blank page

Posted

on site polishburger.pl I have blank page. It becomes blank after it's loaded. I can click links - mouse cursor changes. Disabling hardware acceleration, safe mode, refreshing firefox, disabling tracking protection, disabling addons does not help - always page becomes blank as soon as it loads = less than 1s.

I'm getting hungry.

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, 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). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Refreshing Firefox {web link} is a LAST RESORT ! !

Refreshing Firefox -- easily fix most problems

If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks and open tabs. Everything else, like user settings and add-ons, are removed. Note: Refresh saves your old profile to the desktop in a folder called Old Firefox.

Just these two pages so far. I tried to refresh firefox. All the steps I've found in another posts about blank pages. Refreshed firefox, then no hardware acceleration, then disabled all addons, then safe mode, then incognito mode and still blank page.

Could you check these two sites?

I did and had no problem.

The next normal step is to Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

Nah... "safe mode" causes more problems than it solves.

I manually removed ~/.mozilla directory and it started to work. After setting up sync it stopped working again. Yeah - it's one of addons probably... BUT I disabled all addons and the page is still blank. So it's not an addon - it's something else that is synced.

Although I tweaked in the past some flags in "about:config" but I never added any variable to syncing as it would cause problems on all of mine computers at once... and it would be hard to find out which variable caused the problem... just like now (:

So the status is: - page is not blank before sync (clean profile) - page is blank after sync (disabled all addons by hand) - page is blank on 2 of my computers (archlinux) - did not add any variables to syncing - page works for everyone else

Hi CapSel, I am on Firefox 66, so I can't replicate your setup. If you try any of the following after the page turns white, does it make any difference?

  • Tap the Esc key
  • Change the zoom level, for example, by holding down Ctrl and tapping the + key once or twice (with Ctrl help down, tap - once or twice to zoom back out)
  • Change the shape of the tab content area, for example, by dragging the right border of the window to the left (if it's a resizable window) or by opening the Bookmarks Sidebar (Ctrl+b)

I've disabled hardware acceleration and restarted firefox. No effects with: - esc key - zoom level by keyboard only or by ctrl+scroll - changing size/shape of window - moving tab to new window - ctrl+shift+r

I'm using Xfce without compositions in window manager - no shadows, etc

The page is there - I can click links, cursor changes shape, I can go to menu to order... But it's all just white. Inspector from dev tools does not detect any ... layer (div/span...) on top except elements that are just there in another browser.

Hmm, if you have rules out the extensions, maybe it is one of the preferences that sync'd over. It's difficult to think of a relevant one.

Does Firefox using the same Sync account work on another system, or is this Sync account just for this one system?

There are some sites that do a fade-in effect that sometimes fails. Yours is a bit inside out, in that the site appears and then disappears, and then doesn't reappear. If you use the Page Inspector to check the body, does it have a rule similar to:

opacity: 0

which could explain why everything in the page is rendered transparent? Assuming that is the explanation, I wonder why it is persisting?

Nothing with "opacity" BUT... I've found that if I remove last element in body the page shows! YEAH!

But how is this possible? Here is a Node that I delete with devtools inspector:

The element has a transparent background image in front of a transparent color, so it shouldn't turn solid white. Very odd.

Does yours match mine? You can right-click > Copy > OuterHTML, then paste, then remove the angle brackets after pasting:

div class="watermark__overlay" style="position: fixed; inset: 0px; background: rgba(0, 0, 0, 0) url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAAcUlEQVQ4jY2TOwIAMARD0/sfWlcqjw6G1icRSNJ5LSJORLS/7Esx3UmJFuBNIiSK0w/68q7JhDwAMXWHii246g7VFPbjo6T2TwxQ9c5ipzu2sW0cMSga/IzQLVMpMAlFI20aTGOku9BCbxTRavBzwtkucA2IhyxBxBUAAAAASUVORK5CYII=") repeat scroll 0% 0%; z-index: 5000; pointer-events: none;"
