Since upgrading to Firefox 4, I can't open downloaded files.

I can still save files, but am not able to open them directly after downloading.

Did you ever find out what the problem was? I am having the same issue

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

Since upgrading to Firefox 4 every time I open or refresh a page everything freezes and I have to wait a minute or so for it to respond again. I'm also having problems with uploading to Photobucket and watching things via Youtube since the upgrade.

Since upgrading to Firefox 4.0 a couple of days ago, every time I open or reload a page the whole browser freezes. At first I thought it might be down to compatibilty issues with other programmes open at the time, but as the problem has persisted when those programmes aren't open I'm starting to think it's the browser itself and it's getting extremely frustrating having everything freeze every time I want to change a page.
My other problem is twofold: with Youtube nothing plays at all because the toolbar with the play/pause option simply isn't there and I am unable to access the upload function on Photobucket because likewise it won't appear. I'm assuming this has something to do with Flash but have no idea how to fix it.
I've tried

hello, often such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions. please remove all program rules for firefox from your firewall and let it detect the new version of the browser again.

Can't open downloaded files

Help! I can't open downloads from the internet or e-mail in preview. It seems to be happening with both pdfs and jpegs. It just started yesterday, and I'm not sure why. It gives me a message stating that the file may be corrupted or the wrong file type. The file type is not wrong, and it says this for files from any source even trusted ones. Any help is much appreciated!!

HI,
Assuming you are using Safari... try maintenance.
From the Safari Menu Bar, click Safari/Reset Safari. Select the top 5 buttons then cick Reset.
From the Safari Menu Bar, click Safari/Empty Cache.
Quit Safari.
Go to Home/Library/Caches/Safari and delete all the sub-folders within that one.
Go to Home/Library/Safari and delete any of these files you have there:
• Downloads.plist
• History.plist
• LastSession.plist
Restart Safari.

Since upgrading to Firefox 5, I can no longer browse for attachments in AOL Webmail, and every time I open Firefox, it asks me if Mozilla can make changes to my hard drive. I've gone back to Internet Explorer.

I upgraded to the latest version of Mozilla Firefox and ever since then, every time I open Firefox it asks me if I want to allow Mozilla to make changes to my hard drive. I have to answer "Yes" or else it won't open Firefox. Then when I open my AOL Webmail and try to browse for an attachment, it freezes up the browser window and I have to open the Task Manager to close Firefox. I have now gone back to Internet Explorer which does not have either one of these problems.

Maybe just corrupted Disk Utility preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.DiskUtility.plist
Click Go then move the com.apple.DiskUtility.plist file to the Trash.
Restart your Mac then try creating a .dmg file.

Since upgrading to Firefox 6, I can't use my autofill forms. It now has my name and address but doesn't have credit card or password information that it had before and I don't know how to input it or import it from former versions of Firefox.

I just upgraded to Firefox 5. Before when I filled in a form, I just had to click autofill and all my information was provided. I found autofill on customize toolbars and added it, but it only had my name and address, not my credit cards or passwords. Before I could click on them and change them if I needed to. I would like to input them on this version or import them from the last one so I can easily fill forms online, but I can't see how to do it.

Can not open downloaded files

when I download a file that is not a pdf file and try to open it firefox states that the file is not pdf file and tells me that it can not process it. you treat every downloaded file as if it were a pdf file regardless of what type it is.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Google Chrome can't open downloaded files

Hello.
I'm having a little problem with Google Chrome. Made package from AUR.
Everything is working fine, but I can't get chrome to open any files it downloads, I have to manually go to the downloaded file and open it.
I'm sure the answer is trivial, I just can't figure it out.
Anyone know?

Hmm... To be on the safe side make sure you have installed perl-file-mimeinfo and xorg-xprop. Also, while logged out of your account, switch to a console screen, log in and delete these two files "~/.local/share/mimeapps.list" and "~/.local/share/applications/mimeapps.list". After this I'd recommend that you delete your browser's configuration "~/.config/google-chrome" (make sure you have a cloud backup to recover all your data later, or at least backup your bookmarks and ssl certificates before doing this ).

Help! Can't open downloaded files.

I recently purchased and downloaded a program for creating genograms. During downloading, I selected "Open with Stuffit Extender" as default, but when it was downloaded onto my desktop, the icon attached to the program was a "Word" icon. Thus, Word is the Default application that is opening the program. SO, I CAN'T open a program I just paid $50 for. I don't know how to select the right application to open this program file. Some downloads are opened with Word, sometimes with Exel. Please help!! --Thank you!

Select the file in the Finder, choose Get Info from the File menu, and change the default application for that file to StuffIt Expander. Alternatively, you may be able to open it by dragging it into the open StuffIt Expander window or the StuffIt Expander icon in the Dock.

Since upgrading to Firefox 4 I can no longer send a link to a web page. I use Windows XP. Can anyone please help?

I have used Firefox for some time and have enjoyed the bsend a link feature in the File drop dwon menu. Since installing Firefox 4 this feature no longer works. I click the option and nothing happens. In preferences and applications the mailt0 icon on the far left is not as distinct as it was and the option is set to googlemail which is correct. I have an Apple mac and also installed Firefox 4 and send a link works on the mac with no problem!

You can try to delete the file mimeTypes.rdf

I can no longer place links to websites in the FF icon on my Windows 7 task bar, as I could with Firefox 4. Is it still possible? task bar since upgrading to Firefox 4. Can it be made possible?

With FF v.3 I could place links to oft-used websites in the right-click expanded Firefox icon on the task bar. It appears that Firefox v. 4 no longer provides for that feature. Can it be done some other way? Otherwise I have to open my FF homepage and click on a toolbar bookmark for the website.

>> Did you check what happens if you set the Task bar to be always visible?
No, because I do not want my Task bar to always be visible. I want it to auto-hide.
Firefox *is* maximized when this occurs. However, "maximized" window does not mean "cover up task bar", which is what FF is doing. I can maximize any of my other applications and still access the task bar as expected. For those applications, I did not have to hunt for special configuration files or anything else, because they are following what appears to be at the very least a UX best practice for Windows 7.
I definitely appreciate your taking the time to share the information that you have shared, and I have no doubt that your suggestions work as you have outlined. However, I'm seeking a user experience with FF in which I do not have to treat it differently than other applications in order to view my Windows task bar when its window is maximized. And I can view the taskbar with FF maximized, *sometimes*. Other times, it stops appearing indefinitely, across multiple sessions/shutdowns/etc.
(FYI, right now, I have FF maximized, and am able to view the Task bar, so I'm not currently experiencing this issue. I do not recall doing anything special to make it work.)
Again, I appreciate your taking the time to answer, even if it wasn't what I wanted to hear. :)
