Change UA in the new version of Firefox on Android

As anyone who uses Firefox knows, the Android version of Firefox with a new architecture has been released for more than half a year, named Firefox Preview, and then launched Firefox Preview Nightly. Firefox Nightly also updated the new UI and architecture in February this year.

At present, there are two Firefox browsers in Google Store. The one with the name Mozilla is a new version, while the old Firefox ranking first in the search results stays in the 68 version of the old UI. It can be seen that the day of the official version update is near.

However, the plug-in support of this series of new versions of Firefox is a pain point. Currently, only a few preset plug-ins can be installed. Without the UA modification plug-in, the UA can still be modified by the following method.
1. Browser access about: config
2. Click the Add button in the upper left corner to add the name:

 general.useragent.override

3. Type selection string
4. Fill in the specific UA

If you want to restore the default UA, click Reset on the right to delete this record.
