Was having troubles accessing tinkercad.com. Updated to Firefox 114.0.2 on win 7 64 pro. Can now access website but when I export a file from there, and try to open it from downloads, windows explorer gives error "not responding" when I choose restart the program, the file opens. This did not happen until upgraded firefox. And it did not happen in EDGE. I have system restored, and went back to the site not responding. updated fire fox again, and it keeps happening. My win 7 works fine, and no, I do not want to update windows on this computer. thank you for your help.
