Firefox iOS with patch version is not parsed correctly

[brettdh]

A useragent with FxiOS/1.2.3 will not be parsed correctly; patch will be .3 and patch_minor will be 3.

The reason is that the regex for FxiOS uses capturing groups that include the . for both patch and patch-minor.

Example with Python:
