Hi I support young people ( aged 7-11) with Dyslexia. they all use Firefox to log in to their lessons. It automatically recognises them and it is a system they are familiar with. All of the lap tops up grade to the latest system automatically. One of them does not work on the new version. The students get a message which says version 78.0.2 is not compatible with 78.0.1 It is a Windows system. This is really distressing for the students using this lap top. They blame themselves for the problems and itis having an affect on their confidence. Can I revert it back to the older version ? and if so how? I really would appreciate some help as my wee students are upset and i don't know how to help.

Are you sure that is what the message says? Sounds odd.

Are you having the same problem? Do they have non-standard programs on their systems?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

This usually means that something went wrong with updating and that there is a mixture of old and new files in the Firefox installation folder. This can be caused by security software that prevents Firefox from updating all the files.

You need to do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced.
You may have to disable security software temporarily in case the problem persists.
