I have used gmail including calendar and contacts with Firsfox for 5 years, suddenly contacts and calendar will not open, has a Firefox upgrade caused this problem?

From reading other entries it seems that Firefox has made a blue, as we say in this country (Australia). Any chance of Firefox fixing it? Otherwise it's bye bye Firefox. I don't have the expertise or patience to go through more of fix routines.

Hi,

Sorry you experience that. Here are some standard troubleshooting steps that may resolve the issue:

1. Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield icon in the left part of the address bar.
   • If ETP is enabled, try disabling it.
2. If the problem is not fixed, try clearing Firefox cache.
3. If it does not help, try clearing cookies and data for the website you experience troubles with (warning: you will be logged out on this website).
4. If it also does not help, try running Firefox in Troubleshoot Mode. If the problem doesn't persist, please follow the steps from this article to troubleshoot further.
5. If nothing from the above helps, try creating a new Firefox profile and check if the issue persists there. If it doesn't, you can start copying files from your old profile to the new one to identify which one causes the issue. See this article on what files to copy.

Does any of the above help? Looking forward to your update on how it goes!

Hello Denys - hope you are a human and not an extension of AI but here goes: Thanks for the advice but it didn't work so sadly I will have to desert Firefox after a number of years. I have neither the expertise or patience or knowledge to continue to follow all the instructions that I have come across to fix the problem of suddenly being UNABLE to load my Contacts or my Calendar in Firefox. However I did try what you suggested/ They both upload within Google Chrome okay.

It seems to me that some upgrade that Firefox has made recently has caused the problem, all of the fixes I have tried have not worked. It also seems that Firefox doesn't appear to care about this issue which has obviously affected others judging by this Support area. But so far no corporate response!? I'll just consider my self a victim of progress and AI.

Phil, the whole corporation actually uses gmail and contacts & calendar internally, so if an update would break it, thousands of people would notice. There are no other reports like this, so it's an isolated issue that might be specific to you — that's what Denys is trying to untangle… as to what factor could be the culprit, for you, specifically.

I'll try to summarize the troubleshooting process here to give you the idea: it's to try to start with gmail in sort of a clean slate, without any crud they might have accumulated previously. So you basically sign out of gmail, click the shield in address bar and "clear site data & cookies", disable any addons (esp. any "privacy" or "security" ones — you never know how third–party extensions interfere with any big sites' code…), open a new Private Window, and sign into gmail from there to see if the calendar/contacts apps work there.

it didn't work

Hey Phillip, do I understand correctly that the issue reproduces for you in a clean Firefox profile?

That's correct, I opened anew profile and have now lost the old one. Incidentally the answer above saying no one else has the problem is incorrect, there are some response I saw where people were saying they had the same problem. See Sidebar. I'll try a few things tomorrow, I've wasted half the day on it so far. Thanks

If you have links to other reports please do share them here — maybe there would be a pattern to help. I'm looking at current public webcompat reports and do not see anything similarly sounding right away.

This question has "0 have this problem", and two searches linked from sidebar, from one person 5 years ago, and second person 15 years ago. Both caused by addons.

(The only thing that remains after all the browser troubleshooting steps is if something blocks it on system level — e.g. if you use a VPN or an antivirus or malware protection software that you can try disabling for a bit to see any difference.)
