Firefox (17.0.1) no longer works with Adobe 10.1.4 and MAC OSX 10.7.5 Lion? Online disc. say Adobe 11.0 will not fix? Suggestions?


I can open pdf files in safari, however my office products work more effectively with Firefox. Currently the firefox browser shows a blank screen when I try to launch pdf file within my work program. So I would really like to be able to use firefox as the browser. Is there an update or fix that will work? Although I am currently on Adobe 10.1.4. after reading online discussions it suggests that 11.0 doesn't work either and so I hate to try another update. Everything was working fine with old Adobe version (which I don't know which one that would have been and not sure if and/how to get it back) until last Sunday when my husband decided to update my Adobe without my permission. Can anyone help?

Update to Adobe 11 (it's more secure and better anyway, so you should update). Then try again.

You can disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.
