general.useragent.override

You can set your mobile Firefox to identify itself using a different user agent string. This is a little involved. (1) On Firefox for Android, select and copy the following if possible to avoid excess typing: general.useragent.override (2) Open a new tab to '''about:config''' (type about:config in the Awesomebar and tap the go arrow or tap Enter). ''You may want to bookmark this for easier future access.'' (3) To filter the view, in the search box, type '''useragent''' and pause while Firefox filters the list (4) Tap the large "+" button to the left of the search box to add a new setting (A) The name of the preference should be '''general.useragent.override''' It's easiest to paste. If you are typing it, watch out for autocorrect inserting spaces or changing capitalization, and make sure to clean that up. (B) On the right side, tap Boolean and in the popup change it to String (C) Temporarily assign any text (more letters is better), e.g., aaaaaaaa (D) Then click Create (5) In a separate tab, open the following page: https://www.jeffersonscher.com/res/jstest.php (6) Use menu > Request Desktop Site In the page, the user agent string in red should change from referring to aaaaaaaa to X11/Linux. (7) Select and copy the user agent string (8) Switch back to the about:config tab in Firefox, double-tap the temporary text, select it, and paste the user agent string you copied, then tap any other preference to finish the edit. Now if you switch off Request Desktop on the test page, you should still get the same page and user agent. If you test that on sites you normally visit, does it work? If you need to undo the change, tap the "Reset" button for that preference and Firefox will delete it.

Thank you soooo much!!! Really appreciate your time!
