Karlston posted a topic in Mobile NewsAbout:config is blocked in Firefox Preview Stable and Beta Mozilla is working on a new mobile browser for Google's Android operating system. Called Firefox Preview currently, it is available as a preview version right now. As is the case with desktop Firefox, Firefox Preview for Android is available in different editions that differ in terms of stability and development progress. Firefox Preview Stable is the main version that is comparable to Firefox Stable for desktop operating systems. There is also Firefox Preview Beta and Firefox Preview Nightly for Developers. While there are not many major differences in regards to core functionality between the different editions usually, it appears that Mozilla decided to implement one in Firefox Preview that might irritate some users of Stable or Beta versions of the browser. Firefox supported the internal about:config page for a long time; it provides an interface to make advanced configuration changes directly in the web browser. Firefox for the desktop and mobile supported it until now. When you try to load about:config in Firefox Preview Stable or Firefox Preview Beta, you are greeted with a "cannot complete request" message instead. The page states that "additional information about this problem or error is currently unavailable", and there is a "try again" button to retry loading the page. It is unclear at this point if the change is deliberate or if Mozilla plans to unblock the page before final release. As it stands, Firefox Preview Stable and Beta users cannot make use of about:config to make changes to Firefox's configuration. If you compare that to the current Firefox mobile browser for Android, which supports about:config, you have to wonder whether that is an intentional change or something that just has not been implemented yet. It seems expected behavior judging from the post of a contributor on the official GitHub project website: This is expected behavior from GeckoView. Fenix does not control access to it. When Fenix nightly is released it will have access to about:config for users that have that requirement. Closing Words It is probably not a good idea to release Firefox Stable or Beta versions for Android without support for about:config as users who used it in the past will certainly be disappointed that the feature is not available. It is also difficult to justify considering that the previous Firefox for Android supported it and desktop Firefox Stable supports it as well.

The Firefox web browser displays a list of top sites on the web browser's New Tab page by default next to a search field, highlights, soon downloads, and recommendations. Mozilla changed the New Tab Page in Firefox 57 and introduced something that it called Activity Stream on it. Top Sites are displayed just below the search form on the New Tab page in the Firefox browser. Firefox displays a single row of websites and services by default. Top Sites are sites that are visited the most. Firefox gives users options to pin sites so that they become available. Each site you pin to Top Sites takes away a spot that is filled automatically by the browser. You can also dismiss sites to hide them from the Top Sites listing and rearrange Top Sites using drag and drop. How to add more Top Sites rows to Firefox It is easy enough to increase the row count to two as Mozilla added an option to do so. A click on the cogwheel icon on the New Tab page displays options to hide any element on it. You find the "show two rows" option under Top Sites and a second row is added to the Top Sites listing when you check it. Note: Mozilla plans to move the preferences from the New Tab Page to the Settings. A click on the icon on the New Tab page opens the Firefox preferences then where you can make the change. Two rows of Top Sites may be sufficient for some Firefox users but what if you want more rows to display even more Top Sites on the New Tab page? Firefox comes with built-in functionality to extend the Top Sites listing to more than two rows. You need to modify the web browser's configuration for that: Load about:config?filter=browser.newtabpage.activity-stream.topSitesRows in the Firefox address bar. Double-click on the preference browser.newtabpage.activity-stream.topSitesRows and change its value to the desired number of rows and click ok. Check the New Tab Page to see the change right away and modify the number of rows accordingly if needed. You can undo the change at any time in the following ways: Right-click on the preference on about:config and select "reset" from the context menu. Double-click on the preference and change the value to 1. Ghacks.net
