I also noticed that I can reproduce the issue pretty consistently if this forum is the first page I load after killing Firefox and clearing the cache, whereas it usually works if I load some other page first and only then open the forum.
Interesting. I donāt have the feeling that I saw the same correlation so far. When it happened I repeatedly killed Firefox and opened that page first until it worked. But I had just as much trouble when I had been browsing other pages in other tabs before.

Probably this is not related, but can anybody open https://www.vmt-thueringen.de/ and try to pick a date and time for routing information? Doesnāt work for me on Firefox mobile, the calendar is strangely ordered, so I canāt confirm the date. Chrome seems to be working
Just to follow up: I have seen this happen plenty of times on Version 117 by now. So it does not seem to be fixed and is just luck.

you really should update your Firefox, 117.1.0 fixes a critical zero-day: Security Vulnerability fixed in Firefox 117.0.1, Firefox ESR 115.2.1, Firefox ESR 102.15.1, Thunderbird 102.15.1, and Thunderbird 115.2.2 ā Mozilla

Thanks for testing. Maybe it is caused by uBlock origin 
I already tried disabling all that. Itās also not FP4 specific. The FP5 has it too and I could also reproduce it on my Pixel 3 for quite some time.

I have missed this topic so far, but I have the same problem every now and then (it usually helps to force close FF and then try again). Will head over to bugzilla later.

I saw this thread sometime in the past, but didnāt care too much, because for on my computer was doing five. Now I changed from Lighting browser to Firefox when I moved from FP2 to FP5 and I have the issue both here and in a different forum based on the same software. Iām using uBlock origin, but otherwise the browser is more or less as it came. Will try to disable uBlock next time this happensā¦

That is interesting! I just came over here to say that on my FP4 it worked every time since I updated to A13. 
Iām using the forum in a Firefox PWA which did not load at least half of the time before. I had to kill it repeatedly until it worked.

disabling ublock and decentraleyes doesnt change anything for me.
Interestingly I didnt have problems for app. 1,5 weeks until 5 days ago it started to happen again from time to time.

Confirmed: Right after posting my previous message here I had the issue again, disabled uBlock and that didnāt change anything. Increasingly enough another website in a different tab didnāt want to load properly then anymore, either, although that page alone doesnāt have any issues normally.
In my experience the only thing that fully prevents the problem is to
- Enable the following setting: Delete browsing data on quit
- Check the following boxes: Open tabs, Browsing history, Cache
- Always use Quit, which will appear at the bottom of the app menu, after visiting a Discourse site.
These measures are not too detrimental I find, as long as you donāt rely on browsing history.

With me, the bug recently got much worse. The above procedure no longer works and I canāt load the Forum at all. I suppose I could if I wanted to empty all data, but thatās getting ridiculous. Clearing the app cache doies not help.
For the moment Iāve fallen back on another browser (DDG) just for Discourse.
Anyone else see this?
I switched completely to Vivaldi due to this.
Iāve always been using Vivaldi and have never faced the problem.
I donāt need to clear all data. All thatās sufficient is switch to a non-discourse page, āthrow away Firefoxā by swiping it out in the square button menu, and then relaunch it again. Sometimes I need to repeat this up to 10 times, but Iāll always get there without clearing data.

Yep, same here. After the A13 update I had no issues at all for some time. But since a few weeks itās back. Sometimes better, sometimes worse. But with enough tries it works eventually.

yes that helped, thanks! I could then load the forum and things seem back to ānormalā.
