My O.S. is Windows XP (sp3).
I went on Firefox help and did what was advised resetting it by changing "layout.css.devPixelsPerPx" to 1.0 instead of -1.0 as indicated here: https://support.mozi... fonts&r=0&as=s
My pages went back to the same fonts I had before but I ran into a new problem.
However my menu bars, bookmarks and all, are now almost microscopic. I need to use a magnifier to read them. I searched again on Firefox Help but there are no answers to this new problem.
I have another laptop with Windows 7 I am not going to upgrade Firefox to version 22.0 that is a certainty. I don't want to have to deal with the same problem again.
I wonder how I could reset my menu bars do a readable format the same as before. I use I.E. only rarely so I don't really care but I would like my Firefox browser back to normal.
I hope somebody will have an answer on how to reset my microscopic menu bars the way it was before.
Some of you may have encountered the same problem. These updates can be a real bugger!
Thank you for reading my post.
