Suddenly (after 27th Oct) Firefox will not upload files larger than 500 KB to my website (Have to go to Google Chrome to do it): why? (A refresh did not work.)

If I upload files using Firefox:

Up to 27th Oct, I have had no problems uploading files to my website (WordPress - 2 MB file limit). Since 27th Oct...

On my website, anything below 500 KB goes up. Anything above 500 KB doesn’t – no matter how often I try. On Flickr, most things under 500 KB go at the first time of asking, while most things over 500 KB take 2, 3 or 4 goes, but do go eventually. On Dropbox, a big 25 MB RAW file goes up, no problem.

If I switch to Google Chrome – no issues – everything goes up on the website no problem.

I tried a refresh of Firefox, but it didn't help.

When I try to upload a file more than 500 KB to my website, the error message just says 'HTTP Error'

I am not a tech savvy person!

Thanks for the help. I was going to get my IT friend to do the recommended changes later today. However, this morning, Firefox did an automatic update. It mentioned the reason being stability issues. After the update, I tried uploading a 1 MB file and it went up with no problems. So, it looks like the problem has been solved by Mozilla.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) to see if that helps.

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

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