Hi, I've upgraded to Firefox 99 (on Linux) and a website that works fine in Firefox 88 and Chromium 101 has stopped working for me - I can't get the log in form to show up. This is in a standard window (as opposed to private) with all add ons disabled, Enhanced Tracking Protection switched off for the site and protection settings set to 'Custom' with everything switched off (and same with protection settings set to 'Standard'). The website is: https://www.riverford.co.uk/ and then click on person icon in the top right corner. I'm having similar problems with other websites, eg https://www.ebi.ac.uk/interpro/ in a private window (but weirdly works fine in a standard window) - click on 'Example protein sequence' to fill in a sample sequence and then press 'Search'. In a standard window this works but in a private window the 'Search' button doesn't work. (If the search button does work for you, please delete the job afterwards by clicking on the rubbish bin/trashcan icon so as not waste their resources.)
