Chameleon breaks Google Drive

[thelmexx]

Expected Behavior

Google Drive (drive.google.com) working correctly, able to navigate folders and open documents.

Current Behavior

Unable to leftclick on folders to open them, nor leftclick on document to open them. Disabling the addon and refreshing the page fixes this.

Hi @thelmexx,

I'm not able to replicate this bug, however, v0.20.3 may have resolved your issue. Please let me know if you're still experiencing issues after updating.

[thelmexx]

Still happening as of v0.20.3, including with all other addons disabled. Specifically I can't navigate between folders and files on the drive interface, while I can still use side menus, e.g the trash menu.

Had the same issue. Basically, one can log into Drive. The navigation is present, as well as surrounding elements (around the all 4 edges of the page), however, the actual directory and/or file list would not appear. Just blank -- in the middle of the page.

I came to the conclusion that it was Chameleon after process of elimination with my addons.

Initially, I thought it might be related to enabled "Protect Window Name". Wasn't it.

Luckily, I recalled the last thing I changed from the day or two before.

Switching Timezone back to "Default" instead of a specific timezone fixed the issue for me. Just switching the timezone back and forth, and then force refreshing the page, will instantly cause or fix the issue accordingly. Hope this helps!

Thanks @ck9ine. That seems to be the cause of the issue. I've found where the issue is located but I'm not sure yet why it breaks.

[ck9ine]

To add, the specific timezone that caused the issue was my exact timezone for my geographical region (or maybe it was an hour off due to daylight savings). Just in case one might think that it's some sort of IP/timezone validation check on Google's part.

Opening google sheets with chameleon enabled (even if google is whitelisted) presents me with this error:

From top to bottom:
'A Problem occurred. Reload.'
'An error occurred on the server. Click on the reload-button in your browser to reload the page.'
'File cannot be loaded.
Try again or send a bug report.'

https://docs.google.com/document/ works.
https://docs.google.com/spreadsheet/, ../presentations/ and ../forms/ sometimes work, reloading them a couple times fixes them if they don't work.

@keraldi That's interesting. Can you post your settings?

I took the liberty of removing all rules except for the google one.

@keraldi This was a bug with iframes and whitelist handling. It has been fixed in v0.20.5.

@thelmexx Google does some funny things with the Date object that cause the timezone spoofing implementation to break. I've added Google Drive and Google Docs to a permanent whitelist in v0.20.5.
