Scrollbar in Firefox blocks the drag down handle in grid view

Description of issue

If you are using Mozilla Firefox and are trying to drag down cells in grid view which are located at the very right side or the very bottom of the table, you might notice that the scrollbars block the handle used to drag down as shown below.

Workarounds for issue

This behavior is due to a decision made by Mozilla Firefox and would require changes to the underlying library we use for rendering the grid view table. At this stage, neither we nor the library maintainers are able to implement a fix, but we’ll continue to monitor for any updates.

Copy and paste instead

The simplest workaround is the use the copy and paste functionality instead. This can be done by clicking the cell you want to copy, press Ctrl + C, and then highlight the cells that you want to paste the content into and then press Ctrl + V. This would achieve the same functionality as dragging down the cell.

Revert Firefox back to classic scrollbars

If you would rather use the drag down functionality instead, you can change the Firefox settings to use classic scrollbars instead of their new overlay scrollbars. You can use the following steps to do so:

1. Navigate to about:config in your Firefox browser.
2. If you see a Proceed with Caution warning then simply click Accept the Risk and Continue.
3. In the search bar at the top, type in overlay-scrollbar.
4. You will want to find the two settings which are named widget.gtk.overlay-scrollbars.enabled and widget.windows.overlay-scrollbars.enabled and set both of these to false by clicking the button. It should look similar to below:
   
5. Restart your Firefox browser.

Your scrollbars will look a little different now, but you will be able to use the drag down functionality again for cells right on the edge of the tables.
