EDIT: Translated to the wrong language. Did Italian instead of French.

Hi Moses

I will repost here in english. I was a bit upset after following a french link and arriving without further notice in an english-only site. A Warning on the french site stating it's continued in english would be a plus.

My problem

Since upgrade to rel 27 my FF lost memry for many settings

File transfer option

Default start pages changed to FF default Page, Download update page, Firebug Update page.

All my personnas disappeared and Groovy Blue became my default theme. 5I never installed Groovy Blue)

What is still correct (inherited from previous verions) : my favorites and my passwords

Is it possible to reinstall REL 26 ?

Thanks for your help

And apologizes for my bad frenglish. ;-)

Sorry about that! The French forum you went to was probably a 3rd party and is in no way affiliated with this forum. Also, I did make a mistake by wrongfully translating into Italian instead of French, so see my correct above ;)

I'm going to try to understand your response so here goes:

Default start pages changed to FF default Page, Download update page, Firebug Update page.

I'm assuming these 3 pages start up every time with Firefox, correct? If so, you can revert this back to normal about:home page by going to Firefox button > Tools/Options > General > Restore to Default > OK' that will restore your home page to about:home

File transfer option

What's happening with this? Can you elaborate?

All my personnas disappeared and Groovy Blue became my default theme. 5I never installed Groovy Blue)

To my knowledge, I can't think of anything that would make your personas disappear after an upgrade to 27. Do you have an Old Firefox Data folder on your desktop? If so, you can restore them (i'm not sure you can though but give it a try) but be cautious.

Is it possible to reinstall REL 26 ?

We don't suggest downgrading to 26 since 26 might have bugs that were patched in 27, that's why we always recommend users to upgrade to the latest version (27.0.1 at the moment)

About file transfer I meant file download, sorry. My setting is "always ask wher to store downloaded files" After a restart it's allways set to default download location (ie in may user's download dir)

For the start pages, I can redefine my start pages a lot of tabs, but if I restart Firefox they will have disappeared.

I'll try your advices and give you some feedback.

Thanks for giving me feedback!

Your prefs.js file is probably corrupt from the Firefox update. This can happen sometimes. The below method will reset all users preferences back to default. (homepage, download location, etc) and might remove all add-ons, extensions, etc

Can you take a look at your profile folder (Click the Firefox Button > Help Troubleshooting Information > Show Folder) and see if there are any multiples of the following files:

• prefs-n.js
• prefs.js.moztmp
• Invalidprefs.js.

If so, can you delete them, then restart Firefox.

I have prefs-n.js with n from 1 to 233 !!!

Shall I erase all those 233 files ?

No prefs.js.moztmp nor Onvalidprefs.js

hi, yes delete all of them including the prefs.js file - this will reset all your settings again, but hopefully the last time - maybe the file was write-protected, which causes those anomalies...

Thanks a lot sir !

I could redefine the file download option to ask, some tabs to be open at start.

I could also reinstall some personas.

After restarting Firefox my new configuration was still there

You solved my problem.
