Nice to meet you all. I have poor English skills, so I use a translator to post. Thank you for your understanding. I would like to report on a problem I found today. First of all, the symptom is "Unable to log in at Evernote.com". To be precise, if you try to log in using a normal ID/PW on Evernote.com, it will respond as if the PW is incorrect. However, since I checked the ID/PW several times, I determined that there was no problem, and as a result of trying the following combinations, I determined that it was a problem with Firefox for Desktop. (1) Desktop , Using Firefox -> Can't Login. (2) Desktop , Using Microsoft Edge -> OK (3) Desktop , Using Google Chrome -> OK (4) Android , Using Firefox for Mobile -> OK (4-1) Android , Using Firefox For Mobile (Desktop Mode) -> OK (5) Android , Using Google Chrome -> OK In the same experiment as above, each version is as follows. Desktop Firefox: 109.0.1 Mobile Firefox: 109.1.1 My guess is that Firefox's anti-tracking privacy part has a problem with the evernote.com site at some point. Turning off Privacy Tracking Prevention does not solve the problem. If there are other users reading this article and have an Evernote.com account, please try logging in. For now, I'm using a different browser, but I hope it works out normally. Have a nice day everyone.
