tinymce-5.x-1.9 Drupal Module not compatible with FireFox 2, 3

When enabled, I get blank pages when trying to add/edit all kinds of content.
The page has a link top-left to "enable rich text editing" - for the rest it is a blank white page. Ctrl+F5 has no effect.

This bug applies to:
- Browser: Firefox 2, 3.01 (IE6 produces a page with the editor enables properly)
- TinyMCE engines: tinymce_2_1_2 , tinymce_2_1_3 , tinymce_3_1_0_1

Corrective Processes I tried:
- Uninstall + Re-install of module, tinymce engine plug-in -> no effect
- Varying various settings -> no effect
- Applying no-cache patch as indicated in some listed issues -> no effect

TinyTinyMCE displays properly in Firefox2,3 with plugin (tested 3_1_0_1)

=> This bug seems to have become visible as a result of recent Firefox 2, 3, updates
( I have an older site where mod1.9 + 212 worked fine)

Conclusion:
TinyMCE Drupal Module 1.9 seems to have become incompatible with Firefox 2,3 :-((

Please do fix this soonest, as this I consider this a "must-have" module for most sites.

Thanks and Good Luck!
