Excessive Memory Usage When Zooming a PDF

Hi,

Just started using FF 23 and found that memory usage increase dramatically when zooming on a PDF file.

I am using FF 23 on Windows XP.

I disabled all PDF plugins, as well as most other plugins, except flash, silverlight and windows media player.

I visit this link:

http://ftp.newartisans.com/pub/git.from.bottom.up.pdf

Memory usage is at ~100-300Mb.

I zoom the PDF to 400% and memory usage jumps to ~1Gb. Further zooming in and out makes FF less responsive.

Closing tab with PDF alleviates the responsiveness issue and reduces memory usage back to 100-300Mb.

Thanks,

Vince

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • Open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension.

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

Please report back with your results.

Hi ComputerWhiz,

Problem persists in safe mode. Also of note, if I continue to zoom in and out a dialog pops up concerning the pdf.js script, asking me to Continue or Stop. Exact message is:

"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: resource://pdf.js/web/viewer.js:2674"

This problem with pdf.js seems to have been found already in bug 881974.

Maybe installing a PDF viewing plugin will fix the issue.

Hello,

In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:

  1. Go to Tools > Options (or Firefox > Options).
  2. In the Options window, select the Applications tab.
  3. In the Search field, type PDF. You should find Portable Document Format (PDF).
  4. On the right handside you should find an Action column. Use that to select your favorite PDF reader.

Did this fix your problems? Please report back to us!

Thank you.
