This error comes up on so many sites now. I am thinking of deleting this terrible browser and moving to chrome despite all of my uni resources being on firefox. Does anyone reccomend browsers?

I have tried everything and nothing works, I can only use websites in troubleshoot mode but don't unsderstand what the problem is in the code (I am not a dev or software engineer so I have trouble getting rid of the problem in code because I barely understand the code).

I don't want to have to only use this browser on troubleshoot mode, I have tried disabling add-ons that could be the issue like Adblocker but to no avail.

This is now effecting my studying and dissertation writing.

No such problems here, I see a short flash about "please standby while we are checking your browser" and get redirected to the login page:

Did you check the Web Console for possible messages like about accessing canvas ?

You haven't made changes to Firefox settings that could effect this as it is likely that the server has a problem with your browser?


You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose, make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website, data for that website will be saved once again.

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works, you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
