Caveat: in the past some users have reported this negatively interfered with page loading at browser launch time in some cases ( example, example), hence why it is optional and not enabled by default in Chromium-based browsers. To remediate the browser launch filtering issue on a given webpage, you can simply force a reload of that webpage, which as a result will bring back the badge to be rendered as expected:įor Chromium-based browsers, it is possible to automate step 4 above by checking the setting Suspend network activity until all filter lists are loaded in Filter lists pane in the dashboard. Once uBO is ready to filter properly, a yellowish ! badge on a normally colored toolbar icon means that the current webpage was not filtered properly at browser launch, potentially causing the current webpage to be afflicted by ads/trackers/etc.: not being filtered in some of the already opened webpages: If additionally there is a yellowish ! badge while uBO is working toward readiness, this means network requests were fired by the browser which could not be processed by uBO, potentially leading to ads/trackers/etc. To reduce the number of reports caused by this issue which is outside of uBO's control, uBO's toolbar icon will now reflect its readiness status at browser launch.Ī yellowish toolbar icon means that uBO is currently loading all filter lists into memory and as such is not ready to filter properly: This leads to numerous reports of 'uBlock stopped working', which are simply caused by the fact that at launch time the browser started to load webpages before uBO was ready to filter properly (because the filter lists were not fully loaded in memory). UBO's readiness at browser launch time is a particularly prickly issue on Chromium-based browsers.
