OS X Mojave (full release) - FF freezes if trying to rename a file to save

Firefox 62.0.2 (64-bit) OS X Mojave - 10.14 - live public full release (i.e. not the Beta) MacBook Pro, with menu bar

Example: Using Google, go to Images tab. Right click on an image and select "Save image as". If you click on the file name, as you want to change the name, FF freezes.

Not only does it freeze but right clicking on the icon in the Dock only shows "Quit" (not Force quit) and that does nothing. Furthermore, it locks you out from being able to use the Apple symbol (top left) to get to "Force quit" that way. Only solution I have found so far is a forced reboot (i.e. power off/on).

I can reproduce this every time.

If anyone wants more info just let me know what you want to know. I suspect that, given Mojave has only been live a few hours, that a lot more people might run into this in the coming days.

Please try in : SAFE MODE

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Performance > Uncheck to view)
  • plugins are not affected
  • preferences are not affected

TEST''''is issue still there ?

If so : please try a Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st:

Thanks for that Pkshadow.

I had done the restart with add-ons disabled, forgot to state that, sorry.

Hadn't done ther refresh thing though (didn't know about that).

Same result, freezes if I try to rename (an image file at least) when I go to save it.

This looks similar to this macOS Mojave bug (please read Bugzilla etiquette before commenting in bug reports): Bug 1489785 [MacOS 10.14] Cannot choose where to download files or print because popup window always freeze

Other macOS Majave bugs are listed in meta bug 1466336. macOS 10.14 Mojave is a new OS and Mozilla developers are working on these issues.

Yes, it does indeed look similar to that one Alice. It's not quite the same as I'm seeing but I very much suspect it's caused by the same module. Well found :)
