Forum:Firefox 8 incompatible with editing some Wikia sites

A couple months ago the version of Firefox I was using (in the 7 range) corrupted and I had to reinstall and I ended up installing the new Firefox 8. Since then I've found I cannot edit some Wikia pages, particularly those on the TARDIS Index File, but I've encountered this elsewhere. When I click edit a bunch of coding comes up in the edit field (doesn't matter if I use Source - which is my preference - or Visual tabs). And then when I save the edit (i.e. if I ignore the coding and just add the text) the page saves with all the coding visible, wrecking the format and forcing me to revert the edit. I've had to resort to using another browser for editing (Safari) which is annoying because generally speaking Firefox is friendlier when it comes to displaying Wikia pages. Having said all this, it is not happening with all Wikia pages - for example I'm having no problems editing this page in Firefox 8. Has anyone else encountered this problem? A Firefox 9 is now out but I'm hesitant to install it because I might find I can't access Wikia at all (plus I always lose some functionality when I upgrade software - Firefox 8 also disabled several plug-ins I'd gotten used to using, so Firefox 9 might cause similar problems if I install). 68.146.72.113 19:27, January 8, 2012 (UTC)
