frequent "blocked by extension" error page

[diracdeltas]

repros in Beta (1.23.51) but not Stable so appears to be a recent regression, possibly related to #14134. Also does not repro in Chrome with uBlock installed.

this seems to be happening fairly frequently in beta. ex: https://bravesoftware.slack.com/archives/C2FQMN4AD/p1616797559085900, https://bravesoftware.slack.com/archives/C3GNZANPR/p1617133973035600?thread_ts=1617125499.033600&cid=C3GNZANPR, and https://bravesoftware.slack.com/archives/C3GNZANPR/p1617194521052200?thread_ts=1617125499.033600&cid=C3GNZANPR.

i encountered it on 50% of emails i tried to unsubcribe from this morning. in one case, reloading the page made the error go away.

Adding QA/Blocked until this is uplifted to 1.23.x

@diracdeltas @pes10k @antonok-edm is this specific to desktop or does it need to be verified on android as well?

[pes10k]

I saw it on desktop frequently, i do not know if it showed up on Android (though i expect it did bc of the implementation). @antonok-edm since you did the fix, maybe you can confirm?

[antonok-edm]

@kjozwiak this has occurred on Android as well.

[kjozwiak]

Thanks 👍 Added OS/Android so this gets checked on android. I also added both QA/Test-All-Device-Types & QA/Test-All-Platform as this is something we'll probably want to check on all platforms. @pes10k @antonok-edm please change if you feel differently re: checking on all the platforms.

[antonok-edm]

This shouldn't need any testing on iOS, but otherwise that sounds good 👍
