Why won't my Firefox maintain maximized window?

more options

For the longest time I had no trouble with my Firefox opening maximized no matter what which was good. But suddenly, all my profiles open up maximized like they should, except the one I really use and want to open up that way has suddenly stopped doing it.

I have maximized it and resized it and you close it and it opens back up to the same non-maximized size again and it is getting absolutely annoying and I don't have the time or energy to once again rebuild a profile that was created less than a month ago, this is getting ridiculous.

How in the heck do all the profiles that are launched (using the -p on everything) show up maximized like they should, but this one stupid profile which is my primarily used suddenly stopped doing it without any changes by me and it won't remember its position and size anymore?

For anyone who needs more information on this, if you have the option to resist fingerprinting enabled, it will affect your interface.

Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/Profiles
  • Linux: *~/.mozilla/firefox/Profiles
  • Windows: %AppData%\Mozilla\Firefox\Profiles
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
  • Windows XP: C:\Documents and Settings\<user>\Application Data
    \Mozilla\Firefox\Profiles\

Search for the above files. Then rename or delete them. Restart Firefox.

Thank you but that is not the problem. I appreciate you taking the time but this seems to be a security bug which has now been filed here:

https://bugzilla.mozilla.org/show_bug.cgi?id=1402557

Until we know the extent of the security implications, I am reluctant to reveal the fix that I discovered. If you have access, you can see it at the bug reported above, if not then I will happily update this and post the answer once the resolution has been reached with the dev team.

That was very good work. Well done. This is not the first time fingerprint was the cause of an issue.

It seems that due to the fact that they resize the window based on multiples of 800x600 based on your overall resolution, it will cause the interface to fail to remain the way you want it.

They claim that it is due to globalizing the number but the fact that they are using ratios, it still gives it away no differently than having it maximized and retaining that, so they need to revisit the way they have implemented this.

I am hopeful the new iterations will be less disruptive and behave better.
