but Firefox shows nothing after Saturday 29th March

For clarity, just checked and it also works as expected on Safari and Firefox browser on my phone 9 (Iphone 14 pro)…Also tried Brave browser on Windows and all good there as well…so just impacting Firefox on Windows

to add to the oddness, not only have todays handful of activities not jupdated…on fireforxc again (fine on Edge)

Im now seeing this popup on Firefox

so something in Intervals appears to be impacting Firefox…

Nothing has bee updated so I’m even more confused now and Firefox is now basically unusable for Intervals website

You could give Firefox ESR a try , it works for me , activities on march 31 and today are visible. I am running ESR 115.13.0 , automatic updates blocked…

Didn’t know about this. I’ll give it a try and report back. Thanks

Chiming in as using it on Firefox too (no issue on my end) :

Thanks. This is even more odd then. Not home now but will check when back in a a few hours.

Wondering if something has messed up via daylight savings change…just not sure how it would only affect Firefox

9

tried ESR, no joy.

Tried completely removing Firefox and reinstalling fresh…no joy

still not showing anything after Sunday 30th March, looks like Ill have to use Edge instead

10

Try Brave if you want FireFox functionality.
Way more privacy then Edge.

11

Might be some extension you installed?

12

oddly nothing new has been installed extension wise in months BUT…

I looked thorugh the list and started removing a few I didnt think I needed and when I removed rthe daylight saving one…this started working again…so that obvioulsy had a bug in it somewhere

but all good now so thanks for the nudge…next time I get browser issues Ill check extensions first but for now this is all good
