## Description Using `* { font-family: MYFONT !important; } ` userstyle in Stylus 1.5.22 (Userstyle Manager) should be able to override the font used on the webpage, prior to 1.39.109, i.e. 1.38.119 works fine. On 1.39.109 however, brave does not respect the font override and continued displaying the font prefered by the webpage. ## Steps to Reproduce 1. Update to 1.39.109 (Chromium 102.0.5005.50) 2. Any page applied userstyle to override font failed ## Actual result: Unable to override font. ## Expected result: `* { font-family: MYFONT !important; } ` should work as expected to override the font. ## Reproduces how often: Always ## Brave version (brave://version info) ` Brave 1.39.109 Chromium: 102.0.5005.50 (Official Build) (64-bit) Revision f6e2cf8f59ec714bdcff8499991d55898875f287-refs/branch-heads/5005@{#648} OS Windows 10 Version 1809 (Build 17763.2803) JavaScript V8 10.2.154.4 User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.5005.50 Safari/537.36 Command Line "C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe" --disable-client-side-phishing-detection --disable-domain-reliability --enable-dom-distiller --no-pings --component-updater=url-source=https://go-updater.brave.com/extensions --origin-trial-public-key=bYUKPJoPnCxeNvu72j4EmPuK7tr1PAC7SHh8ld9Mw3E=,fMS4mpO6buLQ/QMd+zJmxzty/VQ6B1EUZqoCU04zoRU= --sync-url=https://sync-v2.brave.com/v2 --lso-url=https://no-thanks.invalid --variations-server-url=https://variations.brave.com/seed --variations-insecure-server-url=https://variations.brave.com/seed --flag-switches-begin --flag-switches-end Executable Path C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe Profile Path C:\Users\f\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default Variations AdRewardsStudy:NextPaymentDay AdServingStudy:DefaultAdNotificationsPerHour=10/MaximumAdNotificationsPerDay=100/MaximumInlineContentAdsPerHour=12/MaximumInlineContentAdsPerDay=60 BraveAds.UserActivityStudy:Triggers=EMPTY/Threshold=0.0/IdleTimeThreshold=5 BraveDebounceStudy:Enabled ConversionsStudy:NewDefaultPattern Default1pBlockingStudy:Disabled EphemeralStorageStudy:Enabled ExtendedVariationsSafeMode5:SignalAndWriteViaFileUtil5 FirstPartyEphemeralDomainBlockStudy:Enabled ForceDisableBlinkFeatures:Enabled NativeCosmeticFilteringStudy:Enabled NavigationThreadingOptimizationsCompat:Disabled PartitionBlinkMemoryCacheStudy:Enabled PartitionConnectionsByNetworkIsolationKeyStudy:Enabled PermissionLifetimeReleaseStudy:Enabled RequestAdsEnabledApiStudy:Enabled SpeedreaderReleaseStudy:Enabled ` ## Version/Channel Information: - Can you reproduce this issue with the current release? yes - Can you reproduce this issue with the beta channel? not tested - Can you reproduce this issue with the nightly channel? not tested ## Other Additional Information: - Does the issue resolve itself when disabling Brave Shields? no - Does the issue resolve itself when disabling Brave Rewards? no - Is the issue reproducible on the latest version of Chrome? not tested ## Miscellaneous Information: N/A

Shields breaking text/fonts on some websites

## Description Since version 1.39.111 the text on some websites started to look wrong: wrong font, wrong spacing, wrong line hight, etc. It only happens on some sites. So far I've only noticed it happening on pages without custom fonts (eg: happens on old.reddit.com with the default theme, but not when a custom theme with a different font is used. the new reddit UI is also fine). This seems to be related to Shield's "Block fingerprinting" option (standard or strict) as disabling it fixes the problem. ## Steps to Reproduce 1. Enable Shields and set "Block fingerprinting" to "standard" or "strict". 2. Reboot the browser. 3. Access a page like: https://old.reddit.com/r/worldnews/ Note: Only seems to happens on pages without custom fonts. A sub (eg: Brave's sub) with a custom theme looks fine (unless you disable custom themes on your reddit account). Please note that this issue is not limited to reddit. ## Actual result: Wrong spaces, line height, wrong font (number 26): <img width="283" alt="Screenshot 2022-05-26 at 22 06 56" src="https://user-images.githubusercontent.com/23439751/170583038-c8afeada-6fdf-4702-a698-ce5dc1a88161.png"> Wrong font: <img width="1496" alt="Screenshot 2022-05-26 at 22 28 50" src="https://user-images.githubusercontent.com/23439751/170583225-86f4d9be-59be-47f8-a246-d43bfc520fa0.png"> ## Expected result: Correct spaces, font, etc: <img width="223" alt="Screenshot 2022-05-26 at 22 08 46" src="https://user-images.githubusercontent.com/23439751/170583053-aeb483ae-9d49-469c-a3b9-bc0e40c5a349.png"> Using the correct verdana font: <img width="1496" alt="Screenshot 2022-05-26 at 22 29 14" src="https://user-images.githubusercontent.com/23439751/170583295-2f578c22-0fa3-4ee7-8e42-57ccb320d08d.png"> ## Reproduces how often: Most of the times the text looks wrong. A browser restart is sometimes needed after enabling Shields' privacy option to see updated results. ## Brave version (brave://version info) Tested with: - Stable: Version 1.39.111 Chromium: 102.0.5005.61 (Official Build) (arm64) - Nightly: Version 1.41.17 Chromium: 102.0.5005.61 (Official Build) nightly (arm64) <img width="697" alt="Screenshot 2022-05-26 at 22 39 25" src="https://user-images.githubusercontent.com/23439751/170584542-40bc8e85-2d35-4409-abd6-abdabdf8ee60.png"> <img width="697" alt="Screenshot 2022-05-26 at 22 39 13" src="https://user-images.githubusercontent.com/23439751/170584550-b48185bd-10f5-497c-b2fe-f9750f55bce0.png"> Machine: - MacBook Pro (16-inch, 2021) - Apple M1 Max - 32GB RAM - macOS Monterey 12.4 (stable) and 12.5 (beta) According to this comment, it's also happening on Windows 10: https://old.reddit.com/r/brave_browser/comments/uwuad0/release_channel_139111/i9x2ow8/ ## Version/Channel Information: Can reproduce the issue on the current stable and nightly versions. ## Other Additional Information: No issues when the privacy option of Brave Shields is disabled. ## Miscellaneous Information: More reports on reddit: https://old.reddit.com/r/brave_browser/comments/uwuad0/release_channel_139111/i9ty88d/

Just curious if you experience any changes if you enable/disable fingerprint blocking in shields? Could you test and post an update?
