2.4.0 verified Fri May 01 auth: no python maintenance

pip install mozversion

Common errors

error ModuleNotFoundError: No module named 'mozversion' ↓

cause mozversion not installed or installed in a different Python environment.

fix

Run pip install mozversion in your active environment.

error ValueError: No application.ini or platform.ini found ↓

cause The provided path does not point to a valid Mozilla application directory or the files are missing.

fix

Ensure the binary path is correct and that the binary hasn't been removed. Try passing the directory containing the binary instead.

Warnings

gotcha get_version() expects either a binary path or a directory containing the application. If you pass a directory, ensure it contains application.ini and platform.ini. ↓

fix Always pass the path to the executable binary (e.g., firefox) for best results.

deprecated The library is no longer actively maintained. It may not work with the latest Mozilla application versions (Firefox 60+). ↓

fix Consider using mozversion-1 or parsing application.ini manually if needed.

Imports

get_version
wrong
```
import mozversion
```
correct
```
from mozversion import get_version
```

from mozversion import get_version

    print(version_info)
except Exception as e:
    print(f'Error: {e}')
