@Mattches @sampson @rebron2000

Please, take a look at this thread whenever you have the opportunity. Multiple users are reporting the same issue, the issue is not present in a private window and/or a new user profile. I’m not sure what might be causing the issue as I can’t reproduce it on my end.

Here is what we know about the issue so far:

• Clearing browsing data doesn’t resolve the issue.
• Disabling extensions doesn’t resolve the issue.
• Disabling Brave Shields doesn’t resolve the issue.
• Disabling Hardware Acceleration doesn’t resolve the issue.
• Resetting via brave://settings/reset doesn’t resolve the issue.
• The issue is not present in Google Chrome.

Known workarounds so far:

1. Using a private window.
2. Creating another user profile.

The solution so far:

Gmail as of Aug 13 will not open in Standard mode, it forces HTML mode only on Brave Browser, please help!

OK, pretty simple, don’t be put off by all the stuff in the console window. In your regular profile go to the Basic HTML Gmail tab and press the following keys together. Ctrl-Shift-I (that is the letter I not number 1). A section will open up, usually at the bottom of the page. It is used by developers to debug but you don’t have to concern yourself with any of it, just let it sit there. The tab that you’re viewing - Gmail - will be resized and be a bit smaller, it might look like the page is …

Oh how odd, this fixed it for me as well. With the dev tools open, just clicking the “standard” link didn’t work, but Ctrl clicking to open in a new tab did. I use the “start from last time” setting and my gmail tab is never closed. I wonder if that had something to do with it. Very, very odd! Thanks @AgentStarling Edit - just to note, the original tab still won’t load normal HTML, but the new one loads it fine every time.

There’s, actually, a simple solution: Open the Dev tools (Ctrl + Shift+ I); Navigate to the “Application” tab; Scroll down the left panel to the “Cache” section; Remove everything inside “Cache storage” and “Application Cache.” Have fun.

Ok, it didn’t work for me either until I “unregistered” every service worker for the site. Steps to unregister service workers: Open the devtools as mentioned in many posts above Go to the “Applications” Tab Select Service Worker You should see a list of service workers with blue links to View Network requests, Update and Unregister. — Click “Unregister” Follow this step for any and all mail.google.com service workers (this is if you have multiple gmail accounts) Do refresh didn’t immediately…

I had the same issue for a few days and today I had the idea to change the User Agent, just in case Gmail doesn’t accept Brave anymore… Guess what ? It worked… I use now a Chrome 90 / Win10 UA thanks to User-Agent Switcher and Manager extension.

Not sure if this will be helpful, but here is my experience: I installed Brave a few days ago to replace Chrome (I also uninstalled Chrome). I can log into my Gmail account fine… but the mobile phone (HTML) view is displayed. Here is the sample URL when I log in and the HTML view is on the screen: https://mail.google.com/mail/mu/mp/719/#tl/Inbox If I remove mu/mp/719/#tl/Inbox And refresh the screen, then the regular view displays, and my URL looks like this: https://mail.google.com/mail…

Using an unsupported browser

If you use Google Workspace on an older or unsupported browser, some features might not work, or an application might not open. For example, on an unsupported browser:

• You may be able to view, but not update, your calendars.
• You may be redirected to the basic Gmail interface.
• Drawings and presentations in Docs editors may not display properly.
