Mozilla Firefox automatically updated to version 32. Previously I used older version. I want to uninstall this version and again wanted to install older version. But I dont know which version I used. I never checked it. So please tell me how to know previous version I used

      The main problem is in older version I can pause and resume any downloads. But it is not possible in this new version.

Try Firefox Safe Mode to see if you can pause downloads. Firefox Safe Mode is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • In Firefox 29.0 and above, click the menu button New Fx Menu, click Help Help-29 and select Restart with Add-ons Disabled.
  • In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on Help (or click on Help in the Menu bar, if you don't have a Firefox button) then click on Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

When the Firefox Safe Mode window appears, select "Start in Safe Mode".
Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Firefox manages downloads in the Downloads folder in the Library (History > Show All History)

  • Downloads are treated as history items: clearing history removes included download items and vice versa.
  • When downloads are in progress you see an animated download button on the Navigation Toolbar showing an estimate of the remaining time
  • The Download button gets a blue highlight once all download are finished to make you aware that new downloads are available.
  • Pause and Resume can be found in the right-click context menu of an item.

But pause option is working for youtube videos.

Pause for youtube videos is totally different than downloads. Did you try cor-els steps? You shouldn't downgrade to old versions as old versions are very insecure and unstable

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
