Hi

To help us to look into this further, please can you type about:support in the address bar and select the Copy raw data to clipboard button at the top of the page (you may need to zoom in to see that button). Please can you then paste the results in a reply to this thread.

If possible could you also install Firefox for Android Nightly from the Google Play store (it will not alter the data stored in the Release version - that will stay there). Type about:config into the address bar and search for the gfx.webrender.software preference. Use the controls to change that to true and try the website you were trying to use before again. Does this is now work?

WARNING from the moderator team: Changing Firefox preferences from the about:config page can sometimes break Firefox or cause strange behavior. You should only do this if you know what you're doing. Please read Firefox Advanced Customization and Configuration Options to learn more.

Two further comments

1. I was unable to get the nightly version for Android to download. Don't know why.

2. I have discovered that the blanked-out areas go away if I zoom in on the screen (swipe with 2 fingers). The blanked-out areas come back when shrunk back to fit the screen.

Thank you for letting us know. Please follow the bug report I linked to above for progress on this issue.

Hi
