Have you tried Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#search

Try toggling security.csp.enable to false on the about:config page. Let me try the links in Linux and Windows. Can we also get a screenshot of the performance tab in Taskmanager. I just want to see what you're working with. Also the make and model of your computer.

Mine is currently false and all is well on openSUSE. I can move to different dates on all the charts. Let set it to true and see what happens.

No issues for me with it set to true or false. I can change dates with no problems. see screenshot

This laptop dual boots openSUSE and Win 11. Let me go try Windows. If you're running a Pro version of Windows, try this as a test and I think it's nice to have. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

What security software are you running?

All is well in Win11 for me.

I have not tried Safe Mode. Checking the problem this morning I see that if I stay on the same quote and in the chart I can change the time/date. I was able to move the cursor in Boeing with not problem. I then went to the tab to the left which is Tesla and it was hung and did not even show the chart and will not reload. When went back to the Boeing chart there was no cursor to move and again it was completely hung and I could not reload it.

Security.csp.enable is false as you can see. My system is a DIY Windows 11 Pro I should have mentioned that I have two other Firefox windows open with several tabs each. I doubt this is a problem but should have mentioned it. I am running Norton 360 Premium

Thanks for getting back to me.

I left the Firefox window open with the quotes tabs and walked away for over an hour. Now the tabs that were hung will reload and I have no problem moving the chart cursor in any and all tabs. I have attached the Task manager screen shots for Firefox Process and Performance. Notice i cannot get all the processes on one screen shot.

Thinking about it this may be a problem unique to my system although it implies Firefox can get into a weird situation.

i do hibernate my system every night so that is a variable.

Again thanks for your help.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

zeronight and jonzn4SUSE:

thanks for the suggestions. Being of slow wit I finally tried the same Firefox setup on my Dell Windows 11 Intel 11 system and do not see the problem. This system started as a Windows 7 PRo that has been upgraded successively to 11 Pro and Firefox uses the same profile. It is clear that it is a problem with my system. It is certainly not worth any more support time. I do thank you both for taking your time to try and help me. I am going to mark it as solved since it only seems to occur on my long lived desktop system. Pauljg
