Not enough memory is available to complete this request

Every day when I open Firefox I navigate to one specific page (aspx page hosted within my organisation) This page requires authentication, I provide the credentials and most of the time am able to access the webpage. However, I frequently get the error message "Not enough memory is available to complete this request" Once this message has occurred, I cannot access the website until the hosting server has been rebooted - be it days or weeks later.

Google chrome is able to access the web page at all times with no issues - but I would rather be using Firefox. I am running Firefox 61.0.1 (64 bit). Starting Firefox in safe mode did not fix the problem. My computer also has a very ample supply of memory (rarely ever exceeds 40% usage - and most of that is Firefox!)

I hope this gives you enough information to find the issue. Thank you very much in advance.

Please provide a public link (no password) that we can check out. No Personal Information Please !


Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

It sounds that your request includes too much data (i.e. is too long). This payload can be cookies or an URL that has GET data appended or other data send via POST. This issue can be caused by corrupted cookies or cookies that are blocked.

If you use a bookmark then navigate to the web page starting with the main page or the sign in page in case there is a problem with this bookmark.


You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Thank you so much for all your helpful suggestions cor-el, I have now attempted all of them, I also cleared the cookie cache completely. Doing all this did remove the website credentials however when I re-entered them the problem persists. I did disable the adblocker, however considering I had already tried starting in safe mode, I wasn't really expecting anything but it was worth a shot,

I wasn't able to find tools - page info in the firefox sidebar. Is there another way to reach this option?

Another thing to note would be that this website is http rather than https, not sure if that makes much difference.

Thankyou
