Since upgrading to FF 19 on sites that I visit regularly certain text boxes (user input) try and show data that I have entered previously but it is compressed into a single line and is unreadable

This also happens for select boxes where the options are compressed into 1 unreadable line

Chosen solution

Try to disable hardware acceleration in Firefox.

In Firefox Safe mode these changes are effective:

  • all extensions are disabled
  • the default theme is used (no persona)
  • userChrome.css and userContent.css are ignored
  • the default toolbar layout is used (localstore-safe.rdf)
  • the Javascript JIT compiler is disabled
  • hardware acceleration is disabled
  • plugins are not affected
  • preferences are not affected

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

OK - Starting in safe mode does appear to remove the problem

However if I manually disable (and then restart FF) all my add ons then the problem persists.

This would indicate that it's not an add-on problem but something else.

Safe mode appears to leave all plugins enabled - could it be one of these?
