Firefox Support Forum

I use Windows 7 Home Edition and Firefox .What is the easiest way to transfer Firefox from my Old Computer to my New Computer saving all my ADD ONS ,SETTINGS AND FAVOURITES

I can't open anything in my Downloads list. I've tried resetting firefox and I've also tried everything in your article "What to do if you can't download or save files" but nothing helps. I tried to upgrade to the latest firefox to see if this helps but once I've hit the Download button, 1 minute later it appears in my downloads list and... same issue... I can't open it to run it! It's like it's crashed, because no amount of clicking on a download will activate anything. It seems like the Downloads list is dead! Also, (and I think this is linked), I cannot save web pages. I go though the motions and it looks like it's doing the right thing but the pages don't save - they just disappear into the ether! I'm on Windows Vista and have been downloading things happily for years, but suddenly this problem has occured and I've run out of ideas now... Please help!

The main use of the PC in my living room is as a media center. My GUI (Plex) runs in the browser and plays videos with VLC via a custom addon. Currently it is also used for browsing from time to time and I need to keep that part of it secure. As Mozilla is about to break all my addons as well as force me onto 64 bit, I've no choice but to stop updating Firefox on that PC.

I found a old post (3 years old) about running two different versions of Firefox at the same time. https://support.mozilla.org/en-US/questions/974208

Is it still possible to do this? Does the same methods still work?

I want to freeze my current 32 bit Firefox at v54.0.1 and use it only for local content. (I've already disabled updates on it)

Then I want to then install a second 64 bit Firefox v55, use it for internet, and allow it to update normally.

If this isn't possible I'll just have to switch to a different browser.

I have read too many misleading and uniformed statements about installing and enabling Flash Player in Firefox. However after reading way too many comments one little tidbit made as an afterthought by a respondent GOT MY ATTENTION. it said, " be sure Firefox is closed [as well as IE]. Everyone knows to down load and install one has Firefox OPEN because you go to the arrow and click on the executable. WRONG. You must close Firefox and go find the executable somewhere in your download folder and execute it from explorer. The Voila it all works fine and Shockwave shows up in your Add-ons ready for action. Hope this helps all.

Hi, I'm getting an error "The program can't start because mozglue.dll is missing from your computer. Try reinstalling the program to fix the problem." when launching Firefox. Firefox was working last night. I have Windows 7.

I have uninstalled Firefox and reinstalled it from latest version from Mozilla website but got same error when I launched Firefox again. I have tried reinstalling Firefox about 4 times but this did not help to fix the issue.

Would it help fix the issue if someone provides me a copy of mozglue.dll to place in C:\Program Files\Mozilla Firefox\ on my computer?

Please help. Thanks.

Regards, Andrew

Request for information added here where it will be seen

Hi, there seem to be a couple of other users affected by this reading this thread (judging by 30 users clicking "I have this problem too").

It would be helpful if you could chime in as well & report what antivirus software (& sandboxing software, if any?) you are using on your system. Also if you take a look into your Firefox program folder: Is the mozglue.dll file actually missing there?

Firefox program folder is in one of these locations:
Windows 32-bit users: C:\Program Files\Mozilla Firefox
Windows 64-bit users: C:\Program Files (x86)\Mozilla Firefox

Java is installed and running:

java -version

java version "1.7.0_45" Java(TM) SE Runtime Environment (build 1.7.0_45-b18) Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

created symbolic link - pwd /home/kramer9/Images/firefox/plugins [kramer9@oc6138011027 plugins]$ ls -al lrwxrwxrwx. 1 kramer9 kramer9 49 Dec 13 12:34 libnpjp2.so -> /opt/java/64/jre1.7.0_45/bin/lib/i386/libnpjp2.so

Still no luck - ideas?

Found existing message that Firefox 53.2.0 is available for XP, but the download link on the page only offers v. 57. I'm trying to download on a Linux machine that is running v.40 which I will update, but still need the version for XP. The XP machine is airgapped so can't download directly.

Firefox did not function anymore then I removed it en now i want to reinstall but this message came:

7 zip

Can not create temp folder archive

How can i reinstall Firefox???

I have a shared WiFi internet connection with 54.0 Mbps speed. Internet speed is good but Firefox installer downloads Firefox at very slow speed. It takes about 10 to 15 minutes in downloading Firefox. Please fix the problem if it is occurring through your end, else do tell me what can I do to get it better. Thank you.

New computer running Win 7. Install FF no problem. But then the icon disappears from the Start Menu and from the Taskbar.

When I go to the program location C:\Program Files (x86)\Mozilla Firefox there is only the generic icon for firefox.exe.

Program seems to work fine, but this is annoying. Thanks for the help.

I tried to remove Yahoo by uninstalling and re-downloading the latest version as previously instructed but it is still there on the new installation. I am not a technician and do not want to start searching or removing registry places. I never asked for this service to be placed on the Mozilla page and I watched very carefully when downloading the program but there was no tick or untick place. It would be appreciated if someone could please explain in simple terms how to get rid of it PERMANENTLY

When searching for something, a Search Engine called 'Delta' popped up. Despite ticking a box to say NO I didn't want it, I've now got it on both Firefox and Google. I've followed as many instructions as I could understand and removed it from Add-ons but IT WON'T GO AWAY. What on earth can I do to get my settings back to normal and rid myself of the dreaded DELTA?

(NB. Whilst trying to comprehend various instructions I disabled all my add-ons and now can't see how to enable them again.)
