How to install firefox, when trying says previous version detected must reboot. Stuck in infinite loop

Trying to install newly downloaded firefox (had previously removed about a month ago through programs uninstall), however when I try to run the install, it says a previous version is detected, and the system must reboot. System reboots, but install never happens, I go to run the download again, and it appears I'm stuck in an infinite loop. I can't get latest version firefox to install

I succeeded in installing Firefox after getting this message.
I went to add/remove programs to verify that Firefox wasn't on the list, then I went to the program files directory and deleted the Mozilla/Firefox directory that was left over from the uninstall.
I attempted to reinstall Firefox and, voila, it installed with no issues.
I know it can be dangerous to delete a program directory, but if you have properly uninstalled the program itself and it isn't in the add/remove list (but still exists in the program directory), deleting the parent directory for the program should affect system performance.
I have done this dozens of times over the years and never had a problem (I have NEVER deleted a system directory though. That would be a BAD idea).
I hope this helps.

I cannot re-install firefox 4 due to previous version upgrade problem

when i try to remove firefox 4 so that i can re-install it it tells me to restart my computer to upgrade the previous version therefore i cannot install

What exactly isn't working?
Due to security vulnerabilities, rolling back to Firefox 4.0.1 is not recommended.
If Firefox disabled some add-ons (especially extensions), it likely is because they include a list of compatible Firefox versions and haven't yet been updated for Firefox 5. If they worked on Firefox 4, there is a very good chance they will work on Firefox 5.
You can force Firefox to ''ignore'' add-on version restrictions by (what else) installing an add-on. Then you can test whether the add-ons important to you actually work in Firefox 5.

Please try this: Copy the files formhistory.sqlite (or formhistory) and places.sqlite (or places) if they exist and delete the entire Mozilla folder in %APPDATA% and also the Firefox folder in Program Files. [https://support.mozilla.com/en-US/kb/Backing%20up%20your%20information Please see this.]

How to fix file when it says, "Cannot open file " ". Adobe Indesign does not support the file format, a plug-in that supports the file may be missing, or file may be open in another application." It worked one second, I saved and closed the file, then tried to reopen and now it won't work. I am using Adobe InDesign CS5. It is the only version on my comp. I have tried opening on another comp & copying the file – same error comes up. PLEASE HELP

First check the version of the document with Jongware's script "Identify.jsx" (ExtendScript/JavaScript).
You can find it here:
[Ann] Identify Your InDesign File
If it is CS 5.5 or above, you need someone to open it in the version the script says and export an IDML representation from that. Another way would be to install a 30days version of CS6 or above (CC) and do it yourself.
In regards of the script showing a result for InDesign files higher than CS6:
CS7 = CC v9
CS8 = CC v10 = CC-2014 or CC2014.1

TS3694 I am unable to restore my iPhone4, I have iOS6 and latest iTunes installed and when trying to sync or back up it comes up with Error −54. How or what do I do to fix this?

I am unable to restore my iPhone4, I have iOS6 and latest iTunes installed and when trying to sync or back up it comes up with Error −54. How or what do I do to fix this?

== Error -54 ==
From an OS9 reference, error -54 is a software lock on a file or a permissions error. (Some of the old codes still apply to OSX although there is no formal list of OSX error codes.)
First, try simply restarting your computer.
iTunes Library cannot be saved (Error -54) - https://discussions.apple.com/thread/1912814
Unknown error (-54) while syncing ipod - https://discussions.apple.com/thread/1082953 - problem was locked files
Why does iTunes keep showing a -54 error when I sync my iPad? - https://discussions.apple.com/thread/3727114
Error -54 possibly related to Touch Copy - https://discussions.apple.com/thread/3727114 - cleared by deleting preferences on iPad.

Click the Firefox button, go to Add-ons, then Plugins and disable the following: 
* Fun Web Products Plugin 
* My Web Search 
Both of these are adware/spyware and cause performance issues in Firefox.
Next, click the Extensions menu link (above Plugins where you are) and remove the "Ask Toolbar".
If the problem persists, please do the following: 
#Click '''Help '''| '''Restart with Add-ons disabled'''. 
#In the next menu which appears, checkmark: "'''Reset toolbars and Controls'''". 
#Finally, click the button called "'''Make changes and restart'''".

Last but not least, some of your plugins are seriously out of date which exposes your system to exploits. Please visit the [http://www.mozilla.com/en-US/plugincheck/ Plugins Check] page and update where necessary.

In case you haven't solved this by now...
Sometimes your security software will block new programs from accessing the internet. Are you getting any alerts along those lines?
Sometimes Firefox will stall during startup and never display its window. In that case, you may need to manually "kill" the firefox.exe process using the Windows Task Manager before trying to start Firefox again.
You can display the Task Manager by pressing Ctrl+Alt+Esc. Windows 8.1 has a different display than Windows 7, so I have to go by memory. If you see a tab named Applications, check that one first. Then check Processes, and finally check Details. If you find Firefox or firefox.exe on any of those tabs, select it and End Process (or other action to shut it down).
After you are done with the Task Manager, try starting Firefox up again.

Hello Bretus,
Thank you for contacting Mozilla Support and I'm sorry this update isn't compatible with the extensions you're using.
The Kaspersky support forums mention that those extensions will be updated soon, so that they are compatible with FF25. In the meantime, we do not recommend that you downgrade your version of Firefox, but you can find instructions and download locations for previous versions here:
[[Install an older version of Firefox|Install an older version of Firefox]]
Please let us know if this solves your issue.
Cheers, Patrick

Recently, I updated to Firefox 4.0.1, and the new version disabled several of my programs, including my anti-virus. How can I go back to the previous version of Firefox?

I want to go back to the previous version of Firefox, because the new version (4.0.1 I think) that I downloaded disabled several of my programs, including my anti-virus program, because they were incompatible with the new version of Firefox. How do I get back to the previous version of Firefox and re-enable the disabled programs?

Some gestures have been removed in Firefox 4.
You can restore the zoom feature by changing the values of the related prefs on the about:config page.
browser.gesture.pinch.in -> cmd_fullZoomReduce
browser.gesture.pinch.in.shift -> cmd_fullZoomReset
browser.gesture.pinch.out -> cmd_fullZoomEnlarge
browser.gesture.pinch.out.shift -> cmd_fullZoomReset
browser.gesture.pinch.latched -> false
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
You can use the Filter bar at to top of the about:config page to locate a pref more easily.

You must be running iOS 5 on your iPad if you want to install Pages. You must be running iTunes 10.5 if you want to update the iPad iOS. So - you need to download and install iTunes 10.5 and then update the iPad software before you can install Pages.
