every time I open this forum in latest FF it freeze for about 20s and then says Script is not responding. If I click on Cancel, it shows me blank page. If I click on Wait, it displays forum immediately and it works ok until I close the forum and open it again.
This is the link to the JS script https://discourse.osmc.tv/assets/vendor-7018bd051b2491ae35248e8aa1125f12.js
It works ok in Chrome
Try to disable all your FF plugins to see if any of those are the cause. If you have any.
What version of windows are you running?
36.0.1 And plugins does not seem have any affect on it.
I meant windows version. not FF. But it shouldn’t really matter.
I can’t replicate the issue on windows 7 with a fresh FF install. Try to clear all cache and set all the FF settings to default.
If that doesn’t help try to uninstall and reinstall FF.
