After the 55 update, the bookmarks are gone, firefox is unable to process the backup file, and the history does not show anything, not even the page it is open

Posted

After the 55 update, the bookmarks are gone, firefox is unable to process the backup file, and the history does not show anything, not even currently open tabs (or the page it is on). The computer lags (2-10 seconds) with any request to access the internet, though it will tell you the backup file cannot be processed instantly. I am running windows 10. It's so slow that I've had to use IE to write this; the troubleshooting information button keeps sending me to the 404 not found page when I press it. Any ideas? Oh, and the button below that makes an educated guess about the browser and operating system remains blank, though it may be because I'm not in firefox this instant. Thanks.

Firefox 55.0 - 55.0.1 updates were halted to address problems similar to the ones you are describing that affect systems where there is an apostrophe (single quotation mark) anywhere in the path to your Firefox settings. For example:

C:\Users\John'sHP\AppData\Roaming\Mozilla\Firefox\Profiles\abc123x9.Mary's Settings => one or more ' characters

A fixed version is in the works.

For now, you can reinstall Firefox 54.0.1 using the link in this article or one I send you by private message: Install an older version of Firefox.
