all the options and parameters provided by the binary firefox to firefox-bin
are displayed eg.,
for Firefox-132:
/usr/local/lib64/firefox132/firefox-bin -contentproc -parentBuildID 20241021175835
-prefsLen 24975 -prefMapSize 253763 -appDir /usr/local/lib64/firefox132/browser
{1ac1038c-19a2-4a74-8e03-83da21315c92} 15183 true 1 socket
while for firefox-95:
/usr/local/lib64/firefox95/firefox-bin -contentproc -childID 1 -isForBrowser
 -prefsLen 1 -prefMapSize 240375 -jsInitLen 278884 -parentBuildID 20211218203254
 -appDir /usr/local/lib64/firefox95/browser 7726 true tab

Since Firefox version 100 the last argument for firefox-bin (last argument for its option -appDir) is `true 1 socket` whereas in previous versions Firefox 95 and earlier this was `true tab` In Linux Fedora fc20.x86_64 the version 95 and earlier work but starting from the version 100 Firefox fails to display GUI (there appears only empty window created by Gnome and titled Firefox). All the requiremnts concerning software versions have been satisfied. Therefore I suspect that this difference in the last argument may indicate the cause of this problem. Hence my question: Is it possible, without recompilation of Firefox (now 132), to provide this last argument as `true tab` instead of `true 1 socket` for option -appDir of firefox-bin ?
